Air Cleaning Technologies &n Intelligent Controls for IAQ and Energy Efficiency
good afternoon my name is Jensen Zhang I'm the executive director of the syracuse center of excellence in environmental and energy systems and welcome to this spring research and Technology forum we try to host one every month i know we also have many people joining on the web energy agencies Annex 1780s so this seminar um major research project collaboration in Services University and we should look at basically three objectives and then even different the type of air we have in order to use evaluated to some type of Technology but also for people and regions and we will see the results from the first two of the foundations and second objective results approach uh for teaching them so a lot of people so to optimize the ventilation of our community and also based on the applicants so that's the second objective is development employment third objective is to explain the payments to the citizens Technology Insurance and to see what's the impact of these controls on a human performance performance guys the productivity and also the perhaps and also we perceived based on the argument in December that's still an objective medical service uh images and he has been with Su for probably six years now receiving this master degree from the Department of Defense engineering Kingdom this PHP salaries so he has been involved with several research projects including swing International Energy Agency for options foreign uh so this is what is the channel in progress on information their mission to recruit uh both in primary Mission Computing materials apprentices but also during the secondary conditions which is foreign foreign [Music] of distribution [Music] [Music] um so first I'm talking about the investment investors have I mean we will put a new member but it doesn't mean to be able to replace the victim method we just depending on the agency uh what we can obtain from this kind of the model information so with which team standard covers or logs from the sort of media the filter and also for different type of revolutions it also have some specific standard like program of the uh last year and for our uh uh we selected the one that we can't have which is accommodate for the possible air cleaner and compared with the durable documentation uh like first the Bluetooth Source the decade have rejected rejected at the very beginning and today long time it can be taken information and with the using of their finger so that is very stable contribution of the pollutants which also due to the method they are very high initials and concentration we should maintenance over a stress or challenges also due to the tax Network there is a lot of the second block chamber for this special chamber and the uh because it is a new one so for the new version we focus on how to simulate the real organization of the air cleaner which I mentioned in the way foreign [Music] [Music] we have achieved with the Innovative application so here is our environmental control chamber we can control the temperature humidity ventilation of the chamber and New Balance will build a room which is volume uh like 13 cubic meters and would take the table laptop and management device to make automation from from the student and under this condition the service was covered by the the floor covered by the Target and the feeling and the war and independent things so everything means um so we rejected with the Bluetooth at the um provider and the review the integral space like it will distributed by the user and also to instructional further make sure because we'll make information and the average computation um So based on this uh that up we have the all the equipments we use for the micro generation music generation photo monitoring and also available scheme well [Music] um so the second second stand forwards were elected at the starting page for the first injection uh to say okay what is the challenge competition right before um third example would that means after we turn around here so by comparison by compared with the two conditions we can obtain the performance of everything but what is the reduction of the people in Allegiance foreign [Music] part of this foreign physical and function and have a future and the order indicating a lot of the errors from which it works there for for this case so from other elements the computer first and then let's talk about it so this is the how we name the silver covered uh total instincts in Technologies which include me to have a future application annotation and the partner to supplement Technologies limited for the negative buildings foreign in the room presenting the ionization according to be doing the particles but here to be able to relax okay division um and the new buildings have we figured there are two ways we can achieve a high DVR Technologies one with the single applications community [Music] the second way is by increasing the total flow because and for this we don't what we compare is the two entrepreneur foreign so from this results there are two ways commonly to achieve the ipvr and within the main difference between a type of filter and annotation technology or activities about the second depend with them it will increase in the total flow of the airplane that we need to have achieved our internal total energy because we can increase the fan power but we cannot increase for Survivor by the side of the reason of leaders automatically foreign [Music] but this whole figure so the reduction compound we've been selecting it means um any kind of person but it had generated from cardboard and a positive reduction when most of the airplane from the tolerance but really about the 18 results and the fact is a loss of absorption media like the active coverage so it had achieved approximately which numbers significance um [Music] performance [Music] received so comparisons the rumors uh inspector which is significant introduction of the other uses and there are only two but the certain more normal performance but they typically uncertainty chapter method animation about measure earthquakes [Music] environment foreign um and the second kind of developing more information about this correlation so here it's a summary so we propose the immediate the network and the product change uh under the foundation and we do the through the parking their winners of information they have the same momentum 2.5 foreign [Music] so here is all of my translation and the sense for our destination so it's a pure infection or any questions first and I will move to the maximum region after all students so on your last slide we showed that the 90 removal of 99 [Music] Muslim so how did you separate whether they were inactivated or removed oh yes this was covered in the second presentation yeah [Music] basically two questions [Music] user [Music] [Music] foreign [Music] [Music] [Music] values [Music] during the testing period before the evaluated at single Constitution in order to get back to the numbers whether it's made with machine conditions name are your question is very important so if you want to address the Real Environment when we review uh that's another modeling uh in terms of space uh Revolution that's your second question the first question about the itself know about the surveys right right according to the last one again it requires another model right so the chamber tests showed the unique and performance and then you take a mod as you even one of the parts of the International International agency IA 10x078 button that will be contribute in the modeling through with my services but how much sovereign [Music] thank you any questions I'm just curious about the models I can understand that one published brand names yeah sort of a question I think that well uh we don't want to sort of minimize the commercials [Music] [Music] let's see foreign foreign yeah I think that we we don't get into the component so I need to say a caution to be a little careful with that if the word happens so it doesn't necessarily mean the same thing right unfortunately um thank you I think it is here the main object is thanks okay so I think we should move to the next question in the chat any questions [Music] okay yeah let us know the question from that great question and also introduce another coach AI about this project the professor again is foreign in 2018 [Music] so that was impressed by a student and gave me a really nice card there turned out to be a junior and anniversary from Pittsburgh so I had a chance to talk to her because imagine there was my employment um so I was really happy that she applied to us and we were to report her to develop this diploma and so after she started at that maintained and they start to think about the virus to heaven so my lab in working with the microbes since I've been doing 2006 so primarily um I didn't realize about what federal studies but Jason imagines so when there's a Verizon came in 2011 virus we still have ideas and then since then she had an important to the program I want to work on those viral transmission foreign [Music] years so my colleague Samuel um he's done a great job in presenting the results for the direct linear performance sort of reveal scenes and aerosol particles in there without being zooming in more on the various performance of insane air conditioning power all right so here I here I am showing an overview of the work that we conducted so what's the virus aspect of this project and so we started out by evaluating the um something methods for the virus in the air and also establishing remote sampling methods for environment services and then we took this something Microsoft would established as well as our development normal test method so assess the first question advocacy of the various reference economies and then we also did some validation of work so basically assess how well this virus is being distributed within version we received a question from the last presentation regarding the wellness nature of this aerobiology um chamber of our news um so I'll be shedding some more lights on the on how the virus was basically distributed within this um and then we also answered some interesting research questions um looking at the correlation to the particle concentration on the viral world as well as how the virus interacts with on different surfaces so many more remembrancies and also looking at the virus and receive your scenes or an interaction as you know in the field of indirect quality um vocs are very important um aspect of the Uber area environment So reading new spy six as a coronavirus survey public school and so don't be scared um it's interesting virus so it's a very structural instruments they are both spherical and they don't have an arm in genome and they both have similar spine proteins that cause infection and so five six verse at the top it's a virus that begins and this virus is known in the ridiculous impact on bacteria and so the bacteria impact in the automated plans part of them foreign so here I showed that using our test method we actually found that the airplane technology specifically reduced environment and error um but we wanted to know a lot and so if we logically the right of ours at the in the absence of the earth while the darker guards and the presence of the earth now we see that um we do have sufficient reduction in the parallel and at the bottom left here I'll show the an overview of this test method just started image so it's we would in general requirements for about five hours in the absence of the air cleaner and then we would sample the virus in air for one hour we will turn on the device and then we let that run for another five hours and then we sample the air to basically determine the efficacy of the um the air coming technology so it's removing the virus in there and so those are the results we've seen um yeah and we also wanted to explore um something slightly different from the original design whereby the liquids this um this method by turning on the device from the startup injection and then we sample the air and then we turn off the device and let me sample the air and so we call that a sort of flipped methodox we found that with that other design we are actually able to capture about two loss reduction in the mirror so now in the world of viruses you have total viral particles and then within the total particles you have a portion that are infectious and so what we show here is the Quantified infectious virus um basically showed how well the airplane Technologies are able to and so we wanted to also answer a sort of a small research question using the same air cleaning technology with its newly capability turned off versus capability to turn on and we found something interesting that we we have additional singles reduction in the Infectious virus um for the same device when it's even being capacity which turned around and then we also establish an interesting correlation between the aerosol particle concentration on the viral world so starting with the um the the upper right quadrant this is basically we could look at this as a very high contamination of various particles of air versus when we turn on the lymph nodes we see that it drinks towards the lower level Quantum and overall we see that for a water production in the viral Road there's a corresponding one local milkshake it's an aerosol particle concentration and we are basically Now using this as a tool for groups who probably could not reports quantify or go into the hassle rather than qualifying the virus of air if the only use of PM 2.5 they could actually also make a sort of a correlation for what they would expect for the same device in terms of using the virus concentration there and then as quality control um we quantify the Royal genome copies the viral particles basically that are touched on another aerosol particle and for this test considering the fact that the size of the virus we're working with it's a hundred nanometer approximately and the size of the particle the aerosol particle is in one micron so we see that the virus radicals are 10 times smaller than the aerosol particles so we would actually expect that to have one various particle the aerosol particle and so we do see that across a test that we performed for the studies we had I believe stored by respirable attached on an American particle so now we looked over the various results but I want to give you back updates on how some optimization work that we did so what developing this testamental so it's basically start with how we um the method that we use for sampling the the aerosolized virus 11.5 9 meters per minute so it's all the way down to four um because we wanted to identify an effective sampling flow rate for capturing the aerosolized spices in there and so we found that with higher flow rates we are actually able to capture more virus particles however the impactivity of the from the different florals tester is essentially the same so we we decided because we want to capture more virus particles that are aerosolized we decided to use the highest stories within this design and so on the right here we're also showing the aerosol particle concentrations there's a picture of the sales distribution that means unpack for this session double large in something aerosol because of the diversity for aerosols are essentially less than 5 microns and then so that's for something that requires that we are also like however we also want to be able to expect something quantify the virus that's also the positive surfaces so we need to optimize our surface sampling methods and so the reasoning methods that we were investigating towards the study using on swabs and so the the EPA and CDC typically recommend using swaps sample viruses from the surfaces so that's why we use syrups and if we're looking for it was also found that polyester slots that they cover non-envelopes Anderson virus about by 40 retaining 40 percent of activity so we want to basically explore and release something in methods towards something invitations for this learning and due to the the sounding limitations of soybean we also wanted to compare those results against the the polyester contests which are not we should simply capture what's the social foreign [Music] experiment and then we will recover all of the tires that we supported on the list and maybe have to quantify um the overall performance of the example so from the results we see that across between something Microsoft used we were able to recover the same total virus particles as punctual however with the polyester swap we found the loss of support loss of infectivity and so that that was um we really significant so we found from this data that we couldn't use the polyester swabs for this virus although it was fine Forever This virus and so in our studies assess the well-mixed foundation in our aerobality flavor we use a cotton swab on the polyester form groups foreign so now moving on to the world makes looking more into the well-known environments within this chamber um I'm showing data about the virus distribution with entertainment and so to achieved this um we use the same um circuit to place the same surface across the randomized locations within the chamber and then we quantify the virus particles that were deposited on onto this service and so we see from the results that within two methods the cotton soft and the polyester so important is assembly methods that we explore we actually had the same viral mode um distributed across the different locations that we meet and within this chamber so this was essentially a validation for us in terms of um looking into the well-runixed nature of this environment for the virus um and then um so many more on the colleague herself on this we found that um whenever we had an increase of virus concentration in the air so this is about log six and going all the way to work seven we have a corresponding um increase members that were deposited on this as we had up to so going from um Log 5 on photograph on the left and see um that there's a higher load on the graph on the right and so the lower bound we established using the polyester from this so the download File versus the upper boundary mode six and we compare this with what we achieved for um using the cotton swabs to sample the virus on the download deposited on the randomized equations and we found that the lower bound with the possible versus the upper bound being log six and so we see that the the the with the lower boundary mode four um that's not most likely due to the um the sampling limitations for this method because you the the this basically quantify everything that wasn't positive has a higher um foreign [Music] so we did an experiment where we only injected virus to this um 30 cubic meter um chamber and then we also in the same room on the same conditions it then also injected on the vocs alongside the virus and from our data we found that there wasn't any significant um impact on the variable or the impactivity of the virus particles so essentially cblcs at space levels being being parts per billion didn't have a significant impact on the impactivity however we wanted to look more into a possible threshold concentrations um that would actually cause a compromise of the infectivity of the virus and we found that so we took the the Turning parts for premium concentration in there and found the corresponding concentration and liquidity partition coefficients and we start found that at ppv levels there's no impact on infectivity however when we go all the way up surprise that million on Post locations we can actually lose about three lots of infectivity however we also want to know that business for expensive purposes although we didn't use Harvest concentrations for the studies that we're probably looking for the American Concepts so so far for the VOC we've looked at the way it makes you lots of viruses in air but we wanted to zooming more on early um interactive advice that's unsurfaced it and so for these experiments we injected the virus only and then we also we have the these um sorry this these common services within a chamber and then we would inject only virus and then we would inject the virus and the and obviously on a separate in a separate experiment and so overall for the results we found that there wasn't any significant impact on the Intensive nature of the virus um and PPP levels for the virus will be deposited on surfaces but interestingly we found that um for a surface that's been coated with these things are content citation and dioxide um you could actually completely um means the Intensive nature of the virus and physics commonly been used in a lot of the things we have an antiviral nature to improving your air quality and then we wanted to look at how the vocs would impact on the virus load that's been positive on surfaces so the great bars is basically just having the reverse only and then the green the lighter green guards is a viral load with now with the amuse injection and we found that there was any significant impact on the variable that's being deposited on surfaces in the presence or on the or DLCs so so far we talked about the results we had from the airplane Technologies we've also looked at the optimization of our sampling methods we've looked at the VOC interactions and so now we wanted to also look into the style of how different surface properties would impact the various survival so for the before we did any of these um air cleaning um tests we would prepare the virus saw and we would also sterilize that stock by plastic in through filtration membranes to have it very very thorough and so what we found is that for the membrane exam we evaluated I think we can with examples nylon membrane and mixer plus Ester we could recover sufficient virus particles when after being passive through these membranes however we did find that um the nylon membrane and this is a positively charged membrane and the mixed cell was as well as a negative charge membrane and with this we actually completely lost the impact signature first so when you're not to use on the latter two numbers for these tests and so for the treatment test we only use the calculator service membrane so let's prepare ourselves that we would inject to conduct new service so we sought assessing the world mixed nature of these experiments we wanted to better understand how the virus actually would behave when it encounters um these common touch surfaces that are that are common in the build environment and so we looked at the survival on non-porous services and then we also look at the survival on for our services and we found that overall when the virus encounters not for our services being service and certain speed boards stainless steel glass um the inflativity wasn't compromised however we found that when it encounters porous services so Services essentially you could think about this as having a very high monster absorption capability compared to the non-polar surface we found that we actually lost in one to four a lot whenever the virus and encountered these services and even more on recent um in our most recent included research project we actually found out this was as a loss in creativity was as a result of the destruction in the local community Within These materials and then similarly so we also looked at how the virus behaves on holding our services and for the impactivity was just as fine similar to how it was on the non-powered services so in conclusion I'm using our test method that we developed we're actually able to say effectively um quantify the performance of everything as to what is this an infectious virus by at least one more portable parameters and then we also recommend the service center methods of big pots and swaps and we also found that the viability of the virus is significantly influenced by the service properties um the the gross major of the services that actually impact infection disruption in the local humidity and we also found out electrostatic interactions when the virus encounters charge on materials such as the nylon cells I served um compromise and we also found that titanium website um it's a it's a very strong antiviral clinical agent and we found that huge levels of PPD levels of formaldehydrates we have no adverse effect on the viral load and intensivity and air or what environmental services and we were also able to establish a strong correlation between the viral loading air and the aerosol particle concentration as those cell within a clusters from our data thank you questions [Music] how long the viral load Run for the new air cleaner or not first it was the same time frame is when it was whether it be revealed good question so we the virus is constantly injected I think I also mentioning that it's constantly injected throughout the duration of the study okay but initially you turn it on for five hours turn it off and also uh thank you hey this is uh Bud Offerman Colin and I I just curious what uh the vehicle was for your um your generation of um aerosols what what fluid you're using oh so the the media it's CSV media okay so here's the thing um maybe you could speak to this it has to do with shielding so people in UV kind of know about shielding that pathogens when you're trying to inactivate them with additive agents like UV or ions or whatever um the expired uh respiratory droplets uh are um are are in uh respiratory fluids that contain a lot of salts and stuff and they dry really quickly and the virions are contained inside these particles so the smaller particle you test let's say I think you said one or two microns in diameter are easier to inactivate than larger let's say five or ten micrometer size particles again with dried respiratory fluids so I think that's something for both the air tests and for the surface test yes that you address something that's kind of more real life and that you'd be using simulated respiratory fluids and ideally it's the larger size ones you want to be able to demonstrate that you can inactivate because those are the most difficult ones so I just thought I'd like to hear your thoughts on that I see for sure [Music] um I I think they'll be another research question because the focus more of the work that we performed was aerosolizing the virus and basically focusing more on aerosols but we know when we took care of that the droplets of the largest of five microns so I think that would be uh potentially new or a separate research question that we've been um yeah it's probably just a good caveat to have that um there's definitely demonstrated a lot of uh uh um viral load in particles that are you know three four five six seven microns in size and that your tests might um the the the the effect of this that you might see on these larger particles maybe less foreign so uh James grieve on the phone uh can you hear me yeah so my question is during the pandemic I understand a number of buildings went to 100 outside air uh is is filtration equally effective for uh virus mitigation and oh and what's the Energy Efficiency difference outside air versus filtration fine it was a well-ventilated environment because we wanted to simulate the most realistic condition as possible that's right um [Music] standard which is associated with the law area and the University um and that is about Point balance [Music] leader uh which is when people at least three months especially uh and uh associated with the basically developers virus in terms of time power we are using and others so but in general uh and it is from the current results [Music] foreign [Music] yeah not a question a couple questions is there any alternative for a more accurate test um we we started it how to be some level of accuracy um because when I showed the lower amount I think I'm not sure but it took me a while but anyway so I showed the um okay so I showed the lower and upper Bound for the environmental constipation so essentially the total virus particles are deposited for area and from the swabbing method we we found that the lower value is low core which is lower than what we would have when um we just use the discs which is a limited by human um sampling so even though the swabbing method um could still recover the same upper amount of 10 to the sixth however the lower bound was times before so we hypothesized that that's probably due to human sampling limitations um but considering the fact that both something methods have the same proper amount of times the six so we see that it's still decently accurate because it's the um the recommended um something something method by APA and CDC for something various particles from services so it was still important we use that same sign of apprentices yeah yeah today I mean the other question is it seems that all of your research which is bringing the features um this is mostly focused on Portables Matthew everybody [Music] different programs even anonymous so just one yeah the one point a lot of the swabs we did incredible pastors have cognitivity they're targeted positive and negative he was not unbelievable so you can get rid of the confidence [Music] that's where everyone want to see more everything and assembling this is [Music] maximum [Music] uh yeah so um smart controls um so we talk a lot about the important virus so what I'm trying to do here is to try to balance the image and a house a lot of times we know that when we put 10 our air into the Space Systems so how we can balance the inner function of students and the relationships Meister instructions done it so let's welcome more foreign [Music] degrees [Music] [Music] and uh about such a large limit usage file or or seven percent organized and out of all the reasons for such a lovelyness what research has indicated as a one of the rivers is due to about religion so if we want to address the evaluation it's not available [Music] performance [Music] there are some real solution parameters environments for example in the whole summer the United government will be integrated by all our conditional improvements advances and arguments all the weather will increase the temperature and Equipment devices and Outlets who are not only the fact that the temperatures are also a part of the north records so to improve the indoors on the digital system so it is a natural growth to Simply break under control resistance matters well the process is that so there is no control serving comparing all of that as I were mentioned so there are two complicated in the business answer why is certain independency and another is another order the cool influence of vastness will always build an order so the simple question is that can we develop an intelligent controls value to better balance people whether than the IEP patterns looking to volunteer about the framework the two projects we developed the two types of neural network models the first day is field space Department in our world and another is the larger conglomerate new network these are used to produce Dynamics and although other conditions please download creative models with the developed the hierarchical and to give you control to optimize for electric usage level [Music] so for our forward uh canopying work we use the uh the office with the foreign [Music] models uh the most important model is the one to prediction and we developed the Olympics and inform the neural world and before I show the performance of the things of using business and also the combinations of some of the resistance and the compartments is your name for students because it's building itself and externally a Samsung model has limited the Model Behavior because it's typically a linear model and a candle has to reduce so the group of smaller is not a spillable model and your surgery developer based on such model is cannot be implemented on your large scale and to address the stability issue of the black box because it's an impressive expert piece to be valuable but it also has some problems first of all the likes the ability for clinical unit probability for the Model Behavior because our listening because we don't know what happens in each other with the Xbox so we cannot guarantee you or if the model can give us algorithm response to internal control signals and also uh so little Global model that's the guarantee of the lower Optimum for optional control so some modifications are needed for the drivers model if we want we want to use a substance on the model and uh therefore in our research we developed a normal pigs informed and neural network to combine the advantage of two types of the model and also adjust the dispatch simulation here we compare the of the model performance between our business neural network and this is the model or an indoor temperature and coming outside competition for these were on the real slides for both tradition locates the importance that is the model and besides the more the prediction accuracy we also tested the model response was different although the results of the art so the basically important you know how to work had a similar response as the things that is the model so after the developments of the indoor Dynamic operating model another importance of traditional models is to forecast the shorter uh local weather so people may wonder why bothering to develop such a model because there are a lot of whatever kind of services online and here are the reasons the surveys online we will find that the highest pocket frequency from the website that is our foreign so some people would use the forecast because it is also the TalkBack if we look at the weather forecaster for the front of airports and the officer for service University business so the weather forecaster at uh airport is now representative enough for the weather and circuit University and we simply use the forecast around the airports the control performance and a lot the last reason is the solar division is one of the new version factors for the indoor Environmental Quality so it's a sewer forecast solar focal Services is not hardly available online So based on this readers in the in our research we developed our own weather forecast model to predict the other air temperature and the solar division is [Music] just so it's really our model based on the Arts structure and use the tool here from Southern University and here it shows the similarly order temperature forecast and here we compare the results and we can and we can see here there's almost no difference between predictive or temperature and the metal temperature the arrow is the only final six percent and the answer for the solar engineer podcast the little means where arrow is the only 76 volt square meter which is also accurate and based on our best knowledge our solar religion workers model all of one is the most models in research literature and besides the single day forecast away also cut the model for continuous and the hero which which shows the prediction distribution or developed steps comparing with the distribution of food Dynamics which is the average part the distribution of the prediction is almost the same as the amount of distribution which indicates in your very high accuracy of our work and similarly for the summer reading broadcasting the similar Behavior which also have a very high accuracy so now we have role models to predict the indoor environmental Dynamics and the influencing factors are very accurately and the next step is to development requirements [Music] so we uh we tested our address during the simulation case for one hour here use the statistics for the Illinois Environmental Quality and uh you know figure the red color rather than the amount of data and the large colors rather than the simulation heaters and we have two simulation cases one is with 100 percentage of weather information another is using our available customer model hello here it looks a lot are the requirements of all the Environmental Quality and the component with this is no air temperature and coming outside concentration as for another aspect which is energy usage so uh combined with the management of the earth and the average relation is seven percent so from the um level and if we compare it or the energy usage [Music] there's almost no difference due to our accurate water forecast so uh are the four are the foreign [Music] so at the conclusion of our research study we developed we have developedics at the moments and the model all performs in the fixed business model always the physics the consignment behavior and our our team another world uh very accurate the controller is the weather forecast and based on the uh pretty easy models our actual the ultimately we control striving probably the significance and as our future work we will Implement our Advanced recognition work from the password on an Encompass to the customers and we will also incorporate the outcome of the coordinator one to our control and Central and I appreciate the auctions [Music] foreign [Music] opportunities [Music] certainly I don't understand that there's a correlation between the 2.5 and viral lowers if you knew the 2.5 exterior and the 2.5 interior could then become a control mechanism for turning
on their limiting capability definitely you know if it's not needed then save the energy right but they've built levels put out of balance there are more things to be controlled oh that's a great question so so that is one of our future workers experience [Music] fair question I'm not sure if you're familiar I've been working in a dealership in our country probably I wrote that was a few minutes and uh they could do a lot of what this message um well what about the conditions [Music] but anyways if you don't know about good weather but sorry yes so now in this project in another project we look at two weather forecasting materials so one is for ideal I didn't have very accurate weather and also two two relevance company so we actually developed another algorithm which already five items there so it's much more accurate than IBM wizard so it's more sensitive effect but not on this product but I'm very I'm very open to talk to True wizard see how you know what's the break they have so my algorithm is more fun way so we don't want to do that by the way into the building foreign [Music] so bringing localize the day of collector where it seemed to be a a good tool to do we continue to predict that we know where it is we know what's coming we know what's happening six buildings down and then so you know we know what it's coming hopefully in enough time that the building's been adjusted for what's about to do newspaper we've just got another one of the top 10 cities for Holland in the country did you see that uh [Music] so we'll have to distributed senses any other questions for um outdoor air quality and how many times so is there any way to make up for example in bad air quality outside we don't have them inside can depends on another who's outside uh increase your airflow into the mouth uh so I assume you're awesome I'm not understanding exactly what your medicine is more responsibility of the CEO or what do you think of my question is essentially yeah they uh we have so well how do I add a product we would have to imagine those pollutants so you have PM 2.5 you have no knocks ozone for those types of imaginations actually looking at the product uh integrating that information and uh based on management uh whatever considered under Africa [Music] that's a Commanders okay um foreign [Music] foreign that's what density does yes because our subject to review later will come out there are papers to publish the papers for example yeah yeah [Music] movement okay is that out that's science speaker one more time so I think we we before we get into we still have another activity which is a tool so we have a new lab you really don't have quality levels building buildings under Science and Technology as well and uh positive people on the web we do have a research day work depending technology in April we have another I.T model and digitally focused on Urban Music so a lot of ideas distributive centers how do we produce as information to understand why and then the second assumes that you made of that through those presentations to uh in that research thing we're going to a highlight the teachers are important like a large project for example and uh relationships and Technologies and we have a couple of continents subscribe to us and I just got this this is very interesting talk to her exposed faculties and um to both research and a lot of research and that also in the grouping them to us um it was was that I thank you again for coming to this seminar I think it's very interesting about our free discussions but there's some professionals outside would help yourself and do those are networking uh as the lab to work that is thank you
