umbrella of Urban Heat Island (UHI) and I am going to try to separate them out in order to give you a sense of the current capabilities in LB+HB.
1) UHI as defined as a recorded elevated air temperature in an urban area:
If you have access to epw files for both an urban area and a rural area, you can use Ladybug to visualize and deeply explore the differences between the two weather files. Ladybug is primarily a tool for weather file visualization and analysis and it can be very helpful for understanding the consequences of UHI on strategies for buildings or on comfort. This said, if you do not have both rural and urban recorded weather data or you want to generate your own weather files based on criteria about urban areas (as it sounds like you want to do), this definition might not be so helpful.
2) UHI defined by air elevated air temperature but viewed as a computer model-able phenomenon resulting primarily from urban canyon geometry, building materials, and (to a lesser degree) anthropogenic heat:
This definition seems to fit more with they type of thing that you are looking for but it is unfortunately very difficult and computationally intensive such that we do not currently have anything within Ladybug to do this right now. I can say that the state-of-the art for this type of modeling is an application called Town Energy Budget (TEB) and this is what all of the advanced UHI researches that I know use (http://www.cnrm.meteo.fr/surfex/spip.php?article7). Unfortunately for those trying to use it in professional practice, it can take a while to get comfortable with it and it currently runs exclusively on Linux (this does mean that it is open source, though, and that you can really get deep into the assumptions of the model). A couple years ago, a peer of mine translated almost all of TEB into Matlab language making it possible to run it on Windows if you have Matlab. He wrapped everything together into a tool called the Urban Weather Generator (UWG), which can take an epw file of a rural area and warp it to an urban area based on inputs that you give of building height, materials, vegetation, anthropogenic heat, etc. I would recommend looking into this for your project, although, bear in mind that is it not open source like the original TEB tool and that you may need to get a (very expensive) copy of MATLAB (http://urbanmicroclimate.scripts.mit.edu/uwg.php).
3) UHI as defined by a thermal satellite image of an urban area depicting an elevated average radiant environment that reaches a maximum a the city center and changes by land use:
This is the definition of UHI that I am most familiar with and was the basis of much of my past research. I feel that it is also a definition of UHI that is a bit more in line with where a lot of contemporary UHI research is headed, which is away from the notion of UHI as a macro-scale meteorological phenomena that is averaged as an air temperature over a huge area towards one that accepts that different land uses have different microclimates and (importantly) different radiant environments. While the air temperature difference between urban and rural areas usually does not change more than 1-4 C, the radiant environment can be very different (on the order of 10-15 C differences). The best way to understand UHI in this context is with Thermal satellite images, for which there is ha huge database of publicly available data on NASA's glovis website (http://glovis.usgs.gov/) or their ECHO website (http://reverb.echo.nasa.gov/reverb/#utf8=%E2%9C%93&spatial_map=satellite&spatial_type=rectangle). I tend to use thermal data from LANDSAT 5-8 and ASTER satellites in my research. Unfortunately, there is a lot f bad data with a lot of cloud cover mixed in with the really good stuff and it can take some time to find good images. Also, there aren't too many programs that read the GeoTiff file format that you download the data as. I know that ArcGIS will read it, a program called ENVI will read it (I think that the open source QGIS can also red it). I have plans to write a set of components to bring this type of data into Rhino and GH (I may get to it a few months down the line).
4) UHI as a computer model-able notion of "Urban Microclimate" with consideration of local differences and the local radiant environment:
This is where a lot of my research has lead and, thankfully, is an area that Honeybee can help you out a lot with. EnergyPlus simulations can output information on outside building surface temperatures and these can be very helpful in helping get a sense of the radiant environment around individual buildings. Right now, I am focusing just on using this data to fully model the indoor environments of buildings as you see in this video:
https://www.youtube.com/watch?v=fNylb42FPIc&list=UUc6HWbF4UtdKdjbZ2tvwiCQ
I have plans to move this methodology to the outdoors once I complete this initial application to the indoors. For now, you can use the "Surface result reader" and the "color surfaces based on EP result" components to get a sense of variation in the outside temperature of your buildings.
I hope that this helped,

ce issue with Rhino and shouldn't make an issue with EnergyPlus but just to have cleaner geometries, I untrimmed base surfaces so zones are closed brep now.
I also noticed that when you are adding multiple openings to a surface, the surface doesn't show-up in the output of createHBZoneFromHBSurfaces. The surfaces are there though and show up once you explode the zone! Again should be a tolerance issue for join. I need to take a closer look to both of these.
Also, in a number of the zones you had wall surfaces connected to createZoneFromHBSurfaces both before and after adding glazing. I removed parent surfaces so you don't end up having duplicate surfaces.
Back to adjacency which was your question, the issue happens since you have couple of zones with the same name so component was assuming them to be the same zone so it wouldn't solve the adjacency (Yes! it shouldn't. That was a bug which is fixed now). I changed the names and now it should find the surfaces that you are looking for.
Moreover, once you solve the adjacency, next solveAdjacency won't overwrite the BC unless you set remCurrentAdj to True.

he concept, moving on to decision making and continuing with digital and generative design tools TO GET THE BEST SOLUTION for each problem.
WHY? The world is complex and ever-changing and we need to be able to handle the volume of information we receive and, of course, to find and choose the best solution. Therefore, we direct our ATTENTION TO THE CAUSE, and not only on the effects/solutions.
We will learn from NATURE, the only “company” that has not gone bankrupt in over 4000M years, and it’s GENERATIVE SOLUTIONS.
> OBJECTIVES <
The participants will work in multidisciplinary groups (ex. architect + designer + business manager + constructor + communication specialist etc.) applying knowledge management tools, different approaches and nature-based optimization methods.
Listed objectives:
1. Improving the generative way of TURNING AN IDEA INTO A PROJECT through problem-solving thinking
2. Discovering nature’s ways of shaping evolutionary solutions
3. Getting out from our comfort zone and working together with other professionals in groups in order to achieve better solutions: Multidisciplinary Design Optimization
4. Learning to use technology to manage information in the decision making process

f my list.I don't understand why, but I guess I must be too young user ^^In the original list, i have a path {0;0;0;4} with two index and after the random node, {0;0;0;4} has 88 index.Items are not correct?I would have a comparable structure has the right list on my jpg (photomontage...)How I can do that?Thank you in advance

nputs to run (please refer to the image)
Currently, here is how I set the data:
protected override void RegisterInputParams(GH_Component.GH_InputParamManager pManager) { //Create default size
double defaultBaySize = 0; pManager.AddTextParameter("LotLib", "Llib", "Lot Library", GH_ParamAccess.tree); pManager.AddCurveParameter("BoundaryCrv", "BC", "Boundary Input", GH_ParamAccess.list); pManager.AddIntegerParameter("Direction", "D", "Direction of gridLines", GH_ParamAccess.item, 0); pManager.AddNumberParameter("CCsize", "S", "Distance from column to column", GH_ParamAccess.item, defaultBaySize); pManager.AddCurveParameter("GridCrv", "GC", "Take in curves input for gridlines", GH_ParamAccess.list);
}
protected override void SolveInstance(IGH_DataAccess DA) {/* Setup */ GH_Structure<GH_String> LotLib = new GH_Structure<GH_String>(); DA.GetDataTree(0, out LotLib); List<Curve> BoundaryCrv = new List<Curve>(); if(!DA.GetDataList(1, BoundaryCrv)) { return; } int Direction = 0; DA.GetData(2, ref Direction); double CCsize = 0; DA.GetData(3, ref CCsize);
List<Curve> GridCrvs = new List<Curve>(); DA.GetDataList(4, GridCrvs); if (!DA.GetDataList(4, GridCrvs)) { return; }}
Is there a way can set data in the way if the component does not receive inputs for BoundaryCrv but only GridCrvs, the BoundaryCrv List will empty.
Thank you very much …
