mple, but this file creating towers of a particular volume linked to their equivalent low-rise volume where I make boxes using Bumblebee so I can build performance graphs etc in Excel should suffice.
Ultimately what I had in mind was to build an analysis tool that allowed me to explore the Simple Static Heat Losses in the spreadsheet for the design alternatives, or even to have a set of heat losses for each 5 storeys of the building height from 5 through 100 storeys - to understand heat loss, linked to Rhino/GH to plot a 3D landscape of these options. This would then be linked to HB so that I could (first) plot the solar gains on the building facades for one building in a neighbourhood of similar height, and then divide up these basic towers into bottom middle and top floor Energy Plus and Daysim analyses of a standard 5 zone division of the floor.
Failing the intelligence test, and not even being able to move from simple mesh to simple analysis in LB has the grand vision stalled at step 2!
BTW: with my (2016) version of Excel I get Excel.Interop error messages if I try to use the <Live> option for streaming the spreadsheet into Rhino/GH, so I re-read the spreadsheet manually by toggling the Boolean <Runit> option to read in the data.

onent are experiential or location specific. For example: humidex has been derived and widely used in Canada.Also both humidex and discomfort index should be used in in-shade conditions.For universal applications and locations, you should concentrate on either PET or UTCI (this is what "Outdoor Comfort Calculator" component is based on).
I have found out, that for instance - OutdoorComfortCalculator - which considers temperatures of 9-26 and other factors, gives the % of comfortable time outdoor for instance in Kenya in Africa (high temperatures and humidity) 55%, whereas within the same .epw data and some additional factors added to the Thermal Indices component, the "humidex" or "Discomfort index" give a result drastically lower, I think it was even 1-5% comfortable.How is that?
Yes, this is one of the issues that I have with UTCI index: the authors wanted to make it as an index applicable in any type of climate. To create the UTCI comfort categories a number of data has been collected from different locations (for hot humid climate, it was the data from Madagascar. I may be wrong on this). This resulted in universal comfortable range of 9 to 26 C which you mentioned. How would the people in Madagascar perceive the feel like temperature of 9 degrees as comfortable is beyond my understanding.Thermophysiology of a human in Madagascar, and in Poland is the same. However their acclimatization is quite different, which raises the issue with the upper universal comfortable range. In general people who live in hotter climates have a bit higher tolerance to high temperature than those living in continental climates. And vice-versa: their tolerance to lower temperatures is lower than the tolerance of the people from the continental climates. Here is a comparison of the UTCI - PET stress categories:
UTCI
all climates stress category
above +46 extreme heat stress+38 to +46 very strong heat stress+32 to +38 strong heat stress+26 to +32 moderate heat stress+9 to +26 no thermal stress+9 to 0 slight cold stress0 to -13 moderate cold stress-13 to -27 strong cold stress-27 to -40 very strong cold stressbelow -40 extreme cold stress

I attached below an example of PET humid climate comparison with UTCI, for in-shade and out-shade conditions.As it can be seen UTCI shows the percent of time comfortable: two times higher than PET.
Thank you Pin, for the useful comment, on usage of "Analysis period" component.…
s that setbacks are not possible to input using the thresholds component for that particular example because the OpenStudio apartment schedule doesn't have setbacks. I totally get this.
However, I get the same error for the office and classroom programs, and looking at the IDF file it's clear that both of these programs do have setbacks. In fact, I discovered this issue because I was trying to model a classroom with heating (<18 dC) but no cooling (>40 dC) and kept getting high cooling energy usage. The setback in the IDF file appears to default to 27 dC:
This probably explains why even though the max zone temp that is registering is 38 dC and my thermostat is set to 40 dC, I'm seeing a lot of cooling energy use. Is there a way of changing the setback through Honeybee?

On this page, he shared few 3D coral difinitions and especially interested in first and second one.

I followed these instructions, succeeded to build Tetgen, placed the built files in C drive directory and tried to run the definition. Then some WindowsError came out as follows which I don't know how to fix.
My working environment is;
OS is Windows 7 Ultimate 64 bit.
Rhino is version 5, 64 bit.
Grashoppper is version 0.9.0076, the latest version at this moment.
It would be great if I can have some help advice / comment.
I appreciate for your attention.

n get the correct results with cooling loads:
3. After I update LB+HB, a warning is given for the set EP construction component:
4. so I replaced it with the latest one (Feb 05, 2017):
5. Now the cooling loads is missing from the result for reason unknown ...
May I ask if the missing cooling loads is related to the latest update of LB+HB? What component update is causing this problem?
BTW, I'm using Singapore's epw file, and for a tropical city, there should be no heating energy at all. So, sth clearly is wrong over here ...
Thanks.

xcel 2016 somehow, because previously when my laptop had the excel 2005, it works.
Also would there be other ways of reading csv file in Grasshopper other than using that ReadFile component such as using VBscript component?
Just in case if it happens that the bugs are the problem.
Thank you very much again, and please let me know if it worked in yours.…
