The display attribute node (displays the scale bar) in the phtj_utils.otl hase had some bugs fixed.

Competition
I will be busy until 2.20pm, so please make a start and analyse the information on the Vertical Cities Asia website.
Houdini license server restarted
I just checked with Sek. It seems that the license server crashed over the weekend - not sure why. Sek has restarted it this morning, and Houdini should be working again now.
phtj_utils
I have added one more node to phtj_utils. This node allows you to display any numeric attribute, and also generates a colour bar. The zip file contains an example of using the new node.
The node was originally developed by Zhang Ji at CSAC, NUS. I have changed a few bits and pieces here an there.

Houdini help
I just saw some great new help documents (PDF files) for Houdini, on the sidefx website:
Vertical Cities Asia
For the studio, we will be using the Vertical Cities Asia competition as a vehicle for IVP.
On Monday will be the presentations for assignment 2 of the elective. However, I have just found out that there will also be a briefing for the Vertical Cities Asia competition, at 3pm on Monday, in the urban design studio.
So we will have to move the presentations forwards a bit:

EnergyPlus V2.3
Another bug fix:
- shades were being assigned to the wrong surfaces

EnergyPlus V2.2
Some more bug fixes for the energy plus nodes:
- windows were being assigned to the wrong surfaces
- the data folder generated an error when the name was changed
phtj_shapely
I have uploaded the shapely node, originally created by Kian Wee Chen. Here it is:
There are a few files and folders in the zip.
The phtj_shapely.otl needs to be copied to your otls directory
The shapely folder (including the folder itself) needs to be copied to:
...\Houdini 11.0.xxx\python26\lib\site-packages
There are two geo folders, one for 32 bit windows, and another for 64 bit windows. Choose the folder for your version of windows, and copy the files in that folder to
...\Houdini 11.0.xxx\python26\dlls

EnergyPlus V2.1
I have fixed a few bugs in the energy plus nodes. Now you can create attributes for more than 3 zones (50 max). And you can get heating and cooling for zones. And I simplified some of the naming of the attributes.
You can use the same download link as before - phtj_energyplus.zip
Note that I have not yet fixed the boundary bug - if you are doing floating zones, you still need to select both 'Roof boundary is floor' and 'Floor boundary is roof'.

EnergyPlus V2
The new version of the energy plus nodes are here! It has some more friendly nodes for creating attributes required for the energy plus simulation. Also, the energyplus_link node now allows you to specify internal gains, and also link floors and roofs (as discussed at the end of monday).
Like last time, there are a few files and folders in the zip.
The phtj_energyplus.otl needs to be copied to your otls directory
The py2energyplus folder need to be copied to:
...\Houdini 11.0.504\python26\lib\site-packages
The base.idf and the test.hip can be anywhere, but must be together in the same folder.
Do not save anything in folder with spaces e.g. "My Documents"

EnergyPlus V1
After some delay (it is already nearly 3pm!), here is the EnergyPlus node. I was trying to fix a bug - I have half fixed it, but I will do another update tomorrow. For the meantime, we can get started with this one:
There are a few files and folders in the zip.

phtj_chops
Here is the chops otl file. Also, the phtj_utils otl has been updated - a few bugs have been fixed.
Elective (AR5953a) Assignment 2
Assignment 2 for the elective (A5953a) is due in Monday 14th Feb. You will be asked to prepare a 15 minute presentation, using slides and video captures of Houdini. You need to create an A3 landscape booklet documenting your presentation. The assignment is worth 50% of the grade for the elective.
Some other links:
- The site is a large block (175m x 185m) based on a site in Marina Bay area. Please see the houdini file for more details. An abstract model of surrounding buildings has been generated using the densities from the URA 2008 plan.
- The task is to develop a proposal for a mixed-use urban morphology that is high density and that also provides good quality of life.
- Mixed-use in this case means office, residential, and commercial. The number of people working in the building should be equal to the number of people living in it.
- High density means an overall plot ratio of 13 (i.e. 420,000 sq meters). This is the plot ratio that has been set by the URA. Car parking should also be considered, and is not included in the area calculations.
- Good quality of life means thinking about various issues that make life enjoyable. These will include daylight, ventilation, views, privacy, open spaces, noise, etc. The importance of these issues will be different for residential, commercial , and office.
