Some New Solar Articles 16 Apr, 2019
Whilst writing some new documentation for my solar analysis API classes, I kept adding way too much background information, making them far too long to actually read. At that point I knew I had to separate that stuff out, so decided to add them as a series of articles on PerformativeDesign.com.
Sky Distribution Equations 18 Dec, 2018
A number of people have asked me for more information about a comment I made in the CIE Sky app description about using the "latest" sky distribution equations. Basically, whilst trying to work out why the numbers I was getting from my implementation of the CIE Standard General Sky were slightly different to those from other popular daylight tools, I noticed that all of them appeared to be based on code that implemented the original Perez All-Weather Sky equations published in 1993, rather than the CIE Standard General Sky equations from 2003. The differences between the two are relatively small, but certainly enough to confound any direct numerical comparison.
New Schedule Editor 09 Jun, 2018
I have finally finished my online annual hourly schedule editor, which took several iterations and quite some time to get working the way I wanted. It's of interest because hopefully its relatively easy to use and can read and write schedules in a range of different formats, including EnergyPlus (IDF and epJSON), OpenStudio (OSM), DIVA/DaySim (.OCC.CSV) and some other CSV layouts.
Why Educational Tools 12 Nov, 2017
A common question I get, both directly and indirectly, is why do I spend so much time on what seem to be pretty limited educational apps rather than doing a full-on building analysis tool that can handle real projects. I documented this at the start of a recent research paper , but figured that I should probably summarise my reasons here as well.
BIM and NatHERS Headaches 21 Nov, 2015
Given that my blog doesn't get updated much and there is no other obvious output, lots of people ask me what exactly I am working on at the moment and why it seems to be taking forever. Usually I just mutter the odd platitude, but today I thought I would combine a bit of a rant with an actual example of the kind of problems I am currently and seemingly constantly wrestling with. This one involves the ideal of determining NatHERS compliance directly from a fully integrated building information model (BIM).
ACADIA 2009 Workshop 20 Sep, 2009
I will be presenting a research workshop at the ACADIA 2009 conference in Chicago on the 20th-21st of October 2009, to be held at the School of the Art Institute of Chicago (SAIC). The aim of this workshop is explore the boundaries of generative and performative design using Autodesk Ecotect Analysis, Green Building Studio and Revit.
Master Class in Berlin 07 Sep, 2009
I will be presenting a master class at the Design Modelling Symposium in Berlin on the 5th-8th of October, 2009 at the Universität der Künste. This will cover the use of BIM data for a range of different types of performance analysis and the best ways to convert and transfer what you need.
BS2009 Workshop 18 Jun, 2009
I will be presenting a 1-day workshop at the Building Simulation 2009 conference in Glasgow on Friday the 31st of July, 2009. This will cover the use of BIM data for a range of different types of performance analysis and the best ways to convert and transfer what you need.
