We are developing a real time web based energy simulation program that can 
be used in the early stages of a building design to easily and rapidly 
assess the impact of major design decisions.

A beta version is freely available as a real-time simulator on the web at 
:  DesignAdvisor at mit.edu

The program requires a PC with Internet Explorer or Firefox

The web suite of building energy simulators that model energy, comfort, and 
daylighting performance, and give estimates of the long-term cost of 
utilities. The simulations restrict flexibility in order to offer users 
greater ease-of-use and speed. The tool can be quickly mastered by 
non-technical designers, and runs fast enough to allow them the scope to 
experiment with many different versions of a design during a single 
sitting. The immediate feedback that the site provides makes it useful in 
the conceptual phase of design, when architects cannot afford to invest 
large amounts of time to rule out any particular idea. The emphasis of the 
energy model is on the envelope system of the building, and includes 
simulations of high-technology windows such as double-skin facades. 
Energy-load estimates are based on a library of hourly climate data for 30 
different cities around the world and include transient interactions with 
thermal mass within the building.. Lighting simulations are carried out 
using a rapid radiosity calculation method. Hybrid and natural ventilation 
strategies are evaluated for energy saving and comfort conditions.
