Building Energy Simulation Workshop

Natural Ventilation and Mixed Mode Operation

Venue: Centre for Advanced Research in Building Science and Energy, CEPT University, Ahmedabad
Dates: 12-14 December 2014
Total seats: 25 (limited free seats available)
Fees: INR 15,000 (+12.36 % service tax)

Building energy simulation has been available to researchers since almost four decades. However, it has only been in the last decade that an increase in computing power and development of graphic user interface have allowed designers to use it in commercial practice. The integration of energy and mass flow calculations in the same engine to investigate mixed mode operation of buildings, for example, natural ventilation and heating/cooling systems, is even more recent. The EnergyPlus is one of the most modern building energy simulation engines with such features. When used with the Design Builder interface, the system provides powerful design and analysis capabilities which will be explored in the 20 contact hours spread over 2.5 days of workshop.

The workshop will involve hands on experience with, with the OpenStudio Plug-in for SketchUp from EnergyPlus and DesignBuilder software. A 30 day evaluation copy of Design Builder will be provided to participants. After covering the basics, viz., building envelope, glazing and shading, internal loads and schedules, the focus of the workshop will be on testing the effectiveness of a naturally ventilated building design. The integrated CFD engine will also be used to review air flow and temperatures.

Hardware Requirements
A laptop with followings specs:
a.

A good 100% OpenGL compatible graphics adapter is required. The mid-range and better NVIDIA cards seem to be the most reliable. Some graphics adapters integrated with the motherboard we have tested are unable to run certain tools.

b.

Windows XP SP2

c.

2.4 GHz dual core processor or faster. Dual Core processors are recommended as they allow you to continue using your computer while simulations are carried out.

d.

4 GB (or more) RAM.

e.

5 GB free disk space

f.

Pointing device

g.

100% OpenGL compatible 3-D graphics adapter with hardware acceleration running in 32-bit color mode

h.

1280×1024 pixels or larger screens for efficiency during the modelling process and for displaying high-quality visualization images and walk-throughs of models and CFD results.

i. Laptop should have internet connection.
