Simulation for environmental engineering - Case studies
Key concepts
- practical application of modelling and simulation demonstrated by case studies
in design support and performance evaluation for environmental engineering;
- simulation system examples.
Course material (initial):
Introduction
The overall performance assessment design should ideally involve an integrated approach
using modelling and simulation as opposed to the currently used traditional engineering
techniques.
Areas covered by building and energy simulation models are numerous and varied and
include:
- conduction modelling
- air/fluid flow modelling
- plant side modelling
- insolation analyis
- lighting studies
- building climatic interaction
- electrical power consumption modelling
The best way to illustrate both several application areas and modelling approaches is
by presenting case studies.
The following examples, provide insight into some assessment tasks which are
representative of particular responsse to specific design questions . Further,
they do not represent an exhaustive list of assessment task types or definitive
modelling approaches.
A wide range of
tools are now available to help architects and engineers in the design and
performance assessment of the build environment. The principal tools employed
in these case studies are ESP-r and
RADIANCE.
