Building and system design optimization 37
Find out appropriate passive design strategies
Optimize orientation and arrangement of internal spaces
Provide adequate shading to critical building surface
and fenestrations
Find out SHGC and WWR and/or SRR Re-evaluation of
opening size and
If No If No glazing properties
Check for adequate daylight level
within the daylighted area
If Yes
Finalize fenestration design (shading design, size of the openings,
glazing properties, and so on)
Design of efficient artificial lighting design
Provision of lighting controls
Figure 19 Step for building design optimization and analysis
Example
A case study has been provided below to explain the methodology described above and also to
demonstrate the roles of different simulation tools in the process.
Climate-responsive building design by using computer simulation software:
This is an example of a daytime-use government building and the recommendations have been
proposed for incorporating solar passive interventions through a computer simulation software.
Building description
An administrative building is proposed in the composite climate of Patna. The proposed building
plan, comprises one double-loaded and three single-loaded corridors around a central courtyard.
This is G+1 building with total built-up area of 2325 m (approximately) and only less than 20% of
2
the area is air-conditioned. The proposed WWR is within 20% and all the floor depth of office areas
are within 7 m.
