The document outlines the integration of Building Information Modeling (BIM) in sustainable design, specifically in the context of architecture at the University of Salford. It emphasizes the importance of using BIM tools for decision making, compliance with environmental standards, and enhancing building performance, including energy efficiency and sustainability metrics. Case studies and examples illustrate how BIM can facilitate effective sustainable architecture through better data analysis, visualization, and design optimization.

are useful.”
– George E. P. Box

4. “Software doesn’t design sustainable
buildings, people do.”
– Elrond Burrell

5. Caveats
A UK based Architect’s perspective
BIM tools our teams use:
– Vasari, Revit, Ecotect, IES, PHPP
Sustainable Design is a HUGE topic

6. Overview
1. Sustainable Design?
2. BIM for SD decision making

53. Semi-native
Visual check / evidence within model
Generate data for credits
Generate data to export for analysis

54. Visual Check / Evidence
Man 7 Shared Facilities
One credit may be awarded where evidence provided demonstrates that
shared facilities have been provided as a consequence of consultation
feedback.
Two credits may be awarded where, in addition to the above, evidence
provided demonstrates that these facilities can be accessed without
compromising the safety and security of the building and its occupants.

56. Generate data for credits
Mat 1 Materials Specification – Major Building
Elements
Up to six credits may be awarded where evidence provided demonstrates that the major building
elements specified have either an ‘A+, A or B rating’, as defined in the Green Guide to
Specification.

58. Generate data for analysis
Hea 1 Daylighting
One credit may be awarded where evidence demonstrates that at least 80%
of floor area in each occupied space complies with the following:
• An average daylight factor of at least 2%; AND
• A uniformity ratio of at least 0.4 or a minimum point daylight factor of
at least 0.8% (spaces with glazed roofs, such as atria, must achieve a
uniformity ratio of at least 0.7 or a minimum point daylight factor of at
least 1.4%).
