Design Tool for IAQ Analysis

 

Session 14, Paper 3, CIBSE ASHRAE Technical Symposium, Dublin, Ireland 3-4 April 2014

 

BREEAM In-Use (BIU) is an environmental assessment scheme specifically aimed at helping building managers reduce running costs and improve environmental performance of existing buildings. After operating in the UK since 2009, the International BIU scheme was launched in 2013 with a view to providing a universally understood and comparable rating for buildings across the world.
The most challenging aspect of the international adaption was the development of a methodology for assessing building energy performance. This paper reviews the design development behind the energy rating tool; sets out the methodologies which underpin the asset and operational energy rating calculations and; considers opportunities for future development and refinement.
