Application of ASHRAE 90.1 Building Envelope Requirements for Middle East Regions (OR-16-C029)

ASHRAE 90.1 is an energy standard for buildings except low-rise residential buildings. It provides minimum design and construction requirements for most types of Residential and Commercial buildings and their systems. The objective of this technical paper is to analyze and assess, some of the building envelope values in ASHRAE 90.1 such as wall, roof, and glazing, using building energy modelling simulation techniques for different regions in the Middle East. A comparative analysis is made for thermal conductivity (U) values of walls, roof,  glazing, and solar heat gain coefficient (SHGC), based on the results from building energy modelling simulation, to analyse the energy consumption and energy savings potential and obtain optimised values for these parameters relevant to the Middle Eastern region. Also, a comparative analysis is made to examine the performance of building envelope values with Residential and Commercial buildings.
