Energy Simulation Aided Design for Buildings Except Low-Rise Residential Buildings

ASHRAE Standard 209 describes a methodology to apply building energy modeling to the design process. The Standard Project Committee recognizes the important role building energy modeling plays in informing the design and operation of low-energy buildings. The standard was created to define reliable and consistent procedures that advance the use of timely energy modeling to quantify the impact of design decisions at the point in time at which they are bieng made. The committee believes such an approach will improve modeling effectiveness, realize greater savings, and support achieving increasingly aggressive energy savings targets.
