Applications of simulation and CAD tools in the Israeli “Green Building” Standard for achieving bioclimatic and low energy architecture

Edna Shaviv

Abstract: Current environmental assessment methods commonly use a simple ‘point hunting’ approach. As a result, developers and design teams try to obtain “cheap and easy points”. Consequently, they avoid choosing “Energy points”. Additionally, “Energy points” are achieved mainly by improving the mechanical, electrical and hot water systems, since they are easier points to handle than designing low energy buildings, especially at the advanced design stages. This is in contrast with the fact that buildings are designed to last 50 to 100 years and the mechanical systems only 15 to 20 years, at most. The new Israeli Green Building Standard attempts to overcome the deficiencies presented above by dividing the energy chapter into two parts; Building energy performance and Building services systems and by trying to make the “Building performance points” easier to handle at the early design stages. The present paper puts an emphasis on the building performance subchapter as well as on the simulation and CAD models that are applied to ensure bioclimatic and low energy building design.
