ASHRAE Announces Launch of As-Designed Portion of Building EQ Portal

March 31, 2018

ASHRAE has announced the launch of the As Designed portion of the Building EQ Portal that was developed by Carmel Software (the administrator of gbXML). Both the In Operation and As Designed evaluations are now available in the Building EQ Portal. The As Designed rating compares potential building energy use to the baseline performance of similar buildings using a simulated standardized energy use model:

1. Based on a building's physical characteristics and systems
2. Independent of occupancy and operating variables
3. Allows comparison of potential energy performance between buildings with very different operational and occupancy profiles
4. Identifies whether a building is achieving the full design potential as compared to actual energy performance as shown in the In Operation rating
5. Models only the candidate building for consistency between the two ratings
6. Applicable to both new and existing buildings.
