In BIRDS, sustainability performance includes:
For this BIRDS database, a user can compare the sustainability performance of 960,000 different building component combinations for the NIST Net Zero Energy Residential Test Facility (NZERTF) located in Gaithersburg, MD. BIRDs v4.0 added options for natural gas-fired space and water heating equipment and a larger solar PV system option. The NZERTF Design as operated during its initial year of demonstration was added as a predefined selection option along with the IECC editions. Future versions will expand on the current options by introducing alternative foundation types, new building prototypes, and locations.
Note: BIRDS does not allow for comparisons of performance across different use profiles (e.g. occupancy activity) for the NZERTF.
Steps to getting answers to your sustainability questions.
Select your environmental preferences by setting the weights for each of the environmental impact categories.
BIRDS includes 12 environmental impact categories for which the user can analyze the environmental performance of a building. BIRDS also allows a user to report a single, weighted average Environmental Impact Score (EIS). In order to calculate the EIS the user must define their preferences, or "weight set" regarding the relative imporance of each environmental impact. The user can select one of the pre-defined weight sets or create their own weight set.
