An Overview of the Green Building Performance Database

Table 2

Data processing methods used in representative building performance databases.

Databases	Data sources	Applications
DECC (Japan)	Surveys conducted by industry, the government, and university research institutions	(1) Provide raw data for the further analysis of energy, water consumption, and carbon dioxide emissions and for making long-term carbon dioxide emission plans; (2) Provide specific energy consumption benchmarks for buildings of different regions/functions/scales
BPIE (EU)	Government surveys; other databases	(1) Provide the prototype of the EU Building Stock Observatory, so as to monitor the implementation of energy policies in the EU member states; (2) Help develop the building energy consumption map and find areas of poor energy performance; (3) Serve 20 tool databases including the IEA Buildings Energy Efficiency Policy Database (BEEP)
BPD (the U.S.)	Government surveys; other databases	(1) Help evaluate the energy use intensity for different types of buildings; (2) Help develop the US building energy consumption map for regional building performance research
IEQ (the U.S.)	Web-based occupant surveys	(1) Foster the comparative study on IEQ performance between LEED-certified buildings and conventional buildings; (2) Predict building thermal comfort
BOSSA (Australia)	Web-based occupant surveys; on-site measurements	(1) Provide reference for Australian Green Star/NABERS performance ratings; (2) Provide data support for nearly 30 companies and institutions including Canon, AECOM, and ARUP
