For the first time, the GBPN has assessed the quality of data of building types in each of its priority regions - China, the European Union, India and the United States. The premise of the new study is that transparent, comprehensive and credible data collection and analysis are crucial for designing new policies that can help move the building stock towards zero energy. This new report entitled “Robust Building Data: A Driver for Policy Development”, reveals that there are important “white spots” in the data across the GBPN regions and that quality and availability of data vary considerably, which prevents modelling and estimation of energy efficiency potentials in buildings. The study provides a series of recommendations for overcoming these gaps and calls for a collaborative effort in improving the quality of data collection worldwide.
The GBPN convened a panel of building analysts and data experts from all four regions that were surveyed to assess the quality of data using a scoring system based on several parameters. The experts were further asked to provide guidance on how the data quality and the collection techniques could be improved.
