Adam Hinge Sustainable Energy Partnerships China Building Energy Performance Rating Workshop 28 October 2013 IPEEC BEET Goals The key focus for the BEET: Improve energy efficiency of buildings in IPEEC member economies through multilateral cooperation, specifically in relation to: the development and implementation of national building energy efficiency rating systems; and enhance the development of instruments that enable effective implementation of energy efficiency policy measures in buildings. 2
BEET Workplan The BEET has undertaken to collect and analyze data by: Identifying, reviewing and summarizing building energy rating systems currently in use, or in development, in IPEEC countries. Focusing on the impact of building energy ratings on the market value of properties (at time of sale, lease or appraisal). Ascertaining the attributes of building rating systems that tend to influence such impacts. If feasible, examining other impacts of building ratings, such as on efficiency-related investment decisions by building owners. 3 Building Energy Rating provides information about the energy performance of a building, giving better information to decision makers Compares a building to its peers; compares how the energy performance changes over time Recognition for design/construction team Rating Tools can identify and diagnose performance problems
