An EIU U.S. survey of building sector executives commissioned by the GBPN in collaboration with IMT finds that tackling rising energy consumption in U.S. buildings will require a more coordinated and coherent approach to energy efficiency codes and regulation, one that is more focused on retrofits—where most potential gains lie. It is also crucial to develop new financing mechanisms that help institutional investors assess the risks associated with energy-efficient projects.
Deep Refurbishment or Deep Energy Refurbishment means to bring something back from a state of reduced efficiency to a better state with ‘deep’ indicating a very substantial improvement of the energy use. [Source: GBPN, 2012]
Deep Renovation or Deep Energy Renovation is a term for a building renovation that captures the full economic energy efficiency potential of improvements. This typically includes a focus on the building shell of existing buildings in order to achieve very high-energy performance. The renovated building consumes 75% less primary energy compared to the status of the existing building before the renovation. The energy consumption after renovation for heating, cooling, ventilation, hot water and lighting, is less than 60 kWh/m2/yr. (Definition often used in Europe) [Source: GBPN, 2012]
