Glossary

Deep Reduction or Deep Energy Reduction is a term used in US for a deep renovation or a deep refurbishment, which aims at 75 % or more reduction in energy use compared to before the improvement. E.g. the 1000 homes challenge. [Source: GBPN, 2012]

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]

Deep retrofit or Deep Energy Retrofit implies replacing existing systems in a building with similar ones that are of higher quality and performance, which leads to a better energy performance of an existing building. The primary energy consumption includes energy used for heating, cooling, ventilation, hot water, lighting, installed equipment and appliances. After the deep retrofit the buildings consume 50% less primary energy compared to the status of theexisting building/s the retrofit (Definition mainly used in US). [Source: GBPN, 2012]
