Energy efficiency codes set minimum requirements for the energy-efficient design and construction/renovation of new and existing buildings. [Source: Cochrane & Dunn (2010), Energy Codes 101: A Primer for Sustainability Policy Makers, Working Paper, Reservation Green Lab].
The calculated or measured amount of energy needed to meet the energy demand associated with a typical use of the buildings, which includes inter alia, energy used for heating, cooling, ventilation, hot water and lighting (EU). [Source: EPBD recast, 2010/31/EU]
Energy performance requirements are based on a building’s overall consumption of energy or fossil fuel or the building’s implied emissions of greenhouse gas. [Source: Laustsen (2009) Energy Efficiency Requirements in Building Codes, Energy Efficiency Policies for New Buildings]
Rating and disclosure refers to the practice of evaluating the relative energy efficiency of a home or building and making this information known to consumers. The mechanism aims to raise consumer awareness about energy performance of and encourage building energy improvements through greater market transparency. [Source: Institute for Market Transformation]
