For example, the state of California began implementing energy-efficiency measures in the mid-1970s, including building code and appliance standards with strict efficiency requirements. During the following years, California's energy consumption has remained approximately flat on a per capita basis while national US consumption doubled. [ 9 ]
Energy performance certificates (EPCs) are a rating scheme to summarise the energy efficiency of buildings. [4] [5] The building is given a rating between A (Very efficient) - G (Inefficient). The EPC will also include tips about the most cost-effective ways to improve the home energy rating. Energy performance certificates are used in many ...
Depiction of New York World Building fire in New York City in 1882. Building codes in the United States are a collection of regulations and laws adopted by state and local jurisdictions that set “minimum requirements for how structural systems, plumbing, heating, ventilation, and air conditioning (), natural gas systems and other aspects of residential and commercial buildings should be ...
The Energy Efficiency Council (EEC) is a body designed to help companies undertake energy efficiency measures, providing a platform for energy efficiency and cogeneration products and services, and is thus used by commercial building owners to find consultants and contractors. The council was formed in 2009, and incorporates the members and ...
The project developed a heat recovery air exchanger (HRV), hot water recovery, and a blower-door apparatus to measure building air-tightness, techniques that became common in low-energy building in other parts of the world. [9] Orr would go on to apply many of those techniques to retro-fitting existing buildings to improve energy efficiency ...

Energy monitoring through energy audits can achieve energy efficiency in existing buildings. An energy audit is an inspection and analysis of energy use and flows for energy conservation in a structure, process, or system intending to reduce energy input without negatively affecting output. Energy audits can determine specific opportunities for ...
In Ireland, the building energy ratings are in existence since 2007. In this country Building Energy Rating (BER) is used as EPC. The scheme was mandatory for new dwelling and in 2008, its use was extended to non-residential and public buildings, in 2009 the HERS cover the all types of buildings. BER is a calculation based HERS.
