National Home Energy Rating
From Wikipedia, the free encyclopedia
The National Home Energy Rating Scheme (NHER) is both a UK organisation and a rating scale for the energy efficiency of housing.
The NHER is owned and operated by National Energy Services (NES). NES is a trading subsidiary of the National Energy Foundation, an independent charity set up in 1988 to promote energy conservation and provide help to improve energy efficiency in residential buildings.
The NHER scale runs from 0 to 10, with 10 being best. It uses different criteria than the SAP (Standard Assessment Procedure) rating. The NHER rating takes into account the local environment and the effect it has on the building's energy rating. The NHER calculates the costs of space and water heating, but adds cooking, lights and appliances to give a comprehensive picture of energy usage in the home.
An average dwelling in England would currently score between 4.5 and 5.5. A building meeting current United Kingdom Part L1 Building Regulations would probably score higher, perhaps around 8.0 or more.
