Standard Assessment Procedure
Encyclopedia
The Standard Assessment Procedure (SAP) is the UK Government's recommended method system for measuring the energy rating of residential dwelling
s. The first version was published in 1995, to be replaced by newer versions in 1998, 2001 and 2005. It calculates the typical annual energy costs for space and water heating, and, from 2005, lighting. The CO2 emissions are also calculated.
SAP 2005 has been used as the basis for checking new dwellings for compliance with building regulations in the United Kingdom requiring the conservation of fuel and power since 6 April 2006 (England & Wales: L1 Approved Document), 1 November 2006 (Northern Ireland Technical Booklet F1) and 1 May 2007 (Scotland Technical Handbook 6, Domestic).
A simplified version of SAP 2005, RDSAP, will be used to produce the energy report and Energy Performance Certificate
in Home Information Packs
(HIPs). A new document was published by the UK Government in 2007, looking towards SAP and energy standards in the future.
A number of comparisons have indicated that SAP does not provide an accurate model for low-energy buildings.
The Standard Assessment Procedure evolved from the National Home Energy Rating
scheme, which was based upon the Milton Keynes Energy Cost Index created for the Energy World
demonstration buildings in the 1980s.
Dwelling
Dwelling, as well as being a term for a house, or for living somewhere, or for lingering somewhere, is a philosophical concept which was developed by Martin Heidegger. Dwelling is about making yourself at home where the home itself is a building that is a house...

Energy Performance Certificate
Energy Performance Certificates were introduced in England and Wales on 1 August 2007 as part of Home Information Packs for domestic properties with four or more bedrooms . When the requirement for HIPs was removed in May 2010, the requirement for EPCs continued. The scheme for HIPs was extended...

Home information pack
Under Part 5 of the Housing Act 2004 a Home Information Pack , sometimes called a Seller's Pack, was to be provided before a property in England and Wales could be put on the open market for sale with vacant possession. There is separate legislation for Scotland that requires anyone selling a...

Energy World was a demonstration project of 51 low-energy houses constructed in the Shenley Lodge area of Milton Keynes, United Kingdom. The project was promoted by the Milton Keynes Development Corporation and culminated in a public exhibition in August and October 1986 that attracted...
