The Standard Assessment Procedure (SAP) is a practice adopted by the Government authorities to analyze and compare the energy and environmental efficiency of buildings to ensure that all new designs not only comply with the UK Building Regulations but also with all energy and environmental policy initiatives.
The main objective is to determine how much energy a new construction can consume while providing a given level of convenience and service delivery using standard occupancy and behavioral patterns.
SAP Report method also standardizes the performance of residential energy evaluations, so that comparisons can be drawn nationally for similar purposes.
Means to make SAP calculations
SAP estimates are based on the energy balance of new construction, taking into account a number of factors leading to energy efficiency, such as:
- Construction material
- The thermal lining of the
building fabric
- Housing air leakage features
and ventilation equipment output
- Performance and Monitoring
of Heating System
- Solar gains from housing
openings
- The fuel used to heat water,
ventilate, illuminate room space and cooling
- Adoption and incorporation of renewable energy techniques
The SAP report does not involve individual household
attributes such as household dimensions, levels of heating, and
temperature.
Also, SAP estimates can assess fuel costs and environmental impact rankings by analyzing carbon dioxide ( CO2 ) emissions.
Why are SAP calculations Important?
Since 1995, SAP tests have been a legal obligation under Part L of the Building Regulations for all new-build, residential properties in the UK. For the project to pass Building Legislation, households must attain a 'Pass' on these assessments. Without this, the Building Control Board cannot sign off a house; consequently, it cannot be legitimately advertised for lease or sale.
Since so many of the evaluation elements are relevant to the building design, it is highly recommended that the SAP scores are measured and considered at the start of the project to better notify architects, contractors, surveyors, and material suppliers.
Besides above, variables such as energy consumption and carbon emissions can be calculated accurately by the SAP specialist, thereby reducing operating costs of the house in the early-stage itself.
