Sapper version 7 is the ideal design tool for showing compliance with Building Regulations ADL1A, Northern Ireland Technical Booklet F1 August 2006, and Scottish Technical Handbook 2007 Domestic Section 6. It checks compliance by comparing the Dwelling Carbon Emission Rate with the Target Emission Rate derived from a notional dwelling of the same size and shape.
It also includes a facility to check compliance for Dwelling extensions.It will test for the Fabric Standards, Comparative Heat Loss method and the total dwelling emissions methods as required by ADL1B and in Scotland it will show compliance with Technical Standards section 6.2.9 U-values method and the Compensatory approach.*

The Standard Assessment Procedure (SAP 2005 version 9.80) is the Government's standard procedure for assessing home energy efficiency. The SAP is intended to give householders, architects, builders etc. a measure of the overall efficiency of a home in a way that is simple and easy to understand.

The SAP rating is based on the energy costs associated with space heating, water heating, ventilation and lighting, less cost savings from energy generation technologies. It is adjusted for floor area so that it is essentially independent of dwelling size for a given built form. The Environmental Impact Rating is expressed on a scale of 1 - 100, the higher the better.

Having calculated the DER and TER, if the dwelling emissions are too high, Sapper version 7 now includes a diagnosis tool to give help and guidance on how to achieve compliance. This makes the program an invaluable design tool.

There are five criteria to demonstrate compliance with the building regulations.

• The dwelling carbon emissions (DER) must not be more than the target carbon emissions (TER). The TER is calculated for a notional building with standard characteristics.
• Limiting design flexibility by meeting standards for the building fabric.
• Limiting the effects of solar gain in summer.
• Commisioning of heating and hot water systems.
• Providing information - operating and maintenance instructions.

• materials used for the construction of the dwelling
• thermal insulation of the building fabric
• ventilation characteristics of the dwelling
• efficiency and control of the space and water heating systems
• solar gain characteristics of the dwelling, and its region.
• the fuels used for space and water heating, ventilation and lighting
• renewable energy technologies

It is an invaluable design tool for any architect who wants to make sure that the design is energy efficient and that it complies with the Building Regulations. Building Control Officers like the ease of recording the data and checking the U-values.

SAPPER version 7 allows the user to browse the government's boiler efficiency data file and select an appropriate boiler. The SEDBUK datafile has detailed information on about 3500 gas and oil fired and solid fuel boilers and can be viewed at www.sedbuk.com or by clicking here
