SAP 10 Pre-Emptive Analysis

SAP10 can not yet be used for generating compliant certificates for Building Control.  However, some planning authorities, include the GLA in London, request developers to use SAP10 emission factors.

How Energist can help

Approved Document AD L is changing in England, and the proposals indicate a substantial shift in the way we build new homes.

Thicker wall insulation, triple glazing, waste water heat recovery, heat pumps and photovoltaic panels are all items that construction companies will need to consider in readiness for when the regulations change.

Although we don’t expect these changes to take effect until the autumn of 2020 we are fully aware that developers are concerned, and want to start planning now to tackle these new requirements.

Energist’s Technical Team is offering developers a unique analysis of the SAP10.1 and AD L 2020 documents. Using the Government’s own consultation papers and guides, we can report on how your current specification performs against the proposed targets, and how it can be refined to reach compliance.

You’ll receive an analysis report which studies a sample selection of your existing house designs, recommends changes to certain elements in your specification, and shows how this will reduce energy use, running costs and carbon dioxide in line with the MHCLG ‘Option 2’ model. This is the Government’s preferred approach which will see the current Target Emission Rate reduced by 31%.
