SAP Calculations using NHER

The UK housing stock is responsible for approximately 30% of all energy consumed (DTI, 2003). SouthFacing are actively working to reduce this burden and offer design advice and energy assessments for dwellings.

We can provide Quality Assured SAP (Standard Assessment Procedure) energy ratings under the NHER (National Home Energy Rating) scheme. This scheme assesses the energy efficiency of dwellings against the new 2006 Part L1A building regulations in England and Wales.

We can offer:

• Advice on compliance with the Building Regulations 2006
• Authorised SAP 2005 (and 2002) ratings
• Part L1A 2006 compliance checks (England and Wales)
• Authorised quality assured outputs (SAP Certificates) to demonstrate compliance to the building control body
• Draft energy performance certificates, ready for the introduction of Home Information Packs in England and Wales in 2007, plus in depth analysis of energy usage and costs
• Full BREDEM 12 calculation
• Total energy consumption and running costs
• Use these results to perform detailed low and zero carbon, shared supply (e.g. CHP) and renewable energy studies

Energy Performance in Non-Domestic Buildings

To calculate the energy performance of most Non-Domestic buildings, products such as Carbon Checker will be the appropriate solution due to the level of complexity required. Carbon Checker has been developed by Southfacing, using the SBEM calculation engine, and is now owned and managed by BuildDesk Ltd. We are also able to provide consultancy using iSBEM, should this be required.

However, for more complex building designs or those with innovative Building Services strategies, full Building Energy Simulation may be required.

Southfacing Services offer a range of Building Physics and Simulation services to enable the calculation of energy performance for these complex buildings. A range of industry standard software products are used (e.g. TAS) and we can assess energy, comfort, airflow and daylight performance for all building types.

Southfacing engineers hold many years experience in this area through working in research and for leading Consultant Engineers.

Every project is different and we tailor studies to specific design questions, programme and risk management.
