Welcome to Compass Energy Consulting Engineers Limited :: UK SAP Calculations Part L, L1, L2, Carbon Reduction, SAP, Energy Consultants, Mechanical and Electrical Design.

The Building Regulations Part L will still be separated into dwellings (part L1) and non-domestic buildings (part L2).

For dwellings the SAP 2005 will replace SAP 2001 with the more relaxed Target U-value and Elemental Methods becoming redundant.

For all other non-domestic buildings two methods will replace the Elemental, Whole Building and Carbon Emission Calculation Methods. The two new methods will be very distinctive, the Simple Building Evaluation Method and a simulation based route. The SBEM will be solely applicable to extremely basic buildings such as warehouses etc. The new simulation method will be similar to the previous Carbon Emission Method with other elements built in, and will form the compliancy route for the majority of non-domestic buildings.

Ce2 are geared up to undertake all domestic and non-domestic Part L requirements both under current legislation and the amended 2006

Currently for retail buildings there are only two possible methods of demonstrating compliance, the Elemental Method and the Carbon Emission Calculation Method (CECM). Whilst theoretically there is a choice, in practice the Elemental Method is very restrictive and demands a minimum level of performance from each individual building element i.e. floor construction, wall construction, roof, windows, doors, heating, lighting etc all must comply. The CECM however allows complete flexibility since a combined performance of all elements is considered.

Using the CECM we are able to pre-create the client's building and liaising with architects reduce project costs substantially by optimising the building construction fabric. We can also for see and solar gains on sun spots using the thermal modeling software.

The CECM requires 3D simulation for a minimum of two buildings, a Notional Building and the Actual Building. Construction of the virtual buildings must only be carried out using approved BEEM software. Using the software we are able to fine-tune the modeling/simulation process to the individual needs of the client. We not only support the work of the engineer, but also the architect and developers.

Ce2 routinely carry out building simulations using the CECM and have since April 2002 incorporated the requirements of the Approved Document L2.

Our Role:

Collate information regarding construction details and building layout.

Computerised 3D virtual construction of the proposed building.

Complete annual 3D simulation of the proposed building with Met Office weather data.

Annual Carbon Emission Calculations for the proposed building.

3D virtual construction and annual simulation of notional building (as required by L2) Assessment of Part L2 Compliancy.

Proposal, if required, for alterations to original design to obtain Part L2 Compliancy.
