Part L2A: SBEM calculations and Dynamic Simulation Modelling (DSM)
With over 6 years of experience in Part L Building Regulations compliance, out team of Energy and Sustainability Assessors have gained an enviable reputation for providing a responsive turn-around (given the necessary information), as well as for liaising with their clients to provide advice to achieve cost effective compliance.
Stroma use CLG-approved software in order to prove compliance with Part L2A and have a wealth of experience using both SBEM and DSM software. DSM modelling allows our Energy Assessors to provide a higher level of accuracy to their calculations, as well as enabling Stroma to assess any building, regardless of its complexity or size.
Our process allows us to work from specifications and drawings provided by our Client to complete the calculations.
Where buildings fail to meet the criteria for compliance, we begin the process of applying realistic and sensible improvements to a number of areas of the specification in order to provide our Client with a compliant solution.
Alongside this process, for larger or more complex projects, Stroma Energy Assessors will attend design team meetings, as required, providing a more integral consultancy service to help guide a project towards eventual cost effective compliance and thus we can play a major role within the design process.
As all of our assessors are part of our Secretary of State Approved Accreditation Scheme for Energy Assessors, we are also able to produce Energy Performance Certificates (EPCs) for new and existing Non-Dwellings.
What Part L2A calculations involve
Building Regulations Part L2A require a calculation to be performed to assess the CO2 emissions from the building (BER) against a target emission rate (TER). In addition to this, calculations also take into account four other criteria: the limiting of design flexibility for the building envelope, limiting the effects of Solar Gain in summer, the quality of construction and commissioning building fabric and provision of information.
The calculation performed by Stroma embraces Criteria 1, 2 & 3, whereas Criteria 4 and 5 should be provided by the developer or members of their design team.
The BER is calculated based upon the thermal performance of the building, and the energy used for the fixed building services within.
