Our team provide the full range of regulation compliance services and can assist in the development of compliant buildings at an early stage in the project. We can use modelling data to help establish and meet sustainability targets for your development.
Part L Calculations (SAP & SBEM)
Part L calculations are required for new build properties and conversion/refurbishments where material changes are proposed. Our fully accredited team can provide Standard Assessment Procedure (SAP) and Simplified Building Energy Model (SBEM) calculations for Part L compliance. No project is too big or too small, we work on one-off dwellings and large complex mixed-use developments.
We always undertake Part L calculations as part of a consultancy service, by not only looking at compliance but always looking objectively and advising whether a more economic or sustainable route can be taken. We ensure we comply with the latest updates through our Government approved software.
Energy Performance Certificates (EPC)
An EPC is required whenever a property is built, sold or rented and is needed before marketing. We provide EPCs for all types of projects for domestic and non-domestic properties. Our team is fully accredited and independently audited against government criteria for the production of EPCs.
Display Energy Certificates (DEC)
Public buildings over 250m2 that are frequently visited by members of the public are required to display a DEC in a prominent place. Our assessors are fully accredited and independently audited against government criteria for the production of DECs.
Psi Value Calculations
Thermal bridging (psi value) calculations are a measure of the heat loss through thermal bridges (junctions in the building fabric). It is estimated that as U values improve up to 30% of the remaining heat loss in a building could come from poorly detailed junctions.
Psi value calculations play an important part in ensuring that a building has been detailed in the most efficient way possible. Our trained assessors can provide these calculations to BS standards suitable for use in both Part L and Passivhaus calculations.
Part G Calculations
Water efficiency calculations can be provided to assist in compliance with Part G of the Building Regulations. For design stage we will provide a performance specification for sanitary fittings and update using supplied fittings for as built calculations.
Sustainability Impact Assessments (SIA)
A SIA is a useful check to see whether a course of action – be that relocating, commencing new build or any other organisational change – has a broadly beneficial or detrimental effect on the use of resources, pollution and your carbon footprint. We can use your SIA structure or develop a bespoke format for you.
Minimum Energy Efficiency Standards assessment (MEES)
MEES regulations require all buildings to meet a minimum energy standard of band E. We are able to undertake energy surveys and provide advice in order to meet these regulations through enhancements to the building services and fabric to meet MEES requirements.
Retrofit Assessors are trained to undertake a retrofit assessment for dwellings in accordance with PAS 2035. The activities completed within the retrofit assessment include the production of an RdSAP assessment, a detailed floor plan, a condition report and an occupancy assessment. The data collected from these sources is used by the Retrofit Coordinator to formulate a medium-term improvement plan. Accredited Domestic Energy Assessors (DEA) are well placed to become qualified Retrofit Assessors due to their extensive knowledge and experience with RdSAP methodology and assessment of existing dwellings.
