We provide full SAP assessments to demonstrate compliance with Part L Building Regulations, helping you achieve your required energy performance targets. Our in-house team also produces Energy Performance Certificates (EPCs), giving you a complete, streamlined service from design through to completion. By modelling fabric performance, insulation strategies, and system efficiencies, we ensure your project is both compliant and cost-effective.
With increasingly airtight and well-insulated buildings, managing overheating risk is essential. We carry out detailed overheating assessments in line with Part O, evaluating solar gain, ventilation strategies, and glazing performance. Our approach ensures comfortable internal environments while maintaining compliance, with practical design recommendations that support buildability and performance.
We design timber frame systems to deliver comfortable, energy-efficient buildings with strong acoustic performance. Robust Details are industry-recognised construction details that provide proven solutions for meeting acoustic performance requirements between homes, helping to reduce the need for pre-completion sound testing where applicable. Alongside this, our in-house team models thermal junctions and calculates project-specific psi values to minimise heat loss, reduce cold bridging and support consistent thermal performance across the building envelope.
We recommend engaging our energy assessors at the earliest design stage. This allows energy performance to be designed into the building fabric from the outset, potentially avoiding costly changes later in the process.
Yes, we support both residential and commercial projects. Our in-house energy assessors carry out SAP calculations for dwellings and are fully qualified to produce SBEM calculations for commercial buildings to demonstrate compliance with Part L. We also provide EPCs on completion, offering a complete, joined-up approach to energy modelling and certification.
U-values define how effectively a building element resists heat loss and play a key role in timber frame design. We tailor panel specifications, insulation types, and construction details to meet your target performance. Alongside this, we model thermal junctions and produce project-specific psi values to minimise heat loss at key interfaces, helping to achieve overall compliance and improve real-world building performance.
