Energy Assessment Package
All new-build dwellings require a SAP report to secure a Building Warrant and an Energy Performance Certificate (EPC) upon project completion. As new-build regulations evolve with more stringent targets and increasingly complex requirements, I aim to make the process of achieving compliance with Part L and Section 6: Energy, and obtaining your EPC, as smooth as possible.
To guide you through this process, I provide a comprehensive Energy Assessment Package that supports you from initial design and Building Warrant compliance through to final project completion.
The Energy Assessment service is broken down into three stages:
1. Estimating SAP
Ideally involving early input at the design stage, this consultation allows you to discuss and review multiple options. You can adjust various elements of the assessment and see the expected results. You’ll receive a concise summary of each option, including a breakdown of key components and outcomes, helping to clarify the benefits of different designs and giving you the freedom to decide how best to proceed.
2. Design / Building Warrant SAP
At this stage, I take your preferred option from the Estimating SAP and provide a detailed summary, full calculation report, and all associated documents required by Building Control for Part L or Section 6: Energy. This includes any bespoke U-value or thermal bridging calculations undertaken. I understand that changes often occur during the course of a project, and I allow for suitable minor revisions within the initial cost. It’s encouraged to keep me informed of any updates so I can amend the assessment and ensure ongoing compliance.
3. As-Built SAP & EPC
The final stage takes place near project completion. I’ll ask you to provide a simple statement confirming that all on-site conditions reflect the submitted information, along with the latest drawings. I will then update the SAP to confirm continued compliance. After a final summary review, I’ll issue the As-Built SAP Report and the EPC for the dwelling.
If required, I can also provide Sustainability Labels; however, this service incurs an additional fee due to the extra information required.
U-value Calculations
Fabric choice is becoming an increasingly important aspect of designing modern homes and improving the existing housing stock. U-values measure thermal transmittance — in other words, the rate at which heat transfers through a building element.
As part of the Energy Assessment Package, I can also provide U-value calculations as a standalone service. After discussing your design and performance targets, you’ll receive a bespoke set of calculation reports tailored to your chosen construction.
This service can also include a review of multiple variants, allowing you to compare the effects of different materials and products. This provides valuable insight into potential material cost savings and opportunities for more efficient designs.
If required, I can also provide Condensation Risk Analysis Reports for your specification.
Thermal Bridging Calculations
UA significant portion of heat loss in dwellings occurs at the junctions between building elements. Poorly detailed junctions can create thermal bridges, allowing heat to escape and reducing the overall thermal performance of a building. While it’s possible to use default figures that assume less effective junctions, performance can be significantly improved through bespoke thermal bridging calculations.
Using THERM software, I can produce custom thermal bridging calculation reports tailored to your specific construction details. These provide more accurate and often improved figures compared to default values.
For developers and construction system manufacturers, I can also provide a suite of thermal bridging calculations to support and enhance your design performance, adding further value to your service offer.
Technical Drawing & Detailing
With my background as a timber frame technician designing timber kit houses, I am well acquainted with technical drawings and experienced in drafting professional construction details. If you can provide sketches of your requirements along with any preferred notations, I can produce drawings, details, and documentation to your specifications.
