Challenges and Objectives: The client sought ATSPACE's expertise in achieving compliance with Part L of the building regulations, which focuses on the conservation of fuel and power. They required assistance with the SAP calculation, water efficiency calculation, and understanding the necessary compliance measures. The project had a tight timeline, and the client needed the design stage SAP calculation promptly to obtain planning approval.

Solution Provided: ATSPACE promptly addressed the client's concerns and requirements. Recognising the urgency of the project, they engaged their energy team, which had availability for out-of-hours work, to expedite the process. Rather than the initial lead time of 30 working days, ATSPACE scheduled the SAP calculation and other services within 10 working days, ensuring compliance with the client's time constraints.

ATSPACE guided the client through the differences between conversion projects and new build projects, explaining the specific requirements for each. They highlighted that while building control did not mandate air pressure testing for conversions, it could significantly improve the EPC rating. The team discussed the importance of water efficiency calculations to meet the standards outlined in Part E of the building regulations.

Upon receiving the existing and proposed plans, along with the full building specification, ATSPACE's energy team promptly initiated the SAP calculation and water efficiency calculation. The completed calculations were delivered to the client within the promised timeframe of 10 days.

Results and Future Plans: The client received the design stage SAP calculation and water efficiency calculation within the specified timeline. With ATSPACE's assistance, the client successfully obtained planning approval and commenced construction on the site. Once the project is completed, the client intends to conduct an air pressure test voluntarily, even though it is not required by building control. This additional step has the potential to significantly improve the EPC rating by demonstrating reduced air leakage.

ATSPACE is excited about the opportunity to see the Wells Conversion project through from start to finish. By providing expert guidance, meeting tight deadlines, and delivering the required calculations promptly, ATSPACE ensured the client's compliance with building regulations and supported their goal of achieving an EPC rating of C or higher.

Lessons Learned and Key Takeaways:

1. Prompt response and efficient scheduling can help overcome time constraints in construction projects.
2. Understanding the differences between conversion and new build projects is crucial for compliance with building regulations.
3. Conducting voluntary tests, such as air pressure testing, can result in substantial improvements in the EPC rating.
4. Collaborating closely with clients and promptly addressing their concerns fosters successful project outcomes.

Overall, the Wells Conversion project demonstrates ATSPACE's commitment to providing tailored solutions, expert advice, and efficient services to help clients navigate complex building regulations and achieve their project goals.
