ATSPACE Ltd, a pioneering company renowned for our commitment to compliance excellence through profound expertise and outstanding service, specialises in supporting the construction industry to create sustainable and high-performing homes. A longstanding client recently approached us to obtain Energy Performance Certificates (EPCs) for a commercial site undergoing conversion into apartments. However, as discussions deepened and a meticulous project analysis ensued, it became apparent that the client's requirements extended beyond the realm of EPCs. Their needs encompassed a comprehensive range of services imperative for aligning with the rigours of the UK's building regulations. This case study vividly illustrates our adept approach to meeting these demands, manifested through 'design stage' SAP calculations, meticulous water efficiency calculations, rigorous ventilation testing, and comprehensive sound testing.

The client's initial query, centred around EPCs, proved to be merely the tip of the iceberg. The transformation of a commercial property into a multifaceted apartment complex demanded compliance with a multitude of building regulations. Throughout an assiduous consultation phase, we adeptly parsed the intricacies and formulated a strategic roadmap:

Design Stage SAP Calculations (Part L - Conservation of Fuel and Power): At the heart of the matter was the client's need for precise calculations to gauge the energy efficiency of the envisioned building design. Our adept team embarked on SAP calculations, delving into the intricacies of the building's structure, heating system, ventilation, and lighting efficiency. The goal: seamless alignment with the benchmarks of Part L within the building regulations.

Water Efficiency Calculations at Design Stage (Part G - Sanitation, Hot Water Safety, and Water Efficiency): The apartments' future hinged on optimal water usage. Our meticulous water efficiency calculations plumbed the depths of water consumption patterns, plumbing fixtures, and appliances. With an eye on Part G, these calculations set the stage for intelligent water conservation measures.

As-built Ventilation Testing (Part F - Ventilation): A cornerstone of habitable spaces, ventilation's significance is profound. We undertook as-built ventilation testing, scrutinising the efficacy of the ventilation system against the parameters of Part F. Our insights guided necessary adjustments, fine-tuning the environment for comfort and health.

Sound Testing at As-built Stage (Part E - Resistance to the Passage of Sound): Creating a tranquil living environment necessitated a thorough understanding of sound dynamics. Our diligent sound testing regimen put party walls and floors through rigorous assessment. Compliance with Part E's mandates ensured an acoustic haven within.

Our accomplished team of engineers and consultants embraced the challenge with zeal, forging a holistic strategy for regulatory adherence. Our approach was a symphony of expertise:

• Design stage SAP calculations began with a meticulous evaluation of relevant drawings - floor plans, elevations, sections, site plans, and construction specs. These blueprints laid the foundation for SAP calculations, optimising energy efficiency and suggesting enhancements to reach requisite standards.

• Water efficiency calculations at the design stage flowed seamlessly, considering plumbing fixtures, appliances, and usage patterns. Our consultancy prowess led to pragmatic recommendations in harmony with Part G.

• Progressing to the '2nd fix' phase, our meticulous ventilation testing affirmed compliance with Part F. Pragmatic suggestions augmented indoor air quality and comfort, aligning spaces with optimal ventilation mandates.

• Sound testing, the final crescendo, validated compliance with Part E. Our team recommended sound insulation measures, crafting serene living environments.

ATSPACE Ltd's client-focused ethos and exhaustive compliance solution fostered the seamless metamorphosis of a commercial site into apartments harmonising with regulations. Through our provision of design stage SAP calculations, water efficiency calculations, thorough ventilation testing, and meticulous sound testing, we demonstrated an unwavering dedication to creating sustainable, compliant, and eco-conscious building solutions. The client lauded the results, a testament to our excellence in catering to diverse compliance imperatives.
