Maintaining airtightness in a building is essential for enhancing energy efficiency, thermal comfort, and indoor air quality. To ensure airtightness over time, meticulously seal the building envelope using flexible caulks

SAP calculations for cooling systems in the UK rely on standardised assumptions, such as operating six hours daily at 24°C for three months, to simplify energy efficiency evaluations. However, these

An airtightness test certificate remains valid as long as the building’s airtightness characteristics remain unchanged, though there is no universal expiry date for the certificate itself. However, the certification for

Performing a DIY air tightness assessment can help identify basic air leakage issues, but it is often prudent to engage professional air tightness testers to ensure compliance with building regulations

Achieving airtightness in large commercial spaces presents a range of challenges, chiefly impacting energy efficiency and costs. Significant energy losses from air leakage can lead to increased heating and cooling

Ratio Seven offers invaluable support to house builders, property developers, and self-builders across the UK by simplifying the complexities of building regulations and compliance. Their expertise in performing SAP calculations

To optimise your heating system for improved Standard Assessment Procedure (SAP) results, several key strategies must be employed. Firstly, orienting your building to maximise solar gains and applying comprehensive thermal

The impact of airtightness on air conditioning systems is profound, influencing both the efficiency and energy consumption of buildings. When a building achieves optimal airtightness, it minimises uncontrolled air leakage,

Building Control Bodies (BCBs) are integral to the construction process in the UK, ensuring compliance with Building Regulations to protect the health, safety, and welfare of all building occupants. They
