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 assumptions may not accurately reflect real-world usage, as actual conditions often demand lower set points and longer operation due to
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 testers, such as those from the Federation of European Heating and Airconditioning Associations, must be renewed every three years, contingent
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 and achieve precise measurements. Professional assessments are crucial for obtaining certifications, managing complex air leakage problems, and designing effective HVAC
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 expenses, with potential annual energy cost savings ranging from 2% to 36% for improvements, particularly in heating-dominated climates. However, many
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 and providing Energy Performance Certificates ensures that projects meet essential energy efficiency standards, while their air tightness testing helps maintain
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 insulation, with an emphasis on minimising thermal bridging, are critical steps in reducing artificial heating needs. Enhancing heating system efficiency
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, subsequently reducing the load on HVAC systems and lowering energy demands and operational carbon emissions. However, it’s crucial to balance
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 are tasked with scrutinising plans through Full Plans Applications and Building Notices, conducting regular site inspections, and offering advice throughout
Thermal comfort significantly influences SAP calculations, which are essential for determining the energy efficiency of UK buildings. Key factors impacting thermal comfort include thermal mass, insulation, ventilation system performance, and solar gains, all of which play a role in a building’s energy consumption and occupant well-being. Furthermore, precise SAP calculations
