SAP calculations are essential for assessing the energy efficiency of dwellings, with a significant focus on ventilation systems, especially those incorporating heat recovery. Mechanical Ventilation with Heat Recovery (MVHR) systems are meticulously evaluated for compliance with requirements such as continuous air flow rates as outlined in Building Regulations Approved Document

Air tightness testing is vital for enhancing a building’s energy efficiency, thermal comfort, and compliance with regulations. By identifying and addressing air leaks, this process helps maintain a consistent internal temperature, reducing energy bills and carbon emissions. It also improves indoor air quality and prevents moisture-related issues, supporting the structural

The interplay between airtightness and fire safety in buildings is complex, necessitating a delicate balance between energy efficiency and safety measures. While airtight designs contribute to reduced energy consumption, they can inadvertently hinder smoke control systems, such as pressure differential systems, by limiting air leakage paths crucial for preventing smoke

The role of natural lighting in sustainable building design is pivotal, offering numerous benefits such as enhanced energy efficiency, improved occupant comfort and health, and reduced environmental impact. By decreasing reliance on artificial lighting, natural light can cut energy consumption by up to 40%, thereby lowering electricity bills and carbon

Cool roofs are designed to significantly reduce roof surface temperatures, thereby decreasing heat transfer into buildings and promoting energy efficiency. By utilising materials with high solar reflectance and thermal emittance, these roofs lower the demand for air conditioning, offering substantial energy savings and extending the lifespan of roofing materials. The

Ratio Seven Limited, based in Nantwich, Cheshire, has established itself as a leading consultancy firm in the implementation of Sustainable Drainage Systems (SuDS) for construction projects, showcasing a strong commitment to sustainability and modern construction practices. With extensive experience in the house building industry since its inception in 2008, the

Ratio Seven Limited could potentially enhance indoor air quality through consultancy, facilities management, or health and safety services, providing guidance on ventilation, filtration, and disinfection tailored to specific environments. Although not explicitly focused on air quality improvement, their expertise in relevant sectors could facilitate compliance with indoor air standards. However,

SAP calculations meticulously evaluate the energy efficiency of dwellings, with a focus on various types of mechanical ventilation systems, including centralised and decentralised systems. Centralised Mechanical Ventilation and Heat Recovery (MVHR) systems are assessed based on their thermal performance and installation location, while Specific Fan Power (SFP) test measurements are
