Blower door testing is a vital diagnostic procedure used to assess a building’s air-tightness, playing a significant role in improving energy efficiency, enhancing indoor comfort, and ensuring compliance with building regulations. By creating a pressure differential using a powerful fan, the test identifies air leaks within the building’s envelope, allowing
To ensure your building achieves the desired energy efficiency and ventilation standards, thorough preparation for air permeability testing is essential. By completing all structural work, sealing unintended openings such as gaps around pipes and cracks in building materials, installing temporary seals on features like chimney stacks and ventilation ducts, and
SAP calculations are fundamental to assessing the energy efficiency of residential properties in the UK, ensuring they meet building regulations and qualify for an Energy Performance Certificate (EPC). This procedure encompasses various aspects such as insulation, heating systems, ventilation, and renewable energy sources, influencing both the environmental impact and cost-effectiveness
In the realm of building construction and regulation, design air permeability and as-built air permeability serve distinct yet interconnected roles. Design air permeability is a calculated value set during the design stage, aiming to predict a building’s energy efficiency and ventilation needs. In contrast, as-built air permeability is a post-construction
Smart building technologies epitomise the sophisticated convergence of various systems and technologies, designed to enhance efficiency, sustainability, and responsiveness to occupants’ needs. By leveraging the Internet of Things (IoT), building automation systems (BAS), and a robust IT infrastructure, these buildings optimise operations such as temperature regulation, lighting management, and security
Cool roofs offer a sustainable solution for reducing energy consumption, mitigating urban heat islands, and extending the lifespan of roofing materials, thanks to their ability to reflect sunlight and emit absorbed heat efficiently. Entities like Ratio Seven play a pivotal role in implementing these technologies by providing expert consultation on
Natural ventilation in buildings provides substantial benefits by enhancing indoor air quality, reducing energy consumption, and promoting occupants’ health and comfort, all while supporting environmental sustainability. By allowing fresh air to flow through operable windows, skylights, and vents, this approach minimises the reliance on mechanical systems, yielding significant cost savings
Effectively communicating SAP results to clients is essential for ensuring they understand the energy efficiency and compliance of their building projects. Utilising the expertise of a company like Ratio Seven, which specialises in energy and building consultancy services, can greatly enhance this process. By providing clear explanations of energy efficiency
A blower door test is a systematic procedure used to evaluate the air-tightness of a building, essential for assessing energy efficiency, indoor air quality, and overall building performance. The test involves using a calibrated fan mounted in an exterior door frame to pressurise or depressurise the structure, with a manometer
