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
SAP calculations play a pivotal role in assessing the energy efficiency of dwellings in the UK, incorporating various elements, including heat recovery systems like Waste Water Heat Recovery Systems (WWHRS) and Flue Gas Heat Recovery Systems (FGHRS), to evaluate a building’s overall energy performance. WWHRS are recognised within the SAP
SAP calculations are integral to assessing the energy performance of residential buildings, with particular attention given to hot water systems. These calculations consider various components, such as the type and efficiency of the hot water system—be it conventional boilers, heat pumps, or solar thermal systems—to gauge energy consumption and emissions.
Airtightness is a fundamental aspect of Passivhaus design, vital for ensuring optimal energy efficiency, thermal comfort, indoor air quality, and building durability. By preventing unintentional air leakage, airtightness significantly reduces the need for mechanical heating and cooling, resulting in lower energy consumption and a reduced carbon footprint. Furthermore, a well-sealed
