SAP calculations are an essential requirement for compliance with the UK’s energy efficiency standards, particularly those stipulated in Part L of the Building Regulations, ensuring new constructions and significant modifications align with current energy performance criteria. The process entails collecting detailed building data, evaluating the design at both the initial

Navigating the intricate regulations and preservation guidelines for listed properties in the UK is essential to maintain their historic integrity. Obtaining Listed Building Consent and aligning with local planning authorities can be a complex and lengthy process, particularly for properties like blocks of flats with shared spaces. The financial burden

Airtightness testing is essential in the pursuit of various building certifications by ensuring that structures meet designated standards for energy efficiency, indoor air quality, and overall performance. This testing, typically conducted using methods such as blower door tests (e.g., ASTM E779, ASTM E1827), helps identify air leaks that could account

SAP (Standard Assessment Procedure) calculations, mandated under Part L of the UK Building Regulations, do not directly quantify a building’s form factor but inherently consider its influence through various elements. These calculations rely heavily on the thermal elements, such as walls, floors, and roofs, assessing their U-values to determine energy

SAP and SBEM calculations are integral to evaluating the energy performance of buildings across the UK, each catering to distinct types of structures. SAP is dedicated to domestic dwellings, offering a detailed assessment that encompasses factors like insulation, heating, and construction materials, thereby ensuring accurate reflection of energy efficiency and

After an airtightness test, the comprehensive documentation serves to both verify the building envelope’s airtightness and offer valuable insights for necessary improvements. The primary test report outlines the methodology, detailing standards like AS/NZS ISO 9972:2015 or ASTM E779, and presents key metrics such as normalised air leakage rates and equivalent

Understanding the early design process in construction projects is vital, as it sets the stage for success by defining objectives, scope, and requirements with input from architects, engineers, and stakeholders. At Ratio Seven, we recommend integrating Standard Assessment Procedure (SAP) calculations early on to ensure energy efficiency and sustainability. These

In the ever-evolving world of construction, managing sound transmission is essential to ensure occupant comfort and privacy, especially as urban living becomes denser. Sound transmission, whether airborne from talking, music, or traffic, or structure-borne from vibrations like footsteps and moving furniture, poses significant challenges in modern methods of construction. Lightweight

Converting your basement into a functional living space, be it a home theatre, guest bedroom, or office, necessitates effective sound insulation to ensure comfort and peace throughout your home. By understanding how sound travels through airborne, structural, and flanking paths, you can strategically address these areas using specialised materials like
