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

Understanding air testing for extensions is essential as it ensures your new home extension is energy efficient and compliant with building regulations. By grasping the importance of air testing, you can reduce energy consumption, improve indoor comfort, and prevent issues such as dampness and mould. During the testing process, measures

In open-plan office designs, you’ve likely experienced the acoustic challenges that can hinder productivity and employee satisfaction. With noise bouncing off hard surfaces and ambient sounds disrupting work, maintaining focus becomes difficult. Addressing these issues with effective solutions like acoustic panels and sound masking systems is essential. Soft furnishings and

To ensure your residential property meets regulatory standards and enhances occupant comfort, understanding and implementing effective sound insulation is crucial. By addressing both airborne noise, like voices and music, and impact noise from physical interactions such as footsteps, you create a quieter, more tranquil living environment. Techniques like double-layered walls,
