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,

Understanding air permeability is essential in building design as it determines how much air can pass through the materials of the building envelope, impacting energy efficiency, indoor air quality, and comfort. Key factors include the materials used, construction quality, and design elements. Natural ventilation, using natural forces like wind and

You can’t underestimate the importance of SAP (Standard Assessment Procedure) calculations when valuing properties in the United Kingdom. These assessments are crucial in determining the energy efficiency of a building, directly influencing its market appeal and overall value. With an eye on factors like heating, insulation, lighting, and renewable energy,
