What is Ella’s Law?

Ella’s Law, formally known as the Clean Air (Human Rights) Bill, is a proposed UK legislation aimed at establishing a legal right to clean air for all citizens. Named after Ella Adoo-Kissi-Debrah, a nine-year-old girl whose death in 2013 was attributed to air pollution, the law seeks to enforce stricter air quality standards and hold...

What is the Energy Star?

Energy Star is an internationally recognised certification programme that identifies and promotes energy-efficient products, buildings, and practices. In the UK, it is often referenced in the context of energy-efficient appliances, heating systems, and building materials. While the Energy Star programme is primarily associated with the United States, its principles align with UK Building Regulations and...

What are Energy Related Products (ERP)?

Energy Related Products (ERP) refer to products that consume energy during their use, including household appliances, heating systems, ventilation equipment, and lighting. The ERP framework, established under the European Union’s Energy Efficiency Directive, aims to improve the energy efficiency of such products by setting minimum performance standards and requiring energy labelling. In the UK, ERP...

What is an Energy Recovery Ventilator (ERV)?

An Energy Recovery Ventilator (ERV) is a mechanical ventilation system that exchanges stale indoor air with fresh outdoor air while simultaneously transferring heat and moisture between the two air streams. This process improves indoor air quality (IAQ) and reduces energy consumption by pre-conditioning incoming air, making it more efficient than traditional ventilation systems. ERVs are...

What is the minimum intermittent extract rate for a utility room?

The minimum intermittent extract rate for a utility room in the UK is typically 30 litres per second (l/s). This rate ensures effective removal of moisture and pollutants, maintaining air quality and preventing damp or mould issues. Compliance with Building Regulations Part F is essential for optimal ventilation performance. Understanding the Minimum Intermittent Extract Rate...

What Minimum Free Area Must Purge Ventilation Openings Provide in Habitable Rooms?

In habitable rooms, purge ventilation openings must provide a minimum free area of 1/20th of the floor area, as per UK building regulations. This ensures adequate airflow to remove stale air and moisture, maintaining indoor air quality and preventing issues like damp and mould. Always consult local guidelines for specific requirements. Understanding Purge Ventilation Requirements...

Can I Convert a Cellar Without Planning Permission?

Yes, you can convert a cellar without planning permission in the UK, but only if the ceiling height is at least 2.4 metres, there is separate access, and the space is not designated as a bedroom. However, building regulations must still be followed to ensure safety and compliance. Understanding Cellar Conversions and Planning Permission Converting...

How Should the FLUXO Units Be Positioned for Optimal Airflow?

FLUXO units should be installed as high as practically possible on an external wall, ideally no more than 400mm down from the ceiling, to ensure efficient airflow and compliance with UK building regulations. Pairing units in habitable rooms enhances air balance, with one unit extracting stale air while the other supplies fresh air. Understanding FLUXO...

Why Might I Use the AUREN Automatic Mode?

The AUREN Automatic Mode optimises air quality by adjusting ventilation based on humidity and twilight sensors, ensuring efficient heat recovery and energy savings. It operates at medium speed during the day and reduces to night speed when needed, maintaining comfort while minimising noise and energy consumption. Understanding the AUREN Automatic Mode The AUREN 160 Single-Room...
