Active system

The Home Quality Mark One, Technical Manual SD239, England, Scotland & Wales, published by BRE in 2018, suggests that active systems are:

Any home systems that require active operation or maintenance. This includes common home systems such as:

• Heating and hot water systems.
• Ventilation systems.
• Low and zero carbon technologies.
• Comfort cooling systems.
• Appliances.
• Showers or baths, WCs.
• Lighting.
• Safety systems (e.g. smoke detectors, fire alarms and sprinklers).
• Security systems.
• Smart devices (e.g. as smart meters).

As well as any other systems, which may be less typical, such as:

• Electric car charging points.
• Living roof systems (e.g. green roofs).
• Flood resilience measures.
• Drainage systems or strategies (e.g. SuDS).
• Temperature control measures (e.g. active external shading).
