A building’s energy consumption varies considerably according to the building’s function. Its total operational energy usage comprises regulated and unregulated energy. However, current English building regulations do not adequately cover power consumption from typically user-related activities. These include lifts, server rooms and small power loads – collectively referred to as unregulated energy usage.

BREEAM broadly defines regulated and unregulated energy consumption as follows:

= Regulated energy =

‘Regulated energy is building energy consumption resulting from the specification of controlled, fixed building services and fittings, including space heating and cooling, hot water, ventilation, fans, pumps and lighting. Such energy uses are inherent in the design of a building.’

Designers may not be able to predict how the services and fittings will be used but they can design them to be as energy efficient as possible.

= Unregulated energy =

Unregulated energy is building energy consumption resulting from a system or process that is not ‘controlled’, ie energy consumption from systems in the building on which the Building Regulations do not impose a requirement. For example, this may include energy consumption from systems integral to the building and its operation, e.g. IT equipment, lifts, escalators, refrigeration systems, external lighting, ducted-fume cupboards, servers, printers, photocopiers, laptops, cooking, audio-visual equipment and other appliances.

Unlike regulated energy use, unregulated energy consumption is usually only determined very late in the design process; it can also vary wildly throughout the building lifecycle. This is because buildings have different occupiers and tenants at various times who use space according to their needs. Some buildings can have unregulated energy accounting for 50% of total energy use.

Designers usually demonstrate compliance with part L of the Approved Document as evidence of a building’s energy efficiency. But Part L does not fully reflect reality, as regulated energy is only a part of the total. Although they can usually predict regulated energy usage, it becomes more difficult with unregulated energy as predicting user behaviour can be problematic. This means that designers should not be held accountable for total operational energy usage as it is something they can only partly influence.

Clients should have a grasp of the total operational energy usage of their buildings. It is therefore up to designers to help them understand the concepts, particularly the difficulty of influencing and prediction unregulated usage.
