Energy Audits and Surveys
Energy audits and surveys are investigations of site energy use aimed at identifying measures for cost and energy savings. They are an essential part of the effective control of energy costs and should be undertaken regularly, typically every three to five years.
With the introduction of ESOS, all large organisations, need to satisfy themselves that they are getting good value from their expenditure on energy. Audits and surveys, combined with routine monitoring, provide the vital information needed to ensure that energy is managed properly.
Most organisations already recognise that efficient energy use can not only reduce operating costs but also produce important environmental benefits.
With proper guidance, organisations throughout all sectors can benefit, whether studies are carried out in-house or with specialist outside assistance.
We all now have a responsibility to conserve natural resources and to reduce the harmful emissions that the combustion of fossil fuels can produce. Many organisations find that a responsible environmental attitude plays an important part in promoting their activities.
Nevertheless, the financial rewards are normally the underlying reason for implementing energy efficiency measures. Every pound saved on energy costs could increase profits directly by the same amount.
The CIBSE Applications Manual AM5 (Energy Audits and Surveys) authored by NIFES provides clear terms of reference for a well structured approach.
Generally for most organisations, the report provides the following:
- Adaptation of the appropriate strategy
- Audit and Survey of the site/s
- Maximisation of Energy Supply opportunities
- Identification of Energy Use
- Boiler Plant
- Space Heating
- Domestic Hot Water
- Electrical Power and Lighting
- Air Conditioning and Ventilation
