Energy Management and Building Controls publications
BRE has produced a range of publications and studies in various formats which are list below:
BRE briefing paper - Gaining Value from ESOS Audits
Shabir Hussain and Dr Andy Lewry
This briefing paper describes ESOS (the Energy Savings Opportunity Scheme). The first part outlines the basic principles of compliance to ESOS. The second part discusses the value organisations can obtain from following the recommendations given in an ESOS energy audit, instead of viewing it merely as a ‘tick box exercise’ in order to meet compliance.
Compliance should not be seen as a cost or a burden to a business, but as an opportunity to reduce risks, and improve efficiency and profitability by implementing simple improvements at no or little cost. The regulation aims to encourage energy efficiency in larger businesses; many organisations have already recognised the business and financial value of doing this. This briefing paper aims to help those who do not already have energy-saving measures in place to choose between the various ways of complying with ESOS in order to maximise the value for money they can achieve.
BRE Briefing Paper: Energy management and building controls (produced with ESTA) by Andy Lewry
Download for free
The control of energy in non-domestic buildings is generally poor, despite the substantive savings that can be made. This technical briefing note informs readers of the benefits of the European standard BS EN15232:2012  and helps them to navigate through the standard. It highlights the points to consider when deciding which controls would best suit a company’s needs, and includes a guide to best practice.
BRE Paper: Bridging the gap between operational and asset ratings – the UK experience and the green deal tool by Andy Lewry - Download for free
To truly understand how a building uses energy you need to know something about the building itself and about how it is used. In current parlance, that requires both an Asset and an Operational energy rating. The higher the numeric rating, the worse the building is, and the greater the opportunity to reduce carbon emissions by improving the building itself. However, the asset rating provides no information about how the building is operated in practice.
BRE Study to assess barriers and opportunities to improving energy efficiency in cooling appliances/systems – Examines policy options and measures that offer the greatest potential for saving energy used for air conditioning in Europe - Free download available.
Published July 2016 – DECC study on Energy Use by Air-Conditioning
This study comprises several different elements, each directed at improving DECC’s understanding and characterisation of UK electricity consumption by air conditioning in non-domestic buildings; especially that used to support the cooling function (rather than air handling). These include: analysis of measured consumptions; examination of the contents of air conditioning inspection reports and energy performance certificates; a literature search; and the development of procedures to extend the scope of DECC’s product policy model as applied to air conditioning - free download available.
