Briefing Paper: Energy management and building controls

Published 29 April 2016. Price: Free download

 

 

 

 

 

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 [1] 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.

Operators of commercial and public (ie non-domestic) buildings need clear and realistic guidance on targeting energy running costs for their properties and on the potential savings available. At their disposal are two seemingly irreconcilable indicators of performance: the asset rating (eg energy performance certificate or EPC), which provides a theoretical assessment of the asset under standard ‘driving conditions’ typical of that type of building in that location; and the operational rating (eg display energy certificate or DEC), which is based on energy bills so gives no indication of how much lower running costs could be. To truly understand how a building uses energy, it is necessary to know how the building has been designed and how it is used; this requires both an asset rating and an operational rating.

The difference between these ratings – or between the predicted and actual performance of buildings – is known as the ‘performance gap’. This Information Paper looks at a way to bridge this gap and bring together these two assessments using the Green Deal assessment tool for non-domestic buildings, which allows the input of non-standard operating conditions, hours of operation and occupancy patterns. By defining these aspects of the building ‘in use’, the predicted energy performance of the asset can be brought closer to the in-use reality.

This publication is aimed at all those working to identify energy waste and deciding on energy-saving measures and programmes.

ID09 Information Paper - Producing the business case for investment in energy efficiency

Published 02 March 2015    Price: £15.00 (£18.00 for soft copy)

One of the biggest obstacles to the uptake of low-carbon measures is the production of a poor business case. The Dragons’ Den scenario, in which entrepreneurs pitch their ideas to secure investment, holds in that unless the business case stacks up and can take close scrutiny the idea will be thrown out no matter how good it is. Rarely do the benefits of energy savings alone justify investment, but this is starting to change with recent 10% year-on-year increases in energy prices. However, reduced maintenance and increased productivity need to be factored in if the business case is to stack up.


This Information Paper provides guidance on how a business case should be put together. It focuses on helping technical staff to speak the same language as their financial counterparts, illustrating the importance of the ‘do-nothing’ scenario, highlighting the risk to the business and putting potential benefits into context. It also explains how to plan a presentation in advance so that the presenter is able to put forward a compelling case.


This Information Paper is aimed at energy and facilities managers, energy consultants and advisers.

ID08 BRE Digest DG498 Selecting Lighting Controls by Paul Littlefair - UPDATED EDITION

Published 24 February 2014   Price: £16.50 (£19.80 for soft copy) 

IHS BRE Press  ISBN 978-1-84806-365-5





Lighting controls can give important energy savings and their reasonable provision is required by Building Regulations whenever lighting work is carried out in buildings that are not dwellings. When choosing lighting controls, it is important to take into account the type of space, how it is used and the amount of daylight available.

 Find out what the common types of control and how to calculate energy savings.

It will be interest to building owners, designers, energy auditors, building services contractors and building control bodies.6-409-6

ID07 Understanding the choices for building controls

Published February 2014   Price: £16.50 (£18.60 for soft copy) 

IHS BRE Press  ISBN 978-1-84806-359-4

 

 

 

 

The control of energy in smaller buildings is generally poor, despite the availability of a range of tried and tested systems incorporating both mature and innovative technologies. 

The installation of heating, ventilation and air conditioning (HVAC) zone controls, optimising controllers for wet heating systems, and lighting controls are encouraged by the government. Financial support through the enhanced capital allowances (ECA) scheme and good practice guidance from the Carbon Trust is provided. Despite this, specifications are often limited to the minimum requirements; innovative technologies, such as pre-programmed packaged building energy management systems (BEMS) and demand control ventilation (DCV), are rarely applied. 

This Information Paper addresses the barriers to applying energy efficient control systems by providing simple explanations of innovative technology, what it can do, where and why it can and should be used - the pros and cons, and how to get to an effective solution in practice.

ID06 Operating BEMS - A practical guide to building energy management systems

Published February 2014   Price: £13.00 (£15.60 for soft copy) 

IHS BRE Press  ISBN 978-1-84806-360-0

 



Building energy management systems (BEMS) are often an integral part of a wider building management system (BMS), their purpose being to optimise the building’s energy use. These systems are commonplace in larger buildings and are rapidly becoming standard.

This has also been recognised by the industry, culminating in the publication of BS EN 15232:2012 (Energy performance of buildings – Impact of building automation, controls and building management).  This European Standard is aimed at the design of the system and not at how to maintain and operate it. The impact, in practical terms, is that the design of such systems is generally very good and commissioning is acceptable.

However, the understanding and operation of such systems at the user level is generally poor. As a result, the need to maintain these systems to realise the ongoing saving potential is not generally recognised by the end-user and/or the engineering services provider, which often means the systems are not maintained to the level required.

In addition, the settings are not reconsidered and revised when significant changes occur to either the building or how it is used.  There is therefore a need to provide practical advice to building users on how to operate these systems effectively and thereby realise potential energy savings.

The objective of this Information Paper is to bring together BRE’s wide-ranging knowledge and experience in energy surveys and auditing into a single publication.  This is not a comprehensive technical guide, but highlights the important issues that need to be considered and directs the reader to more detailed technical information where appropriate.

Guidance contained herein is applicable to:

energy and facility managers looking to employ energy consultants to complete energy audits and surveys – to understand the scope and context of the works energy consultants and advisers looking to maintain their professional expertise and to update their knowledge of the approach and techniques needed to comply with recent and imminent legislation and standards system and equipment suppliers looking to assess how their particular technology or service will support clients in meeting recent and imminent legislation and standards.

This publication follows the structure of BS EN 16247-1 and reviews its content. It is intended to put sufficient flesh on the bones of the standard to enable good-quality audits to be specified.

ID03 ENERGY MANAGEMENT IN THE BUILT ENVIRONMENT: A review of best practice

Published 17 January 2012  Price: £35.00 (£42.00 for soft copy) 

IHS BRE Press  ISBN 978-1-84806-235-1

 

 

  

A publication devised jointly by Building Research Establishment and ESTA to provide practical measures and advice to energy, facility and maintenance managers on how to manage energy.

A step-by-step approach to energy management is explained, together with the use of a matrix tool for implementing energy management initiatives within an organisation.

The tool can help identify areas for improvement, prioritise energy management activities and maximise benefits. Most of the examples are from the built environment but the principles can be employed in any organisation or industry sector.

The guidance is applicable by anyone responsible for energy management in an organisation, from board level to operational staff.
