certificate
Do you know your EPCs from your DECs? John Fallon unravels the jargon and outlines the two new types of certificates, when they apply and their significance.
passivent
A method of controlling natural air movement to ventilate buildings is recognised by the Energy Technology and, therefore, qualifies for Enhanced Capital Allowances.

It’s easy to get greener

12 February, 2008
Display Energy Certificates for buildings are intended to stimulate reductions in their energy consumption. Lisa Wilkinson discusses the role of monitoring an targeting to improve the operational rating of buildings.
sun bathing
Before going for renewable-energy sources to improve a building’s energy certificate, make sure your building is ready first, says John Bailey.
Hywel
Energy Performance Certificates for Buildings will not just happen from April. Hywel Davies explains how readers of Modern Building Services can become involved in assessing the energy performance of buildings and issuing certificates.
Roth
Hamworthy Heating now offers Roth solar panels as part of its renewables option for commercial heating and hot-water systems.
Mitsubishi
To help those involve in the industry to find their way around the building-certification process and likely future legislation, environmental-control specialist Mitsubishi Electric has produced a free, independent guide to Building Energy Ratings.
Warmafloor
Underfloor heating and cooling, combined with ground-source heat pumps, are reducing energy consumption and carbon-dioxide emissions by 30 to 40% for the new £18 million headquarters of Gloucestershire Constabulary. This sustainable solution played a key role in this PFI project receiving a BREEAM excellent rating.
ABB
Since the installation of two ABB variable-speed drives at a block of managed business premises in Monmouthshire, the running cost of the air-handling unit has been reduced by over 70%. Costs have been reduced by over £6000 a year, and carbon-dioxide emissions reduced by 12 t a year.
Vaillant
Vaillant’s new auroTHERM plus VFK 990 flat-plate solar collectors can be connected in series in horizontal or vertical orientation to suit the available roof space. These collectors have a special anti-reflex coated toughened 4 mm-thick glass. The collector consists of an ultrasonically welded copper grid with a high selective absorber coating and 60 mm of rear and side insulation.
Vent-Axia
With buildings generating almost half of the UK’s carbon emissions, building services consultants have a unique role in both creating and assessing a low-carbon environment. Nygel Humphrey explains how energy-efficient ventilation can contribute to this vision.
MHS
Replacing two old cast-iron boilers with two Ultramax 381 gas-fired condensing boilers from MHS has reduced energy costs for a private golf and country club in Cornwall by 16%. The payback period for the China Fleet Country Club will be within 3.5 years.
Hoval
Hoval’s SolKit is a highly efficient solar system for generating domestic hot water for commercial and residential applications. It comprises solar collectors with bracketry and flashing kits for on pitched roof, in-pitched roof, on flat roof or on the wall. The system also includes a stainless-steel cylinder, sophisticated plug-and-play digital-control system, pre-mixed heat-transfer fluid and all connections.
Hamworthy
Hamworthy Heating has joined forces with Rural Energy to offer a comprehensive and practical solution to using biomass boilers.
Chris Monson explains the philosophy behind a European-wide scheme for certifying the performance of building controls.
enocean
By eliminating wiring costs, wireless sensors can increase the scope and flexibility of building-management systems — especially if they do not need batteries. Armin Ander explains.
liftstore
Liftstore’s CMS Anywhere software monitors the performance of lifts in a building and provides alerts to potential problems and breakdowns.
bacnet
The BACnet protocol for building systems does not impose a cost premium for achieving open functionality. Steve Loughney explains.
David Epps offers a perspective on building controls that not only deliver balance-sheet value but that help companies deliver on their HSE and CSR policies.
Honeywell
Honeywell equipment meets the control requirements of the new Cotswold Water Park Four Pillars Hotel in Gloucestershire. This hotel has 220 guest bedrooms, a range of light and airy conference, banqueting and meeting rooms, gymnasium, lakeside restaurant and 10 separate 2-bedroom suites.
Helvar
The first project in the world to use Helvar’s Digidim router for controlling lighting is the total refurbishment of the landmark Blekholmen premises in Stockholm, taking DALI (Digital Addressable Lighting Interface) to a new level.
Smile
Honeywell’s Smile controller provides weather-compensated heating control in buildings that are too small for a building-management system but too large for domestic-type controls. It provides similar capabilities to the Honeywell Aquatrol 2000, which has provided weather-compensated heating control for many years.
Priva
Keep Keen Controls has installed a control system from Priva Building Intelligence at the new £32 million Keepmoat Stadium in Doncaster. The controls design included interfacing with 150 Mitsubishi split air-conditioning systems.
PIR
To controlled lighting in little-visited areas of its self-storage warehouse in Bridgwater, UK Storage has installed Danlers PIR occupancy switches.
eu.bac
Design RXC controllers from Siemens Building Technologies for terminal units are among the first devices to achieve certification and be allowed to use the eu.bac logo (see page 33 for more information on eu.bac). This accreditation proves that these controllers provide energy-efficient control and can be a major factor in reducing a building’s carbon footprint.
Terracotta warrior
The current Terracotta Army exhibition in the British Museum is the largest exhibition of this archaeological discovery outside of China itself — and necessitated the provision of a tightly controlled environment.
