As 1 April 2007 approaches and the transitional period for the implementation of the new Building Regulations comes to an end, advice and support on implementing low carbon buildings is at hand for both building professionals and their customers says Hugh Jones of the Carbon Trust.
Peter Walker
The technology for reducing carbon emissions can be more readily available then finance. Peter Walker explains how this dilemma can be resolved.
pool hall
The energy costs of the swimming pool hall at Oundle School in Northamptonshire have been halved following the installation of a ventilation heat-recovery system designed by Calorex heat pumps.
bsria
To meet the growing demand for testing the airtightness of buildings, as required by the latest Building Regulations for commercial buildings above 500 m2 and dwellings, BSRIA’s service now operates from four locations — Bracknell, Swansea, St Helens and Belfast.
training
Samantha McDonough, CIBSE’s director of policy, discusses the vital role that CIBSE register of low-carbon consultants has in realising the objectives of the latest Building Regulations.
space
A strong demand for air-source heat pumps designed principally for space/water heating is predicted by Space Air, which distributes Daikin products.
graphs
While high-efficiency motors and variable-speed drives have a role to play in reducing the energy used by pumps, system design is much more important. Roy Henderson explains.
daikin
Installers, specifiers and manufacturers in the building services industry must do more to educate their end-user customers on the benefits of installing energy efficient and cost effective equipment in their premises, according to Daikin Airconditioning UK Ltd.
heat pump
Dimplex has been appointed an approved supplier of ground-source heat pumps under the second phase of the DTI’s Low Carbon Buildings Programme. £50 million is available over the next 18 months to help fund the installation of ground-source heat pumps and other micro-generation technologies for schools, public-sector and not-for-profit buildings, as well as local-authority and housing-association housing projects.
Exploiting the capabilities of simulation software from the earliest stages of the design of a new headquarters for the Irish Office of Public Works in Eire has halved energy consumption compared with other possible designs.
chiller
Airedale’s OptiChill range of large-capacity, high-efficiency air-cooled screw chillers are said to break new ground in energy efficiency.Components are selected for optimum operating efficiency, so these chillers can achieve an EER of 3.0 or more at Eurovent conditions and ESEER values above 3.5 (for seasonal performance based on Eurovent’s part-load index).
In a campaign to reduce electricity consumption, Boots is working with utility-monitoring specialist Parasense to improve energy management in 500 shops.
     dimplex
Building on over 25 years’ experience in Europe, Dimplex has introduced its range of heat pumps into the UK. The company has been selected as one of only three approved suppliers of ground-source heat pumps for public-sector grants under Phase 2 of the DTI’s Low-Carbon-Buildings Programme.
panel
Applied Energy offers a design application service for the Stiebel Eltron range of solar systems for generating hot water that can be used to help supply central heating and domestic hot water. The service aims to maximise efficiency and ensure that the full benefits of solar thermal heating are realised through SAP and the latest Part L.These solar collectors exploit both visible and infra-red light from the Sun with a thermal efficiency of over 80%.
Toshiba
Contributing to the stunning restoration of an architect-designed pub refurbishment on the banks of the River Dee in Chester is air conditioning installed by local contractor Bostock Air Conditioning.
Hatfield
The efficiency of modern air conditioning and its ability to exploit renewable energy make it part of the solution to reducing carbon emissions — not part of the problem. Philip Ord explains.
heat pump
A variety of low-to-zero-carbon technologies and equipment to exploit renewable energy for domestic heating is available from Applied Energy with its Creda and Stiebel Eltron product ranges. The company also offers design and support services for specifiers, developers and installers.
Atlantic
Two oil-fired condensing boilers have been installed in a Grade 2 listed building in Yorkshire to provide space heating and domestic hot water. Supplied by Atlantic Boilers, they use outside air for combustion and achieve an annual efficiency of at least 92% and up to 99%. which is said to be 40% better than conventional modern boilers and up to 20% better than conventional condensing boilers. Flue-gas temperatures are always below 50°C, so low-cost plastic flues can be used.
Doncaster
Some 50 to 60% of the annual requirement for domestic hot water in a nursing home at Doncaster is met by a Vaillant solar systems — significantly reducing carbon emissions.
Sankey diagram
For some time, major boiler companies have been exploiting heat-pump technology to develop new approaches to heating. Now a major air-conditioning company has done the same — and produced assessments of the potential of this technology for reducing carbon-dioxide emissions.
Milennium point
Derek Duffill reflects on the role that building-management systems can play in saving energy and reducing a building’s carbon footprint.
valve
A reliable and cost-effective method of satisfying the boiler bypass requirements of Good Practice Guide 302 to Part L1 of the Building Regulations for England and Wales is provided by an automatic bypass valve from Honeywell.
calorex
Tony Barnes believes the British are hot on the heels of ground-source heat-pump technology.
priva
Priva Building Intelligence has eliminated the need for boilers and chillers in its new headquarters in The Netherlands by integrating an underground thermal storage system (UTES) into the design for the 8200 m2 building. Previous installations have shown that such a system can reduce energy costs by 40 to 80%.
viessmann
One of the first UK installations of a Viessmann Vitolig biomass boiler is in a house in Cheam.
EC Power
EC Power moves to boost take-up of small-scale CHP
BMW
A continuing programme of improvements by Honeywell Building Solutions (HBS) at BMW’s vehicle distribution centre at Thorne near Doncaster is aimed at saving energy and enhancing the environmental credentials of the centre. HBS used data from BMW and feedback from its 8-strong maintenance team on site to create a control solution to help identify and eliminate waste at the centre.
Wales
Mike Lamb considers how increasing awareness of the importance of renewable energy adds to the importance of underfloor heating.
Westcott
Keith Westcott argues that the current boom in demand for underfloor heating makes good engineering based design even more crucial to maximise comfort and efficiency.
Rehau
Graham Richardson explains the importance of controls in enabling underfloor heating to enable the heat generators that deliver hot water to operate at maximum efficiency.
LZC
Underfloor heating has been chosen for a ground-breaking zero-carbon house project in the Shetland Islands. The project aims to show how an holistic approach to renewable energy can eliminate household carbon emissions. The Osma underfloor heating system is supplied with hot water by an air-to-water heat pump, which also provides domestic hot water via a heat store.
electric
Electric underfloor heating mats from Creda are only 3 mm thick and can be used with any type of flooring — including ceramic tiles, carpet, laminate or wooden floors. They can used for new build or refurbishment projects in homes. Benefits include low capital cost and easy installation. They gently emit heat to provide an even, draught-free and warm environment. Temperatures are regulated by a wall-mounted multi-controlling thermostat that allows for 7-day programming.
heat pump
Using renewable energy can reduce carbon emissions and deliver savings on fuel bills. Bill McConnel explains how underfloor heating can reinforce these energy efficiencies.
Ingram
The capabilities of underfloor heating for delivering comfort using less energy than other forms of heating are increasingly being recognised — especially with the latest Building Regulations requiring new buildings to have a carbon footprint around 25% less than a similar building designed to the 2002 Building Regulations.
Carpets and underlay with a combined rating of 2.5 Tog can be used with underfloor heating without impairing its efficiency, according to tests carried out by the Underfloor Heating Manufacturers’ Association. The results are said to prove that the old maximum of 1.5 Tog is too low.
