2007 March

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.
EC Power
EC Power moves to boost take-up of small-scale CHP
viessmann
One of the first UK installations of a Viessmann Vitolig biomass boiler is in a house in Cheam.
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%.
calorex
Tony Barnes believes the British are hot on the heels of ground-source heat-pump technology.
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.
Milennium point
Derek Duffill reflects on the role that building-management systems can play in saving energy and reducing a building’s carbon footprint.
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.
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.
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.
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.
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.
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.
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%.
     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.
In a campaign to reduce electricity consumption, Boots is working with utility-monitoring specialist Parasense to improve energy management in 500 shops.
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).
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.
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.
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.
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.
space
A strong demand for air-source heat pumps designed principally for space/water heating is predicted by Space Air, which distributes Daikin products.
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.
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.
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.
Peter Walker
The technology for reducing carbon emissions can be more readily available then finance. Peter Walker explains how this dilemma can be resolved.
parkersell
Both maintenance and running costs of lighting at Blue Diamond Engineering in County Durham have been reduced following the installation of a new lighting system by Parkersell. The project qualified for a Action Energy Loan from the Carbon Trust; this scheme is targeted at SMEs in England and Wales and offers interest-free loans that are repayable over a negotiable period.
Riello
The heating and hot-water systems for Romford’s new £261 million Queen’s Hospital are powered by four Riello industrial burners with a capacity of 6 MW. These Monobloc dual-fuel burners are installed on 4.1 MW steel hot-water boilers. Riello also supplied four gas boosters.
ICS
The 2012 Olympic Games in London has already generated business for Integrated Controls Systems. The company has won the fast-track contract to design and install the controls for offices being used by the London Development Agency, the regeneration agency laying the foundations for the games.
Oventrop
10 years ago, Newcastle City Council began installing Oventrop Hydromat differential-pressure regulators in dwellings on its Byker estate to facilitate hydronic balancing and eliminate system noise. The valves are said to have given trouble-free operation ever since.
Cast iron
Boilers at the University of the West of England in Bristol are being replaced with Hamworthy Purewell VariHeat condensing boilers with cast-iron sections as part of a programme of upgrading plantrooms. Four of six plantrooms have been upgraded — and energy savings are already apparent.
Fife
A wireless analogue fire-detection system is providing temporary protection for the outpatients clinics at a hospital in Scotland while the clinics are being refurbished.
Energy-efficient air conditioning for the latest Abode hotel in the UK, in Glasgow, is provided by a Mitsubishi Electric City Multi system with units in bedrooms activated by the door entry system.
Astrium
Precise environmental control for the production of £multi-million satellites at EADS Astrium is controlled by a Cylon BMS — along with lighting, ventilation, air conditioning and heating throughout the entire site.
Breezair
With temperatures in the cutting area of BLP UK, a volume manufacturer of MDF wrapped profiles and membrane press cabinet doors, exceeding an ambient temperature of 23°C by 15 K, industrial heating and cooling company Air Plants recommending a Breezair evaporative cooler to improve thermal comfort.
2012
Potential stars of the 2012 Olympic Games in London, along with university students and local school children, are already taking advantage of the flagship £7 million indoor sports facility at Brunel University. Their performance is matched by the Nor-Ray-Vac continuous radiant-tube heating systems from Ambi-Rad.
Daikin
Two penthouses and 32 apartments in Baltimore House, part of the Battersea Reach residential and commercial development by St George Plc, include Daikin VRV heat-recovery air conditioning among their numerous facilities and fittings. The systems were installed by Daikin D1 installer Air Cool Engineering Systems.
