Building-services contractor Briggs & Forrester has been awarded a £1 million fit-out contract by Marriott Construction on behalf of client Delloite & Touch in Milton Keynes. The fit-out is part of the Pinnacle Project, a 23 000 m2 development due to be completed in June 2009. The building is serviced from the Milton Keynes CHP infrastructure and will achieve a BREEAM ‘excellent’ rating.
Integrated Environmental Solutions (IES) and Bureau Veritas claim the lodgement of the first dynamic-simulation non-dwelling Energy Performance Certificate in the UK.
Nu-Heat has added solar thermal technology to its one-stop shop of renewables solutions for house builders. The others are heat pumps and underfloor heating. There are air- and ground-source heat pumps and versions that can extract energy from exhaust air.
Heat-pump manufacturer Dimplex has welcomed an amendment to the technical guidance for the ‘Code for Sustainable homes’ by DCLG (Department of Communities & Local Government) that recognises the energy-efficiency and carbon-saving benefits of heat pumps.
Dimplex has launched a 3-day training course on ground-source products following the success of its accredited installer training scheme for air-source heat pumps.
The new Furnival building at Sheffield Hallam University has its heating provided by ground-source heat pumps supplied and installed by Danfoss Heat Pumps UK, formerly ECO Heat Pumps in Sheffield.

Sustainability in the park

Low-impact environmental control of the new pavilion in Reigate’s Priory Park is achieved by a ground-source heating pump, natural ventilation, solar reflecting glazing and a highly insulated roof to reduce solar gain.
The City of York is trialling Vaillant’s solar DHW system in a property in the village of Wheldrake to the south east of York, which is expected to halve the cost of DHW. British Gas Housing Services Group is installing the auroTHERM solar panels, an ecoTEC plus condensing system boiler and a 200 litre auroSTOR cylinder.
Carrier RentalXpress, the portable air-conditioning hire company in the London region, is to continue to plant a tree on behalf of customers which hire a unit for 12 weeks to offset their carbon costs, using the services of the Woodland Trust.

Scorpion launches CHP

08 September, 2008
Scorpion Power Systems has launched a range of CHP systems. PowerTherm is unique to the European market. Its engine technology gives 85.5% package efficiency with thermal recovery.
The best way for the building-services sector to tackle climate change is to focus on the obvious, says HVCA president Gareth Vaughan.
A ‘solar chimney’ system designed by Levolux drives ventilation in a new building at Lancaster University to prevent the build up of heat.
Mitsubishi Electric is highlighting the future of residential heating to installers and consumers with a new web site dedicated to its Ecodan award-winning low-carbon heating system designed specifically for the UK residential sector.
The installation of a solar thermal array at a school in Worle, Weston-Super-Mare, is expected to deliver CO2 savings of over 41 t a year. Dalkia designed and installed the system at St Martin’s Junior School as part of its ongoing work to reduce energy costs for schools in North Somerset.
Hoval’s CombiSol versatile thermal storage vessel enables various renewable and conventional heat sources to be easily combined and controlled effectively in a single system for space heating and domestic hot water. For example, solar heating can be combined with a condensing boiler to make maximum use of available solar energy, supplemented by the condensing boiler.
Homes in a world of climate change will have to use little or no energy while still maintaining a stable internal environment, as Jeff Culp explains.
Mitsubishi Electric’s headquarters at Hatfield is well visited by those looking for ways to reduce energy consumption and carbon emissions. The company’s own facilities manager, James Hobson, gives an insight into what can be seen — and takes readers behind the scenes to show how green ambition is matched with operating reality.
A 200 kW packaged air-source heat pump is providing the heating for a new serviced office building of Arena Business Centre at Poole. It offers 16 mezzanine studios ranging from 60 to 130 m2, and Arena was looking for a heating solution that would be cost effective and efficient, with low carbon emissions.
A Danfoss heat pump has been installed to replace oil-fired boiler plant at Woolfardisworthy (pronounced Woolsery) sports and community hall in Devon; the oil-fired plant has been retained to provide back-up in extreme conditions.
Calor gas is being use to power the National Trust’s first LPG CHP unit. It is in Cornwall at Trelissick Garden near Feock. The decision to introduce a low-carbon heating solution was made when a project was commissioned to extend and refit catering facilities at the site.
The CHP installation serving a housing development in Newcastle is reckoned to be the most efficient in the UK and the second best in Europe, according to Baxi-SenerTec, which presented the DACHS Award to housing company Places for People for its outstanding contribution to the development of sustainable housing.
Stephen Matthews, Chief Executive of CIBSE, argues that building-services engineers are part of a very small number of people that can really do anything about climate change.
Monodraught has been awarded an annual contract to supply and install its SunPipe natural-lighting systems and controls in buildings throughout the Environment Agency’s southern region, which includes Kent, Sussex, Hampshire and the Isle of Wight.
Adapting to climate change and mitigating its effects are at the heart of the Government’s sustainability strategy. Ant Wilson of Faber Maunsell considers the opportunities for building services engineers.
Ideal Boilers has added a 100 kW-output model to its Imax W range of wall-hung condensing boilers. To achieve the higher output, Ideal has refined the operation of the 80 kW version and created, in the same casing, the W100.
Following a successful trial of Vaillant’s VRC 630 boiler management system in the Knights Court sheltered-Housing scheme in Ventnor, South Wight Housing Association is considering installing further systems and communal heating in other sheltered-housing schemes.
Buderus has added a new wall-mounted boiler to its GB162 range. The new model has an output of 65 kW and joins the existing 80 and 100 kW models.
