hoval
Existing oil-fired boilers will already have space for fuel storage, so replacement with biomass boilers is an option. Hoval BioLyt wood-pellet boilers are available with outputs from 10 to 70 kW. They switch off and reignite automatically and can achieve an efficiency of up to 95%. To maintain efficiency, heating surfaces are self cleaning.

Out with the old . . .

Refurbishing or upgrading existing heating plant provides the opportunity to deliver very significant increases in efficiency but there are a number of factors that need to be taken into account. Kevin Stones takes a look at the key considerations.

Norwich Union
At the headquarters of Norwich Union in Norwich, the refurbishment of seven existing buildings to deliver new office accommodation has been made possible with active multi-service chilled beams incorporating a range of factory-fitted services.

Multi-service chilled beams enhance refurbishment opportunities

Multi-service chilled beams remove the need for suspended ceilings, resulting in greater room height and more usable space. But their benefits in refurbishment projects don’t stop there, as Terry Farthing explains.

RS
New lighting and controls has halved energy consumption for lighting in the RS Components warehouse at Corby.

RS Components takes dim view on high lighting costs

The quality of lighting has been significantly improved and energy costs halved in the main distribution centre of RS Components at Corby by upgrading from high-pressure sodium to Venture Lighting’s pulse-start metal-halide lamps and Ventronic dimming system.

lamps
By prolonging the life of lamps, lighting control reduces the problem of their disposal.

Making light of maintenance costs

There are more benefits to be gained from controlling lighting than energy savings. The reductions in maintenance costs can be even more important. Mark Andrew explains how good lighting control can help slash maintenance costs.

New lamps for old fittings

The benefits of modern fluorescent tubes can be exploited without having to replace lighting fittings using Save It Easy components from ECSL.

hotel
Cold though the waters of Loch Ness are, on which the Inchnacardoch Hotel stands, the is now shortage of hot water inside following the installation of an Andrews LGP storage water heater.

The hot-water system servicing a prestigious hotel overlooking Loch Ness has been has been upgraded with an Andrews Hi-Flo LPG-fired storage water heater. It supplies the 15 guest room in the Inchnacardoch Lodge Hotel, the kitchen and all the hotel’s domestic hot water.

GW
Standard-efficiency boilers could match the performance of condensing boilers in replacement projects — Graham Williamson.

Getting the best from replacement boilers

Despite the heating industry’s excellent response to Part L2 and L2a of the Building Regulations, which has seen the move towards high-efficiency boilers gather pace since April 2006, Graham Williamson argues that standard-efficiency appliances still have a major role to play in the non-domestic sector.

solatube
Lots of daylight introduced into the staff room at a school in Norfolk by two Solatubes has transformed this previously dreary space in a bright and attractive environment.

Brighter outlook for school in Norfolk

A windowless staff room in a Victorian school building has been transformed into a bright and attractive environment following the installation of two Solatube daylighting systems to replace flexible tubes that had been installed even though Solatube had been specified.

CBI calls for bursaries for science and engineering students at university

To encourage more students to study science and engineering, the Confederation of British Industry has proposed a bursary of £1000 a year per student. The suggestion has been made against the background of a decline over many years in the study of science, technology, engineering and mathematics (STEM) subjects. Its total cost is put at around £200 million a year.

kildare
Natural ventilation meets intelligent control — Opening windows to provide natural ventilation is a key part of the environmental strategy of the offices of Kildare County Council at Aras Chill Dara. Their operation is controlled by the building-management system in response to carbon-dioxide levels and temperature, with SE Controls’ OSO controllers opening and closing the windows. To provide occupants with individual control, the system is interfaced with the PC network — so that individual switches are not required on the walls by the windows.

Building the intelligent bridge to sustainability

Passive technology alone cannot meet sustainability objectives. Alison Nicholl explains why intelligence-based solutions are also needed.
