2011 November

BRE has issued updated guidelines on ways to achieve good natural lighting in homes and non-domestic buildings. These guidelines are widely used by local authorities to help determine whether a new development blocks too much daylight and sunlight to existing properties nearby. This report supersedes 1991 guidelines and gives advice on site layout to achieve good sunlighting and daylighting — both within buildings and in the open spaces between them.

Thermal imaging

03 November, 2011

The thermal imaging of building fabric is covered in a new guide from BSRIA, which replaces the previous edition dating from 2002. It includes updates on Building Regulations, advances in camera technology and improved methods of analysing images. It aims to help people involved in constructing, owning and operating buildings with obtaining the thermal imaging they need and understanding of the information that can be obtained.

GASTEC at CRE Ltd (GaC), the independent testing, accreditation and training organisation, has launched a new ‘MCS Advisor’ training programme. GaC identified this critical gap in the training of MCS installers following extensive market research and the review of performance data from installed renewable-energy appliances across the UK. It appears that many consumers consider there is a disappointing gap between actual performance and their expectations — a case of over-promising and under-delivery blamed on retailers and installers.

Sirius Products, electrostatic precipitation, air filtration

Sirius Products has developed an electrostatic precipitator that sends almost zero waste to landfill throughout its entire lifecycle. The ESP has been specifically designed to remove up to 98% of grease, smoke and other airborne pollutants from commercial kitchen extracts.

A new facility to produce and store the Blackpool illuminations has its heating provided by radiant heating supplied by AmbiRad. Called Blackpool Lightworks, the 11 000 m2 building has been built to house £10 million-worth of fibre optics, laser and illumination exhibits. It also houses workshops, spray booths, storage and offices. A feature of the building is its high ceilings for the creation and testing of large exhibits and lighting pieces.

Schneider Electric’s own C Bus system has been used to provide a reliable and robust lighting-control solution for its expansive manufacturing and storage facility covering over 17 000 m2. This lighting-control solution combines controls, sensors and flexible user interfaces to provide automated control of lighting based on occupancy and ambient light levels.

A year on from upgrading its steam traps, Marston’s Brewery has saved £60 000 in energy and hot-water costs. The new equipment from Spirax Sarco prevents steam escaping into the brewer’s condensate-recovery systems and also improve the site’s environmental image by eliminating visible steam emissions.

Elta  Fans, FastlaneAHU

The ventilation requirements of a new £1.3 million dental clinic at Dunbar Hospital in Thurso are met by two air-handling units supplied by Fastlane Ventilation and two units by Elta Fans. The order was secured on the basis of price and service for the clinic, which will cater for about 6000 patients. This scheme is part of a £5.6 million injection to improve NHS provision in Thurso, Dingwall, Oban and Campbeltown.

Climaventa, chiller, air conditioning

The ability of Climaveneta UK (formerly Walter Meier) to disassemble chillers and reassemble them on site proved invaluable in replacing an aging chiller at Hertford Magistrates Court. The chilled-water system provides comfort cooling, and the previous aging chiller was proving unreliable and inefficient. Contractor CCS Air Conditioning was appointed to install a new chillers.

Baxi SenerTec, CHP

Annual cost savings of over £2000 are expected following the installation of a Dachs mini-CHP unit in a residential property in London. Installed in a garage, together with a condenser and buffer vessel, the unit generates up to 15.5 kW of heat, which feeds into a 750 l buffer vessel connected to the heating circuit, also served by two condensing boilers. The circuit serves space heating for this substantial Victorian detached house and indoor swimming pool in an extension, which provides a constant demand for heat.
