A method of controlling natural air movement to ventilate buildings is recognised by the Energy Technology and, therefore, qualifies for Enhanced Capital Allowances.

Display Energy Certificates for buildings are intended to stimulate reductions in their energy consumption. Lisa Wilkinson discusses the role of monitoring an targeting to improve the operational rating of buildings.

Before going for renewable-energy sources to improve a building’s energy certificate, make sure your building is ready first, says John Bailey.

Energy Performance Certificates for Buildings will not just happen from April. Hywel Davies explains how readers of Modern Building Services can become involved in assessing the energy performance of buildings and issuing certificates.

Hamworthy Heating now offers Roth solar panels as part of its renewables option for commercial heating and hot-water systems.

To help those involve in the industry to find their way around the building-certification process and likely future legislation, environmental-control specialist Mitsubishi Electric has produced a free, independent guide to Building Energy Ratings.

Underfloor heating and cooling, combined with ground-source heat pumps, are reducing energy consumption and carbon-dioxide emissions by 30 to 40% for the new £18 million headquarters of Gloucestershire Constabulary. This sustainable solution played a key role in this PFI project receiving a BREEAM excellent rating.

Since the installation of two ABB variable-speed drives at a block of managed business premises in Monmouthshire, the running cost of the air-handling unit has been reduced by over 70%. Costs have been reduced by over £6000 a year, and carbon-dioxide emissions reduced by 12 t a year.

Vaillant’s new auroTHERM plus VFK 990 flat-plate solar collectors can be connected in series in horizontal or vertical orientation to suit the available roof space. These collectors have a special anti-reflex coated toughened 4 mm-thick glass. The collector consists of an ultrasonically welded copper grid with a high selective absorber coating and 60 mm of rear and side insulation.

With buildings generating almost half of the UK’s carbon emissions, building services consultants have a unique role in both creating and assessing a low-carbon environment. Nygel Humphrey explains how energy-efficient ventilation can contribute to this vision.

Replacing two old cast-iron boilers with two Ultramax 381 gas-fired condensing boilers from MHS has reduced energy costs for a private golf and country club in Cornwall by 16%. The payback period for the China Fleet Country Club will be within 3.5 years.

Hoval’s SolKit is a highly efficient solar system for generating domestic hot water for commercial and residential applications. It comprises solar collectors with bracketry and flashing kits for on pitched roof, in-pitched roof, on flat roof or on the wall. The system also includes a stainless-steel cylinder, sophisticated plug-and-play digital-control system, pre-mixed heat-transfer fluid and all connections.

Hamworthy Heating has joined forces with Rural Energy to offer a comprehensive and practical solution to using biomass boilers.
