Field
The 2006 Building Regulations present new challenges and opportunities for building-services engineers. JOHN FIELD is chairman of the Carbon Task Group of the Chartered Institution of Building Services Engineers and outlines their scope.
Taconova
Multi-apartment buildings and multi-storey flats need a centralised approach to energy-efficient plant and exploiting renewable energy, while still permitting individual control and metering for each dwelling. JOHN COOPER explains how this could be achieved.
Commissioning
With the growing use of variable-speed pumps comes the demise of proportional balancing. DUNCAN SELBY discusses this new world of commissioning.
Lights
The Government’s long awaited changes to Part L of the Building Regulations will set more onerous limits on the energy efficiency of lighting in domestic and non-domestic buildings. Just what’s involved is explained by HUGH KING.

The role of the Carbon Trust

The statistics of carbon emissions from buildings show just why the forthcoming Building Regulations are so timely.DR GARRY FELGATE explains how the Carbon Trust can help

Getting to grips with Part L

19 February, 2006
ANT WILSON of FaberMaunsell outlines the effect of energy-efficiency issues in the new Building Regulations for building-services engineers
Microgen Energy and Dutch boiler manufacturer are working together to commercialise an alternative to the traditional heating boiler. The microCHP appliance produces electricity and heat and could achieve energy savings of 25% for an average household. Remeha is represented in the UK by Broag.

Developing tactics

19 February, 2006
IAN ADAMS offers advice on how building services contractors, facilities managers and building owners can take a tactical approach in preparation for the introduction of the new Building Regulations.
Rinnai
To enable old, balanced-flue heating systems to be replaced with its powered-flue units, Rinnai UK has developed a flue-conversion kit.
SE
A natural-ventilation system from SE Controls has been specified for the Jubilee Library in Brighton. It has been designed by architects Bennetts Associates with Lomax Cassidy & Edwards as part of a £45-million scheme to transform a run-down area in the heart of Brighton with the creation of a new square, hotel, residential, retail and leisure buildings. The library itself has been designed to represent the future of public libraries.
Velta
Renewable energy from an underground aquifer serves an underfloor heating/cooling system in a recently completed school project in Holland. The Velta Contec system serves an area of 14 600 m2 in the Harlemmermeer Lyceum at Hoofddorp near Rotterdam.
Tesco
As part of its continuous drive to save energy, Tesco has incorporated rooflights, Sunpipes and a wind turbine at its new store at Diss in Norfolk. Airtightness services are being provided by BSRIA as part of continuing collaboration for over 13 years to achieve airtightness specifications way below those required by the Building Regulations.
Simmtronic
Simmtronic has supplied the fully addressable digital lighting-controls system for a new corporate office building on the new Spinningfields development in Manchester. Due for completion in March, 2 Hardman Street is an 8-storey building offering 13 300 m2 of office space and a basement car park.
HCM4
The HCM4 heat-calculating meter from Meters UK uses digital high-accuracy sensors (DHAS) to measure pipe temperature, avoiding the problems associated with platinum-resistance sensors and their complex installation requirements. DHAS sensors can be strapped onto pipes, rather than placed in designated pipework pockets.
Dimplex

Electric heating meets Part L

19 February, 2006
Against the background of the forthcoming Building Regulations, Dimplex has enhanced its approach to electric space heating to achieve carbon savings of up to 10% over conventional off-peak heaters.
Eurex
Packaged ventilation units from Eurex Energy incorporate a thermal wheel to exchange energy between the two air streams. There are three models in the RotOvent series, offering airflows from 10 to 180 l/s.
Ecocooling
EcoCooling has added side- and top-discharge evaporative coolers to its ECP range. They are designed for the commercial and industrial market to provide a simple, safe and low-cost cooling for people and processes.
Biddle
Biddle has enhanced the design of its Forceflow fan-convector heaters to operate with lower water temperatures — such as those delivered by condensing boilers.
Guildford
Sophisticated lighting-management and control systems from Ex-Or were specified for the showcase 2-storey extension to the learning resource centre of Guildford College of Law.
Phase 3 of the London Bioscience Innovation Centre, comprising 23 new office suites with adjoining laboratories, are fully air conditioned by five Daikin VRVII heat-recovery systems.
t-mac
An Internet-based approach to using existing instrumentation as part of remote management for energy monitoring and plant maintenance is offered by t-mac Technologies.
Breezair
Excessive indoor temperatures in the group head office of Garden & Leisure have been brought under control by installing a Breezair evaporative air cooler from Seeley International.
beam
Integrated service modules based on chilled ceilings have the potential to transform building design and project management. explains. ANDREW JACKSON.
Module
Maximising the energy-saving potential of variable-speed pumping systems in air-conditioning systems using fan-coil units demands action up close — says LARS FABRICUS.
test room
With the environment in which they are installed having a significant effect on the performance of chilled ceilings and beams, WILLIAM BOOTH explains the benefits of mock-up testing.
Carrier
Carrier’s quietest fan-coil unit to date is the Atmosphera, designed for concealing above ceilings.
Frenger
Frenger has supplied multi-service chilled beams for Saffron House in London that are just 140 mm deep. This listed building has minimal slab-to-slab height. As a speculative office development, it required exceptional heating and cooling capacities from the shallowest possible depth.
Prison
Part of the transformation of a former prison into a luxury Malmaison Hotel includes the installation of 77 chilled beams to convert the former cells of A-Wing t Oxford Castle into opulent bedrooms. Trox (UK) supplied these passive beams in a contract worth £100 000 and customised their design to blend in with their surroundings. Trox also supplied a range of fan-coil units, attenuators and grilles for the project.
Trox
Trox (UK) has invested £40 000 in a new facility to test fan-coil units. to the requirements of BS 4856 Part 1 1972.
Actionair
Actionair fan-coil units with DC electronically commutated motors have been used in the major refurbishment of two former MoD buildings near Bath to provide a new headquarters for Helphire Group, which specialises in replacement transport and other insurance-related services for motorists. The use of these motors can reduce power consumption by up to 40%, suiting them to low-energy environmental control. The heat gain from the fan motors is reduced by two-thirds.
Brentford
Fan-coil units with electronically commutated fan motors are being supplied by Smiths Environmental for Berkeley First’s Paragon development in Brentford. The 240 units will be installed by Star Mechanical & Electrical Services to provide air conditioning in the academic block, an 11-storey building which will become the new home of Thames Valley University’s faculty of health and human science this autumn.
Montluel
The opening of a state-of-the-art demonstration facility for fan-coil units enables customers to witness performance testing before a building is built. Virtually any building characteristics can be created. A wide range of windows, flooring and ceilings are held on site at Montluel in France, and thermal loads, outdoor and ambient temperatures, and the effects of solar heat gain can be replicated and varied at will.
