Millenniium Point
Exploiting the potential of the integrated control system in Millennium Point in Birmingham reduced energy costs by 12% in just 18 months — setting an example for other buildings to follow.

The future’s bright, so dim those lights

The chronic lack of a long-term vision to tackle energy use means domestic buildings could soon pull away from industrial and commercial equivalents. The BMS industry must stop thinking in the short-term and start shouting about the impact it can make for decades to come, according to RICHARD STROD.

Priva
New touchscreens from Priva Building Intelligence provide high-resolution graphical displays that can be customised.

Delivering the intelligent building

Among the many benefits of intelligent, or integrated, buildings is a lower first cost. IAN STORRAR has the full story.

hoval
The capabilities of modern condensing boilers were fully exploited at Braintree college in Essex when three cast-iron sectional boilers were replaced with three Hoval Ultragas downward-firing condensing boilers, each rated at 500 kW. The greater efficiency of the new boilers achieves fuel savings of around 40%. In addition, pipework is simpler and fewer circuit pumps are required.

Reducing the cost of boiler operation

In comparing the life-cycle costs of boilers, combustion efficiencies are only part of the equation. KEVIN STONES takes an holistic view.

boiler
Unless system design and controls are integrated, condensing boilers such as Ideal Boilers’ Imax Xtra are likely to be only slightly more efficient than a standard boiler.

New boilers for old

Changes to Building Regulations have made the move towards condensing technology for commercial applications inevitable, GRAHAM WILLIAMSON discusses the issues affecting specifiers and identifies what they need to know when considering a condensing boiler in a replacement application.

cascade
Modular boiler systems can be finely tuned to suit any application. This is a selection of Vaillant ecoMAX boilers.

mail box
Lighting is an integral part of the ‘shop-front’ concept of the BBC Mailbox in Birmingham, which enables visitors to see into the radio studios, the editing suites, the drama studio and TV studio stacked on one side of the entrance. On the other side at the upper level, the space flows into the open-plan offices. In areas with low ceiling heights, a custom recessed solution is used. In the double-height space, an integrated direct/indirect solution is used. The project has won a Lighting Design Award

Moving beyond indifferent lighting

PROF. PETER BOYCE explores why so much lighting in commercial buildings in the UK is indifferent and what can be done about it.

cooling tower
Except for small air-conditioning installations, heat rejection via cooling towers is more efficient, takes up less space and has an overall lower life-cycle cost than dry coolers. Energy savings of up to 30% are consistently possible.

Why cooling towers need joined-up Government

Different Government departments have very different perspectives on the use of cooling towers for rejecting heat from air-conditioning systems. ROBERT MacLEOD-SMITH gives his perspective.

Greg Davies

The lessons of the Barrow LD outbreak

An expert witness in the recent re-trial of Gillian Beckingham, GREG DAVIS, considers the lessons needing to be learnt from this landmark case.

underfloor heating
By using the floor as a large heat emitter with a low surface temperature, underfloor heating works effectively with low flow temperatures — enabling the energy-efficiency benefits of condensing boilers and heat pumps to be fully exploited.

Pushing Part L under the floor

Underfloor heating has always been a highly effective method of delivering comfort, especially in large spaces. Changes in the last two editions of the Building Regulations have so improved its cost basis that the benefits can be more widely enjoyed.

Ozone layer shows steady recovery

The recovery of the ozone layer in the stratosphere is so well established that it should be restored to 1980 levels by the middle of the century. Eun-Su Yang of the Georgia Institute of Technology says that 25 years of data confirm that the Montreal Protocol of 1987 and subsequent regulations have prevented further depletion of the ozone layer. Scientists agree that the thinning of the ozone layer stopped in 1997.
