chilled beams
Integrated service modules from SAS are space saving and deliver air-conditioning more efficiently than fan-coil systems. This installation is at Imperial College in London.

The energy efficient approach to delivering comfort cooling

Chilled ceiling and beams deliver comfort cooling with 60 to 70% lower energy use than other systems, which is why John Staunton argues that this water-based approach cannot be ignored.

Demand-controlled ventilation

Monitoring carbon-dioxide levels in a building enables ventilation to be controlled according to occupancy and to maintain indoor air quality — efficiently. Bill McConnell examines the benefits that can be obtained.

vaillant
This Vaillant solar thermal installation on a barn conversion will meet over half of the hot-water demand for the building.

Barn conversion turns to the Sun

As part of the conversion of a barn in Pershore, Worcester, a Vaillant solar system has been installed to help meet the demand for domestic hot water. The family for which the conversion was being carried out consulted with Vale Heating, which specified installing a Vaillant solar auroTherm system to provide 50 to 60% of the hot-water requirement.

pie
Building services, with its demand for cooling and space heating, is one of the major users of motors

Embarking on an energy-efficiency drive

With today’s overriding concerns about energy efficiency, is the building services sector missing a great opportunity to make their buildings more efficient.

daikin
At the heart of a heat-recovery air-conditioning system serving a maternity unit in Poole is this Daikin 14 hp condensing unit.

Maternity unit enjoys the energy-saving benefits of heat-recovery air conditioning

Energy-efficient heating and cooling for a hospital in Poole is provided by a Daikin VRV heat-recovery air-conditioning system.

ecocooling
Originally designed with no cooling or ventilation, this outpatients area in an east-Midlands hospital is now kept comfortable by a combination of balanced ventilation and EcoCooling evaporative cooling units.

Evaporative cooling solves hospital over-heating

A low-energy approach to reducing temperatures in outpatient waiting areas in an east-Midlands hospital is provided by EcoCooling evaporative cooling used as part of a balanced-ventilation system. A typical EcoCooler rated at 30 kW can reduce electricity costs by over £2000 a year and carbon emissions by 10 t compared to an equivalent refrigeration-based system.

hoval
Using adiabatic cooling to cool outside air which, in turn, cools inside air via a plate heat exchanger is the key to this approach of delivering comfort cooling with a COP of up to seven. It also enables adiabatic cooling to be integrated with techniques such as direct expansion.

Advancing the art of adiabatic cooling

A fresh approach to adiabatic cooling can provide an ideal solution where new or additional comfort cooling is required. Chris Ree explains how.

passivent
Among a range of Passivent natural-ventilation equipment installed in a new primary school in Altrincham are Airscoop units in the main hall.

Simply delivering energy-efficient products as its contribution to reducing the threat of climate change was not enough for Sanyo, which has adopted the Think-Gaia concept to direct its future development.

Building-controls market tops out

The role of system installers in the market for controls and building-management systems is growing, according to figures compiled by the Building Controls Industry Association — but service and maintenance work shows a sharp decline.

seachange
A new SeaChange underfloor heating controller can provide individual control of up to six zones.

SeaChange controller can serve six underfloor heating zones

A new SeaChange controller for underfloor heating can provide independent temperature control of heating zones in underfloor heating schemes. This controller, from SC Controls, operates with a SeaChange control system to deliver a demand-based environment. This level of integration ensures boiler plant and associated heating pumps operate only when there is a demand from the heating zones.

cp
Small and compact, this presence detector from CP Electronics avoids the wasteful use of light – and also incorporates a photocell.

Presence detection avoids wasteful lighting

A ceiling-mounted presence detector that can be surface- or flush-mounted onto a British Standard switch box has been introduced by CP Electronics. The SPIR-F/C detector monitors the zone and switches on automatically when occupancy is detected and off a preset time after the area has been vacated. The time delay can be adjusted from 10 s to 30 min. If there is sufficient natural light, a built-in photocell keeps the lighting off.

Integration has to be the way forward

When the question, ‘Are integrated/open systems the smart move?’ was presented to a panel discussion at the recent conference of the Building Controls Industry Association David Kitching of Siemens Building Technologies was in his element in presenting a resounding ‘yes’.

ics
London’s tallest buildings for several years will incorporate a building-management system designed and installed by Integrated Control Systems to contribute towards halving energy consumption compared with similar buildings.

ICS contributes to energy efficiency in the City

Helping to halve the energy consumption of new buildings in the City of London compared with similar buildings is the installation of a £1.8 million shell-and-core building-management system by Integrated Control Systems. The project includes 201 Bishopsgate and the Broadgate Tower.

BSRIA starts eu.bac testing

Trend Control Systems has selected BSRIA to test its individual zone controllers as part of the process of applying for eu.bac certification. Only products that are tested by an authorised laboratory can now obtain this certification and carry the eu.bac mark. The mark is an expression of energy-efficient performance, and quality assurance, and Trend plans to be among the first in Europe to apply it to its controls.

Helping nature with effective control

Achieving the best results from a natural ventilation system requires optimal control of a number of parameters. John Fallon explains the importance of a fully integrated approach.

missing linkage
A missing linkage between a control valve and its actuator, as discovered when Darren Jones was working for a large pharmaceutical company in the south of England, is not the kind of fault that would readily be apparent from the supervisor of a building-management system.

The realities of running buildings efficiently

As an experienced energy manager, Darren Jones believes that too much faith is placed in the building-management system to achieve the efficient operation of building-services systems. He argues the need to get away from the central supervisor and find out what is actually happening in the building.

panels
There are two types of solar thermal collector — evacuated tubes (main picture) and flat plate collectors. Evacuated tube collectors are about 20% more efficient than flat plate.

Exploiting the opportunities for solar hot water

The UK has an ideal climate for solar heating, and consulting engineers are more involved than ever in harnessing this valuable natural resource, says Paul Jakeway.
