Although the capability to deliver intelligent buildings exists, the uncertainty of clients presents barriers to their acceptance. ALISON NICHOLL advises how to break down those barriers.
Sontay, which specialises in control peripheral products, has introduced online tracking of orders, an auto-update initiative to improve project management and information flow for customers and an enhanced web site.

ICS makes it five

24 September, 2006
Five buildings in Longford Centre development being built at Feltham in Middlesex are having control systems installed by Integrated Control Systems in a £100 000 contract.
Singapore Management University has used Echelon LonWorks technology in its new city campus as the foundation for its state-of-the-art intelligent building-management system. Multiple building-automation sub-systems are integrated to enable the university to significantly reduce energy consumption and costs and increase student comfort.
Achieving intelligent buildings requires the infrastructure to enable systems to communicate with one another and systems that can communicate. Integrated Systems is the key to the future of intelligent buildings. JULIAN JOWITT and BILL McCONNELLL explain how this is being made possible for air conditioning.
Total integration of building systems in the £330 million Westfield Shopping Centre development in Derby is being achieved using Honeywell’s Enterprise Building Integrator (EBI) interface. It is bringing together building-management and life-safety systems, along with security and access control.
Existing network infrastructure can be used by Merlin Gerin’s PowerLogic EGX400 Ethernet gateway to provide direct access to utility consumption and other energy-management information. It is operated via a web browser.
Millenniium Point
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.
In response to growing demand for interoperability and open systems, Priva Building Intelligence has released an update of its Top Control software, TC 6.0. This new software supports many more protocols and standards. It is compatible with XML, BACnet, Echelon/LonMark, KNX/EIB, ModBus, M-bus, ODBC, SQL and OPC.
The first meeting of the recently formed Intelligent Buildings Group of the Chartered Institution of Building Services Engineers is on 19 October at the Royal Society in London.

Improving energy management

20 September, 2006
Tailored solutions for intelligent metering, energy monitoring, remote data retrieval using automatic meter reading from PRI provide the information required to help control the use of energy and its associated costs.

Among the many benefits of intelligent, or integrated, buildings is a lower first cost. IAN STORRAR has the full story.
In comparing the life-cycle costs of boilers, combustion efficiencies are only part of the equation. KEVIN STONES takes an holistic view.

New boilers for old

19 September, 2006
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.
It has been clear for some years that the UK commercial boiler market has far more potential than the number of installations taking place each year indicate. JOHN BAILEY believes that its prospects have never been better.
The efficiency of boiler plant serving a housing development in Newcastle has been more than doubled following the replacement of the old plant with a system comprising two Ideal Super Plus boilers and two Imax Plus appliances on the one system. It provides 1530 kW of heat at an average efficiency of 95%, compared with 34% before.
Glow-worm’s Flexicon cx boiler is said to be the only high-efficiency combi on the UK market with a direct rear-flue option and small enough to be fitted inside a kitchen wall cupboard.
Vokera’s Condexa Pro range of wall-hung condensing boilers have three circuits for domestic hot water, high-temperature heating and low-temperature heating such as underfloor.
Vokera has extended its Autostop control to prevent domestic boilers being used for more than 12 months without being serviced to its Mynute HE range of high-efficiency system boilers and the new Unica HE combi range.
Stokvis Energy Systems has minimised emissions of NOx, CO and CO2 from its recently expanded Econoflame range of boilers by incorporating pre-mix burners, multiple-pass heat exchangers and the latest electronic controls.
PETE MILLS comments on the latest changes to Part L and their effects on commercial boiler specification, with particular reference to the application of controls in refurbishment projects.
Domestic hot water for homes with up to five bathrooms in a development in Salford is provided by packaged equipment specially designed and made by Elson. The development at Broughton Green is a partnership of the City of Salford and Taylor Woodrow, with the houses and apartments for sale. Heating and plumbing contractor George Birchall of Stoke worked with Elson to provide a prefabricated solution for the key parts of the system.
Dimplex has expanded its popular SU and SUTP ranges of unvented storage water heaters with the introduction of a larger storage vessel. These ranges are now available in sizes from a compact undersink 7 litres to a mid-range 75 litres.
Baxi Commercial boilers are included in the Energy Technology List, so that they qualify for Enhanced Capital Allowances. All the company’s commercial condensing boilers appear on the list.
Steve Hills
The latest Building Regulations emphasise the importance of commissioning in creating a heating system that is compliant with the regulations, energy efficient and cost effective. STEVE HILLS says that unless commissioning is completed correctly, the chances are the system will not be performing to its design specification.
All boilers are Charterhouse School are progressively being replaced with modern and more efficient systems from Clyde Energy Solutions.

Andrews Water Heating has developed a packaged approach to applying solar energy to the commercial water-heating market.

Hot water is being generated at an efficiency of up to 96% (net) for poultry company Moy Park Ltd at its factory in Derbyshire by a Lochinvar installation. The equipment comprises a Power-fin gas-fired water heater and an LST 250 storage tank with a capacity of 115 litres to provide a hot-water supply for the factory’s washdown facility.
