2004 June

past presidents
The Heating & Ventilating Contractors’ Association has seen its fair share of triumph and adversity in its first 100 years. Modern Building Services sought out some presidents who played key roles in a century of contracting to see if the lessons of the past could inform the future.
On the technical front, building services has changed more in the last 25 years than in the previous 75 years. Commerical and economic problems ,however, remain stubbornly persistent.
Can it really be as late as the 1960s before legislation for minimum standards of heating in offices, shops and factories was passed? How much longer might we have to wait for legislation on excessively high indoor temperatures?
Despite the economic difficulties of the 1930s and 1940s, building services grew in importance — and air conditioning was installed in a number of prestige buildings. Education and training needs received serious attention.
Nesbit
With new and developing technologies to provide better-serviced buildings came conflict between the traditional skills of plumbers and the new breed of heating engineer. It was the need for representing the special interests of contractors that led to the formation of the forerunner of the Heating & Ventilating Contractors’ Association.
HVCA @ 100

HVCA @ 100

01 June, 2004
The Heating & Ventilating Contractors’ Association is making much of its centenary in June, with a major centenary convention in Harrogate. The first president, David Nesbit, will be there (played by an actor). For the many, many people with deep roots in the building-services industry who will not be at this convention, our commemoration of the centenary of the HVCA will bring back memories and give an insight into this history leading up to building-services engineering as it is today. Our thanks to the CIBSE Heritage Group for making photographic material available from its archives and to HVCA for its support.
UPS
Having regularly experienced long power cuts lasting up to 48 h, mechanical, electrical and maintenance contractor Resource Environmental Services has tackled the problem by installing a standby power system from Scorpion Power Systems. The turnkey package includes generator, UPS, full electrical installation, testing and commissioning.
Turkish Embassy
Self-regulating electric floor heating in the Turkish Embassy in London is achieving energy savings in excess of 20% compared with an unregulated system.
University of Essex
The installation of 350 thermostatic radiator valves in student accommodation at the university of Essex has reduced gas consumption by 8% in the five months since they were installed. That equates to an energy saving of nearly £2000 in a full year.

Modular prefabrication based on wooden structures for one of the UK’s newest Travelodges at Leicester provided an ideal application for the use of Yorkshire Fittings’ XPress Copper range of plumbing. Because of the wooden structure, no hot work was permitted.
A relationship stretching back over 20 years between installer Air Conditioning Economics in Derby and Airedale International Air Conditioning has continued with the supply of an Ultima Compact chiller to maintain accurate temperatures in offices and laboratories of International Laboratory Services in Derby.
CHP project
Carbon emissions are being reduced by over 840 t a year following the installation of a CHP scheme serving some 5000 properties in Portsmouth, including hoses, bungalows and high- , medium- and low-rise blocks of flats. The Charles Dickens District Heating Scheme is also expected to reduce annual fuel bills by about £120 per household on the Buckland estate to the north of the city centre.
To help the industry respond to the recent 80% reduction in exposure limits to electromagnetic fields, BSRIA provides surveys of electromagnetic fields to assess current levels and make practical recommendations to solve problems. The National Radiation Protection Board says that the safety thresholds for exposure to power lines, mobile phones and radio transmitters should be reduced to bring Britain into line with international guidelines.
CIBSE has confirmed that its 2004 national conference will go ahead — despite the cancellation of the Clima Expo exhibition that was scheduled at the same time this Autumn. The new venue is the International Hotel, Marsh Wall, next to Canary Wharf in London. The dates are unchanged — 29 and 30 September.

Daikin has acquired one of the UK’s fastest-growing air-conditioning suppliers, MacQueen Air Conditioning.
Kathryn Nicholson
A chartered accountant employed by McQuay has won an award for her dedicated voluntary work on a community project in Northumberland.
A 25 to 30% improvement in the energy performance of buildings over present ratings can be expected when revised Building Regulations come into effect by the end of 2005, according to Alan Aldridge, executive director of the Energy Systems Trade Association. He was speaking at the London event of a series of nationwide seminars organised by ESTA ‘Keep your eye on the ball’.
Emap has acquired the 50% shareholding in Interbuild that was formerly held by Montgomery Exhibitions. Formal ownership starts on 7 July.
CIBSE has enlarged the scope for membership by being able to accept competent building-services engineers as corporate members without demanding that they meet the narrower requirements of the Engineering Council at the same time. The changes that the Privy Council has approved are in line with developments in other engineering institutions. Candidates for corporate membership will still be required to meet CIBSE’s own competence standards.
