lBUILDING TECHNOLOGY THERMIE PROGRAMME: promotion of energy technology in Europe EDITORIAL


New JOULE - THERMIE The new THERMIE Programme (1995/98) is part of the 4th European Framework Programme for Research and Technological Development. The joint "JOULE - THERMIE" programme will consist of actions in research and development (JOULE) and in demonstration (THERMIE) in the field of Non-Nuclear Energies. The total budget for the four-year period is approximately 1,000 MECU, of which 530 MECU will be allocated to THERMIE. The first call for proposals was launched on December 15, 1994. The closing date for demonstration project proposals is 24 March 1995. While the principal objectives of THERMIE remain as before there will be some changes in focus under the new programme. For information about the Call for Proposals contact W.Folkertsma, DGXVII, Fax +32.2 295 0138/39/40.

GREEN BUILDING IN OLD DUBLIN The new 'Green Building' in Dublin's Temple Bar is archetypal in that a mixed-use building (shops, offices and apartments) for a 26m by 11m infill site on a narrow street is a common design problem in older towns and cities. It is prototypical in that it expresses an environmental philosophy suited to the 21st century and tries to do so in a commercially viable manner. Working to a tight 'fast-track' schedule for both design and construction phases meant that compromises had to be made. For example, no recycled aggregate could be found locally for the concrete and it was not possible to use re-cycled copper for the roof as originally envisaged. But the building incorporates a range of 'green' features in the context of an aesthetically satisfying solution.


The concrete structure and walls of dense concrete block, highly insulated externally with rockwool insulation and finished with plaster render, provide high thermal mass. Windows are double-glazed, 'low-e' and argon filled.

Building Technology looks at low-energy designs for offices in Cologne and Sussex, a 'green' building in Dublin, and two daylit training schools in the Loire Region of France.

A well has been sunk 150m into granite to extract dry ground heat. Water pumped through the well transfers its heat, via a heat pump, to water stored in a thermal reservoir. This in turn is pumped through coils embedded in the floor slabs to provide 100% of space heating.

courtyard has a fully-openable glazed roof and, classed as an external space, has non-fire rated windows opening into it. In the Winter air at roof level is heated by the sun, mixed with fresh air, and recirculated to the base of the courtyard from where it rises through the open windows to ventilate the occupied spaces. A pool at basement level humidifies the air and provides 'white noise', while at the upper levels of the courtyard, where high light levels permit smaller windows, extensive planting reoxygenates the air. In Summertime the roof is opened. Air drawn in through the base of the courtyard, or through windows opening onto street and courtyard, provides both stack and crossventilation. Three wind generators (installed capacity 4.5kW) and photovoltaic panels on the roof, together with

cheap night-rate electricity, charge a battery pack which is used for lighting and for emergency standby power. Rainwater collected on the roof supplies two thirds of water requirements for bathrooms, wcs and showers. This water is heated by a Thermomax evacuated tube solar collector on the roof. An electric immersion unit was installed as backup, but has not yet been needed. Projected overall energy savings are 90% over a conventionally designed building; the reduction in CO 2 emissions is expected to be 73%, and in running costs 87%. Windows of softwood from managed plantations have water-based solvent-free paint finishes, and kitchen fittings are made of recycled pitch-pine. Floor coverings include linoleum, natural jute and recycled terracotta tiles. A bicycle park instead of a car park, and the use of recycled copper cylinders and bicycle parts for column cladding and balustrades complete the 'green' agenda. When the apartments were put on the market in September 1994, prospective buyers queued overnight and all eight were sold within thirty minutes. The architects were Murray O'Laoire Associates and the services engineers Homan O'Brien Associates. For information contact: Temple Bar Properties Ltd., Crow Street, Dublin 2.

Office building at Ashdown Business Park.

AN ECOLOGICALLY SOUND BUSINESS PARK The objective at Ashdown Business Park is to build commercially attractive office space which meets or exceeds all current environmental design criteria while costing less to run. Compared with a conventional air-conditioned office building, it is predicted that running costs will be reduced by 38%, energy consumption by 64% and carbon dioxide emissions by 65%. The THERMIE project includes five buildings totalling 5,300m2, on a rural site.

The hollow-core concrete floor and roof planks of the 'TermoDeck' system constitute the principal energy feature of the buildings. In Summer cool air is circulated through the slabs at night. During the day the cooled structure absorbs internal heat gains, and warm outside air is drawn through the slabs to ventilate office spaces. In Winter the opposite applies, with heated air circulating through the slabs at night and the structure storing warmth to keep the indoor temperature at the correct levels during working hours. Because only small amounts of preheated or pre-cooled air are needed to adjust room temperatures, constant fresh air can be supplied without noise or draughts. The use of 100% fresh ventilation air should avoid many of the features of 'sick building syndrome'. Off-peak energy provides most of the heating and cooling, and heat from exhaust air is reclaimed.

cabling is supplied from a perimeter skirting system. In larger buildings cabling can be carried in those slab cores which are not needed for air circulation, and suspended ceilings can be used provided they are of an open-grid type which will not obstruct air-circulation.

Raised floors and suspended ceilings are omitted to maximise heat transfer between 'TermoDeck' slabs and interior spaces. In these small buildings power and data

L • E • O LOW ENERGY OFFICE IN COLOGNE The clients wanted a building which would save energy, respect the environment and meet all modern comfort standards, with a payback period of not more than ten years. The primary strategy was to

ensure that the enduring aspects of the building were right. The architects advised on the selection of the site, and proposed a compact daylit threestorey over basement atrium-type building with North and South orientation of the main facades and no windows to East or West. The 2700m 2 L • E • O building, like Ashdown Business Park, is very well insulated, has high thermal mass and circulates air through hollow-core concrete slabs. There are no raised floors or suspended ceilings. Sunlight and daylight are redirected to avoid glare and provide high quality illumination during daylight hours. Transparent insulating material, with external sun screens, is used on the South facade. In Winter fresh air is warmed by being drawn through a 150m earth duct which encircles the building, then heated by a 49kW gas-fired condensing boiler to provide all space heating. Outgoing air is circulated through the atrium and its heat recovered. Construction costs for this system were one third those of conventional air-conditioning. Summer cooling is provided by night purging through the atrium between midnight and morning. During the day incoming cool air from the earth duct ventilates seminar rooms. Heating and ventilation levels in the office spaces are controlled by the occupants and all windows are

openable. Hot water is supplied by local heaters. Artificial lighting is controlled automatically in response to daylight levels. Construction began in December 1993 and was completed recently. Dynamic simulation was used to analyse and modify the building during the early design stage and a two-year postconstruction evaluation process will assess whether the calculated savings of 75% for heating, cooling and electricity are achieved. The architects emphasise the need, in a building of this kind, for a post-occupation phase of education for the building users. The architects are Dipl.-Ing.

TWO TRAINING SCHOOLS IN ONE A unified architectural solution brings together the School of Building and Public Works (CFBTP) and the School of the Chamber of Trades (CFI), which trains apprentices for jobs as mechanics, bakers, butchers and fishmongers, hairdressers and salespersons. They share residential and canteen facilities while maintaining their separate organisational identities. The 20,000m2 complex at La Rochesur-Yon is designed to optimise the use of daylight while maintaining thermal comfort. The lighting is managed by a BEMS system. Predicted energy savings are 99 TOE/year of which 550,000 kWh/year (47 TOE) should be attributable to savings on lighting. It is expected that reduction of pollutant emissions will be significant. The architects were Durand-MénardThibault, La Roche-sur-Yon, and Fabrice Janneau, Paris. For information contact: D. Destouches, Hôtel de la Région, 1, rue de la Loire, F - 44066 Nantes, cedex 02.
