The Kyoto Commitment: the challenge for UK building services engineers in obtaining a contribution from the domestic sector.

The UK government has signed the Kyoto Protocol and it has committed to reducing C02 emissions to 20% below 1990 levels by 2010. As buildings are responsible for approximately half of the UK C02 emissions, of which the domestic sector accounts for 50%, meeting this target will require a significant contribution from the domestic sector.

Solar heated water is more cost effective than retrofit insulation of facades.

A comprehensive technical and social refurbishment of a housing estate built in the seventies is carried out in the Gardsten project. Well thought out traditional measures are combined with newenergy technology which was initiated through participation in an EU project which, in turn, is based on IEA collaboration.

Home ratings sweep the nation - almost.

As the ratings industry in the United States shifts from a subsidized market to an unsubsidized one, we look at four areas of opportunity for home energy raters. Will these opportunities be growing or collapsing in the 21st century?

New image and lower energy bills in Manchester (USA) inner-city neighbourhood.

The Manchester Project involved the energy efficient rehabilitation and retrofitting of existing housing units plus the construction on vacant lots of new dwellings incorporating energy conservation measures. This project, in the Manchester neighbourhood of Pittsburgh, Pennsylvania, began inthe late 19 70s and was completed in 1983. Energy use and air quality monitoring were carried out for one year after the completion of the project. It was found that in comparison to detached single-family houses using standard construction, energy savings of 75 to 80% were being realized.

Measurements of ventilation performance in a retrofitted conference room.

The ventilation system of a 60 seats conference room was retrofitted to improve indoor air quality. The old, mixing type installation was replaced by a displacement ventilation system. However, the building layout did not allow an optimum location of air inlets and outlets. It was therefore interesting to measure the actual performance of the new system. Using tracer gas techniques, the age of air was mapped within the room, and the ventilation effectiveness was measured in various configurations. The actual air flow rates were also measured in the ventilation system.

DG XII programme, retrofitting of museums for antiquities in the Mediterranean countries.

This project has studied a selection of 16 typical museums for antiquities in five Mediterranean countries and was partly funded by the JOULE III of the European Commission DG XII. Through an elaborate analysis and complete refurbishment of the Archaeological Museum of Delphi, the programme has provided an example for an innovative museum design based on present-day know-how.        

ORME: a multicriteria ranking methodology for buildings.

Rating or ranking techniques are often used for checking compliance with regulations, evaluating the efficiency of a retrofit, or even labelling a building. However, the building is, in most cases, rated on very few parameters - when not only one - among many building qualities that should be taken into account. Within the frame of the Joule-Therrnie OFFICE project, a multicriteria ranking methodology, based on the ELECTRE family algorithms, is being developed.
