The objective of this paper is to present long time monitoring and post occupancy evaluation of theMoravian Metropolitan Library with the ventilated solar faade used for space heating and with mixing chamber for cooling with the forced ventilation. In consequences of new requirements from the EU Energy Performance of Building Directives 2002/91/EC and changing Czech building regulations is necessary support collective research effort on quality assurance and standardization on solar components and installations in buildings.
As a large part of the education year occurs during the cold weather season, the proportionally largeglass areas permit excessive heat loss in the classrooms. The problem with large glass areas arisesfrom the lack of control of mechanically generated heating systems. A solution for the improvement of these classrooms, is to use solar energy in the design, which is economical and practical. In thisstudy, a school in Istanbul, which has existing large classroom windows and has a solar energycollector behind the south classroom window is introduced and measurements are evaluated.
In December 2000, a new demonstration building for lighting research "Valotalo" (Light House) wasinaugurated at Helsinki University of Technology. The newest experimental technologies for integration of artificial and daylight were applied in order to validate their efficiency and peoples acceptance. Photovoltaic panels of 7 kW maximum power were integrated in the south faade. A 30 m2 solar heating system mounted on the roof of "Light House" produces warm service water. A daylighting test room is also built on the roof for further daylight research.
The paper deals with on-site measurements of energy benefits resulting from exploitation of double-skin solar energy façade for pre-heating of ventilating air. The southwards oriented façade with total area of 1135 m2 on a new building of Moravian Library
Within the program "Solar Optimized Buildings" which is funded by the German Ministry of Economy (BMWi), a building for the DB Netz AG has been realized and monitored. The design concept of the building is dominated by architectural solutions for ventilation, cooling and lighting of the office rooms. Due to the change of responsibilities during the design and building process, the targeted primary energy consumption of 100 kWh/m 2 y has been exceeded so far. The reasons lie primarily in the inadequate operation of the technical systems for heating, ventilation and artificial lighting.
Detailed simulation studies on the design and development of PV/T systems are being carried out at the Politecnico di Milano, for their possible integration with a sloped roof. Subsequently, a proto-type PV/T air heating collector has designed, manufactured and tested at the experimental site Parco Lambro in Milan in collaboration with a private industry. Thermal and electric efficiencies have been assessed during several days of experimentation.
The transformation of the Conservatorio San Giuseppe , into the Cospicua Residential Home for the Elderly has become a landmark in the neighbourhood. It brings past and present together with its old church and stepped new development incorporating a colourful orange windbreak. It is an example of how an old building, originally an orphanage for girls, with limitations of location and orientation could be rehabilitated to incorporate energy efficient features. Both the original structure and the new construction are load bearing with a high thermal mass to utilise a direct gain system.
Winner of First Prize in the 2 nd Commonwealth Inter-school Design Competition organised by theCommonwealth Association of Architects (CAA), 1991. The winning design was a pair of houses with wind towers. It was praised by the jury as an innovative and original solution to the brief recognising local conditions, elegantly and thoughtfully presented. The planning of the dwelling pleasantly reflected the local lifestyle with an interesting internal environment.
A new type of residence (the SEA house) has been proposed in winter, the house is heated by solar energy. Thermal insulation, heat storage, and air circulation are used to maintain the room temperature at a comfortable level and to reduce the temperature difference between the south side and the north side of the house. In summer, earth tubes are used for the purpose of cooling the proposed house. The thermal performance of the house was simulated by a computer program called PSSP, which can predict room temperature in a multiroom system.
