Technical Brochure

8: Solar Domestic Hot Water System in a Large-Scale  Housing Development in the Netherlands

 About 1,000 houses in a single project are being provided with a solar domestic hot water system.  Energy-saving considerations were an important factor in the design  of the houses. The large scale reduced the hot water system cost by about 20%, which results in a pay-back period of about 35 years. The construction started in May 1993 and is due for completion in mid-1995. (Printed 1994)

21: Solar Energy Heats Indoor Swimming Pools in Norway

 A new solar energy system, the Solar Energy Roof, is integrated into the roof of the  Gullbring Centre in Telemark, Norway. Two swimming pools are supplied with heat recovered  from dehumidified ventilation air and other sources and with heat from two solar energy systems, one for each pool. The  system has been in operation since April 1994. (Printed 1995)

23: Central Solar Heating Plant with Short-term Storage in Sweden

This central solar heating plant is connected to the district heating system of  Falkenberg, a small town in Sweden. The plant includes a ground-based flat-plate solar collector array  of 5,500 m and an insulated steel storage tank holding 1,100 m of water. Between 1990-92 the annual average  of the solar heat delivered to the district heating network was 1.53 GWh (280 kWh/m), which makes up 6% of the total  heat delivered. (Printed 1995)

56: Solar Panels Supplement District Heating in Denmark

 In Marstal, Denmark the oil-fired  district heating system is supplemented by heat from a large solar collector system. The typical annual heat output of the  Marstal system is about 26,000 MWh. Annual output of the solar collectors is about 3,250 MWh, replacing  about 350,000 kg of waste oil. The solar system consists of 640 collectors with a combined area of 8,064 square metres. By using solar energy to supplement the district heating system, emissions of atmospheric pollutants have  been reduced. (Printed 1997)

64: Low-energy Apartments in the Netherlands

The Urban Villa project concerns 16 low-energy apartments in an apartment block in Amstelveen, the Netherlands. The project demonstrates the technical feasibility of minimising the  energy consumption of a home without sacrificing the living comfort. Domestic energy costs have been reduced by 45 percent compared to conventional apartments of comparable size. (Printed 1998)

73:Low-cost Solar Air Collectors Dry Flower Bulbs, (The Netherlands)

 A flower bulb company uses a 200 m2 solar air collector to provide heat for bulb-drying. During the 1996/97 drying season the installation provided about 152 GJ, equivalent to 5,445 m3 of natural gas, or 38% of the energy requirement for drying.

78: Integration of Solar Collectors into the Building Process, (Sweden)

A new type of prefabricated solar collector roof module has been used successfully in a residential building development.  This new design has considerably simplified  the integration of solar collectors into the building process. The solar system cost only 2% of the total  building costs

85: Novel Heat Pump System Exploits Ambient Energy

This novel heat pump system uses ambient energy, such as natural  convection, wind and solar radiation.  It consists of outdoor panels, which effectively absorb and  dissipate heat; storage units, which make ice by direct expansion refrigeration; and a compressor.  The system is  installed on a commercial building in Tokyo, where it is performing well.

100: 'Zero-energy' House with Solar  Panels Built at the Coldest Place in Japan

A demonstration 'zero-energy' house has been built at Asahikawa, Hokkaido, the coldest place in Japan.  The  special design of the house has reduced energy consumption to one fifth of that of an ordinary house, while providing increased comfort.  Roofed with 12.5 kWp PV panels and equipped with a 5 square metre solar thermal  collector, it can produce enough  energy to meet its annual consumption.

105: Solar Thermal Demonstration System with a Large Paraboloidal Dish Concentrator

A large paraboloidal dish solar concentrator, featuring a hexagonal aperture unit covered  with 400 m2 of mirrors, has been developed in Australia.  By tracking the sun throughout the day, the dish produces superheated steam in a boiler placed at the focal point of the concentrator.  The steam is expanded in a 50 kWe steam engine/generator set.  The demonstration dish has produced 60 MWh of solar power over four years. (Printed 1999)

120: Solar-heated Dwellings with Seasonal Storage

In 1984, 96 houses in a Dutch village were equipped with solar collectors, a large underground heat store and a low-temperature central heating unit. The houses were monitored from 1984 to 1996, providing an opportunity to assess the long-term performance of such systems. Over the 12 years, the solar heating system functioned well and supplied about 54 percent of the total heat demand of the houses. (Printed 2000)

131: Air-conditioning System Exploiting Natural Energy

An Environmental Technology Centre in Shiga, Japan has been designed to use natural energy to reduce its primary energy demand by 20 percent. Passive solar design features, active solar heating technology and the use of natural daylight and ventilation have been combined with a number of energy saving features. The Centre is a showcase for sustainable building techniques. (Printed 2000)

Review of Large-scale Solar Purchasing (1998)

A Review topic studying issues influencing large-scale purchases (procurement) of Active (thermal) Solar Energy systems. This work  was undertaken jointly by the IEA Solar Heating and Cooling Programme and CADDET Renewable Energy; it aims to encourage utilities and housing companies to buy active solar systems on a large scale, thereby reducing prices. A full report of this  work was published in December 1998. The full report cab be obtained from National Teams (for member countries) or from the CADDET Centre (for non members, price GBP 15). It can also be downloaded for free as a pdf file (note this file is 745 kbytes). A summary of this report is also available as a pdf file (340 kbytes). To read pdf files you will need Adobe Acrobat Reader.

Active Solar Energy Mini-Review (1995)

Held in Copenhagen during 1995 and led by Mr Ken Sheinkopf from the Solar Energy Education and Research Foundation (USA). Close links were maintained with the IEA Solar Heating and Cooling Programme. The review covered active solar energy for: (1) domestic hot water systems, (2) commercial buildings and industrial systems, (3) swimming pool systems, and (4) district heating systems. High temperature solar heating technologies were not included. The final report on the study is available from the CADDET Centre or National Teams.
