Performance of a solar air collector at a CEC demonstration project, Easthall, Glasgow.

The paper describes the design strategy and performance of an air-driven solar water and ventilation preheat system, an integral part of a CEC Demonstration Project in Glasgow; noting how performance has been compromised partly by inherent, and partly unforseen design aspects - e.g. unexpected intervention by the user. There are 12 collectors and measurements described in this paper are restricted to one which faces South-East with a tilt of 30°.

Investigation of a novel method of using wall cavities to preheat ventilation air using both solar energy and heat recovery.

This paper describes the analysis and practical testing of a novel method of pre-heating ventilation air for buildings by sucking the air from the cavity space in an external wall. The fresh air introduced into the building is pre-heated partly by recovery of the heat escaping through the inner leaf of the wall and partly by collection of some of the solar energy incident on the outer leaf of the wall. A classroom at Napier University in which the system was installed was monitored to assess the energy and comfort benefits.

A building integrated solar collector designed to preheat fresh air during the heating season.

A building integrated solar collector was designed to preheat the fresh air used to ventilate a commercial building in Norway. The solar collector is a 50 meters long air chamber that runs along the ridge of the sloped roof. There is a fresh air intake at each end of the collector. An air intake to the ventilation system at the center of the collector causes fresh air to flow through the collector. The energy consumed for lighting, heating, ventilation, hot water, and plug loads has been monitored since Spring 1993.

Mesoscale meteorological and air quality impacts of increased urban albedo and vegetation.

The large scale implementation of high-albedo building materials and urban surfaces and the reforestation of low vegetation urban areas are being encouraged as energy-saving measures. These strategies will result in modification of the physical properties of millions of buildings (e.g roof reflectance) and th ei r microclimates (e.g., shading, wind, and evapotranspiration effects of trees). This paper is about the atmospheric impacts of regional scale changes in building properties, paved-surface characteristics, and their microclimates.

Remodelling with the sun.

Remodeling is the perfect time to improve daylighting, direct gain heating, and shading with passive solar techniques. It can also provide the best opportunity to add solar water heating or even photovoltaics to a home.

Passive solar system for a school in a snowy region.

The new buildings of Kaneyama Town Junior High School demonstrate that a well-planned and adequately designed passive solar system can work effectively even in a snowy and cold area. The OM solar system of an air heating type applied here, which is characterised by heat collection through roofs, and underfloor heating and heat storage, provides the pupils with a comfortable thermal environment in winter.
