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.
The paper outlines the design concept of the condensing boiler and its application in domestic heating systems and discusses the energy savings, investment opportunities and other benefits that can be realised. It also examines the potential market for condensing boilers and some initiatives that are aimed at promoting them in regard to both the end user and the heating designer and installer.
Several case studies from the Iowa State University Extension show that carbon monoxide hazards exist even with new gas appliances. Proper installation and analysis are key to avoiding or solving these problems.
In this paper, theoretic review of a heat pump use and operation is given. Further, the possibilities of a heat pump use in heating and air-conditioning is analysed, especially considering the tourist and catering facilities. The economic and environment protecting effects of a heat pump use as an energy source (conditionally speaking) in the air-conditioning process is pointed out. It is shown that these effect make a heat pump use justifiably attractive.
The belief that the addition of mass to a building will reduce its energy requirement is now widespread. Fiona Cousins and Bob long investigate how this principle, often observed in the coolness of cathedrals, castles and caves during summer, can be applied to modern buildings
