Approximately 35% of US single-family houses contain forced-air heating and cooling ducts that pass through unconditioned spaces. These duct systems have been shown to have a potentially large. Influence on energy use and ventilation rates. To investigate the parameters affecting the performance of these systems, a 31-house field study of distribution-system performance based on diagnostic measurements was performed in California, and an integrated airflow and thermal simulation tool was developed.
Computer-based control systems have been widely used for controlling air-conditioning systems in commercial buildings. Computer-based control technology can increase control accuracy and can implement various sophisticated control strategies so that building energy consumption can be reduced. The problem is not how to implement a control strategy, but which control strategy should be used to control air-conditioning systems in commercial buildings.
One of the most important projects of the 1990s has just been completed - the naturally ventilated School of Engineering at De Montfort University in Leicester. Roderic Bunn reveals how it could influence a new breed of environmentally sensitive buildings.
Gives a personal assessment of the most important energy utilisation techniques. Describes low-energy buildings, the building fabric, ventilation, energy saving heating systems, including oil heating, gas heating, wood-firing systems, heat pumps, co-generation, solar systems (active), heat emission and heat control; and waterheating.
Sunlight from above can enliven a house dramatically. Designers, builders and homeowners who understand the energy aspects of skylights can best select them for comfort as well as appearance.
