New research shows that replacing low efficiency window air conditioners with high-efficiency units can produce measurable savings and can be cost-effective in homes with high air conditioning electricity consumption.
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.
The ventilation requirements for decontamination are normally determined with a static calculation method. In some cases, the pollutant emission is intermittent, for example in the car park of an office building, where all the cars enter and leave the place nearly at the same time. Generally, in such a case, the volume of the garage is large, consequently the time constant of the system has a high value. So a static approach would no longer stay accurate and a dynamic evaluation is needed.
Ventilation air distribution problems involving system design, installation, operation and maintenance are often suspected of causing air quality problems that plague many modern sealed office buildings, such air quality problems have resulted in occupants suffering symptoms of discomfort and ill health. Three case studies are described in which tests of ventilation performance appear to relate poor air quality to air distribution and ventilation. In all cases, ventilation system retrofits were designed to improve indoor environmental conditions.
After numerous tests and experiments on the best way to overcome the problems associated with Bus Garage Ventilation, a simple solution was arrived at - being the most effective and economic.
