Pocket sized summary of key energy data. Contains timely, clearly presented data on the supply, transformation and consumption of all major energy sources.
Pressure testing techniques have long been used in the laboratory on building components such as windows, for example, to ensure that rain will not penetrate them under windy conditions.
A literature search was undertaken to assemble and interpretthe-best available· data that can be used for perfonning multizone airflow modelling in mid and high rise apartment buildings. The best currently available data is presented and areas where further field testing research is required are identified. A multizone airflow modelling software tool was used to provide an analysis of ventilation related energy issues in a newly constructed 10 story high-rise apartment building.
Painting large objects like cars or trucks usually generates high levels of pollution that can be eliminated by operating in a closed painting booth equipped with a blowing ceiling which produces a vertical ventilation flow. When the process does not allow the work to be carried out in a completely confined space (in the presence of a travelling crane for example) one of the only ways to remove pollution is the ventilated area. A basic ventilated area is merely a floor area of an industrial premises located above a pit equipped with an air exhaust system.
Night-time cooling of buildings is a recognized way of reducing the use of air conditioning, and hence energy consumption. The paper describes the construction and testing of a latent heat storage system, which uses a novel combination of night cooling, heat pipes and phase change materials (PCMs) and has the distinct advantage that it is suitable for fitting to existing buildings. The design of the heal pipe/PCM heat storage unit is briefly discussed.
