Technical Seminar on International Approaches for Indoor Environment and Energy Use Reduction
Indoor environment conditions have a significant impact on the quality of life given that on average people in Hong Kong spend around 85% of their time indoors. Poor indoor environments in commercial and institutional buildings can impact on productivity and may pose health risks to users. The indoor environment criteria used for the design, such as ISO, CEN, ASHRAE 55, etc., is generally defined by the client and/or consultant appropriate to the type and use of the premises included in the development, and is a basic performance specification. On the other hand, electricity generation accounts for around 60% of the total CO2 emissions from energy use in Hong Kong, and buildings, particularly air-conditioned buildings, account for more than half of the electricity consumed each year. Ensuring buildings are designed for good energy performance is also the key to the conservation of resources and reductions in environmental loadings. Therefore, the design, operation and maintenance of buildings should seek to provide a good quality indoor environment, but with optimum use of energy and other resources.
The first session of this seminar will review the international standards on thermal comfort and indoor air quality on development, national differences, future revision and recommendation. In second session of this seminar, the speaker will present the Energy Performance of Buildings Directive and related standardization with the aims of decreasing energy use in buildings under the Energy Policy in Europe. |
