Life Cycle Assessment (LCA) in many ways is a methodology which building industry is looking towardsto give the answers on how to assess sustainability of buildings. In Hong Kong, like many othercountries, its application is limited by the availability of credible assessment tools in the market. Thispaper provides the details on the processes and findings of a comprehensive study initiated by theGovernment to derive a LCA tool for the use of the local building industry, addressing on researches thatare needed to really make LCA part of the answer to sustainability assessment.
1. Thoughts 1. Why care? 2. Sustainable Architecture or just Architecture, are they something different? 3. On past and future – learning from tradition. 4. On the overwhelming power of design. 5. On starchitecture. 6. On the design process and the golden
SERRAGLAZE is a breakthrough daylighting system designed to be incorporated into the primary glazing of normal sidelit rooms to save energy and enhance comfort.The paper describes the design, construction and optical properties of the plastic SERRAGLAZE panel, the key component of the system.
The paper deals with a complete procedure for the calculation of material embodied energy inthe building sector using a Life Cycle Assessment (LCA) approach; the calculation of embodied energy for building material and components during the design phase takes into account both material durability and frequency of maintenance interventions. As a case study an evaluation of embodied energy for three different types of external walls is reported: external insulation coated, single stratum and multi strata.
The proceedings of this conference cover the following topics: building design process; commissioning, operation and maintenance; controls and measurement; energy and building; heat pump and panel heating and cooling; HVAC systems and equipment; IAQ and ventilation; indoor air pollution; miscellanea; modelling and simulation; museums and historical buildings; noise control and lighting; passive/evaporative cooling and refrigeration; refrigeration and passive cooling, heat pumps, panel heating and cooling; refrigerant substitution issue; and thermal comfort.
The use of superinsulation is normally associated with climates that are colder and less temperate than that of Auckland, New Zealand. However, if life-cycle energy analysis is undertaken, which incorporates operating and embodied energies and the energy of replacement parts over the life of the building, it can be shown that superinsulation of standard New Zealand lightweight construction more than halves the life-cycle energy of a typical house.
