一、立项背景
随着我国经济和社会快速发展,大型公共建筑日益增多。为满足以人为本的设计思想,并贯彻住建部新时期大型公共建筑建设“确保建筑全寿命使用周期内的可靠与安全.注重投资效益、资源节约和保护环境”的新要求,大型公共建筑已不仅仅局限于采用单一传统的结构形式.而是综合不同结构形式的优点,以实现公共建筑建设的综合效益最优。 相似文献

Buildings are long-lasting products which have huge impacts on the environment during their whole lives. The design of buildings should take into consideration long-term environmental and economic benefits. A life cycle assessment approach is developed and demonstrated in a case study—the strategic design of a Flagship Store in Shanghai. Industrial practitioners were invited to the feasibility study. Their opinions were included in the life cycle assessment for the first time. The economic analysis takes account of not only the capital costs of the design options but also the running costs during the building's economic life cycle. The methodology adopted is an integrated life cycle assessment process including life cycle costing, multi-criteria decision making and group decision making methods. The workshops are successful in terms of educational opportunity for the practitioners and have obtained good feedbacks. The top 10 sustainable design options after the life cycle assessment process were chosen by the practitioners as the compulsory design strategies in their global environmental development agenda, whilst the other 32 design options as optional design solution for the international retailer's future stores. The life cycle assessment tool demonstrated by a case study was proven to be a simple and efficient design tool in practice, and therefore it can be adopted in other projects to assist the decision makers. 相似文献

The design and assessment of net-zero buildings commonly focus exclusively on the operational phase, ignoring the embodied environmental impacts over the building life cycle. An analysis is presented on the consequences of integrating embodied impacts into the assessment of the environmental advantageousness of net-zero concepts. Fundamental issues needing consideration in the design process – based on the evaluation of primary energy use and related greenhouse gas emissions – are examined by comparing three net-zero building design and assessment cases: (1) no embodied impacts included, net balance limited to the operation stage only; (2) embodied impacts included but evaluated separately from the operation stage; and (3) embodied impacts included with the operation stage in a life cycle approach. A review of recent developments in research, standardization activities and design practice and the presentation of a case study of a residential building in Norway highlight the critical importance of performance indicator definitions and system boundaries. A practical checklist is presented to guide the process of incorporating embodied impacts across the building life cycle phases in net-zero design. Its implications are considered on overall environmental impact assessment of buildings. Research and development challenges, as well as recommendations for designers and other stakeholders, are identified. 相似文献

目前盾构隧道设计方案决策,仅考虑初期投入和建设成本,很少考虑到全寿命成本和社会成本和环境成本,因而有较大的缺陷和局限性。这直接导致了盾构隧道维护成本、建设期交通堵塞成本及环境成本过高,社会负面影响大的问题。基于全寿命周期的盾构隧道经济成本评估正是针对这一问题,从工程学和经济学的角度综合考虑了设计、建设、营运、检测、养护、社会、环境等各个方面的因素,最终以隧道全寿命周期的综合经济成本为指标,以此来评价工程的优劣与经济性。 相似文献
