BLP LCC for sustainability: online toolkit modelling capital costs,operational costs,embodied and running energy costs and CO2 emissions for dwellings

提供一个工具包，以满足当前和未来对生命周期成本、能源成本和二氧化碳排放优化的需求。这些要求的驱动因素存在于公共采购指导中，如HCA资金、具有法律约束力的碳预算（2009年）、低碳产业战略、建筑业低碳审查的预期结果、实现卓越指南，以及更广泛的建筑法规修改建议和莱瑟姆报告。BLP的调查和对专业人士的采访证实，需要快速准确地评估替代设计，以实现可持续发展目标，如可持续住宅规范（将在应用程序中建模）。该工具包不仅可以在资本和运营成本的背景下评估最佳性价比，还可以确定在建筑物的生命周期内最佳地减少碳排放。为了实现到2050年二氧化碳排放量减少80%的目标（2008年气候变化法案）和欧盟到2020年减少20%的目标，需要对现有建筑进行重大的能源改进。现有建筑的能源效率和改造措施需要在整个生命周期内得到有效解决。

To provide a toolkit to meet current and future needs for optimisation of life cycle costs, energy costs and CO2 emissions. Drivers for these requirements reside in public procurement guidance such as HCA funding, the legally binding carbon budget (2009), the Low Carbon Industrial Strategy, anticipated outcomes form the Low Carbon Review of the Construction Industry, Achieving Excellence Guides as well as more broadly in the proposed changes to Building Regulations and the Latham report. BLP surveys and interviews with professionals confirm the need to assess alternative designs quickly and accurately to achieve sustainability targets such as Code for Sustainable Homes (which will be modelled in the application). The toolkit enables best value for money not only to be assessed in context of capital and operating costs but determination of best reduction in carbon for money over the life of the building.Significant energy improvements are required to the existing building stock to meet the 80% reduction in CO2 emissions target by 2050 (Climate Change Act 2008) and the European Unionj target of 20% reduction by 2020. The energy efficiency of existing building and retrofit measures will need to be addressed effectively over the life cycle.
