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

英国致力于到2050年将温室气体（GHG）排放量减少80%，并根据5年碳预算确定了实现这一目标的进程。尽管国内建筑占英国温室气体排放量的27%，但目前的房屋翻新方法无法提供实现这些目标所需的减排速度和深度。因此，大不列颠翻新计划的成本约为400亿英镑。这是英国历史上建筑业面临的最大挑战，如果英国要在应对气候变化方面发挥作用，这一挑战至关重要。从业人员将需要适当的工具来帮助实现政府的目标。拟议的工作将产生一个这样的新工具，以帮助以最低的成本实现这些目标。TSB提案中概述了影响的主要途径，即通过开发软件供建筑客户、专业顾问和建筑商使用，以便在建造新住宅或翻新现有住宅时，在生命周期成本、能源成本和二氧化碳排放方面优化住房建设解决方案。该工具包提供了一种手段，根据生命周期成本、能源和可持续性指标来评估符合可持续性基准的建筑，以证明物有所值。该工具包促进了施工过程（制造、设计、施工、维护和改造）所有阶段的成本和能源优化，最终造福于最终用户，更广泛地造福于社会。这项研究将直接使英国政府、地方当局、住房协会、建筑业以及最重要的住户及其家庭受益。除了直接将研究成果转化为用于真实的项目的软件外，研究成果很可能还有助于制定政府政策。特别是，伦敦大学学院目前与社区和地方政府部签订了一项框架协议，以开展研究，支持建筑法规L部分的制定。包含和运行成本能源将使快速敏感性测试能够进行，以帮助确定未来建筑法规（2013年和2016年）的适当能源效率水平。

The UK is committed to an 80% reduction in greenhouse gas (GHG) emissions by 2050 and has defined a process based on 5-yearly carbon budgets to meet this aim. Despite domestic buildings being responsible for 27% of the UK's GHG emissions, current approaches to refurbishing homes are unable to deliver the speed and depth of emission reductions needed to meet these targets. The Great British Refurb has therefore been proposed at a cost of around 400BN. This represents the largest construction industry challenge in British history and is vital if the UK is to play its part in tackling climate change. Practitioners will need appropriate tools to help meet the government targets. The proposed work will generate one such new tool to help achieve these targets at least cost. The main route to impact is outlined in the TSB proposal i.e. via the development of software for use by construction clients, professional advisors and constructors looking to optimise housing construction solutions in respect of life cycle costs, energy costs and CO2 emissions when building new or refurbishing existing dwellings. The toolkit provides a means to evaluate construction which meet sustainability benchmarks based on life cycle costs, energy and sustainability metrics to demonstrate value for money. The toolkit promotes optimisation of cost and energy at all stages of the construction process (manufacturing, design, construction, maintenance and retrofit) for the ultimate benefit of the end user and more broadly for society. The research will directly benefit the UK government, local authorities, Housing Associations the construction industry and above all householders and their families. In addition to the direct implementation of the research into software for use on real projects it is very likely that the results of the research will also be useful to help develop government policy. In particular, UCL currently has a framework agreement with the Department of Communities and Local Government to undertake research to support the development of Part L of the Building Regulations. The incorporation of embodied and running cost energy will enable rapid sensitivity tests to be undertaken to help determine the appropriate levels of energy efficiencey for future Building Regulations (2013 and 2016).
