英国的学校是现有建筑存量的一部分，政府必须减少运营碳排放，才能实现到 2050 年将碳排放量比 1990 年水平减少 80% 的目标。国家资助翻修是公立学校最可行的选择，有两种途径： 条件改善基金 (CIF)，仅限于改善学校设施的实体方面（例如扩建）； Salix 能源效率基金 (SEEF) 旨在采取能源/设备改造措施。尽管 BIM 技术（以政府软着陆 (GSL) 框架为基础）的使用以及能源建模和模拟工具的使用已成为提高建筑物能源效率不可或缺的一部分，但它们因缺乏采用而受到限制。本研究采用混合方法来研究当代 BIM 和能源模拟技术在现有校舍翻新中的有效性。从受益于 SEEF 的学校的 10 个案例研究中收集的二次定量数据得到了对 7 名接受过 SEEF 整修的学校校长的采访的支持。结果表明： CIF 和 SEEF 在管理上是相互排斥的资金流，由于建筑物的物理围护结构与设备和系统使用的热传递和能源的相互作用，应该协同运作；一些学校没有获得关于如何优化从 SEEF 获得的资金的技术建议，从而导致非最佳投资。提供的建议包括：向学校校长提供有关 BIM 和 GSL 的广泛培训，并建议政府机构协调 CIF 和 SEEF 的目的，以提供学校碳减排的整体解决方案。
Schools in the UK are part of the existing stock of buildings whose operational carbon must be reduced for the government to meet its objective of reducing carbon emissions by up to 80% of their 1990 levels by 2050. State funding for refurbishment is the most feasible option for public schools using two routes: Condition Improvement Fund (CIF) which is restricted to improving the physical aspects (e.g. expansion) of school facilities; and the Salix Energy Efficiency Fund (SEEF) aimed at energy/equipment retrofit measures. Although the use of BIM technology (underpinned by the government softlanding (GSL) framework) as well as the use of energy modelling and simulation tools have become integral to making buildings more energy efficient, they are constrained by lack of adoption. This study used a mixed-method approach to investigate the effectiveness of contemporary BIM and energy simulation technologies in refurbishment of existing school buildings. Secondary quantitative data collected from 10 case studies of schools that benefitted from SEEF was supported by interviews of seven heads of schools that had undergone SEEF refurbishment. Results showed that: CIF and SEEF which administratively are mutually exclusive funding streams ought to operate in synergy due to the interaction of a building’s physical envelope with heat transfer and energy used by equipment and systems; some schools are not getting technical advice on how to optimise the funds they receive from SEEF leading to non-optimal investment. Recommendations provided include: extensive training on BIM and GSL to heads of schools and advise to government agencies to reconcile the purpose of CIF and SEEF for a holistic solution to carbon reduction in schools.
