Validation of Dynamic Thermal Simulation Programs with Data from Full-Scale Buildings

在建筑节能和环境性能评估中，动态热模拟程序的验证研究已经有了很长的历史。由于需要开发更节能的设计，这些程序正变得越来越广泛地使用。然而，没有适用于经验验证的有用的全尺寸建筑数据集-大多数研究都集中在测试室的比较验证或经验验证。需要这样的数据集，特别是对于低能耗建筑物，以说服监管机构和商业建模公司的客户，这些程序适合目的，并且可以可靠地预测建筑物的能源性能。拟议项目将对采用嵌入式低能耗技术的全尺寸建筑物进行实证验证研究。该研究将补充新批准的IEA（国际能源署）ECBCS附件58项目的目标，该项目题为“基于全尺寸动态测量的可靠建筑能源性能表征”，旨在开发可靠的现场测试方法和分析技术，以表征建筑物的实际能源性能。IEA附件58的一个重要内容是从全尺寸建筑物中获取和分析详细的动态性能数据。由于成功的经验验证的严格要求，这些建筑物的一个子集将被选择用于开发高质量的经验验证数据集，并将遵循一系列越来越复杂的实验。特别是，有一座建筑物已被确定为适合进行必要的实验-丹麦的能源灵活之家;其他建筑物将作为国际能源机构工作方案的一部分，但重点是少数高质量的数据集，而不是更多的具体数据集。IEA项目将持续3年，目前的建议是进行符合IEA附件总体目标和时间表的研究，允许英国参与验证工作。

There has been a substantial history of validation studies for dynamic thermal simulation programs used in building energy and environmental performance assessment. These programs are becoming more widely used as a result of the need to develop more energy efficient designs. However, there are no useful full-scale building datasets suitable for empirical validation - the majority of studies have focused on comparative validation or empirical validation in test rooms. There is a need for such datasets, particularly for low energy buildings, to convince regulatory authorities and clients of commercial modelling companies that the programs are fit for purpose and can reliably predict building energy performance. The proposed project will undertake empirical validation studies on full scale buildings with embedded low energy technologies. The research will complement the objectives of the newly approved IEA (International Energy Agency) ECBCS Annex 58 project entitled "Reliable building energy performance characterisation based on full scale dynamic measurements" which has the intention of developing reliable in situ testing methods and analysis techniques for characterising the actual energy performance of buildings. An important element of IEA Annex 58 will be obtaining and analysing detailed dynamic performance data from full-scale buildings. Due to the rigorous requirements for successful empirical validation, a subset of these buildings will be selected for developing high quality empirical validation datasets and a series of experiments of increasing complexity will be followed. One building in particular has been identified as suitable for conducting the necessary experiments - the Energy Flex House in Denmark; others will follow as part of the IEA work programme, although the focus is on a few high quality datasets rather than a larger number which are less well specified. The IEA project will run over a 3 year period and the current proposal is to undertake research fitting into the overall objectives and timescales of the IEA Annex, allowing UK participation in the validation work.
