ABSTRACT

An improvement in energy performance for existing buildings is needed to fulfil EU energy policy. The efficient way to accomplish the idea of nearly-zero energy buildings (nZEB) is to apply the integrated design process and application of prefabricated insulation elements paired with the expertise of hygrothermal performance. In the current study, the commission of design and construction with emphasis on moisture safety, relying on known quality control programmes, was applied to assure the compliance of nZEB renovation results of an apartment building, where prefabricated timber frame insulation elements were used. The results confirming that the mould index is below critical level M < 1 and moisture content, drying out from the concrete envelope within first 6 months post installation of elements, was 23 kg/m³ and after that, during the next 12 months 12 kg/m³. Analysis showed that it is necessary to force contractors and developers to put into practice quality assurance and moisture safety commissioning processes as a mandatory part of contracting. The results have shown that thorough inspection, strict rules of moisture safety and analysis of designed solutions before, during and after renovation are essential and worthwhile for high-quality, sustainable outcomes of nZEB renovation with timber frame insulation elements.

抽象的

为了满足欧盟的能源政策，需要改善现有建筑物的能源性能。实现零能耗建筑（nZEB）想法的有效方法是应用集成设计流程和预制隔热元件的应用以及湿热性能的专业知识。在当前的研究中，依靠已知的质量控制程序，着重于防潮安全性的设计和建造委员会被用来确保nZEB住宅结构的翻新结果符合要求，在该建筑中使用了预制的木框隔热材料。结果证实模具指数低于临界水平M <1，且在安装元件后的头6个月内从混凝土外壳中干燥的水分含量为23 kg / m ³，此后在接下来的12个月中为12 kg / m ³。分析表明，有必要迫使承包商和开发商实施质量保证和防潮安全调试程序，将其作为合同的强制性部分。结果表明，彻底的检查，严格的防潮安全规则以及在翻新之前，之中和之后对设计的解决方案进行分析对于采用木框隔热材料进行nZEB翻新的高质量，可持续性成果至关重要。
