Development of a novel low pressure technique for measuring the air tightness of buildings

由环境过程系统(EPS)、诺丁汉大学(UON)、技术研究(ANDtr)、绝对空气与天然气(AAG)、Elmhurst Energy Systems(EES)和国家能源基金会(NEF)组成的一个联盟正在开发一种更高效、更准确、更适合评估人员和居住者友好的方法来确定现有住宅的气密性。这将有助于提高基线业绩评估的准确性以及升级建议的适用性和影响建模。新仪器还将使气密性性能和合规性检查变得更容易，并将从根本上将现有的气密性测试市场从小规模的专家服务提供转变为评估员、建议提供商、改装安装人员、承包商和建筑控制人员都可以自己进行泄漏评估-允许在整个改装过程中进行定期筛查，并促进开发更有效的方法来改善和管理气密性和通风。

A consortium comprising of Environmental Process Systems (EPS), the University of Nottingham (UoN), AND Technology Research (ANDtr), Absolute Air & Gas (AAG), Elmhurst Energy Systems (EES) and the National Energy Foundation (NEF) are developing a more efficient, accurate and assessor and occupant friendly means of determining the air tightness properties of existing dwellings. This will help improve the accuracy of baseline performance assessments as well as the applicability and impact modelling of upgrade recommendations. The new instrumentation will also make airtightness performance and compliance checks more accessible and will fundamentally shift the existing air tightness testing market from a small scale specialist service offering to one where assessors, advice providers, retrofit installers, contractors and building control can all undertake leakage assessments themselves – permitting regular screening throughout the retrofit process and accellarating the development of more effective methods for improving and managing airtightness and ventilation.
