摘要: At the last IEA Annex 32 meeting it was proposed that annex develop links between level 1 (the whole building performance) and 2 envelope system). This paper provides a case study of just type connection. An exterior wall mockup is hot box tested modeled in laboratory. Measurements steady state dynamic behavior this are used as basis to define thermal bridging, mass benefit air tightness system. These two performance characteristics related performance. They can be analyzed by finite difference modeling assembly. equivalent theory convert three dimensional heat flow one terms capture effects, which turn common simulation model. illustrates check Massive ICF (Insulating Concrete Form) system mocked up (level 2) Whole Building Performance criteria 1) such total space heating cooling loads (thermal comfort).
