Energy efficient retrofitting of a 1950-ies multi-dwelling block house considering hygrothermal properties – field measurements and simulation
(2012) 5th International Building Physics Conference p.201-208- Abstract
- Elevated moisture contents due to exposed weather conditions and ageing façade materials can often lead to degradation and increased risks for the building walls, but also affect the insulating properties of the materials, as thermal and hygric behaviour of building materials are closely interconnected. This paper presents the first results from a study of a 1950-ies multi-family building with a previous history of high moisture levels in it walls and subsequent indoor related moisture problems. The study includes an on-site field measurement programme with continuous monitoring of hygrothermal conditions throughout selected walls, as well as indoor conditions of tenants apartments, pre- and post-retrofit. The results from the conducted... (More)
- Elevated moisture contents due to exposed weather conditions and ageing façade materials can often lead to degradation and increased risks for the building walls, but also affect the insulating properties of the materials, as thermal and hygric behaviour of building materials are closely interconnected. This paper presents the first results from a study of a 1950-ies multi-family building with a previous history of high moisture levels in it walls and subsequent indoor related moisture problems. The study includes an on-site field measurement programme with continuous monitoring of hygrothermal conditions throughout selected walls, as well as indoor conditions of tenants apartments, pre- and post-retrofit. The results from the conducted field study are compared to calculated transient hygrothermal simulations and the thermal properties of the building component, and their impact on heat losses are evaluated. The results show that the chosen ETIC-system had a favourable effect on the moisture content of the walls and facilitates a quick drying of the accumulated moisture in accordance with the simulated results. It is also shown that the thermal performance increases as the walls dry out in addition to the increase by the extra insulation, and the hygrothermal properties of the retrofitted walls depending on choice of ETIC-system are also investigated.
