How does indoor environment change when energy efficiency of a building is improved?


Indoor environmental quality is influenced by ventilation, thermal conditions, noise, lighting, and indoor air pollutants such as particles, microbes, chemical impurities, and radon.

INSULAtE-project aims to demonstrate how energy improvements impact on these indoor environmental parameters, and to develop a protocol for assessment of the impacts. In the first Phase, case study measurements will be performed in Finland and Lithuania, including 20 multi-family buildings per country (200 apartments). In the second Phase, the goal is to extend the assessment in a total of 50 multi-family buildings in Finland.

 

Situation in May 2014

Field studies started in Finland and Lithuania in the fall of 2011. By the end of the heating season of 2012 - 2013, the pre-renovation measurements have been conducted in 16 buildings (101 apartments) in Finland and in 20 buildings (96 apartments) in Lithuania. Out of these 36 buildings, post-intervention studies have been conducted in fifteen buildings so far. The schedule of post-intervention measurements in rest of the buildings is depended of renovation schedules of each building.

As a part of Phase 2 activities, baseline assessment has been conducted in 26 buildings, and post-renovation studies have been conducted in five buildings. These studies have been focused on collecting long term follow-up data on thermal conditions, CO2 / ventilation, and occupant health and well-being. Also selected environmental monitoring and sampling will be conducted in Phase 2 buildings.
