Focus has been on indoor climate, indoor air quality and energy efficient buildings, for example:

Questionnaire surveys in combination with collecting building characteristics by means of checklists were used to study the indoor environment and energy efficiency in office buildings and residential buildings.

Modelling of indoor air quality and improving building materials especially with respect to odorous emissions. It includes characterisation of emissions from building materials in sensory terms by applying odour panels assessing perceived air quality, studies of the impact on emissions of exposing building materials to ozone, investigations of emissions from building materials containing linseed oil and adsorption and desorption of volatile organic compounds on material surfaces. I have been involved in preparing test protocols for emission testing of building materials.

The impact of ventilation rates on the perceived air quality was studied in offices with different levels of ozone in the air. The effect of mould odour remediation in flats was documented by measurements of perceived air quality and air change rates.

The transient subjective impact on people’s thermal comfort of changing temperature and relative humidity when dressed in hygroscopic or non-hygroscopic clothes was studied.
