Our areas of interest include: Decarbonising the built environment, including existing buildings.
In order to achieve the global goal of zero Greenhouse Gas (GHG) emissions, the energy use for servicing buildings with heating, cooling, lightning, ventilation etc., must be reduced, and low-exergy solutions must be employed.
We take into account the whole life cycle of the building, including embodied energy and GHG emissions for materials and fittings.
Smart buildings have more optimal design and operation, with the help of digital technology (e.g. multi-parameter optimisation, data-driven methods for building automation, individual demand-control), to maintain human health and productivity whilst reducing GHG emissions.
Built environment is not just isolated buildings, but a holistic look at whole neighbourhoods.
Increased urbanisation poses special challenges related to human health and comfort, such as protecting inhabitants and facades from exposure to poor outdoor air quality, extreme precipitation causing moisture damage and flooding, and the heat-island effect exacerbated by climate change.
But urbanisation also opens up opportunities for community-scale solutions such as renewable energy district heating/cooling and smartgrids with energy storage.

More about the research
The backdrop for our research is UN’s Sustainable Development Goals, most notably
- Sustainable cities and communities
- Affordable and clean energy
- Good health and well-being
- Clean water and sanitation (e.g. Legionella-free water supply)
- Responsible consumption and production (taking into account the whole life-cycle of the building and its materials)
- Climate action
- Industry, innovation and infrastructure
To achieve the above goals requires a highly multidisciplinary. The research group integrates researchers with expertise within:
- Applied engineering — Building physics, building services and controls engineering, renewable energy production, numerical modelling and optimisation (of buildings and their technical services), metrology (we emphasise empirical evidence-based research; our laboratory and field measurement facilities are described below), and meteorology (weather data).
- Health science s— Indoor environment for human health, comfort and productivity, for example indoor microbiology, indoor & outdoor air quality, and sanitation for buildings and health institutions.
We are active in research networks, externally funded research contracts, and integrate research into teaching at bachelor, master and PhD level. We publish high-impact research, and exploit OsloMet's attractive and central location for scientific meetings.
- Climate chamber: 16 m² indoor climate chamber adjacent to a chilled outdoor climate chamber. We have used these to test passive cooling systems (phase change, thermal mass), construction U-value measurements, measuring glazing condensation risk, data-driven controls development, etc.
- Emission exposure chamber with activated carbon filter ventilation/recirculation.
- Microbiology laboratory including incubation equipment, microscopes and fume hoods.
- Building services laboratory fitted with an experimentation/teaching air-handling-unit and hydronic heating system.
- We also share access to the mechanical workshop and makerspace at the faculty.
We have experience with many numerical modelling applications including:
- Building physics: WUFI (pro, bio), Therm, U-calc
- Computational fluid dynamics: Star CCM+
- Generic system numerical modelling tools: EES, Matlab Simulink
- Renewable energy: PV-sys, and models integrated in...
- Advanced building energy modelling: IDA-ICE, EnergyPlus, with GenOpt or MOBO for multi-objective optimisation
- Development and use of low-order models for building energy modelling (e.g. SIMIEN, TEK-sjekk), and whole neighbourhoods (ZENsim)
- BIM applications including Revit, MagiCAD, OneClick LCA
- Machine learning / symbolic regression: Eureqa
- Statistics: SPSS, R
- Airborne pollutants: Particle/aerosol counters (Lasair, P-trak, AeroTrak, DustTrak, LAS-X, also experimental), gas monitors (TVOC, NOx, CO, CO2 , Sarad RTM & Canary radon meters, Lumasense 12-channel photoacoustic multigas/tracer gas monitor), BM Dustdetector for surfaces, Contact plate aspirators (SAS Super, Aquaria Microflow)
- Biometrics/personal exposure: SidePak Personal Aerosol Monitor, Niox Mino Airway Inflammation Monitor, Shimmer GSR sweat & activity loggers, 24-thermocouple suit
- Microbiological: Spore counters
- Multipurpose loggers: INTAB PC-loggers, Arduino-microcontrollers for special monitoring studies, GPS-logging
