Building and Environmental Technology

The Department for Building and Environmental Technology pursues teaching and research in the construction of buildings, bridges, dams and waterways with regard to their function, safety, environmental effects and durability. Its activities cover a broad field, from the melting of snow and flooding of regions, via houses, bridges and conduits, down to the material scale and the formation of cracks in concrete, and from thousand-year-old transport of pollutants in ground water to the rapid development of fire in buildings.
The department is responsible for most of the teaching for the programmes in Civil Engineering, Fire Protection Engineering and Risk Management, and a considerable part of the programme in Environmental Engineering.

Research is made in the following areas:

Building Materials

Researchers in Building Materials study the properties of various materials and their behaviour in different applications. The strength, durability and environmental effects are determined and applied in assessments of the material’s lifetime, recycling and indoor air quality. The material studied most is concrete, but other materials such as timber and masonry are also studied.
Keywords: concrete engineering, brick, calorimetry, wood, timber, moisture, damp, fracture mechanics, fracture processes, repairs, indoor environment, damage assessment and repairs, drying of construction damp, material decomposition, transport processes, plaster
 

Building Physics

In Building Physics, studies are carried out on how heat, moisture and air are transported through whole buildings and the various components of buildings. The results of this research are used to develop structural elements such as foundations, outer walls, windows and roofs. The aim is to create energy-efficient, damp-proof houses with a comfortable indoor climate.
Keywords: heat and moisture transport, indoor climate, healthy houses, energy use
 

Building Services

In the field of Building Services, engineering solutions are developed so as to ensure a comfortable climate in buildings (ventilation, heating, cooling, regulation). A holistic approach is used which means comfort, energy efficiency, good air quality, and systems and materials that are durable throughout their whole lifetime.
Keywords: indoor environment, indoor climate, energy use, life-cycle analysis, comfort
 

Fire Safety Engineering and Systems Safety

In Fire Safety Engineering  research is carried out into fire safety in buildings, and the probability and consequences of various kinds of accidents. The development of fires, human behaviour in the case of fire, methods and means of extinguishing fires, and vulnerability analysis of critical infrastructure systems are studied. Research is also performed in risk and safety management.
Keywords: fire, fire engineering, fire development, extinguishing agents, risk analysis, environmental effects, rescue services, evacuation safety, risk management by local authorities and in society
 

Structural Engineering

Structural Engineering is concerned with the design of load-bearing systems in buildings, bridges and other constructions to ensure safety and endurance. Durability, safety and risk assessment are central issues. Research is carried out in concrete, timber and brickwork structures, as well as computer assistance in planning and construction.
Keywords: reliability, large constructions, concrete, wood, timber, brickwork, masonry, CAD, durability and safety of constructions
 

Water Resources Engineering

In Water Resources Engineering, research is pursued in water resources and how water resides and is transported in nature and in urban systems. Studies are carried out on the movement of rainwater through land and foundations, how rain and melted snow reach rivers, flooding and the design of systems to reduce the consequences of flooding, as well as on water flows, the spread of pollutants, and erosion along coasts and the banks of (rivers and lakes). The research is of international character, and takes place in collaboration with many researchers and projects around the world.
Keywords: erosion, runoff modelling, ecological systems, environmental impact and protection, fractal processes, geochemical variability, incineration techniques, mixer-induced circulation, paleolimnology, remote sensing, flood control, hydrodynamics, hydrology, climate, coastal protection, soil, sediment transport, snowmelt, water, waves
