Acoustics comprise sound- and vibration aspects in buildings and constructions. Our core expertise is sound insulation between rooms and units, sound regulation and room acoustics, vibrations and noise from technical installations and vibrations in constructions.
Building and infrastructure Installations/HVAC
Energy efficiency and increased heating comfort has resulted in modern buildings being more airtight than previous building constructions. Tight buildings have reduced the uncontrolled ventilation, without this being sufficiently compensated through controlled ventilation. Both in existing and future buildings, it is therefore important to install ventilation plants that are satisfactory with regard to air flow rate, reliability, comfort, energy efficiency and usability.
Geothermal energy systems cover systems for both shallow and deep geothermal wells. Shallow geothermal boreholes, 50 - 200 m, are used as heat source or sink for heat pumping systems. Deep geothermal wells, typically 1-10 km, can retrieve heat with higher temperature. Heat with high temperature can be utilised directly, e.g. for district heating, or as a heat as source for running a heat-to-power cycle.
Installations for waterborne heating has been common in both commercial buildings and residences for many years. Such installations provide flexibility in the choice of energy source. Because of constantly stricter regulations regarding energy efficiency, modern buildings require less and less energy supply in the form of heat. One of the challenges in the future is effective operation of heating installations with low temperatures and small quantities of water.
SINTEF has laboratories for testing of all sanitary products. We provide information for consumers, insurance companies, the building industry and the authorities. We work continuously to influence society to choose solutions that are not subject to water damage.
Ground-Source Heat Pump Systems
Ground-source heat pump (GSHP) systems are an energy efficient technology for heating and cooling of non-residential buildings. Ground source is a relatively high and stable heat source temperature that enables a considerable share of the cooling demand to be covered by means of so-called “free cooling”. Installation of high quality GSHP systems therefore complies with the main goals of the new EU Directive on The Energy Performance of Buildings (Directive 2002/91/EC), i.e. reduction of the total primary energy demand and the associated CO2 emissions in buildings.
What about a wind turbine installed in your wall?
Researchers have been looking into the opportunities and possible drawbacks of exploiting small, so-called 'building-augmented' wind turbines (BAWT) in Norway.
