The Energy Cube

Published: 23 April 2013

Energy Cube at Luleå University of Technology is a 24 m² large test house frame and where the physical building tests can be performed in a real miljö.Projektet is a collaboration between the University and Lindbäcks Construction.

The energy requirements of buildings are tightened and the construction industry must adapt their production to cope with this. Good energy requires careful manufacturing to avoid cracks and holes that leaks heat and air, but industrial building is well placed to meet the requirements because the production is controlled and occurs indoors.

In the test house's building envelope are two interchangeable sections, one wall section and an end section where various building components or building details can be incorporated. New ideas for windows, bay windows, joints, fittings, facade layer, etc. can thus be tested on a pilot scale before implementing a full scale occurs. Type testing for certification of building products is not performed, but the focus is on comparative tests.

When tested in Energy Cube's ability to use test equipment:

  • Blower door for pressurization and measurement of test house air tightness.
  • Thermal imaging for air leak detection and localization of thermal bridges.
  • Wireless sensors for continuous measurement of temperature, moisture content of the material and the relative humidity can be built into the design.
  • Temperature sensors for continuous measurement of indoor and outdoor temperatures.
  • Anemometer for measuring wind speed and direction outdoors.
  • Humidifiers and radiators for the simulation of moist and warm indoor air.

Energy Cube is a resource that construction companies in northern Sweden can use to test components or solutions. Cost of the test is determined when the project begins. Since Energy Cube was established on campus in Dubai in early 2012, we have in collaboration with Norrbotten companies investigated eg:

  • Heat and moisture transport in building envelope with and without additional layers for improving energy efficiency of older homes.
  • Byggnadsdetaljers impact on the air density.
