Measures and steps for more efficient use of building space and energy use

This feasibility study initiates a discussion on how digitalization can affect the demand and supply of heated space in the built environment, by introducing space sharing services. It also explores new ways to measure energy use based on activity instead of per square meter, and how a quantification of the potential reduction in energy use due to more efficient use of space could be made. 

Based on ideas to encourage flexible use of buildings, facilitated by digitalization, and new measures of building energy use, we propose an order of priority:

  • Reducing the demand for space

  • Reducing the demand for space

  • Intensify the use of existing space

  • Reconstruct, given the first two steps

  • Designing new buildings considering the first two steps
