Powerful tool for building geographic analysis

Published: 30 November 2016

Tim Johansson, PhD in Construction Engineering at Luleå University of Technology, is working with the 4D visualization. He has developed a powerful tool for geographic analysis regarding the need for renovation and energy efficiency of apartment buildings.

The National Board of Housing, Building and Planning and the Swedish Energy Agency are working with the basis for the Swedish renovation strategy. Tim Johansson, LTU, and Mikael Mangold, Chalmers, has been contracted to develop building-specific data on Swedish housing.

"The purpose of the delivery is to estimate renovation costs and energy efficiency potentials in the Swedish housing stock more through analysis of available building specific data", says Tim Johansson.

The mission carried out by importing data from the Land Registry and energy declarations which are then integrated by methods developed by Tim Johansson. Calculation models developed in Mikael Mangold's dissertation is then used to estimate completed renovations that have been made and what renovations are anticipated in the future where even the energy efficiency of buildings is calculated.

"Unlike many other missions of this kind, we have used the extensive building specific data covering more than 205 million square meters of heated area", says Tim Johansson.

The project Energy and renovation atlas is funded through the research programmes Alice and Siren.
