In-depth renovation of housing blocks

Project - In-depth renovation of housing blocks

Energy renovating housing blocks to low-energy class 2015 and building class 2020.

PSO-project

Project start: 1 March 2015. Ended ultimo 2018.

Purpose of the project

The purpose of the project is to develop a guidance for optimizing energy conservations, economy and CO2-reduction by renovating to low-energy level starting from two concrete housing blocks.

Content

Focus is on prefab constructions from the 60's and 70's together with brick constructions. The starting point is two concrete renovation cases: Traneparken (picture) and Sems Have, where the renovation is conducted in two different ways:

  • Traneparken with external re-isolation at almost low-energy class 2015 level
  • Sems Have with a completely new building envelope at building class 2020 level

Both buildings have new ventilation systems, PV-system and better utilization of the day light installed.

The project consists of the following work packages:

  • WP1: Documentation of energy conservation and indoor climate in both buildings
  • WP2: Construction and calibration of a model of each of the buildings, before and after the renovation by using the ASCOT/BYGSOL programme
  • WP3: Parameter variation with ASCOT/BYGSOL of the models to investigate alternative renovation initiatives
  • WP4: Development of a guidance for in-depth renovation of housing blocks in the light of the results from WP1 and WP3
  • WP5: Presentation of the project's results

Participants

The project is carried through as a collaboration between Statens Byggeforskningsinstitut, Teknologisk Institut, Cenergia Energy Consultants and Boligselskab Sjælland.
