Solar walls in Vibekevang - energy retrofitting; Solvaegge i Vibekevang - energirenovering

Technical Report:

Abstract

Vibekevang in Copenhagen, Denmark, is a collection of 96 architecturally attractive two-and-a-half storey buildings, in all 540 homes. The residents, stimulated by an active residents` association, are well integrated socially. This association took the initiative to instigate a ``greener Vibekevang`` and are interested in using renewable energy sources. Cooperation with the Laboratory for Thermal Insulation at the Technical University of Denmark resulted in the initiation of a project concerning the use of passive solar energy for space heating by covering some of the buildings` facades with glass. The solar wall consists of a solid non-insulated brickwork outer wall which is retrofitted to absorb and accumulate solar heat by using a covering of transparent insulation material and glass plate. An investigation of the architecture, building technology, energy savings and economy was carried out and is described in detail. The evaluation of the latter is based on measurements taken over a one-year period. Measurement methods and results are given. Residents were satisfied with the appearance of the walls. Rooms were not overheated except for a very short periods during heat waves. The solar walls were less damp than the original ones. Energy savings amounted to 936 kWh p.a. per flat, this could  More>>

A cost-benefit analysis shows that the payback period is long but are weighed up by the benefits. (AB) (10 refs.).}
