TY - GEN A1 - Hirschl, Bernd A1 - Großmann, Doreen T1 - Influence of rebound effects on the achievement of energy saving targets after an increase in energy efficiency on non-residental buildings T2 - Bulletin of Prydniprovs’ka State Academy of Civil Engineering and Architecture N2 - This article draws attention to rebound effects, which are responsible for missing the planned energy savings after an increase in efficiency. For residential buildings wide scientific studies to rebound effects after a thermal retrofit already exist. This article presents first findings to rebound effects in non-residential buildings. It presents a methodology for the determination of rebound effects and their causes in non-residential buildings. In addition to the mathematical calculation of the rebound effects semi-structured-interviews to identify the causes were conducted. This article focuses on four office and administrative buildings with regard to their actual and calculated building heat pre- and post-thermal-retrofit consumption and comes to the conclusion that even in non-residential buildings rebound effects are to be expected. However, the causes differ significantly compared to residential buildings.

The imperative to reduce their energy consumption is widely accepted in EU countries. It is now common to upgrade both residential and non-residential buildings to increase energy efficiency, but studies indicate a significant gap between energy performance and design. In the residential sector, this gap has been extensively investigated and quantified under the heading of the ‘rebound effect’, but there do not yet appear to be studies on rebound effects in non-residential buildings. This paper develops a methodology to fill this gap. Through technical measurements in four recently retrofitted German public service case study buildings, rebound effects were estimated under two definitions: the ‘elasticity’ rebound effect and the ‘energy performance gap’ (EPG). Cross-sectional data of actual and calculated consumption in 176 comparable buildings was used to estimate typical rebound effects which could be expected in such buildings. The case study results indicated comparatively low rebound effects but high EPGs. Semi-structured interviews with building occupants and operators identified credible determinants of energy consumption. The methodology proved effective and robust, and is offered for further use and development.
