Post-Occupancy Evaluation (POE) is defined as the process of systematically comparing a building's actual performance measures with explicitly stated performance criteria. POE is widely recognised as being central to addressing the performance gap between design intentions and the actual...

Despite a common EU directive on energy efficiency in residential buildings, levels of energy efficiency differ vastly across European countries. This article analyses these differences and investigates the effectiveness of different energy efficiency policies in place in those countries. We...

The building sector plays a major role when it comes to meeting climate targets. An analysis by DIW Berlin based on data from energy provider ista SE shows that in the past two years both the temperature-adjusted heat consumption in German multi-apartment buildings and the temperature-adjusted...

Municipalities in Germany develop policy plans referred to as 'Energetische Quartierskonzepte' (EQ, pl. EQs) to lower and decarbonize the energy consumption of existing buildings in whole city districts. These EQs describe the status-quo, a strategy, and measures for the energy-related...

The poor thermal performance of prefabricated house roof in severe cold area results in the increase of heating energy consumption and uncomfortable indoor thermal environment. Roof energy-saving retrofits are necessary, and the specific retrofit measures are investigated from the perspective of...
