Spatial Quality Indicators for Energy Renovation of Residential Buildings
MetadataShow full item record
This paper consists of the conclusion of the first part of the on-going PhD research: the crossing between spatial quality definition on building scale, energy renovation measures and building performance assessments. The current paper presents the results of a search for and an evaluation of available indicators that best represent perceived spatial quality, with particular weight on energy renovation. The results of the analysis of the available spatial quality indicators show a significant potential for improvement of the indicator’s basic scientific characteristics (validity, specificity, sensitivity and reliability) in assessing spatial quality. That is the indicators on spatial quality are entirely to be developed. Improved spatial quality gives decision-makers, politicians and building owners solid argumentation for increased investments in energy efficiency, making a highly visible contribution to the attractiveness and public image of a building block, as well as people’s every-day life, well-being and health. This is, however, only possible if objective, measurable spatial quality indicators, assessment and design methods are available for decision-making. By stressing the architectural and user value of energy efficient renovation, this research thus aims to contribute to widespread implementation of energy efficiency goals in building performance assessments. This paper forms part of PhD research project “Definition, Assessment and Implementation of Spatial Quality Parameters in Energy Renovation of Residential Buildings”, aiming to contribute to decision-support for the design of energy-efficient built environments with high spatial quality. The main aim of the PhD is to propose a clear definition of spatial quality to be considered in energy renovation; and to develop practical indicators to assess spatial quality parameters on building scale. Keywords: spatial quality indicators, energy efficiency, building renovation, residential buildings, building performance assessments.
