PhD project In Sweden, large databases of building characteristics and energy use are becoming more widely available across the buildings industry, indicating the potential use of data-driven approach for offering tailored energy efficient measures. The overall purpose of the research is to support the stakeholders in taking decisions in order to achieve sustainable energy renovation in detached-houses.
The purpose of the project is to support stakeholder engagement in the transitions towards sustainable energy renovation in detached-houses. Thus, data from Swedish Energy Performance Certificates and Swedish National Land Survey will be transferred into a database, which together with machine-learning algorithms are integrated into a platform that extracts case-specific knowledge regarding installed energy system, and actual energy use of buildings. This enables stakeholders to compute energy saving of alternative energy solutions tailoring their specific building physics.
Detached-houses (One and two-family houses owned by private owners) constitute more than 50% of the Swedish housing stock and are responsible for 12% of the total energy consumption in Sweden (Swedish Energy Agency 2017). About 80% of those houses are more than 30 years old, with low levels of thermal insulation, and seldom have ventilation system with heat recovery (Boverket 2015). A survey conducted by Boverket (Swedish National Board of Housing, Building and Planning) identified, among 821 detached-houses inspected, a substantial part of them need to be renovated to incorporate energy efficiency measures (Boverket, 2010). Ageing of the existing detached-houses, therefore, provides a unique opportunity to engage in the transition towards a sustainable energy system.
