Energy Saving Measures in Existing Swedish Buildings: Material for a book to be published by VVS Företagen
2011 (English)Report (Other academic)
Energy efficiency in existing buildings is a primary concern for the European Union and Sweden in fighting climate change. To achieve the 20% energy reduction in buildings target by 2020, the broad base of building owners must understand the technical and financial benefits of choosing energy efficient upgrades when renovating their properties. This report is a technical supplement to the upcoming publication by the Swedish HVAC industry organization VVS Företagen, which seeks to inform their customer base about energy efficiency. Nine common Swedish apartment buildings from 1945 up to 1985 have been modeled in Design Builder building energy modeling software, with three energy saving packages applied. The energy saving packages represent a decision to choose more expensive, but more energy efficient equipment that can be installed during routine renovations. In each case, the data reported are total annual energy usage, heat balance, accumulated cash flow over a 40-year period and the internal rate of return for each package. The technical and financial performance of each building varies significantly depending on type, but most packages on most buildings have an IRR greater than 5%. While the results displayed here cannot directly represent a specific building, the data is a good resource for owners to understand what performance they can expect for their specific building. The technical information reported here is appropriate for the VVS Företagen publication.
