RentalCal addressed the building sector with its great potential for reducing CO2 emissions by means of energy efficiency investments. The RentalCal project offers a new approach: Based on the European Union EPBD (recast2010) the “cost optimal level” for minimum energy performance requirements, the rental housing sector is considered. RentalCal broadened the financial perspective from owner-occupier to the wide range of professional and non- professional landlords.
As for the profitability related to energy efficiency investments the analysis of upfront costs and the resulting financial benefits (for the investor reflected in higher rental and/or sales premiums and lower vacancy risks, for the tenant in increased energy savings), was prominent for the development of the RentalCal web based tool. Keeping this in mind RentalCal aimed at three objectives:
1) To develop a standardised methodology for the profitability assessment of such investments
2) To provide transparent and comparable information on the prerequisites of such investments given in the beneficiaries’ states, including a cross-country comparison and
3) To raise the awareness and spread the knowledge of the importance of “green values” connected with energy efficiency investments.
These overall objectives have been translated into the RentalCal web based tool, a “tool to talk” in order to strengthen the dialogue between housing sector, consultants and financial market actors in the private sector, with an emphasis on the different categories of landlords.
Investing into energy efficiency is of investors’, tenants’ and society’s interest: RentalCal represent housing markets from eight EU member states (Czech Republic, Denmark, France, Germany, Great Britain, Poland, Spain and the Netherlands). These markets comprise a huge share of the EU’s largest rental housing markets with about 33 million dwellings and the private rental sector, with about 46 % of it built in the 1980s or earlier, offerings great potential for energy efficiency investments and contributing to energy saving and CO2 reduction.
