CASE STUDY.The first was the introduction of interest-free loans for qualifying energyefficient building projects, from early April 2009. Such loans are available for house renovation work to reduce both energy consumption and the emission of greenhouse gases. The loan is granted for certain types of work (such as project management and energy consumption assessments, insurance fees, etc.) or for any work involved in and inseparable from energy efficiency improvements and installation carried out by a professional. This latter category includes the installation of new windows, including triple-glazed windows. Specific conditions must be met to qualify for such a loan (concerning the age of the house, the grant of any previous loan, the amount of the loan, repayment schedule, etc.) These loans rapidly became popular: by late July 2009, 15,000 applications had been received, and by the end of March 2010, more than 100,000 loans had been granted. The second measure introduced were training schemes for companies and craftsmen, to encourage them to take into account the energy performance of buildings. Since its launch in 2008, over 10,000 workers have been trained under this measure. Following this market trend, MPO Fentres has obtained certification, allowing the company to showcase its commitment to sustainable development, from product design through to its installation. MPO Fentres highlights its long-term commitment by ensuring that the joinery products it sells are environmentally-friendly. MPO Fentres maintains its commitment to the continuous improvement of its products, including products with triple glazing, which allow an increase in performance of over 40% compared to the best double-glazing on the market. This commitment is reflected in all companies' activities, as stated above, but MPO Fentres has also improved its installation and waste treatment along ecological lines, including waste recycling. In other words, since 1 March 2007, MPO Fentres has committed itself to producing more eco friendly windows, offering NFcstBat-certified eco friendly windows and triple-glazed Visio windows. As such, MPO Fentres puts the most efficient windows in terms of thermal insulation within reach of everyone. The company decided to concentrate on this market sector, which, according to the company's CEO, represents the future of the company. Noting that for an average surface area of 50 to 100 m2, 10 to 15% of heat loss from dwellings comes from windows, it appears that they are an important element that could improve the overall energy performance of homes. Indeed, these windows have become the ideal solution in terms of domestic thermal insulation.
