ONLINE BRUSSELS HERITAGE - ONE-DAY SEMINAR - 11/12/2014 PRESENTATION AND RESULTS OF THE "PLAGE" PROJECTS LOCAL ACTION PLANS FOR ENERGY MANAGEMENT EMMANUEL HECQUET CICEDD, NAMUR. HE HAS BEEN WORKING IN PARTNERSHIP WITH BRUSSELS ENVIRONMENT ON THE IMPLEMENTATION OF THE "PLAGE" PROJECTS SINCE 2006 THE GOAL OF THE PLAGE PROJECTS IS TO IMPROVE ENERGY EFFICIENCY IN BUILDINGS IN THE BRUSSELS REGION IN ORDER TO ACHIVE ENVIRONMENTAL AND COST SAVING BENEFITS THROUGH THE IMPLEMENTATION OF PROACTIVE ENERGY CONSUMPTION. SIGNIFICANT RESULTS HAVE BEEN ACHIEVED SINCE THE LAUNCH OF PILOT TESTS IN 2006. The regulatory background to the programme of Local Action Plans for Energy Management (PLAGE) is the European Directive 2012/27 on Energy Efficiency and the implementation of that directive throughout the Region, imposing a reduction of 30% in greenhouse gas emissions by 2025 compared to 1990 levels. OBJECTIVES AND METHODS USED FOR THE PLAGE PROJECT The goal of the PLAGE project is to manage energy consumption with a view to reducing it. It targets managers or owners of large building stocks, as well as occupants, encouraging them to take actions that will produce rapid results. The programme includes pilot tests and will take place over three to four years. The project primarily focuses on rationalising energy use, application of regulations and insulation of boiler installations than on making heavy investments. We therefore try to optimise consumption with a priority on heating and (to a lesser degree) on electricity. This programme applies to existing buildings, not to new buildings or buildings that have been the subject of extensive renovation works. We used a specific process quality method or ISO, namely the Deming Wheel (fig. 1). This is a continuous improvement process. PLAGE focuses first on energy accounting, or more precisely what we call the "energy register", as well as an administrative and technical inventory of the building stock. This first stage may be laborious depending on the number of buildings. In the municipalities where the PLAGE project was launched in 2006, the mere creation of a register (involving up to 100 to 150 buildings) took some time. The objective is to identify "priority" buildings: those 94 | Presentation and results of the "plage" projects that offer the greatest potential for energy savings for the lowest cost. This is followed by a three- to fouryear action plan involving the close monitoring of energy consumption. We analyse the initial results of this energy accounting process, evaluate them and then carry out corrective measures where necessary. The register and the action plan are then updated and a new cycle begins. The idea is to enter a virtuous circle for improving the energy consumption of the building stock. The preparation of the action plans allows us to draw up an outline of the technical and energy aspects of each building. The priorities are always low-cost measures (e.g. management of boiler installations, rationalising energy use (RUE), and generating awareness among the occupants or training technical services). We then analyse the results and energy consumption month by month, year by year, to see if
