ONLINE BRUSSELS HERITAGE - ONE-DAY SEMINAR - 11/12/2014
(some buildings are used for music classes or sports activities during the evening or at weekends). It is just common sense, however, that the temperatures should be lowered considerably during school holidays; however, in reality even this is far from evident because the cleaning team are present at times and various activities take place in the school holidays. Reorganising everything may take time and may present numerous obstacles for the Energy Manager. These changes cannot be carried out from one day to the next. In this school we lowered the temperatures during the night, replaced the outer doors, regulated the thermostat valves and trained occupants to use them effectively.
In the end fuel consumption fell by 24%, but at the same time electricity consumption rose sharply for the same reasons mentioned above. We did not tackle this problem, and there is a lot of work for the Energy Managers to take up here. However, we noticed that in spite of this increase, we still achieved an energy saving of 22,000 euros over all the energy vectors.
CONCLUSION
These examples show that the public sector can set a strong example for other sectors. The goal of Brussels Environment is to encourage demand and improve services via a number of specific actions such as training programmes, seminars and pilot projects like PLAGE, in order to improve energy efficiency in the building stock. In view of the results already obtained in previous and current PLAGE projects, thanks to an efficient methodology that requires minimal financial input, the programme has been made mandatory for building stock in the private sector with a surface area of more than 100,000m2 and more than 50,000 m2 in the public sector, as part of the Brussels Air, Climate and Energy Code (COBRACE). This next compulsory action for major blocks of building stock is an important stage in reaching our objectives to reducing consumption.
