On the one hand, it is proposed to replace all fluorescent tubes and discharge lamps with electromagnetic ballast existing in municipal buildings with LED technology luminaires. This action will result in high energy savings, resulting in a reduction in greenhouse gas emissions. _x000D_ is also proposed to replace the existing diesel boilers in municipal sports centres, many of which were installed more than twenty years ago, with natural gas condensation. For each of the centers on which action is taken, this measure will include the realisation of the connection and the adaptation of the boiler room._x000D_ It is also proposed the renovation of the air conditioning equipment in the municipal buildings, since a large part of the air conditioning equipment, has a high age, which means that they are built with an inefficient and highly polluting technology. These devices, for the same level of comfort, consume more energy than appliances belonging to the new generation which, using less polluting gases, are more efficient.
