Energy efficiency of residential buildings

The problem of energy sustainability, both from an environmental point of view, and from procurement and production costs, has long been present in many academic, professional and socio-political fields. In view of this, as early as 2008 the European Parliament had approved the so-called “climate-energy package, target: 20, 20, 20”, and previously the national legislator had foreseen various initiatives and important facilities, in particular in the form of deductions tax for interventions aimed at the energy efficiency of buildings. More recently, with Directive 27/2012, the European Parliament has established a common framework of measures for the promotion of energy efficiency in the Union and in Italy national energy strategies have been established, placing energy efficiency as the first point. Some of the places where it is possible to achieve important energy savings, through interventions to reduce heat loss and with greater efficiency of air conditioning, are buildings. Therefore intervening on the energy requalification of private and public buildings is a priority of concrete intervention. The actions carried out so far have concerned in particular the new buildings, and only very partially the existing ones, mostly with replacement of the fixtures which, as is known, do not in themselves give the best contribution to reducing the heat loss of the houses .

In Italy there are 13,800,000 buildings, of which 12.2 million are used for residential use, 80% of which are owned by families; more than 90% of these buildings would require energy efficiency measures. Given the necessary proportions, you can guess what role families can play to achieve the goal of reducing energy waste. Taking into account that these interventions, thanks also to public incentives, have a return in the short / medium term of the investment, all families can reap real benefits both of an economic nature, of micro-environmental comfort, and of enhancing the property. Important benefits are also determined for the local economy, for the environment and also the dependence and costs of importing fossil energy products are reduced.

It would therefore be desirable to develop various initiatives as soon as possible to stimulate families to invest in their home in the direction of energy efficiency, to make them aware of the opportunities, of the possibility of carrying out an intervention that over time will prove profitable and useful for everyone. These initiatives should be implemented, through an extensive communication and awareness program, above all with innovative means and with a character different from traditional advertising, as here it is not a question of advertising a brand or a product; in our case it is an important expense commitment that is normally considered for a long time by families and is internalized with a more complex and complex choice and possibly decided through a cultural conviction, interest and perspective. The commitment should therefore be to direct, inform and train, as well as assist and protect families who intend to invest in the direction of energy efficiency of their home.
