In our country the culture of technical planning for building projects is not widespread; this fact is connected to the lack of technical capacities among our purchasers. This problem often presents itself in the initial planning phases when faced with aspects of purely functional-technical and economic planning. Some administrations try to deal with this problem, which has a major impact on the quality and effectiveness of the works carried out as regards the needs of the users, by means of “system programming”, in other words by the definition of systems of general rules of behaviour or direction to solve problems which are of such a repetitive and widespread nature as to have an impact on building activities in entire sections. The diffusion of guidelines for the sector or codes of good practice, of unified protocols or technical recommendations, allows public bodies to exercise, in line with their technical and economic resources, the functions of controlling and directing public building activity towards strategic sectors such as social housing, student residences, health and school buildings, while also having a significant impact on private building. Many local administrations are equipping themselves with codes of practice for constructing or adapting social housing, aimed at the qualification of building activity in a sector which has enormous weight in terms of construction in the area and its impact on energy consumption and the wellbeing of the inhabitants. High environmental quality and encouraging the wellbeing of the inhabitants have an absolutely central role in these support tools for drawing up and planning interventions; furthermore these instruments have the role of incorporating all the indications and requirements of local and national building regulations which cover the various aspects of construction, above all, implementing those aspects regarding energy conservation or the optimisation of those elements relating to widespread environmental quality. In this way, alongside the traditional indicators for technical norms relating to residential building, can be placed a system of best practices, innovative suggestions for the environmental quality of projects regarding the energy and environmental functioning of sites and buildings, and on the knowledgeable use of technological solutions aimed at an overall improvement in the uses of the building and its urban context.
