Score - Sustainable Construction in Rural and Fragile Areas for Energy efficiency
Guidelines for Integrated territorial Planning:
Solar thermal collector
Portugal, specifically the south, constitutes the point of view of the existence and availability of solar energy, an area of excellence, where every year there are about 2200-3000 sunshine hours, which equates to 14-17 MJ / m2/day.
Portugal is a country with Europe's biggest solar resources, in which are strong advantages of the installation of equipment for water heating from this renewable energy resource. In this context, the National Action Plan for Energy Efficiency (Portugal Efficiency 2015) provides for measures to boost the solar thermal in Portugal, dedicated to the residential and services sectors, which create favorable conditions for the acquisition of equipment and overcoming the barrier of initial investment.
Between March and December 2009 held the Solar Thermal Program 2009, a solution "key-in-hand" with special conditions for the purchase of solar panels on the part of consumers, developed by the Ministry of Economy and Innovation (MEI) and Ministry of Finance and Public Administration. During this period, in association with the Ministry of Labour and Social Solidarity and the Ministry of Youth and Sports, conditions were developed to extend the Solar Thermal Program 2009 to private social solidarity institutions (IPSS) and associations with sport utilities.
The submission of applications processes of the two strands of the Solar Thermal Program 2009 ended December 31, 2009. Were installed 50,158 solar thermal systems, brands from 55 members, representing an area of 197,730 m2 of solar collectors.

In the scope of this program, 2 leaflets were produced:

At the same time, occurred another program - Micro production, in which electric energy is produced through photovoltaic solar panels, which demand the installation of at least 2 m2 of thermal panels (or micro wind turbines). This increased the area of installation, but not enough to be considered a huge impact.
In Portugal, the main obstacle for the this kind of technology dissemination and global using among all families, are related to:
- Economic aspects – for a medium family, the initial investment can be high, although the investment could be easily returned in 3-4 years;
- Urban design – mostly in old and historical cities this can be a limit to the installation of solar collectors;
- The closed programs that weren’t reopened had a negative impact on consumers, once from a social point of view, those programs were the confirmation by the Portuguese state and energy institutions that the technologies had given proofs and were correctly dimension to all kind of families.
