This paper presents the results of studies that analyzed eco-efficient solutions for homes adapted energy-wise to the specific demands of the mountain climate (climatic areas III and IV of Romania), which ensure meeting the standard parameters and the conservation of the building traditions in these areas. This paper presents the results of the analytic assessment of the global loss of heat for an actual house built in a mountainous area at an approximate altitude of 850m (M1), monitored for its thermo-physical properties by on site measurements in comparison with a building having an identical spatial structure with energetically efficient closing elements, studied experimentally in the laboratory. The paper presents comparative results of these studies for the examined buildings as follows: * the thermal transfer resistance of the exterior walls; * the total heat loss of the entire building; * the global heat loss for a built cubic meter; * the global heat loss through the entire surface of the opaque exterior walls; * the global heat loss for a square meter of opaque exterior wall. The final result of this study has been a Catalog of solutions for ecological and energy- efficient homes adapted to the mountain climate, which is useful in ensuring a durable development of human settlements.

Roads networks have a major impact on terrestrial ecosystems and on human life quality so there is an imperative need for a new approaching regarding system sustainability. "Green" transport infrastructure that underline energy efficiency, reduce costs to roads users and government should be planned, used, and monitored with sustainability in mind. Over recent years, a number of methods have been developed to evaluate sustainability of roads projects, including ratings systems and different evaluation schemes. The aim of this paper is to highlight new frameworks in order to understand the recent needs for sustainability, comparing technical and environmental properties and their contribution to roads infrastructure durability and sustainability.
