Sustainable development is a conceptual basis in almost all areas of the social and economic life, encompassing during the past decade an increasing number of aspects, the construction sector being among these. In the construction fields, the concept of sustainable development has been developed out of the definition provided by the Ch.Kilbert International Conference on Sustainable Constructions, held in Tampa Florida in 1994: "the creation and responsible management of an effectively-built environment based on the efficient use of resources and environmental principles." Nowadays, sustainable development in constructions can be defined as "developing buildings of ultimate quality with the lowest possible impact on the environment" (Ligny, 2009). At the EU level, it is estimated that the construction sector utilizes about 40% of the overall energy produced and generates around 40 % of total waste, buildings being considered responsible for more than 40 % of emissions of greenhouse gases. The notable Sick Building Syndrome has highlighted a number of factors that affect the health of habitants, related to: germes and allergens factors, improper temperature and humidity, molds, dust, improper lighting, ventilation and air currents, noise, the presence of building materials that contain harmful substances or generate toxic emissions, the operation of some equipment. Together with other factors, these may be found in the case of social housing buildings with high occupancy rates and relatively low living standards. This paper analyzes the situation of such buildings thermally rehabilitated with the support of European funds, highlighting measures to improve their current setting. Comparing the results obtained in case of a building prior to its thermal rehabilitation with the results after its rehabilitation, we identify the probability of risk factors specific to human habitat. An important conclusion of the paper is that the thermal insulation and energy efficiency of a building cannot be limited to interventions in the building’s surface and facilities, the natural room ventilation becoming an essential factor. This paper presents a study with the aim of providing the possiblity of creating this in an apartment.
