The aerogel is a nanomaterial that may represent a viable alternative to the traditional thermal insulations, especially when it is required an increase of the thermal performance of the building envelope elements and also a reduced thickness of their finishing layers. The paper presents the conclusions of some studies regarding the thermal behaviour of the aerogel and also some improvement possibilities of this material and of other materials, by integration of the aerogel in their structure. At the same time, th...

The present paper analyzes - from the point of view of the energy consumption - a residential building in Romania, of usual construction, in order to fit it into the energy certification grid for heating [1]. The study was conducted for 8 thermal insulation variants with a thickness between 5 and 40 cm, each in 3 ventilation cases, in a total of 24 cases [2]. In order to determine the energy performance of the building, the CIMPSPAT expert calculation program was used [9], with the high-precision numerical method ...

A better energy efficiency of a building can be obtained by implementing passive and active energy efficient design strategies. The initial design phase starts with implementation of several passive strategies, i.e. strong thermally insulated building envelope, buildingпїЅs orientation, windows placement, and buildingпїЅs aspect ratio, window to wall ratio, use of thermal mass, natural lighting, shadings and other solutions. However, looking at how building are designed, built and operated nowadays, it can be obse...
