To address the global energy problem, energy from the solar source remains the most encouraging solution for buildings with a difficult-to-achieve goal such as achieving zero net energy consumption. In a solar thermal system, integrated solar collectors in buildings can convert the absorbed solar energy into thermal energy and can be better exploited in an area of the facade, while acting as an integral component of the building envelope, with good sun exposure. The aesthetic character and functionality of this te...

Currently, many researchers around the world have been focused on applying existing natural resources beside artificial and agricultural waste in RCC mixtures for dam construction to improve the properties of the resulting concrete, produce a greener RCC, and therefore, to protect surrounding environment. The aim of this experimental study is to estimate and compare pozzolanic activity of some active mineral additives used in roller compacted concrete for dam construction by using saturated lime solution method. T...

Sustainability is a criterion defined since the 1980s, essential in all areas of activity, without which development cannot be acheived. Thermal insulation mattresses produced using sheep wool, successfully meet the conditions imposed by this criterion. This type of building material ensures the responsible use of non-renewable natural resources, the possibility of reuse and recycling of materials, contributes to environmental protection and pollution reduction, energy saving and provides a hygienic and healthy li...

In remote, hard-to-reach areas, renewable energy resources such as the sun or wind are available and can be used to produce green electricity at competitive prices. The disadvantage is that we do not always have the source of energy available (sun at night or continuous wind). This disadvantage can be overcome by using hybrid combinations of two or more renewable energy sources together with the storage of the energy produced, thus ensuring the supply of electricity at very good performance levels and with low cos...

In the current global context where we talk about the depletion of conventional fuel resources and their impact on the environment, we find that it is necessary to integrate renewable energy sources/resources in new constructions, but also adapt existing constructions in order to reduce energy consumption. This article presents a system with solar thermal collectors combined with PCM phase change materials. During operation, some of that thermal energy may be diverted to a storage system where it is maintained for...
