AB  - This article provides information about the possibilities and technologies [2] available for the building industry in the Republic of Serbia, and concerns the trends - which expansion is expected in Europe and worldwide - the of use of renewable sources of building materials. Exploitation of sand and gravel from rivers and dry mines in many EU countries is prohibited. Excavation of clay from clay deposits and blasting the rock mass are considered as a violation of the natural environment and resulting with scars on our planet Earth.Renewable sources of construction materials are considered materials which each year can be renewed and which are the most common by-product of agricultural production.Materials obtained by recycling existing materials already used in construction, as well as by-products of industrial production are also considered sustainable materials.Renewable materials are supporting the new, worldwide trend in building industry, called "Green Building" with the aim of reducing harmful CO2 emissions.This paper will discuss renewable materials obtained as a by-product of agricultural production such as grain straw (wheat, barley, rye and oats), cane and hemp shiv obtained by mechanical breakingof hemp stems.These materials are cheap because they are by-products and they are energy efficient, which is particularly important nowadays.The construction of buildings with the above mentioned materials should be well planned to ensure the durability, fire resistance and particularly the pleasant and comfortable stay for the people.The walls made of this material must be solved, and ensured to avoid occurrence of rodents and other pests that may be carriers of dangerous and contagious diseases.

AB  - This article provides information about the possibilities of design and construction floor slabs concerning three very important aspects: the capacity, safety and energy efficiency.Nowadays, in the Republic of Serbia exclusively solid concrete slabs are designed and built,which are at least 20cm thick.The justification for this solution is to obtain, in its plane, a rigid plate-diaphragm that is able to endure seismic forces on the walls, proportionally to the stiffness of those walls.At the same time this solution has many disadvantages and it is a great load that limits the length of the span. That heavy load is directly proportional to the size of the seismic forces. The20 cm thick, solid concrete slab has a large heat capacity, and specific heat c (J / kgK), which are not energy efficient,as the warm air is accumulated, conductedtowards to the walls and also retained near the ceiling, while people are near the floor.There are other solutions of design and construction floor slabs that meet demands far more than a solid concrete slab.These are the reinforced concrete site-cast waffle slab.These slabs are extremely stiff and stable, optionally in both directions and can have a reduced mass up to 50% compared with solid concrete slabs.The authors will introduce one waffle-slab solution of reinforced concrete slabs, which satisfies, in addition to above mentioned, even the energy efficiency demand. It is a solution by Stirofert-technology built with structural expanded polystyrene as a stay-in-place formwork during the phase of concrete pouring and construction. This same stay-in-place formwork is a powerful insulation on ceiling with a preventing effect against heat-accumulation and heat losses towards the walls; same time equalizing the temperature of air near the floor and ceiling.
