PRECAST SANDWICH PANEL – INNOVATIVE WAY OF CONSTRUCTION

In the period of Global crisis, construction industry is one of sectors that have suffered the most. It is evident that new ideas, new approach in design of structures and the use of “green” construction materials together with environmental awareness will result with revival of construction market and economic recovery. Existing buildings are responsible for more than 40% of global energy use, i.e. in Croatia 83% of buildings consume from 150 to 200 kWh/m2/a just for heating. It’s obvious that future of civil engineering are, not only low-energy buildings, but whole low-energy cities. The construction sector consumes vast amount of natural resources and produces significant quantity of construction and demolition waste (CDW). A proper CDW use leads to efficient and effective use of natural resources and helps mitigate the environmental impacts to the Planet. The Waste Framework Directive requires Member States to take necessary measures to achieve a minimum target of 70% (by weight) of recycling CDW by 2020. The fact that in most European countries disappointingly small percentage of CDW is being reused, illustrates the possibility of expanding a construction market in Europe by reusing CDW for new ‘’green’’ materials. Concrete, as one of the most used construction materials, can be used to produce energy and resource efficient products. Based on these facts, this paper represents one solution for the Period of Economic Recovery: ECO-SANDWICH® - an innovative ventilated prefabricated concrete wall panel with integrated Ecose® mineral wool insulation. It allows very low energy design and retrofit of buildings, reuse and recycling of CDW (all in accordance with 6th and 7th Basic Requirement for Construction Works). It resulted from collaboration between academic community and construction industry and on principles of ‘’turnkey’’ construction provides user a high quality, affordable, energy saving and aesthetically attractive concrete building.
