ENERGY EFFICIENT, RECYCLED CONCRETE SANDWICH FACADE PANEL


ECO-SANDWICH is a ventilated prefabricated wall panel utilising recycled constructiona and demolition waste (CDW) and mineral wool produced using innovative and sustainable Ecose® technology for reduction of primary energy consumption in building stock.

Innovative concreting solution of outer layer distinguishes prefabricated ECO-SANDWICH wall panels, from similar products and makes it unique on the market. ECO-SANDWICH represents improvement of existing prefabricated wall panel products, aligning itself with the mandatory targets of EPBD and EPBD II thus tackling the 20-20-20 targets, thus REPRESENTING A POSSIBLE TECHNOLOGICAL SOLUTION FOR FAST CONSTRUCTION OF VERY LOW ENERGY BUILDINGS ON A LARGE SCALE.

THE ECO-SANDWICH TACKLES THREE MAJOR ENVIRONMENTAL PROBLEMS: •

Reducing greenhouse gas emission by enhancing energy efficiency of buildings, and reducing embodied energy

Increased resource efficiency through the use of construction and demolition waste (50% of total aggregates is obtained from recycled aggregate) in panel manufacturing, and recycled glass in manufacturing ECOSE® mineral wool

Minimising the use of regulated chemicals like phenol and formaldehyde from the insulation material production process

SUSTAINABILITY CONSIDERATIONS In comparison to solutions that exist on the market, ECO-SANDWICH wall panels have superior properties and characteristics regarding lice cycle costs, achieving at the same time significantly lower environmental impact.

DESIGN FOR REUSE AND RECYCLING LOW EMBODIED ENERGY

The embodied energy of the ECO-SANDWICH is 33.8% lower than that of lightweight composite insulation panels. ECO-SANDWICH wall system has greater thermal mass reducing the need for heating energy by 2-15% and also smoothes out fluctuations in internal temperature thus reducing daytime airconditioning requirements by up to 50%, this, in turn, cut CO2 emissions. ECO-SANDWICH WALL PANELS ARE BOTH REUSABLE AND FULLY RECYCLABLE. ECO-SANDWICH ACHIEVES SUSTAINABLE, HEALTHIER ENVIRONMENT AND LIVING AMBIENT FOR OCCUPANTS. By using recycled CDW in combination with mineral wool produced with Ecose速 Technology, constitutes an innovative product whose embodied energy payback time is 22 months due to savings during exploitation.

ENERGY EFFICIENCY Buildings are one of the greatest consumers of energy, thus having a great environmental impact, apart from the energy consumption but because of the significant impact of construction materials to the environment during production, manifesting through its embodied energy, and disposal. The present condition of the existing building stock in EU is deeply unsatisfactory. Most buildings are ‘sub-standard’ in terms of energy efficiency, comfort and health. In Croatia, the largest share of energy consumption in buildings is used for space heating and more than 83 % of buildings consume from 150 to 200 kWh/m2/a of energy for heating. In EU buildings consume around 40 % of energy needs and account for 36 % of EU’s CO2 emissions. Therefore, these countries have decided to implement plans to increase energy efficiency in their national energy strategies and to develop legal framework for the implementation of these plans. Thermal conductivity of the concrete made by using the recycled concrete and recycled brick as aggregates are 36 % and 45 % lower, respectively, in comparison with the thermal conductivities of concrete using aggregates form nature.

Thermal transmittance of the ECO-SANDWICH wall panels is U<0,20 W/m2K. A B C D E F G H

CONSTRUCTION AND DEMOLITION WASTE Construction and demolition waste (CDW) has been identified by the European Commission as a priority stream because of the large amounts that are annually generated and the high potential for reuse and recycling embodied in these materials. Moreover, one of the essential targets of sustainability, as defined in the document Agenda 21 on Sustainable Construction, is the decrease of using non-renewable resources. Proper CDW management would lead to efficient and effective use of natural resources and would as well help mitigate the environmental impacts to the planet. The Waste Framework Directive requires EU Member States to take any necessary measures to achieve a minimum target of 70% (by weight) of CDW by 2020 for preparation for reuse, recycling and other material recovery, including backfilling operations using nonhazardous CDW to substitute other materials. The research in the field of concrete technology made a step forwards in using recycled aggregates, so it can be used as a satisfactory replacement of the aggregates form natural sources. By knowing its physical, mechanical and durability properties of concrete made with recycled aggregates, new application possibilities could be found, thus adding the value to the materials currently being disposed or used for landfill. In order to reflect of the concurrent trends in lifecycle way of thinking, during the production of ECO-SANDWICH wall panels 50 % OF THE TOTAL AGGREGATE QUANTITY NEEDED FOR PRODUCTION OF CONCRETE LAYERS HAS BEEN REPLACED WITH RECYCLED AGGREGATE OBTAINED FROM CDW. When the predicted 75300 m2 of the ECO-SANDWICH panels are installed in Croatia, 7328.20 t of recycled concrete aggregates and 3664.10 t of recycled crushed brick aggregates have been recycled. This represents 16 % of concrete CDW and 23 % of brick CDW in Croatia, and would have a significant impact on the efforts to reduce the environmental impact of construction industry and the need to reduce the disposal of CDW.

ECOSE ® TECHNOLOGY A newly developed mineral wool manufactured using Ecose® Technology, which uses bio based minerals as binder, is used as a thermal insulation material. The ECOSE® based mineral wool provides significant environmental advantages. IT IS MANUFACTURED FROM ABUNDANT RECYCLED (GLASS BOTTLES, PLATE GLASS, INTERNAL WASTE; UP TO 85% OF TOTAL CONTENT OF RESOURCES) AND NATURALLY (SILICA) OCCURRING MATERIALS. According to the BRE Green Guide rating, BREEAM system respectively, ECOSE® MINERAL WOOL USES BIO-BASED MATERIALS FREE FROM FORMALDEHYDE, PHENOL, AND PETROCHEMICALS AND ITS EMBODIED ENERGY IS 70% LOWER THAN FOR CONVENTIONAL MINERAL WOOL. Ecose® based mineral wool in comparison to the sheep’s wool and straw bale used as thermal insulation materials, according to the BRE Green Guide Ratings.

Glass mineral wool with ECOSE® Technology contributes to improved indoor air quality compared to conventional mineral wool. ECOSE® TECHNOLOGY PRODUCTS MEET THE INDUSTRY’S MOST STRINGENT STANDARDS AND GUIDELINES RELATED TO INDOOR AIR QUALITY (M1/RTS Finland, GREENGUARD for Children and School™/ USA, AFSSET/France).


Ecose® based mineral wool is certified as exceptional material, conforming to the Volatile Organic Compounds (VOC) emissions regulations and thresholds, together with regulations regarding the indoor air quality. Eurofins laboratories, Galten Denmark, awarded the Ecose® technology mineral wool with Indoor Air Comfort Gold Certificate. Sampling, testing and evaluation were performed according to ISO 16000-3; ISO 16000-6; ISO 160009; ISO 16000-11; ISO 16017-1; EN 13419 No cancerogenic substances were detectable above their limit values , including 4 carcinogenic, mutagenic and toxic for reproduction (CMR) substances regulated in France Formaldehyde was below the limit value of 10µg/m3 Sum of volatile organic compounds - VOC ( Total volatile organic compounds - TVOC) was below the limit values of 1000 µg/m3 after 3 days and 100 µg/m3 after 28 days Sum of semi-volatile organic compounds (SVOC) after 28 days was below the limit value of 20 µg/m3 Evaluation of individual VOC: R values were below the limit values of 1 for both German NIK (niedrigste interessierende Konzentrationen) and French LCI (Lowest Concentration of Interest) lists after 28 days. Sums of VOC without NIK and of VOC without LCI both were below 50 µg/m3 Quality management system and factory production control program at production site complied with requirements

Knauf Insulation mineral wool with ECOSE® Technology also complies with the voluntary EUCEB (European Certification Board for Mineral Wool Products) certification and Nota Q of Directive 67/548/EEC as amended 97/69/EC and is therefore free from suspicion of carcinogen effects and any associated hazard classification. Glass and stone wool fibres are pre-registered under the REACH (Registration, Evaluation, Authorisation and Restriction of Chemical substances) regulations (EC 1907:2006).
