Project Description
First ECO-SANDWICH® House is a unique example of a holistic and innovative approach to sustainable architecture. The house is located in the Green Quarter of City of Koprivnica in Croatia, within the program of social housing. ECO-SANDWICH® wall system was developed as a result of cooperation between Croatian scientific institutions and industry. It is a ventilated prefabricated wall panel that utilizes recycled construction and demolition waste (CDW) and mineral wool.

Description of the project
Summary
First ECO-SANDWICH® House is a unique example of a holistic and innovative approach to sustainable architecture. Realization of the house was the final phase of ECO-SANDWICH® project funded by the European Commission within the framework of CIP-EIP-Eco-Innovation 2011 Programe.
ECO-SANDWICH® wall system was developed as a result of cooperation between Croatian scientific institutions (Faculty of Civil Engineering and Faculty of Architecture, University of Zagreb) and industry. It is a ventilated prefabricated wall panel that utilizes recycled construction and demolition waste (CDW) and mineral wool produced using innovative and sustainable Ecose® technology. ECO-SANDWICH® won a gold medal at the International Exhibition of Inventions INNOVA 2014 in Brussels!
Investor was Agency for Socially Supported Housing Construction of Koprivnica, a non-profit organization that plans and builds dwellings in City of Koprivnica’s “Green Quarter”, where three bigger passive house standard multi-family houses with around 28 apartments have already been built.
First ECO-SANDWICH® House is the first completed multi-family house in the “Green Quarter”, within the program of social housing. First ECO-SANDWICH® House is also a brand new residential type within the Social Housing Programe in Croatia. It is a multi-family house with three different apartments, each on every floor.
Key objectives for sustainability
ECO‐SANDWICH® tackles four major environmental problems. It reduces greenhouse gas emission by energy efficiency of buildings, it reduces energy consumption in building sector, it increases resource efficiency through the use of construction and demolition waste (50% of total aggregates is obtained from recycled aggregate) and it minimizes the use of regulated chemicals like phenol and formaldehyde from the insulation material production process. The first ECO-SANDWICH® House was designed as a passive house (A+) but also as a passive solar house which is closed on the north to limit energy loss and open on the south to utilize solar radiation.
Key objectives for aesthetics and quality
First ECO-SANDWICH® House is the World`s first application of ECO-SANDWICH® wall system. It is a ventilated prefabricated wall panel that utilizes recycled construction and demolition waste (CDW). The project itself and realization of the house explored the possibilities of applying the ECO-SANDWICH® system. House needed to be designed considering all the specifics of construction with prefabricated panels, such as their maximum dimensions and the way of assembly. The easiest way would have been to design a simple, compact house with similar layouts, details and openings on every floor, and with the biggest amount of identical prefabricated wall-panels. However, this method would not reveal all the possible difficulties and problems, and would not offer any checked solutions for next implementations of the system. Therefore, the building was designed as the most complex, with cantilevers, corner windows, loggia, balconies, etc., to solve as many details as possible and to create a catalogue of solutions for future applications. Of course, all the details meet the Passive house standard criteria, such as avoiding thermal bridges, airtightness, etc.
Key objectives for inclusion
ECO-SANDWICH® wall system was developed as a result of cooperation between Croatian scientific institutions (Faculty of Civil Engineering and Faculty of Architecture, University of Zagreb) and industry. The project was one of the first examples of cooperation between public scientific institutions and private sector (industry) gaining new qualities from the interdisciplinary approach that unite science, professional knowledge and practical experience.
Results in relation to category
The First ECO-SANDWICH® House is the World`s first application of ECO-SANDWICH® wall system. Techniques and processes for construction and design using a new innovative ventilated prefabricated wall panel that utilizes recycled construction and demolition waste (CDW) were researched in the design phase and finally tested after realization of a house within the Social housing program in Croatia.
How Citizens benefit
The first ECO-SANDWICH® House is a brand new innovative residential type within the Social housing program in Croatia. It is a multi-family house with three different apartments, each having its own garden equipped with electrical and water supply.
