As a larger consumer of the energy, significant impact of building materials during production (embodied energy) and disposal, buildings have a major impact on the environment.
The present condition of the existing building stock in Croatia and replication market is deeply unsatisfactory. Most buildings are ‘sub-standard’ in terms of energy efficiency, comfort and health. 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 27 buildings consume around 40 % of energy needs and account for 36 % of EU’s CO2 emissions. Therefore, these countries present an ideal market for the application of a durable, energy efficient and sustainable ECO-SANDWICH® wall system.
Thermal transmittance of the concrete with recycled aggregate is 36% lower than the thermal transmittance of the concrete with natural aggregate. Also thermal ransmittance of the concrete with recycled bricks is 45% lower than than the thermal transmittance of the concrete with natural aggregate.
