Energy-efficient homes
Nominal power for heating needs reduced by 18.4% compared with conventional building solutions
Heat loss through façade
Building with hemp ECOblocks reduces heat loss through the façade (walls and thermal bridges) by up to 39.7% compared to a convencional single-wall brick solution with 5 cm of ETICS.
The annual energy consumption of a building with hemp ECOblocks is reduced by 17.3% compared to conventionally constructed buildings, which represents a saving of 0.17 €/kWh.
Heat loss from a building surrounded with ECOblocks is reduced by up to 10.2% compared with heat loss from buildings with double walls and 4 cm of standard insulation.
Case study
The use of hemp ECOblocks in construction of a building guarantees a higher thermal and energy performance compared to a building constructed with convencional brick masonry and high-performance thermal insulation conforming to the regulations of Decree-Law n,º 101-D/2020. No additional thermal insulation is required when building with ECOblocks.
