ENERGY construction system residences meet energy class A. “Energy houses” or “Energy efficient houses” are houses designed and built according to the new Greek Energy Efficiency Regulation of the Buildings (“KENAK”) and are classified into 4 categories, B, B+, A, A+, according to their overall energy efficiency
Residences’ classification is achieved through the KENAK computing process. The classification is the comparison of the overall primal (that is, network-provided) energy consumption that the building will perform during its future use, for heating, cooling, and hot water supply, with the consumption of an ideal similar reference building, which includes specific equipment and insulation capacity, declared B energy class minimum standard. Thus:
class A+ 67% less consumption than B
class A 50% to 67% less consumption than B
class B+ 25% to 50% less consumption than B
class B 0% to 25% less consumption than B
EasyGreen ENERGY houses (depended on design and location*) are classified in energy class A, therefore they display 50% to 67% less energy waste than the energy class B houses (houses also referred as “residences in comply with KENAK”).
ENERGY series are constructed in any desired architectural form.
*Energy classification is related with the specific data of every house: location, dimensions, openings, heating and cooling systems’ installed, neighboring buildings’ position etc, and thus in some cases may be classified in energy class B+.
ENERGY system houses of Easy Green are equipped with :
ENERGY exterior wall system, have high thermal insulation capacity with a coefficient of thermal conductivity equal to U = 0,13 W/m2k.
Synthetic window frames with double glazing, low emissivity film (Low-e), argon gas between panes and heat transfer coefficient Ug 1,0 W / m2k.
Energy technology roof insulation with heat transfer coefficient U = 0,16 W / m2k and a total thickness of 453 mm.
Energy class A heat pump with fan coils for cooling and heating in one system, with energy consumption up to 3 times less than a typical heating system.
ENERGY construction system cost is substantially lower to the cost of energy consuming concrete houses, and does not exceed average building cost for an average other-type prefab residence, which, in most cases, qualifies into a lower energy class and stands lower in housing equipment. Indicative cost for ENERGY housing (for a total house unit area above 80m2) varies at about 800 € / m2*.
*The above cost is valid on building the house from the foundation plate and up, with materials according to the specifications’ guide for ENERGY series, does not include VAT and is clear of long distance extra cost only for the regions of Attica, Viotia and Evia.
* calculated with price of 0,12 €/kWh.
