energy efficient house

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

characteristics

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+.

equipment

ENERGY system houses of Easy Green are equipped with :

construction cost

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.

advantages

  • Overall consumption per final user for heating, cooling and hot water supply for ENERGY series efficient houses stands less than 20kWh/m2, therefore in a 120m2 house we may need less than 2400kWh per year or less than 300€* for heating, cooling and hot water supply annually.

    * calculated with price of  0,12 €/kWh.

  • Thick insulation, absence of thermal bridges and high air tightness, protect energy efficiency houses of the ENERGY series from thermal changes or humidity and endorse the structure with unlimited lifetime and minimum maintenance costs.
  • Stable temperature inside and high thermal comfort ensure a hygiene and convenient living.
