Passive Constructions – Ecological Constructions

Passive constructions or “ passive houses ” are constructions with almost zero energy consumption. The constructions of the smartpassive series provide great thermal comfort throughout the year and ensure a healthy living without the presence of moisture with the advantage of low energy consumption. The smarpassive range is not limited to homes but also to multipurpose spaces, office spaces, schools, etc.

WHAT CHARACTERIZES A PASSIVE HOUSE

To be a “zero passive” house of almost zero energy, it must comply with the following conditions.

  • The building must be designed in such a way that the annual energy consumption does not exceed 15 KWh / m2 per year for heating and 15 KWh / m2 for cooling per year or be designed with a maximum heat load of 10W / m2. < / li>
  • The total primary energy consumption should not exceed 120KWh / m2 per year.
  • The building must not lose more than 0.6 times the total volume of air circulating per hour.

The criteria followed by a passive house far exceed the criteria established by the competent Greek authority for how energy-intensive and in which energy class the houses are classified. Finally, the reduction of energy consumption of a passive house can reach up to 10% more than the construction of energy classes A +.

Equipment

The series smartpassive following the international standards for the construction of passive houses equips them with the following.

ADVANTAGES:

  • Higher energy savings for cooling-heating hot water compared to A + energy class constructions
  • Eco-friendly
  • Caring for owners from future electricity bill increases
  • Increased comfort due to uniform indoor temperatures
  • Reduction of total property costs due to improved energy efficiency
  • Reduce monthly maintenance costs
  • Minimizes the cost of building a passive house from the beginning in relation to subsequent processing
  • Post-political value higher, in relation to a common construction, than the increase of electricity tariffs
  • Future regulations and laws on carbon dioxide may force the future conversion of a typical building into a liability one.

DISADVANTAGES:

  • Few companies specializing in the construction of low energy buildings
