Passive constructions – Smart Passive

Passive constructions of our Smart Passive series provide great thermal comfort throughout the year for healthy living without humidity.

Passive constructions, or passive houses, are constructions with nearly zero energy consumption that utilize passive and active heating-cooling systems, minimal energy loss building techniques, energy management systems, etc. Houses of our Smart Passive series provide great thermal comfort throughout the year, ensure healthy living without humidity and have low energy consumption. In fact, ecological constructions of the Smart Passive series are not limited only to residences, but also to multi-purpose spaces, offices, schools, and any type of building.

What is a passive construction or passive house?

A passive construction or passive house is defined as a building where indoor thermal comfort (ISO 7730) is ensured exclusively by preheating or precooling the quantity of fresh air which is required (DIN 1946) for the optimal indoor environment, without the use of additional recirculation of air.

In order for a nearly zero-energy house to be considered “passive” it must meet 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 per year for cooling or with a maximum heat load of 10W/m.
  • The total primary energy consumption of electricity must not exceed 120 KWh/m² per year.
  • The building’s airtightness demonstrates air change of less than 0.6 times its total volume per hour.

Basic passive house criteria

The basic criteria of a passive building are:

  • Insulation (waterproofing & thermal insulation)
  • Ventilation with energy recovery
  • Openings – windows
  • Space airtightness
  • Avoidance of thermal bridges

The energy consumption of a passive house can be up to 10% less than an energy class A+ construction.

What are the key elements of Smart Passive constructions?

Our Smart Passive series follows all international standards for the construction of passive houses. They are built and equipped in such a way, so as to offer the desired energy efficiency.

In more detail, our Smart Passive constructions demonstrate the following characteristics:

  • Metal Frame: Coated and double insulated with extruded polystyrene 10cm thick and λ=0.036w/Mk, expanded polystyrene coating 5-6cm thick and λ=0.036w/Mk. A total of 15-16cm of insulation to prevent and avoid thermal bridges.
  • Masonry: Dry construction with the application of a certified external thermal facade system.
  • PVC doors and windows: triple-glazed PVC doors/windows with argon gas Uw=0.79 W/m2K and Ug=0.6 W/m2K.
  • Heat Pump: Cooling-heating energy class A.
  • Solar Water Heater: Solar hot water heater.
  • Insulation: Roof insulation with expanded polystyrene, bituminous membrane, cement mortar in slope, waterproofing.
  • Ventilation Systems: Ventilation system with heat recovery.
  • Photovoltaic System: Photovoltaic system for complete energy independence.

Passive Constructions - Cost

The cost of our Smart Passive construction series can be estimated after we are presented with the full needs of our client. Each building is different, with its own peculiarities, built according to the owner’s preferences. No matter the case, our basic principle at Smart Building company is to provide excellent and, above all, affordable construction solutions.

Thus, in all passive houses we build, we make sure to offer the best prices in the market. Utilizing the most suitable construction methods, excellent quality materials, and following the latest insulation practices as well as various innovative techniques, we ensure the most ideal result that fully covers your needs.

Advantages of Smart Passive buildings

Passive constructions offer a number of advantages that will help you reduce your energy consumption significantly. In more detail, passive buildings offer:

  • Higher energy savings of cooling or heating water, compared to constructions of energy class A+
  • Care for the environment
  • Care for owners from future increases in electricity costs.
  • Increased comfort in everyday living, due to consistent indoor thermal environment.
  • Lower property ownership costs due to improved energy efficiency.
  • Reduction of monthly maintenance costs.
  • Building a passive house from the beginning costs less than adding energy efficiency improvements later on.
  • Higher market value than conventional constructions, due to the continuous rise of electricity costs.
  • Future regulations and laws on carbon dioxide emissions may require a future retrofitting of a conventional building into a passive one.

Disadvantages of passive building construction

Our Smart Passive houses offer enormous benefits to homeowners. The only so-called disadvantage of this particular construction method is the fact that only a few companies specialize in the construction of low-energy buildings and so, there are just a few professionals that can deliver the desired results.

Smart Building is a company that offers guaranteed results in passive house constructions and, on top of that, at the most affordable cost in the market. For more information, just contact us.
