Energy Efficient Houses

• Timber frame homes are one of the most amazing
  houses a person can have.
• The concept of passive houses today is to have
  the highest energy standards in the construction,
  reducing energy consumption for heating up to a
  whopping 90. Wide application of this standard
  in the construction of individual or collective
  homes and institutional buildings would have a
  dramatic impact on energy savings.

• Data from the US Energy Information Agency shows
  that in the developed world (Europe and North
  America) buildings are "guilty" for about 48 of
  discharged greenhouse gases per year and about
  76 of the energy produced by plants goes to
  supply buildings (homes, institutions ,
  production facilities). We all know clearly that
  the construction sector (buildings) is one of the
  main pollutants and causes of climate change, so
  here comes the question is How to satisfy our
  energy needs of our construction and protect the
  nature at the same time and save money? In the
  area of ??energy efficiency, passive houses are a
  great option for new and technologically advanced
  construction, both residential and commercial and
  institutional projects.

• Passive house is very well insulated, almost
  hermetically sealed construction which is mainly
  heated by passive solar heating and internal
  heating from people, electrical equipment, etc.,
  where the energy losses are minimized. Any
  additional heating (if required) is provided by
  small sources. With proper shading (eaves, trees)
  and orientation of windows, you will also
  minimize the need for cooling devices. By
  building a fan with energy recovery (ERV) that
  provides continuous and balanced flow of fresh
  air you will have a wonderful temperature in the
  house. The result is a system that not only
  reduces heating costs up to 90, but also
  provides high quality atmosphere inside.

• A passive house is a comprehensive system. The
  word "passive" describes the capacity of the
  system for receiving and retaining energy. Since
  working with natural resources, free solar energy
  is absorbed and distributed efficiently without
  relying on "active" systems that would allow the
  building to reach zero consumption. The main
  feature of passive houses are triple glazed glass
  windows, great isolation, encapsulated
  construction of the building, natural building
  materials, minimal heat conductivity through
  construction and fan with energy recovery.

• In the last 10 years in Europe were built more
  than 15 000 buildings in passive house standard,
  from individual to collective homes, factories,
  schools and office buildings. Many of these
  buildings are under the supervision of EU bodies
  (European Commission) who examine and confirm
  their performance. The European Commission has
  already approved this standard as part of a
  strategy for energy efficiency.

• Technical features
• Encapsulation structure lt0.6 ACH (change of air
  per hour) at 50 Pascal's pressure
• Annual need for heat lt15 kWh / m2 / y (kWh per
  square meter per year)
• Primary energy lt120 kWh / m2 / y
• Additionally, it is recommended to have the
  following measures
• U-value window lt0.8 W / m2 / K
• Ventilation system with energy recovery greater
  than 75 efficiency and low power consumption
• Heat transfer through the structure lt0.01 W / mK
  (thermal conductivity, watt per meter kelvin)
