Wood Trim Energy-Efficient Homes

Energy-efficient homes are environment-friendly as well as budget-friendly.
They drastically decrease residential heat loss, namely energy consumption due to air conditioning.
They also actively cope with the recycling of rainwater and the like in urban areas.

In summer the exterior heat is prevented from entering and in winter the interior heat is prevented from escaping.
The homes' reduction of the consumption of fossil fuels such as oil and gas will help control carbon dioxide emissions and as a result will help the prevention of global warming.
They actively use natural energies such as sunlight, solar heat, wind power and rainwater.
Example: Passive Solar System, OM Solar System
(In Mt. Yatsugatake of Nagano, which has nighttime temperatures of -20 degrees celsius, the daytime roof surface becomes 90 degrees celsius which can be utilized by the floor heating and hot water supply.)
Example: Rainwater used for toilet drainage and roof spraying

Floors and Floor Heating:
Floor heating is recommended but optional.
The floors are heated economically with warm water (or antifreeze kept at the temperature of a bath) under the floor.
The under-floor plumbing uses jointless highly durable polyethylene pipes.
The flooring generally uses woods like cherry with a thickness of 15-18mm (stone and tiles are also suitable for floor heating).
Two coats of natural paints are used on the timber flooring at the building site.

Walls and Insulation:
The general method of construction does not use glass wool, but uses a next generation insulation called "Perfect Barrier."
Perfect Barrier
  • is stronger and in the same price range as high-performance glass wools.

  • is highly insulative, highly sound absorbent, highly permeable and highly fireproof with flame retardant ability.

  • is an ECO mark product which is made from recycled PET bottles and can be used safely.

  • is a trump card against sick houses and is safe not only during use but also during construction.

  • For exterior insulation, phenolic foam is used.

    Windows and Double Glazing:
    Double-paned glass (wooden framed double-glazing) is used.
  • Double-glazing is highly effective in the prevention of condensation and as insulation.

  • Of course ready-made windows are available. However, a variety of custom made windows such as extra large windows etc can also be ordered.
    We can also construct window frames.

    Water and Rainwater Recycling:
    Atelier Vista is considering a system that collects and uses rainwater.
    We are researching this in accordance with housing and regional conditions.
    We can use rainwater for toilet drainage and roof spraying.
    The method and construction shown in the photos are only for reference. We would like to develop this further in the future.
