Synergistic House for Healthy Living


Live in clean air with
reduced allergens

Needless to say, the air we breathe on a daily basis has a major impact on our health.

KANEKA Housing Solution reduces the risk of mold growth by ensuring good ventilation, which reduces the risk of condensation.

The system also uses a chemical-free method to prevent termite infestation. The automatic ventilation system will transform outside air that is contaminated with allergens into clean, indoor air.

KANEKA Housing Solution enables all family members to breathe deeply and enjoy your life.

Houses are full of allergens.

Dust, mite excrement and carcasses, dandruff, mold, cigarette smoke,
and pollen from outdoors...these contaminants are known as allergens and house dust.
It is known that inhaling them can prompt an allergic reaction in some people.

Our termite control method doesn’t rely on
chemical treatments, so there’s no need to worry
about“sick house” syndrome.

KANEKA Housing Solution uses the Termimesh Foam SystemTM, a termite control system that doesn’t use chemical treatments. It keeps out termites by applying a gapless layer of stainless steel mesh that is resistant to the insects’ excretions to the outer insulation that covers the foundation and other areas where termites could get into the house.

Save energy with outer insulation and
double ventilation

KANEKA Housing Solution envelops the entire house with thermal insulation, from the foundation to the roof, to ensure a high level of airtightness and lock in warm air.

Thanks to KANEKA Housing Solution, all areas are warm during winter, including stairwells and vaulted ceilings, the living room where family members gather, bedrooms, the kitchen, and bathrooms.

During summer, heat is exhausted through the outer circuit, while the inner circuit serves to keep the house cool.
The system will save energy cost, even for large, open spaces that are usually associated with higher energy expenses.

How does KANEKA Housing Solution
keep homes cool in summer and warm in winter?

Our outer insulation/double ventilation system wraps the frame in three
layers--an exterior material, a thermal insulator, and an interior material--with two ventilation channels (air layers) in between.
During summer, the system exhausts indoor heat and humidity to keep the house cool.
During winter, dampers in the foundation are closed so that indoor heat is retained.

Airtightness, indicated by the so-called C-value,
affects comfort, making it a key consideration
when choosing a home, we believe.

Despite its importance, the C-value receives little attention.
This value, which is also known as the equivalent gap area, is calculated by dividing the total area of gaps in the house by the structure’s floor area. KANEKA Housing Solution home has C-values of 1.0 c㎡/㎡ or less, which means the gaps in a home of about 133㎡ have a total area of about one postcard.
The smaller the total gap area, the less indoor heat can escape in winter, making the house more resistant to condensation.

Attic temperature is cooler than outside air even in midsummer...

During summer, heat from the sun causes the temperature inside the house’s frame (particularly in the attic) to rise above the ambient temperature.
Under such conditions, the thermal insulation covering the frame in KANEKA Housing Solution limits the effect of this heat on indoor spaces.
In addition, by opening the attic and underfloor spaces so that heat and humidity can be exhausted from the house, the entire home can be kept at a more comfortable temperature.
This design also helps limit cooling costs, which can be a concern during summer.

Just ventilating the inside of the walls results in
a difference of 2°C (3.6°F) in midsummer!*

*Contract research: The Kato Laboratory at the University of Tokyo’s Institute of Industrial Science calculated the trend underlying temperature changes based on a verification of the benefits of ventilation in an actual home.
Calculation results do not constitute
a guaranteed level of performance as values vary due to the weather, building conditions, and lifestyle.

Reducing condensation
to help the long life of your home

If you see excessive condensation on windows and walls, it’s a sign that the home wasn’t designed thoughtfully enough.

It’s necessary to consider areas that will be concealed from view once the home is completed during the design stage, for example by including thermal insulation to reduce the risk of condensation and ventilation so that air can move freely.

Protecting the foundation and its anchor bolts
from the risk of condensation

KANEKA Housing Solution thermally insulates the outside of the foundation. This design feature makes the foundation less susceptible to the effects of out-side air, allowing stable temperatures in underfloor spaces.
It also improves the durability of the foundation, which supports the house.
Adding external insulation to the foundation is more effective than insulation on the inside the foundation at keeping the temperature near the anchor bolts that secure the frame to the foundation high, limiting condensation and reducing the risk that the foundation will deteriorate over time.

KANEKA Housing Solution home survived with
little airtightness change even after 16 years
had passed since its completion in this case.

When we investigated how a model house had deteriorated over time in advance of tearing it down to rebuild it, we found neither rot in the structural frame nor signs of internalcondensation.
When we measured the C-value, we found a value of 0.3 c㎡/㎡, compared to a value of 0.1 c㎡/㎡ when the building was completed 16 years earlier.
(Homes with a C-value of 1.0 c㎡/㎡ are generally considered to have a high level of airtightness.)

with the energy used by a cooling system set up to operate intermittently (in individual rooms)
in a home with the same level of insulation performance as KANEKA Housing Solution.
