Special Features

Q-1 Comfortable, Healthy, Safety Indoor Environment
  • Heating and cooling load is reduced through the higher heat insulation spec. conforming to the current national standard, using large heat-insulating wooden sashes etc.
  • Careful considrations are given to natural cross-ventilation and solar-shading
  • Building materials are carefully selected in terms of safetyness, by consulting MSDS to avoid hazard to health such as VOC.
  • Security glass is applied to all the windows except small ones.
Q-2 Sustainability to Service Life
  • Site-specific safer foundation system and form are develped on the basis of the ground survey.
  • Beautiful, robust and self-recoverable timber framework is designed using traditional straight and angle timber joints.
  • Long durability of the timber structure is enhanced by preventing condensation through providing under-floor ventilation, exterior cavity-wall system for venting, and continuous heat-insulated zoning and vaporproof sheets.
Q-3 Regional Contribution for View and Ecology
  • Depth of eaves and the roof angle are determined in harmony with surrounding houses.
  • Exterior finishing materials are selected to be able to enjoy the maturing process of color tone and texture over time.
  • Long-life timbers of locally produced cypress are used for the ground sills and the braces and trusses that support floors.
LR-1 Saving of Energy and Water
  • In addition to diverse passive measures of energy conservation, some active measures are also applied such as a heat-pump hot water supplyer (COP4.55) using CO2 as natural coolant.
  • PV solar panels (1.8kW) are installed on the pergola in the nothern garden.
  • Fluorescent lamps of warm light are used where possible.
  • Extremely long-life lamps are selected for the exterior, Lookout Tower and other places where changing bulbs is difficult.
LR-2 Resources and Materials
  • Heat insulation mateial, recycled from PET bottles, is used in the outer walls.
  • No special measures of waste reduction are applied during the production stage of building elements, however, thorough information and instruction regarding material recycling are given to the contractors prior to the start of work on site.
LR-3 Contribution for Environment of Earth, Region & Town
  • Existing trees are preserved as much as possible, and indigenous trees are to be newly planted where necessary.
  • Seasonally healthy and comfortable micro-climates are created around the house. They include 'Cool Spots' under thepergola in the northern garden, associated with existing trees and pond on-site.

These cases are described based on assessment results obtained using CASBEE.
CASBEE is a method for rating the environmental performance of buildings using Building Environmental Efficiency (BEE) as an indicator, which is based on the results of separate scores obtained for Q-1~Q-3 (Quality) and LR-1~LR-3 (Load Reduction).
