How to Realize Healthy and Comfortable Buildings with Low Energy needs

Since ancient times, buildings have protected man from wind, rain heat and old. An appropriate building design can help man to enjoy nature and to make use of it for his comfort, thus not needing much energy.

The Buildings are designed to keep comfort with as little energy as possible: high comfort at low energy needs.

The Keller Technology is Based On

• The scientific research of Professor Dr. B Keller in the company in Switzerland (patent No.EP 0177657 A1)
• Practical experience with the planning, the erection and the operation of such buildings in Switzerland, the Netherlands, Finland, Germany, Canada.
• The advanced fundamental research done at the Chair of Building Physics of the Swiss Federal Institute of Technology (ETH) in Zurich.
• The adaptation of this construction technology to the Chinese environment by Dr. Tian Yuan.
  

What are our Principles of Building Technology

It is KT's strategy to build a best construction for any type of climate and user needs based on the following considerations:

• Base the project on the budget
  
• Fully utilize the surrounding natural environment
  
• Selecting materials according to their specific properties and the use
  
• Tune the construction design and the selection of the materials to keep the inner temperature within the comfort range without any cooling or heating for most of the time of a year

• Heating need only
  No cooling, lower the heating power and consumption
  
• Cooling and heating need
  lower the cooling and heating power and consumption
  
• Cooling need only
  No heating, lower the cooling power and consumptio
  

This is attained by:
A high insulation level of walls and roofs
Making use of today’s glazing and coating technology
An adaptable sun shading
An air thight construction of the building envelope
A high noise protection level

This allows a soft technology for heating, cooling and ventilation.
