ABOUT US

 

We optimize buildings in an integrated design process with the rest of the design team to achieve supreme energy and environmental performance and optimal IAQ. We use advanced computer tools to optimize the building design to achieve the lowest initial costs and the lowest life time costs for the client.

Our knowledge on energy efficiency and green buildings is the result of 34 years of experiences from Europe and Worldwide, including 10 years in SE Asia.

When Integrated Design Optimization is implemented a LEED Gold building typically costs less than 5% extra, and it is a least 5% more valuable. There are no real extra costs for green buildings, only savings.

MISSION

 

Why do we do what we do?

Our mission is to influence and implement quantifiable positive change to the design, construction or/and operations of any buildings

 
VISION

 

We imagine a world where all buildings in the world are energy efficient, environmentally friendly, low carbon, and healthy living conditions, and green buildings are major contributors to solving the climate crisis and ensuring future sustainability for many generations to come. 


OUR WAYS

We strive to think out of the box. Rooted in a firm understanding of building physics, we formulate and strategize innovative sustainable design solutions.

We use building simulation software to prove our design solutions and influence design optimization decisions in an integrated design process and walk through the implementation process. We measure, analyze and quantify the performance and results of the design solutions.
