What is a High Performance Building?
● “….Green building is also known as a sustainable or high performance building”
- US EPA
● “…a building that integrates and optimizes all major high-performance building
attributes, including energy efficiency, durability, life-cycle performance, and
occupant productivity
-Energy Policy Act of 2005
● “One that uses less water, optimizes energy efficiency, conserves natural
resources, generates less waste, and provides healthier spaces for occupants”
-Indian Green Building Council
● “….. environmentally sustainable building, designed, constructed and operated
to minimize the total environmental impacts.”
-Build Green
● “The building is a citizen of the city and has an obligation to society”
-Xiaowei Xu, PhD., Chief Engineer, Shenzhen Institute of Building Research
?
Does a high performance building have to be designed as
green or is it about optimizing performance?

Optimizing Energy Use
Persistent Energy Savings
Active EE
Passive EE
30% savings are available today…
● Efficient devices and efficient installation (10 to 15 %)
Low consumption devices, insulated building…
● Optimized usage of installation and devices (5 to 15%)
Turn off devices when not needed, regulate motors or heating
at the optimized level…
● Permanent monitoring and improvement program (2 to 8%)
Rigorous maintenance program, measure
and react in case of deviation

But…….… The long term challenge is
sustained energy savings
● One step is not enough, savings are lost due to
● Behavior & Commitment
● Lack of visibility
● Lack of Automation

Challenges
Keys for long term success
High Performance Building Inhibitors
● Market Inhibitors
● Low awareness and inadequate skills
● Limited incentives for designers and builders
● Comparative usage understanding
● Technology Inhibitors
● Systems level solutions/integration
● Measurement & verification
● Financing Inhibitors
● Incentive misalignment
● Limited or inadequate financing
● Regulation
● Inconsistent implementation of compliance with policies and codes
● Inconsistent & immature policies
● Inconsistent utility engagement across states

Energy is invisible.
We need to make it visible!
Benchmarking shows opportunity exists
……in high tech facilities energy
intensity varies significantly
Integrated connectivity gives insight
…. In Data Centers Energy Dashboards
allows optimize management
Schneider Electric
15
Labeling is Still confusing
● Need to be clear on different
labels and their proposes
● operational versus asset rating
● Technical versus statistical
● Need consistency between
competing systems
● Many competing labeling
systems in market today
● Many evolving
