A Perspective on the Future
“No sensible decision can be made any longer without
taking into account not only the world as it is but the
world as it will be.”

Learning from the Past
In the past, buildings in warm climates had operable windows with awnings for shade, high ceilings and portable fans.

Learning from the Past
The U.S. National Academy of Engineering selected air-conditioning and refrigeration as one of the “Greatest Engineering Achievements of the 20th Century.”
Since 1940 eight of the 10 fastest growing cities in the U.S. are in the southern part of the country.
Today, in excess of 55% of the entire U.S. housing stock has central air-conditioning and 75% of all newly constructed homes have central air-conditioning.

The HVAC Market
33,297 CFC chillers still remain in use in the US.
Replacement chillers are at least 40% more efficient than those installed 40 years ago.
CO2 production has been reduced by 4 million tons/year as a result of chiller replacement.

Influences on HVAC&R Applications
1. Energy
The U.S. residential and commercial sectors account for 40% of the total energy consumed in the country.
41% of all electricity consumed in commercial buildings is for comfort cooling, ventilation and refrigeration.
Consumers are demanding sustainable building design, construction and operation are key.

Influences on HVAC&R Applications2. Environment
“If every centrifugal chiller had an efficacy of 0.48 kW/Ton vs. 0.56, annual plant emissions would be reduced by• Nearly 17 billion pounds of C02
• Over 64 billion grams of SO2
• Over 27 billion grams of Nox
Which is equivalent to:• Removing over 2 X 106 cars from the road• Planting nearly 500 X 106 trees each year.”

3. Human Factors
Employee cost per unit area of an office building in the U.S. is 100 times that of the operating cost of the building.
Jeopardizing employee performance because of poor control of the indoor environment could be a major cost to employer.

4. Political
Public policy affecting building design, construction and operation must be based on solid technical principles, not politically based restrictions.
System design and performance standards must be uniform throughout the globe and be based on technology rather than market protection.

6. Communication
The internet gives us a “flat” world. It allows us to
Share educational programs,
Relay and discuss research results* and
Create global design teams independent of location.
*Information available on the Web may not have undergone the scrutiny of peer review.
