The current state of global warming focuses on six “suspects”: HFCs (which the U.S. hvacr industry has embraced as long-term alternatives to CFCs and HCFCs), carbon dioxide, methane, nitrous oxide, perfluorocarbons, and sulfur hexafluoride.

“We don’t know if the six suspects cause global warming,” said Wolf. “But they are released in great quantities.”

The key, Wolf said, is making sure the six suspects continue to be lumped together, so should there be enforcement of a reduction in global warming gases, it can be done in a more balanced way, including the buying and selling of credits.

That message is clouded somewhat by pressure from some European sectors to isolate HFCs and force their total phaseout overseas.

Also, carbon dioxide turned out to be a high-profile possible refrigerant during the Purdue proceedings, from those who want to capture it from non-hvacr sources for use in air conditioning and refrigeration systems.

But Wolf’s main message for the industry was, “Start thinking ‘green’ holistically.”

Value vs. first cost

“The idea is, ‘design them right, install them right, operate them right.’” But, he added, that is sometimes not the case. “Building equipment is not often run the way it was designed.”

He encouraged the involvement of the audience of researchers and scientists.

Noting the depth of the research papers presented throughout the week, Wolf said, “You are the visionaries of the future. Ask yourself, ‘Where will the quality of life be without me? Without my colleagues? Without all of us?’”
