Could we achieve significant energy savings without modifying the physical structure of commercial buildings?
John writes from New Zealand: “Do you think that a significant amount of energy could be saved in commercial buildings by having more sophisticated HVAC control systems? In other words, could significant improvements be made without modifying the physical structure of buildings?” Answer: That’s a good question. I hope the answer is “Yes” and that it happens soon. Unfortunately, I don’t have any expertise when it comes to HVAC control systems. My energy-saving knowledge all comes from doing insulation commercials. I checked with my friends at Owens Corning and they suggest contacting one or more of the companies that make HVAC control systems. You may be able to find them through their trade associations like ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers), ARI (Air Conditioning and Refrigeration Institute) and CSIA (Control System Integrators Association). There may be similar organizations in New Zealand.
