John A. Herbert presented on energy efficiency opportunities in buildings at an HAESCO Energy Seminar. He discussed how buildings account for a large portion of electricity and energy usage. Implementing energy efficient measures like installing variable frequency drives on electric motors can provide attractive returns on investment with paybacks of one year or less. He proposed introducing mandatory building efficiency labels to create transparency and competition, similar to miles per gallon labels for vehicles. Designing energy efficiency into new building projects from the start can lower lifetime energy costs through measures such as optimizing piping layouts and installing smarter metering. Energy audits can also identify savings opportunities that generate net savings for businesses and the economy.
