Industrial Revolution spawned the development of modern technologies and industries, but a firm understanding of efficiency and its importance was not immediately understood. Measures to improve efficiency and reduce the environmental consequences of energy production and use were not implemented until well into the twentieth century, and result in reduced energy consumption and environmental impacts, easier compliance with regulations, and greater profitability. Nearly all industrial and commercial ventures today involve in-depth and sophisticated analyses that ensure that systems operate at peak efficiency with minimal environmental and carbon impacts.

One of the more effective means of increasing energy efficiency in commercial buildings is to “seal the envelope,” that is to employ construction techniques that reduce air exchanges between inside and out through walls, windows, doors, and other openings. Sealing the envelope saves money, reduces noise from exterior sources, increases humidity control, and ensures lower interior pollen levels.

Other energy efficiency tips include to:

• insulate open tanks, flanges, valves, and openings;
• regularly service HVAC control systems;
• installing a building automation system (BAS) or energy management system (EMS) or service existing systems; and
• employ morning pre-cooling in summer and pre-heating in winter.
