Saving energy in water heating systems

摘要

In today's era of U.S. Green Building Council LEED certification, planet preservation, and "green" markets and mandates, the overall trend has been toward saving energy within buildings wherever possible and creating more sustainable construction methods and equipment. Many of these new technologies and designs have been centered around visible building systems (e.g., high-performance glazing or wall/roof structures, and low-VOC carpeting, paints, and millwork) or highly documented energy users (e.g., variable frequency drives on central plant pumps, chillers, energy-efficient LED or CFL lighting, and condensing type boiler systems with low supply water temperatures and large temperature differentials).
