Plug load reduction: The next big hurdle for net zero energy building design
free download
This paper discusses the importance of reducing plug loads as the industry embraces net zero energy buildings. As buildings have become more energy efficient, plug loads as a proportion of the building load have increased significantly. Data is presented to explain this
Concept project of zero energy building
