Case study on how Arby's Restaurant Group's innovative approach to rooftop unit (RTU) management garnered them $287,000 and 2.9 million kWh in annual savings.
It is still early in the collection and analysis of energy performance data, but it is already clear that high-performance commercial buildings—some "almost net-zero buildings"—can be constructed cost effectively, providing productive environments for occupants, reducing operating costs, and enhancing the competitiveness of commercial properties.
This paper describes how net-zero energy buildings will produce, during a typical year, enough renewable energy to offset the energy they consume from the grid.
This conference paper discusses four well-documented definitions of net-zero energy: net-zero site energy, net-zero source energy, net-zero energy costs, and net-zero energy emissions, along with pluses and minuses of each.
This paper introduces a classification system for net-zero energy buildings (ZEB) based on the renewable sources a building uses.
