"Effective use of daylight is essential in achieving a sustainable building design. The size of a glazed window is proportional to the level of daylight and depends on the proper integration of both window area and glass properties. Improperly designed windows could not only lead to poor illumination in building interiors, but may also cause fatigue, depression, and inefficient energy usage."

The study analyzed the variation of annual heating energy demand, annual cooling energy demand, and the annual total energy consumption in different conditions, including different orientations, patterns of utilization of air conditioning system, window-wall ratio, and types of windows. The results show that the total energy consumption increased when the window-wall ratio is also increased.
Commercial mortgages currently do not fully account for energy factors in underwriting, valuation and asset management, particularly as it relates to the impact of energy costs on net operating income. As a consequence, energy efficiency is not properly valued and energy risks are not properly assessed and mitigated. Commercial mortgages are a large lever and could be a significant channel for scaling energy efficiency investments.
"Vast areas of exterior glazing have a greater impact on energy consumption than any other decision in the design of residential high-rises."
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.
