Performance criteria for dynamic window systems using nanostructured behaviors for energy harvesting and environmental comfort

A Computational Design Framework Supporting Human Interaction with Environmentally-Responsive Building Envelopes

“…Visualizing the EDDS variable combinations in accordance with different latitudes/longitudes, times of day and year, and site orientations is critical for addressing environmental and programmatic demands. • Develo pment o f algo rithms fo r calculating dynamic glazing perfo rmance: The EDDS is capable of dynamically modulating daylight transmission and heat gain while responding to occupant design choices [7]. Dynamically calculating the glazing performance values of various EDDS states will aid in determining control strategies that meet environmental performance goals for daylight and heat gain.…”

“…Building envelope technologies that dynamically respond to internal stimuli, such as lighting, temperature, and people, provide individual control over comfort and privacy and often lead to greater satisfaction with the indoor environmental quality and overall occupant well-being [3,4]. Motivated by studies demonstrating possible undesirable effects that automated environmentally-responsive systems have on occupants' psychological and physiological comfort [3][4][5], designers of dynamic building envelope systems are recognizing the need to embed aesthetic variability and manual user overrides into their criteria for response and also the risks associated with compromising energy performance of the system [6][7][8][9]. The complexity of demands on dynamic building envelope systems that can simultaneously yet distinctively respond to both external and internal stimuli creates a challenging set of performance criteria for designers of state-of-the-art technologies.…”

A Systematic Review of the Most Recent Concepts in Smart Windows Technologies with a Focus on Electrochromics

“…The use of smart glass, which helps to regulate the amount of light (and heat) entering a building, is one of the possible ways to reduce energy consumption in buildings while maintaining an appropriate level of comfort for users. Smart glass greatly influences the building envelope performance in (i) thermal management, (ii) daylight harvesting and regulation, (iii) reduction of glare, (iv) maintenance of views, (v) power capture, and finally (vi) activating the envelope as information display [7]. Some technologies are currently available on the market, although-in light of the many shortcomings of the existing solutions-smart glass is the subject of ongoing "intensive research aimed at improving the technology and its widespread use" [8].…”
