Architects Say Let in the Light

New survey confirms architects want to maximize natural daylight in building designs but are frustrated with traditional sun control methods like blinds and shades  Natural light has clear benefits for building occupants, but traditional methods of controlling solar heat gain and glare are limiting the potential to maximize daylighting designs.

That is the conclusion of a recent survey of architects conducted by Hanley Wood, a leading media and information company in the construction industry. 

Commissioned by SageGlass®, the leader in dynamic glass, the survey of 300 architects found 97 percent agree that people perform their jobs or functions better in buildings when exposed to natural light. This finding is consistent with the ongoing trend towards optimizing natural daylight while reduce building energy use.

But while the surveyed architects understand the benefits of designs that maximize natural daylight, 95 percent said solar control is still a significant issue in building design. Traditional methods of controlling the sun have always been a source of frustration to architects who design with glass, and only eight percent of the architects surveyed strongly agreed they are satisfied with their options for managing solar control today.

“Everyone enjoys a sunny day – until it affects us with glare in our eyes or too much heat in our space,” said Dr. Alan McLenaghan, CEO of SAGE Electrochromics, Inc., the manufacturer of SageGlass. “The research we have done affirms that architects are in-tune with this issue and are actively looking for innovative ways to better manage the sun for the comfort of building occupants.”

Controls such as mechanized shades, blinds or exterior louvers may block the sun but also limit exposure to daylight and the view to the outdoors – the very reasons why windows are designed into building facades. This fundamental issue is creating an opportunity for new technologies such as dynamic glass.

SageGlass is electrochromic dynamic glass. It electronically tints and clears on demand to block up to  99 percent of visible light (i.e. one percent visible light transmission) – the level required for excellent heat gain and glare control – as well as harmful ultraviolet rays that can cause fading of rugs and furnishings.

“This research demonstrates why dynamic glass is generating increased interest in the glazing and construction materials market,” said Derek Malmquist, vice president of marketing at SAGE. “Dynamic glass is a triple-benefit solution. You can block glare and heat from the sun, save energy, and let in just the right amount of light so building occupants are happy and productive without having to sacrifice natural light or a connection to the outdoors.”

The survey also identified a couple of key misperceptions about dynamic glass. Category confusion was revealed in 22 percent of respondents indicating they believed that dynamic glass was also “privacy glass”. Unlike privacy glass, SageGlass, even in full tint mode, is designed to intentionally provide a view to the outdoors.

Cost was also still a concern for those surveyed, but 20 percent of the architects questioned indicated they believe dynamic glass is indeed affordable, while 50 percent were undecided or “neutral” on the question. This illustrates there is still a need for education. In fact, solutions such as SageGlass are very competitive with traditional methods of solar control. Traditional methods require architects to budget for not only low-e windows, but also shades or blinds (plus installation and maintenance), exterior sunshades (plus transport and installation), larger HVAC systems, more lighting, increased energy usage, and peak demand electricity charges.

“While our potential customers invariably see SageGlass as an ’expensive premium glass product’, they are usually pleasantly surprised by the affordability of SageGlass when they remove the costs required for additional sun control devices and the maintenance associated with them,” said McLenaghan.
