On the potential for dynamic glass in the near future…  
he potential for dynamic glazing has fostered interesting discussions in our  
office. The practice of Cambridge Seven Associates is very broad, so we  
tend to apply solutions from one practice area to another. Having deployed  
dynamic glass to improve visual and thermal comfort for the envelope at the Museum  
of Science in Boston, we also see innovative applications in our exhibit design work  
within all museums. We might finely tune the appearance of casework or whole rooms  
with variable opacity, perhaps even color. In our academic work, flexibility and adaptabili-  
ty are essential. We’re imagining possible advances in not just visual flexibility, but project-  
able, writable and ultimately more interactive and user-responsive surfaces.

lass curtainwall is becoming the standard façade material.  
Concurrently, we have increasing code-based and ‘green build-  
ing’ emphasis on user well-being. The issues involved are solar  
control and visible light. While ASHRAE energy levels are required to be  
met, there is a new elective program for certification of a building’s connec-  
tion to health, with light as major criteria. Two other developing concepts  
that come to mind for exploring the benefits of dynamic glass are: new research  
into natural Circadian rhythms for health focuses on light control; and resilient  
building design to modulate the exposure to increasing heat wave frequency. The  
dynamic glass industry has focused on solar control for energy quite well and  
could investigate its use in heat wave resiliency. On a new front, I could see  
a collaboration with dynamic glass technology and the various groups  
studying light and wellness. To provide dynamic control of light, glass  
selection could be made that offers a higher level of visible light trans-  
mission, thus allowing for purer, natural light waves during the times  
of day where sun control is not necessary.

lectrochromic glazing systems should continue growing in popularity over the next five years  
because of their contributions to building energy efficiency and operating cost reduction,  
and for their potential for an expanded role in sophisticated building automation systems  
BAS). When dark, electrochromic glazing reduces passage of radiated heat from the sun’s rays. This  
lowers overall HVAC cooling loads. When clear, it allows natural light to enter, reducing electrical  
lighting power and heat loads. In both the light and dark state, electrochromic glazing increases  
energy efficiency and reduces building operating costs. Electrochromic glazing can become an  
integral part of complex BAS. Lighting controllers have become central to BAS, controlling  
HVAC, electrical power and continuously dimming through daylight sensors. The control  
module for electrochromic systems can integrate to create a seamless interplay of continu-  
ous data-based adjustments for building performance optimization.
