Application of large-area chromogenics to architectural glazings
- Lawrence Berkeley Lab., CA (United States). Applied Science Div.
Chromogenic coatings are an important emerging technology for the window and building industry. They enhance building performance by improving the energy performance of buildings as well as by addressing all of the related energy/productivity issues that will influence future building design and operation. Smart window technology offers the potential to capture the large savings that can theoretically be obtained by existing technology but will otherwise never be achieved. Benefits include energy savings, electric load shaping, and peak demand reductions, as well as downsizing of HVAC systems. These can be achieved while also providing improved levels of thermal and visual comfort, privacy, view, and other benefits associated with window use. The energy savings potential for switchable glazings has been one of the major forces motivating R and D on the subject. These same forces were critical to the initial market success of low-E glazings. However, it would be a serious mistake to believe that energy cost paybacks alone will drive market development. There are numerous market-context issues that influence the cost, performance, and acceptance of a chromogenic window. Several of these issues (benefits, obstacles, and uncertainties) are summarized. Within this broad perspective the authors are confident that smart glazings will be successfully developed and marketed for architectural applications. Since there are many different building applications and needs, several different smart glazing technologies may all find market niches. In the near term, the versatility of active response chromogenics (probably electrochromics) suggest that they are clearly the switchable glazing type most likely to find widespread applicability in buildings. While there are many difficult technical challenges to be solved before electrochromic glazings become commercially available, there are no obvious insurmountable technical or production problems at this time.
