Building Envelope: 5.81 Quads
The commercial building envelope is the primary
determinant of the amount of energy required to heat, cool,
and ventilate a building
![Page 5: Improving Building Performance with Envelope Technologies · 2018-09-07 · Improving Building Performance with Envelope Technologies Moderator Melissa Voss Lapsa, Oak Ridge National](https://reader034.vdocuments.us/reader034/viewer/2022042803/5f45f2a990c7cc046c12c4f0/html5/thumbnails/5.jpg)
Barriers Identified for Envelope Technologies
▪ Cost: uncertainties, high first costs, ROI hurdles
▪ Supply issues: product fragility, availability, volume
▪ Installation issues: workforce training, complex systems, quality control
▪ Decision culture: resistance to new products, risk averse, code minimum culture
▪ Information gap: real world case studies, data on long-term performance, communicating effectively

AERC is an independent, public interest organization whose
mission is to provide consumers with credible, relevant, and
comparable information about window attachments and their
performance.
AERC members include:
• Public Interest Groups• National Labs• Commercial Labs• Product Manufacturers• Component Manufacturers• Utilities
![Page 54: Improving Building Performance with Envelope Technologies · 2018-09-07 · Improving Building Performance with Envelope Technologies Moderator Melissa Voss Lapsa, Oak Ridge National](https://reader034.vdocuments.us/reader034/viewer/2022042803/5f45f2a990c7cc046c12c4f0/html5/thumbnails/54.jpg)
• Window attachments can save energy
– Many consumers are unaware of their energy-saving capability
• Consumers have no way to compare the energy performance of attachments
• Energy Efficiency program managers also benefit from ratings and energy performance information
Why AERC?
