Learning
Objectives
• Understanding the opportunities and
challenges of implementing retrofits of
advanced lighting and shading systems and
controls in occupied office spaces.
• The different types and appropriate
applications of advanced lighting and shading
systems, including high efficiency lighting,
shades, controls, extended daylight
penetration, tuning, occupancy.
• How metered and measured demonstration
projects can advance wider implementation of
advanced controls, including evaluation of
energy use, occupant satisfaction,
maintenance, and other factors.
• The tools and techniques to advance the
market transfer and widespread adoption of
versatile and energy efficient advanced
lighting, daylighting, and shading retrofit
systems and controls.be-exchange.org

The “Headlines” from
The New York Times Building
2003: Building designed to save energy, satisfy occupants
• Shading systems and lighting control systems were rigorously
developed and evaluated in a full scale test bed
• Owners engaged key systems suppliers via performance specs
2013: Systems (dimming, shading, UFAD) worked well
• Compared to a similar Code-compliant building:
• 56% lighting energy savings
• 24% total energy savings
• 21-25% reduction in summer peak demand
• Economic Paybacks appear very reasonable
• Overall Occupant Satisfaction is high
• All-glass building!! But with “Integrated Building Systems”

12. Future: Significant Impact Comes Only from
Comprehensive Balanced Program
To routinely deliver high performance lighting in low-
energy buildings we must find a balance between:
Technology
Process
Solutions fail without this balance
Markets
Economics
Policy
People
Innovation
Create Mutual Benefits for Lighting Systems
in High Performance Buildings
Win-Win Oppportunties:
• New Technology, Smarter Design offers:
• New Business Opportunities
• Design freedom and flexibility
• Value-added benefits, e.g. better comfort
• New performance benefits: e.g. visibility
• Modest extra costs, large annual savings
• Lower impact on global environment
Manufacturer

Society
Make high performance and energy efficiency a market
advantage, not an extra cost or a risk
Must Deliver Measurable Savings!
