Present Day
Coal is used to produce about 50% of the electricity in the US and 83% in China. Its use is growing in both countries.
Increase in Chinese power demand adds (2) coal fired power plants per month to the grid.

Present Day
Global climate change is accelerating as greenhouse gas concentration rises faster than expected. CO2 concentration will soon damage ecosystems. .350 is an international movement to reduce greenhouse
gases to 350 ppm .

The Opportunity in Modern Lighting
Lighting is a prime opportunity to mitigate energy use and greenhouse gas production
70% of lighting energy use is by day
50% of lighting energy use is by older, inefficient technologies
Lighting is about 10% of the problem but it can be 20% of the solution!!!!

What is “Zero Net”?
Buildings that give and take energy from the grid, but in the end, have no “net” use.
Required in California by law for all new residences by 2020 and for all new buildings by 2030.

Zero Net Energy
Total non-renewable and off-site renewable sources are considered “Debits”
Total on-site renewable sources are considered “Credits”
End of year: a building is “zero net” if there are more Credits than Debits
Lighting and Daylighting Your Way to Zero Net Energy
James R Benya, PE, FIES, FIALD, LC (US)
Zero Net Electric Time of Use (TOU)
Building energy demand profile does not match non-depletable source profile
Excess thermal energy can be stored but excess electric energy is better off returned to the grid as a “bank”
Bank “account” is depleted periodically
Peak users pay a premium
Peak generators are rewarded

Guiding Principles of Zero Net
1. Negawatts cost less than megawatts. Conservation first!
2. Use passive measures as much as possible. Avoid complex systems except as a last choice.
3. Start with the simple, low cost high payback measures

DAYLIGHTINGThe Next Great Frontier of Design
It is the Key to Zero Net
Lighting and Daylighting Your Way to Zero Net Energy
James R Benya, PE, FIES, FIALD, LC (US)
Daylighting’s Challenges
• Four generations of architects and engineers lost to cheap energy• Limited number of qualified architects, consultants and educators
• No established methodology or dominant theory
• Eighty years of bad habits
• Lighting designers must learn to design daylighting
Lighting and Daylighting Your Way to Zero Net Energy
James R Benya, PE, FIES, FIALD, LC (US)
Architecture’s Challenge: Architectural Fashion conflicts with Building Science
•Glass too transmittive – workers moved 10’ back from windows
•Relies too much on low-e for solar gain control
•Passive shading only works on one of four facades
•Curtain wall poorly insulated
Lighting and Daylighting Your Way to Zero Net Energy
James R Benya, PE, FIES, FIALD, LC (US)
Orientation
•This photo faces north!•20-30X too much daylight•Poor insulation•Too much glare on sunny days•Electric lights all on•Glare control material installed by building occupants also to help control heat gain
Architecture’s Challenge: 70 years of air conditioning have taught us a lot of bad habits
Lighting and Daylighting Your Way to Zero Net Energy
James R Benya, PE, FIES, FIALD, LC (US)
Lighting Controls
Engineer’s Challenge: Lighting controls are “too expensive” and lights are left on by day.
“Value” engineering:
Spend $2Million in energy to save $1Million in control system costs
Lighting and Daylighting Your Way to Zero Net Energy
James R Benya, PE, FIES, FIALD, LC (US)
Waste
More than ½ of the electric light energy goes straight up into the sky
Lighting Designer’s Challenge: controlling ourselves from inefficient designs

Daylighting’s Benefits
Daylighting can save:
• Up to 100% of lighting demand
• The cooling associated with lighting demand
• Excessive cooling due to sub-optimal daylighting
• Cooling energy coincident with other peaks
Daylighting Provides
• Healthier interior environments
• Higher productivity
• Better interior spaces
Lighting and Daylighting Your Way to Zero Net Energy
James R Benya, PE, FIES, FIALD, LC (US)
Steps to Better Daylighting
Use passive measures first• Climate tuned orientation and shading• Cooling season solar gain control
• Passive exterior components (natural and man made)• High performance glazing
• As much insulation as possible• Skylights• Curtain walls
• Multiple roofs and skins for problem orientations• Simple skylights
