Lighting for the LearningEnvironment
Acuity Brands AIA #AB5101 AIA/LU/HSW
June 21-24, 2015Callaway Gardens, Georgia
Best in Class Lighting Solutions: At Acuity Brands, we deliver high-quality, energy-efficient, integrated lighting systems that improve the education experience and reduce operational costs. From the classroom to the gymnasium, from the parking lot to the laboratory, from pre-schools to grad schools, we help institutions achieve enhanced learning environments, increase energy savings, reduce operational costs and improve sustainability.

The Opportunity
Best in Class Lighting Solutions
Lighting represents 2 to 4% of school construction costs, but look at its other impact…
• Economics: After teacher salaries, utilities are the largest operating expense for school districts. And lighting is the largest consumer of electricity on campus.
• Student outcomes: Studies have shown that good lighting can improve the students’ mood, behavior and concentration.
The Opportunity
The Opportunity
$14 BillionTotal spending on energy by the nation’s educational institutions.
• That’s more than we spend on computers and textbooks combined.
• As much as 30 percent is used inefficiently or unnecessarily.
• Lighting is the largest consumer of campus electricity.
• Every dollar wasted on energy = less funding for education.
Note: Energy improvements could save 25%

The Bottom Line:
To use less energy and create a better building, we have to adopt new methods of lighting and lighting management that integrate electric lighting, natural daylighting and controls. (Contact Tim Hogan to get have a cheat sheet with key data.)
IECC• What is IECC ?
A code-intended energy standard that is updated every three years
• Who oversees it ?The ICC (International Code Council)
• Why is this topic important ?The IECC is mandatory in some jurisdictions
Codes and Standards
ASHRAE 90.1
• What is it?An energy standard that becomes code when adopted by some jurisdiction
• Who oversees 90.1 ?ANSI/ASHRAE/IES
ANSI - American National Standards Institute ASHRAE – American Society of Heating, Refrigeration and Air Conditioning EngineersIES – Illuminating Engineering Society
• Why is this topic important ?Energy & cost savingsCompliance may be mandatory (see http://www.energycodes.gov/adoption/states)

Controls
Scheduling• Manages lighting status based on time of day
• Complies with energy codes requiring automatic shutoff
• Good for larger open spaces
• Spaces occupied most of the time
• Areas where lights cannot be turned OFF for safety and security reasons
• Energy Savings
• Varies by application and occupancy
• Scheduling capabilities essential for load shedding energy management initiatives and demand response activities
Controls
Digital Lumen Management
• Constant lumen output over system life
• Maximizes energy savings
• Not over-lighting the space
Controls
Switching and Dimming• Individual control
• Multiuse group spaces
• On/off, bi-level, dimming
• Energy savings:
• 22% private office
• 16% open office
• 5% classroom
Controls
Occupancy Sensing• Turn off lights in an empty room
• Vacancy sensors, manual on, intelligent use algorithms embedded in some sensors
• Complies with energy codes requiring automatic shutoff
• Ideal applications
• smaller, enclosed spaces
• spaces that operate on an unpredictable schedule
• spaces that are intermittently occupied
Controls
Bathrooms/Small officesDesign Challenge
• Lights are always on, but space is mostly unoccupied
• Walls and partitions block some types of sensor technologies

• Infrared – detects motion in the space
• Microphonic – detects sound
