1 Lighting Techniques and Technology Practical Applications Britnei Godusky LC, LEED AP BD+C June 4, 2014AOBA / Current Trends in Sustainability

2 Agenda Lighting and the Energy Code: the most practical application Interior Lighting –Automatic Lighting Shutoff –Space Control –Daylighting Controls Parking Garages Exterior Lighting Lighting Techniques and Technologies Fluorescent LED Common Area Applications What’s next? 2June 4, 2014AOBA / Current Trends in Sustainability

3 Lighting and the Energy Code: the most practical application June 4, Sustainable Sites Light Pollution Reduction Energy and Atmosphere Minimum Energy Performance Building Level Energy Metering Indoor Environmental Quality Interior Lighting Control Interior Lighting Quality AOBA / Current Trends in Sustainability

4 Lighting and the Energy Code: the most practical application June 4, 20144AOBA / Current Trends in Sustainability

5 Lighting and the Energy Code: the most practical application June 4, 20145AOBA / Current Trends in Sustainability ASHRAE In addition to all new construction, the new code applies to “alteration” of even 10% of the building lighting system if the installed LPD increases.

6 Interior Lighting Automatic Lighting Shutoff – ASHRAE 90.1 Section June 4, 20146AOBA / Current Trends in Sustainability Time clock or occupancy sensors. Required for all lighting not needed for 24-hour operation or occupant safety. Manual on or automatic on to 50% power. Except: corridors and stairwells restrooms entrance areas and lobbies Automatic off requirement after 30 minutes in many spaces.

7 Interior Lighting Space Control – ASHRAE 90.1 Section June 4, 20147AOBA / Current Trends in Sustainability Each space to have at least one control device. Step control required. After hours override required for a minimum of two hours.

8 Interior Lighting Daylighting Controls – ASHRAE 90.1 Section & June 4, 20148AOBA / Current Trends in Sustainability Photosensor control required for daylight areas. -Side daylighting with windows -Overhead daylighting with skylights and roof monitors Step control required. Exceptions only where exterior obstructions are present.

9 Interior Lighting Additional Controls – ASHRAE 90.1 Section June 4, 20149AOBA / Current Trends in Sustainability Separate Controls required for: - Accent and Display lighting -Case Lighting -Guest Room Lighting -Task Lighting -Stairwell Lighting

10 Parking Garage Lighting Controls – ASHRAE 90.1 Section June 4, AOBA / Current Trends in Sustainability Reduction of power by minimum of 30% with 30 minutes of inactivity. Zones less than 3600SF. Daylight transition lighting. Photosensors required within 20’ of perimeter walls with 40% opening.

11 Exterior Lighting Controls – ASHRAE 90.1 Section June 4, AOBA / Current Trends in Sustainability Exterior lighting to be automatically turned off with presence of daylight. All building and façade lighting to be shut off at night. -Between 12am and 6am, unless operating hours extend into this time. Any additional exterior lighting to be reduced to 30% output.

12 Lighting Techniques and Technologies Fluorescent June 4, AOBA / Current Trends in Sustainability Excellent source of ambient, diffuse light. Perfect for: Fitness centers Dining Areas Perimeter Coves Vanities Utility Closets

13 Lighting Techniques and Technologies LED June 4, AOBA / Current Trends in Sustainability No reason all downlights (in any height space) shouldn’t be LED. Maintenance Cost Energy savings

14 Lighting Techniques and Technologies LED June 4, AOBA / Current Trends in Sustainability Perfect for: Exterior Lobbies Dimming Applications Linear Parking Garages

15 Lighting Techniques and Technologies Practical Applications June 4, AOBA / Current Trends in Sustainability Think about: Where do we need light? The answer is almost never “everywhere”.

16 Lighting Techniques and Technologies Practical Applications June 4, AOBA / Current Trends in Sustainability Think about: Where do we need light? -Focal points and accenting -Entrances and wayfinding -Task surfaces

17 Lighting Techniques and Technologies Practical Applications June 4, AOBA / Current Trends in Sustainability Don’t always pick the solution you’ve seen before.

18 What’s next? June 4, AOBA / Current Trends in Sustainability Digital control signals sent over existing AC power lines for lighting upgrades and retrofit solutions. OLEDs : Organic Light Emitting Diodes

19 Thank you. June 4, AOBA / Current Trends in Sustainability Britnei Godusky, LEED AP BD+C SmithGroupJJR
