ASHRAE 90.1-2010In 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 LightingAutomatic Lighting Shutoff – ASHRAE 90.1 Section 9.4.1.1


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

restroomsentrance areas and lobbies

Automatic off requirement after 30 minutes in many spaces.

7

Interior LightingSpace Control – ASHRAE 90.1 Section 9.4.1.2


Each space to have at least one control device.

Step control required.

After hours override required for a minimum of two hours.

8

Interior LightingDaylighting Controls – ASHRAE 90.1 Section 9.4.1.4 & 9.4.1.5


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 LightingAdditional Controls – ASHRAE 90.1 Section 9.4.1.6


Separate Controls required for:- Accent and Display lighting- Case Lighting- Guest Room Lighting- Task Lighting- Stairwell Lighting

10

Parking Garage LightingControls – ASHRAE 90.1 Section 9.4.1.3


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 LightingControls – ASHRAE 90.1 Section 9.4.1.7


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 TechnologiesFluorescent


Excellent source of ambient, diffuse light.

Perfect for:Fitness centersDining AreasPerimeter CovesVanitiesUtility Closets

13

Lighting Techniques and TechnologiesLED


No reason all downlights (in any height space) shouldn’t be LED.

Maintenance

Cost

Energy savings

14

Lighting Techniques and TechnologiesLED


Perfect for:

ExteriorLobbiesDimming ApplicationsLinear Parking Garages

15

Lighting Techniques and TechnologiesPractical Applications


Think about:

Where do we need light?

The answer is almost never “everywhere”.

16



Think about:

Where do we need light?

- Focal points and accenting- Entrances and wayfinding- Task surfaces

17



Don’t always pick the solution you’ve seen before.

18

What’s next?


Digital control signals sent over existing AC power lines for lighting upgrades and retrofit solutions.

OLEDs : Organic Light Emitting Diodes
