1. code calculations, construction drawings
and elevation/section graphics…

2. rendered ELEVATIONS AND BUILDING SECTIONS

11. cap energy usage
vary by state
vary by project type
Code calculations

12. Energy Consumption
Lighting consumes ~23% of the electricity used in all buildings
~20% of electricity required for air-conditioning results from heat generated by lamps
~ ½ electricity used in commercial buildings is for lighting systems
~10% of electricity consumed in residences is used for lighting

13. life cycle consumption standards
ASHRAE, LEED, etc.
Cradle to cradle, energy star, etc.
hazardous material disposal
planning: HVAC and daylighting integration

14. Light Pollution and Trespass
Excessive glow of light in night sky
excess lighting; sources aimed in inappropriate directions
dark sky society
Light trespass:
Glare onto an adjacent property

15. The Massachusetts Energy Code

16. Lighting Power Density (LPD) Maximum Power Usage
Code specifies numeric maximum
By Occupancy type
Watts/sq. ft.
Use formula from Code
Use Room finish schedule
Add up totals from RCP, total watts per luminaire
Adjust fixture total or lamping appropriately if you’re over

17. From CMR 780

21. calculations using schedule

22. construction drawings

23. lighting equipment schedule

26. most typical fields: Letter Symbol (from RCP)
Type (mounting + lamp + distribution)
Lamp (col’s for number and wattage)
Manufacturer
Catalog number

37. ACT meeting GWB wall

38. ACT hung off structure

39. Dimming/Switching Plans
indicate location of controls and groupings of fixtures onto circuits
Dimming/Switching Plans

40. Switching: Considerations
Consider location and appearance of controls
Consider fixture grouping
Consider operation
Switched, dimmed, remote controls, PDA controls
Pre-set scenes at control
Pre-set scenes at central dimming station, computer interface, or telephone activation
Consider operators

43. Systems coordination structural system limitation
HVAC system implications

46. Steel yourselves

47. Concrete systems

48. Most restrictive

49. Heating and A/C symbols

50. Air systems: how they work

51. Mechanical Plans from the Engineer

52. You need the duct sizing and register locations

53. Diffusers

54. Supply air diffusers

55. Linear diffusers and return grilles

56. average dimensions

63. Sprinkler spacing Rule of Thumb
7’5’ maximum from side walls
15’ OC maximum

64. Alarms: NFPA 72 indicates where needed

65. Other rules of thumb

66. Wireless Wireless repeaters Every 150’ within direct line of sight
50’ through interior partitions
Not at all through masonry/exterior walls
Library stacks are worst

67. A/V equipment TV’s, projectors, etc
Sight lines are critical (for viewer and projector)
Speakers:
Coverage varies greatly by system
One in a room
Wall or ceiling mtd
Stereos, CD’s, etc: within the room

68. Smoke and/or fire detectors
One in every enclosed space
One every 50’
Heat and/or optical sensitivity
Hard-wired
Fire detectors required in some specific occupancies (hazardous)

69. Exit signage and lighting
Wall or ceiling mtd; can be lit internally
At every exit door
Every 100’
Battery-powered lights
Strobe lights with audible alarms in bathrooms and egress corridors

72. Smoke detectors Hard wired At least 1 in all occupied spaces
Every 30’/900sf
Inside ductwork

73. Manual fire alarms Within 5’ of all exits Specific height
Must not project into space more than 4”

74. Visible/audible alarm signals
Within 5’ of all exits
Along path of travel

75. Fire extinguishers Within 30’ of cooking equipment
Buildings under construction
Open flames
Labs, computer rooms, generator rooms

76. so for this project… generate the schedule
manufacturer’s data for decorative only
all lighting equipment included
include exit signs (find a product)
use schedule to calculate LPD
switching plan with Key
