PURPOSE OF ECBC 2006 To provide minimum requirement for energy efficient

1. PURPOSE OF ECBC 2006 • To provide minimum requirement for energy efficient • design & construction of Bldg. CODE is mandatory for commercial Bldg/bldg complexes with (i) Connected Load of 500KW & above (ii) CMD of 600KVA & greater (iii) Air conditioned area of 1000m2 & above • APPLICABLE BULDG. SYSTEM • Bldg. space, except unconditioned storage space or warehouse • Mech. system AC, Heating, Ventilation • Service Hot water system • Interior & Exterior Lighting • Electrical power & motors Safety, health & environmental codes shall take precedence above ECBC

2. ECBC APPLIES TO New Buildings Addition to existing building Alteration to existing building • Bldg. not using electricity/fossil fuel • Equipment & portion of bldg. that use energy for manufacturing process • Multi family bldg. of 3 stories & single family bldg. ECBC do not apply to

3. LIGHTING SYSTEM ECBC Applicable Area (supply provided from bldg. service system) - Interior space of Bldg. - Exterior Bldg. features, roof , entrance, canopies, grounds etc • ECBC is not Applicable to • Emergency lighting that is automatically off during normal building • operation & is powered by battery, generator or other power source • -Lighting in dwelling units (quarters or residential in bldg. campus)

4. LIGHTING SYSTEM-MANDATORY REQUIREMENT • Automatic Lighting Shut offs • Space Control • Control in Daylight Areas • Exterior Lighting Control • Additional Control AUTOMATIC LIGHTING SHOT OFF Interior lighting of building of area greater than 500m2 shall be quipped with automatic lighting control device All office area less than 30m2, like partitions, conference & meeting rooms, school classroom shall be quipped with occupancy sensors. • For other spaces, the automatic device shall function on either • A scheduled basis at specific programmed times. An independent • program schedule for area not more than 2500m2 & not more than one floor • Occupancy sensors that shall turn the lights off within 30min of an occupant • leaving the space. Also have a wall mounted manual switch For lighting system designed for 24 hrs use shall not follow-Automatic Shut off

5. SPACE CONTROL FOR GENERAL LIGHTING Each space enclosed by ceiling ht. partition shall have at least one control device to independently control the general lighting. Each control device shall be activated either manually or automatically sensing the occupant Each control device shall control a maximum of 250m2 for spaces ≤ 1000m2 Each control device shall control a maximum of 1000m2 for spaces ≥ 1000m2 Control should be access able & located by occupant. Exception: For safety/security reasons the control may be remotely installed but it should have a pilot light indicator. The indicator may be a part of the device or Should be next to the control and clearly labeled to identify the control.

6. CONTROL FOR DAYLIGHTED AREA • Luminaries in day lighted area greater than 25m2 shall be equipped with either • a manual or automatic control device that: • is capable of reducing the light output in the day lighted area by at least 50% • controls only the luminaries located entirely within the day lighted area EXTERIOR LIGHTING CONTROL Should be controlled by a photo sensor or time switch that is capable of Automatically turning of exterior lighting when day light is available or lighting is not required

7. ADDITIONAL CONTROL • Display Lighting area > 300m2 shall have a separate control device • Case lighting used for display for area > 300m2 shall have separate control device • Hotel & motel guest rooms & suites shall have master control device at the main • room entry that controls all permanently installed luminaries & switched receptacles. • Supplemental Task lighting installed under shelf/cabinet shall have control device • Lighting for non visual applications such as plant/food warming shall be equipped • with separate control device • Lighting equipment that is for sale or demonstration shall be equipped with separate • control device accessible to authorized personnel EXIT SIGNS – Illuminated exit signs shall not exceed 5W per face EXTERIOR BUILDING GROUNDS LIGHTING – Luminaries which operates at Greater than 100W shall contain lamps having minimum efficacy 60lumen/W unless the luminaries is controlled by a motion sensor.

9. Table: 7.3.3 INTERIOR LIGHTING POWER (Space Function Method)For Hospital

10. INTERIOR LIGHTING POWER (WATTS) - By Building Area Method • Interior Lighting power allowance (in Watts) shall be determined in accordance • to the following: • (i) From Table -7.3.1 note LPD for each building area type (L1,L2,L3…) • Calculate the gross lighted floor area for each building area type (A1,A2,A3 …) • Interior Lighting Power Allowance =L1xA1+L2xA2+L3xA3… INTERIOR LIGHTING POWER (WATTS) - By Space Function Method • Interior Lighting power allowance (in Watts) shall be determined in accordance • to the following: • (i) From Table -7.3.2 see LPD for appropriate building type (L1,L2,L3…) • For each space enclosed by partition 80% or greater than ceiling ht., calculate • the gross floor area by measuring to the centre of partition(A1,A2,A3 …) • Interior Lighting Power Allowance (L) =L1+L2+L3…(sum for all spaces) • Interior Lighting Power Allowance for a Space =L x (A1+A2+A3…)

11. INSTALLED INTERIOR LIGHTING POWER It includes power used by luminaries, lamps, ballast, current regulators & control devices If two (or more) independently operating lighting system controls operation, then installed lighting power will be the highest power. Exceptions to INTERIOR LIGHTING POWER • Following lighting equipment shall not be considered when determining interior • lighting power allowance: • Display light of galleries, museums & monuments • Instrumentation lights • Medical/Dental purpose lights • Lighting Food preparation & warming equipment • Lighting for plant growth or maintenance • Lighting in spaces specifically designed for visually impaired • Retail display • Historic Landmark • Lighting for Sale & educational demonstration systems • Lighting of theatre, stage, film etc. • Athletic playing areas

12. EXTERIOR LIGHTING POWER The connected lighting power should not exceed the limits specified in Table-7.4 Exceptions to EXTERIOR LIGHTING POWER • Lighting used for exterior lighting applications is exempt when equipped with • an independent control device • Specialized Signal, directional & marker lighting associated with transportation • Lighting used to highlight features of public monuments & registered historic • landmark structures or buildings • (c) Lighting that is integral to advertising signage • (d) Lighting that is specifically designed as required by a health or life safety • statute, ordinance or regulation

13. Luminaries Wattage for Interior Lighting • Wattage of incandescent lamp shall be labeled watts • Luminaries containing ballast shall be the operating input watts of the specified lamp/ballast combination based on the values mentioned by manufacturer • Wattage of all other miscellaneous luminaries shall be the specified watt of lamps • The wattage of lighting track & flexible lighting systems that allow addition/relocation of luminaries without altering the wiring shall be the larger of the specified wattage of the luminaries included in the system or 135W/m.
