Standard of good practice recommendation
• National Building Code , NBC 207:2003 (Electrical
Design Requirements for Public Buildings) has
stipulated preferential use of fluorescent luminaries
with supplemental use of incandescent lamps to
meet higher illumination level requirements
• Use of efficient lighting is recommended as
fluorescent lamps are efficient than incandescent
lamps

Government Initiative
• Government of Nepal through “Load Shedding
Minimization Action Plan 2069” has promoted use of
light efficient LED (Light Emitting Diode) lamps
- By declaring applicable Value Added Tax and
Customs Duty free on import of such goods

Government Initiative
• “ National Electricity Crisis Mitigation Action Plan 2065”
introduced by Govt. of Nepal, provision to promote energy
efficient lighting :
•
A. To provide CFL to every electricity consumer,
by – i. Providing CFL to every consumer immediately as
per “Buy one get one free” scheme,
ii. Establishing CFL Fund,
iii. Contributing NRs. 50 million each from
Government of Nepal and Nepal Electricity
Authority,
iv. Making customs and VAT free on CFL, LED,
slim tubelight and electronic ballast

Government Initiative
•
- B . To discourage use of high energy consuming lamps
(incandescent lights)
- by continuously discouraging production, import and
sales of high energy consuming incandescent lights,
-
-C. To launch public awareness campaign
by i. Producing informative audio visual materials on
Demand side management,
ii. Advising through radio, television, newspaper
iii. Advertising at public places with pamphlets

Government Initiative
• -D. To formulate policy on energy audit of industry, and start
energy auditing on hotel, large industry, govt.
institutions
and commercial buildings,
• - E. To use CFL and LED lamps in hotel, large industry, govt.
institutions and commercial buildings and to use
occupancy sensors in big hotels,

Efficient Lighting aspects
• Use of higher efficient lamps and luminaries
• Use of occupancy sensor to conserve energy
• Use of photoelectric sensor to get advantage of daylight
• Use of dimmer to adjust light levels
• Use of multistage light switching to varying need of light levels
• Purpose of efficient lighting being optimum use of energy to
meet user satisfying light levels conserving avoidable energy
losses

Nepalese experience on Efficient Lighting aspects
• Use of higher efficient lamps and luminaries
- Government recommend use through action plans
- Being used in government institutions, hotels,
industries, commercial institutions
- With government subsidy, Nepal Electricity Authority
implemented CFL distribution to consumers in “buy one
get one free” scheme
- Mostly imported from abroad
- Higher upfront cost make rural household difficult to
afford

Nepalese experience on Efficient Lighting aspects
• Use of occupancy sensor to conserve energy
Government recommend to use in hotels
Not popular in residential use
Technology new to handle for technicians
Gaining application in hotels, offices
Good prospects to use, but need financial viability

11
Nepalese experience on Efficient Lighting aspects
• Use of photoelectric sensor
Good prospect to use in Nepal with good
solar irradiance
Architect need to work closely with lighting
designers
Higher initial cost make difficult to afford
The Transition to Efficient Lighting in South Asia
12
Nepalese experience on Efficient Lighting aspects
• Use of dimmer to adjust light levels
Comparatively more popular in use
Easier to commission and maintain
Initial cost not so high
Suitable to use in light to medium energy
density applications
The Transition to Efficient Lighting in South Asia
13
Nepalese experience on Efficient Lighting aspect
• Use of multistage light switching
Suitable to use in multi task applicable
venues, high power density applications
Sophisticated lighting design requirements
Being used in hotels, auditoriums,
industries, commercial houses
Difficult to afford for residential application

14
Technical Capacities
• Good network of products (lamps) supplier
• No research institution destined for lighting development
• Limited skilled manpower on good lighting design and
installation
• Less formal training opportunity on latest design concepts for
engineers
• Strengthening design , installation and operational capacity for
efficient lighting is need of time

15
Financing the Transition
• Government of Nepal supporting transition through financial
benefits such as providing VAT and customs duty free on
efficient light lamps
• Investment for continuous manpower development on efficient
lighting design is essential
• Focused training for engineers in lighting design required
• Local production of efficient light goods should be encouraged
