Energy savings of up to 80% can be achieved with modern lighting. This does not change the brightness levels or aesthetics. In Hotel projects changes in lighting can deliver 15-20% overall electrical savings

SHELL SHARED SERVICES CENTRE (2008/2009)
Location: Makati City, Philippines
Baseline and New technologies :
• 8.7 W/sqm (with decorative lighting) at 500 lux average on work areas
• First LEED project in the Philippines
• Project achieved LEED Silver Certification (with maximum LEED points for lighting)
• DALI dimmable system with daylight and presence detectors
Yearly savings (USD) vs. Ashrae baseline:
$765,000 (incl. decorative lighting), $840,000 (w/o decorative lighting) – including AC
Entire project cost: $22 million
ROI: 13 months (incl. decorative lighting), 11.6 months (w/o decorative lighting)
Shell Shared Services Center serves as an information hub for all its international affiliates
and clients. Operating 24 hours, 7 days a week, the building features an efficient smart
lighting system. Operated by sensors, the system determines whether there is sufficient
lighting on the work areas or turns-off certain areas where human activity is no longer
present.
The whole project gained Silver Certification, and TELCS achieved maximum points in
lighting, making it the first LEED project in the Philippines. A 37% reduction of lighting power
consumption (vs. Ashrae 2004) was achieved by using high efficient and low glare lighting
fixtures. This results in cost savings of almost 1 million USD a year compared to a standard
lighting layout.

Sofitel Philippine Plaza Manila (2010)
Location: Manila, Philippines
Baseline:
• ROI of 8 months (excluding air-con savings)
• 79% savings in electricity = $52,000 savings in first year (including air-con),
$89,000 each in successive years
Yearly savings in kW and USD:
• 323,000 kW (79%) = $59,000(excluding AC)
• 484,000 kW (79%) = $89,000 (including AC)
Cost: $37,000 for light fixtures and installation
The Sofitel Philippine Plaza is a 5-star hotel which needed a dimming system in the lobby
and lounge area (24/7 operation). TELCS findings showed it to be more cost effective to
change the existing lighting system to an energy-efficient system, before installation of a
dimming system.
The change to more efficient light fixtures decreased the cost of the dimming system from
11,500 USD to 4,500 USD and lowered electricity consumption by 79%. The hotel
achieved $52,000 additional net profit in the first year, and $89,000 in successive years
due to the energy savings.

SUNPOWER FAB 3 (2009 - ongoing)
Location: Malaysia
Baseline:
• 5 watt/m2 power consumption (compared to the layout of a major global lighting
brand with 10.70 watt/m2),
• average 400-500 lux on workplane areas
• First LEED project in Malaysia
• Platinum LEED Certified and Maximum LEED points for lighting and energy
Entire project cost: $1 billion USD
Sun Power Corporation, one of the largest manufacturers of solar cells worldwide, builds 12
hectares air conditioned production facilities and a 2ha office, on a 48 hectare lot in Malaka,
Malaysia. Both factory and office have to achieve platinum LEED certificate.
The initial lighting layout done by a major lighting producer would have made the goal of
achieving platinum LEED for the plant impossible.
TELCS was chosen to provide cutting edge-efficient lighting layouts for maximum
illumination levels at minimum electrical consumption. It achieved a reduction of more than
50% compared to the initial layout and thus achieved maximum LEED points for the
project.

PHILIP MORRIS WAREHOUSE (2009/2010)
Location: Taguig City, Philippines
Baseline:
• 80% lower electricity consumption (65% savings measured in first month) Increased
brightness level
Yearly savings (USD): $17,000
Cost: $16,300
ROI: 12 months
Philip Morris' facility consists of six (6) warehouses, operating 10 hours a day, each having
741 square meters of floor space. The previous lighting set-up of 250W mercury bulbs and
inefficient 40W fluorescent bulbs, consumed 32.5 kW/h with an average of 50lux
illumination.
TELCS changed the facility to 5.6kW/h with increased light levels on workplane and on the
vertical plane for better readability of printed words. The average lux level was increased
to minimum of 65lux and maintenance cycles increased from 2months to 4 years.
