Energy Efficiency

Based on Lighting

   

             

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. GENERAL OFFICE

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. LOBBY (RENDERING)

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. MAIN LOBBY

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.
