GreenJump's role LEED consultant

Background

Green ASUS, built into headquarters

Founded in 1989, ASUS is the world's largest motherboard maker and one of the top three consumer notebook brands. Its Green ASUS commitment, launched in 2000, covers green design, procurement, manufacturing, marketing and service. In 2016 ASUS began the green building program for its new headquarters and appointed GreenJump as LEED consultant.

After two years of work, the new Ligong Building at ASUS's Guandu headquarters opened with LEED v4 BD+C Platinum , the highest LEED level. Mili Majumdar, Senior Vice President of the U.S. Green Building Council (USGBC), attended the opening and presented the certification plaque to ASUS Chairman Jonney Shih.

Key Strategies

How the building performs

Envelope with a low window-to-wall ratio and low-SHGC glazing to keep solar heat out
All-LED lighting with zero mercury, controlled by occupancy and daylight sensors
Variable-flow chillers, cooling towers, air handlers and pumps, with ice storage that makes ice off-peak at night and cools by day
Sub-metered energy monitoring for chillers, pumps, air handlers and cooling towers
Highly reflective roof coating, green roofs and solar panels to reduce the urban heat island effect
30% of the site as habitat green space and 30% as open space; a rainwater tank under the raft foundation handles 98th-percentile storm runoff
Drought-tolerant planting, drip irrigation and rainwater harvesting: 100% less landscape irrigation water than the LEED baseline
Construction materials with high recycled steel content and slag/fly ash; whole-building life-cycle assessment cuts five impact categories by 10% or more
More than 20 building products with EPD, HPD or Cradle to Cradle documentation
Energy recovery ventilators and MERV 13 filters, with CO₂, gas and CO sensors; a 36-day flush-out before occupancy
Bicycle parking and showers to encourage low-carbon commuting; enhanced commissioning with duct leakage tests and air and water balancing
