Green By Design

"Healthy world, one tree at a time."

The Beauty of Green

A green factory is defined as a building that consumes minimal resources of the planet and produces the minimal waste. The goal is to minimise impact on the environment and the health of the people working there.

Our building’s entire life cycle – location, design, construction, use, maintenance, and demolition – is based on the efficient, mindful use of natural resources and on providing a beautiful, pleasant working environment. We are guided by these Nine Green Building Indicators established by Taiwan’s National Council for Sustainable Development under the Ministry of the Interior (MOI).

We do this not for praise or recognition – though we’re humbly appreciative of these. We do this because the earth is our home, because its people are our friends and family, because its life forms are the air we breathe. So, we start with ourselves, and strive to create the ripple.

Green Building Indicators

Expand All
  • (1) Biodiversity Indicator

    Measures a building’s viability as a habitat and place of interaction for the plants and animals native to the site.

    Intenza factory:

    • Man-made wetland
    • Protected stream eco-system
    • Use of natural soil and ecologically-engineered nature fence
  • (2) Greenery Indicator

    Assesses total carbon dioxide (TCO2) levels after completion of planting trees and/or other greenery. TCO2 must be greater than the original, pre-planted, levels.

    Intenza factory:

    • Planted 200 trees and 5,000 shrubs creating a park-like green space


  • (3) On-site Water Retention Indicator

    Compares water retention capacity of the site pre- and post-development. At a minimum, the developed site must retain no less than the site prior to development.

    Intenza factory:

    • Retention pond conserves water during high rainfall
    • Provides flood prevention


  • (4) Daily Energy Savings Indicator

    Analyses glare control of glass surfaces, shading requirements, insulation, air conditioning, lighting.

    Intenza factory:

    • Utilises solar power
    • Use of natural sunlight – skylights and windows reduce need for lightbulbs
    • High ceilings, open windows allow natural airflow and reduce need for air conditioning



  • (5) CO2 Reduction Indicator

    Assessed under four categories: rational structure, lightweight structure, building durability, and use of recycled building materials.

    Intenza factory:

    • Simple, yet structurally sound, building
    • Minimal concrete usage
    • Construction practices minimised CO2 emissions
  • (6) Construction Waste Reduction Indicator

    Includes minimising of construction waste, demolition waste, and air pollution during construction.

    Intenza factory:

    • Use of recyclable building materials such as steel
    • Retention of indigenous soil onsite during construction
    • Preservation of indigenous ponds onsite during construction
  • (7) Indoor Environment Indicator

    Evaluates inside environment for light, sound, ventilation, and eco-friendly interior finishing.

    Intenza factory:

    • Clean, well-ventilated air
    • Low noise levels
    • Eco-friendly paint
    • Toxin free
  • (8) Water Resource Indicator

    Measures use of water-saving irrigation systems or rainwater/greywater recycling systems including water-saving toilets, taps, and other mitigating measures.

    Intenza factory:

    • Reclaimed rainwater
    • Sustainable landscaping irrigation system
  • (9) Sewage & Garbage Improvement Indicator

    Measures sewage improvements to drainage, maintenance, and management of daily wastewater. Measures garbage-handling improvements for aesthetic and sanitary qualities.

    Intenza factory:

    • Waste recycling
    • Waste water recycling
    • Kitchen waste
    • Artificial filter (sewage purification)
