This project is planned and reviewed according to the Ministry of the Interior's EEWH standards, defining "green building" as "ecological, energy-saving, waste-reducing, and healthy buildings." Quantitative standards are used to assess whether buildings are environmentally friendly. These four main directions are divided into nine major assessment categories, serving as the core of the latest green building evaluation.
Ecology
Biodiversity Index, Greenery Index, Site Water Retention Index
Energy Saving
Daily Energy Saving Index*
Waste Reduction
CO2 Reduction Index, Waste Reduction Index
Health
Indoor Environment Index, Water Resource Index *, Sewage and Garbage Improvement Index
* These are the essential threshold indicators.
Taiwan Green Building Certification System

Green Building Label：
Refers to the label obtained for buildings with occupancy permits or existing legally constructed buildings that have been reviewed and approved to meet the Green Building Assessment Index Standards, and have obtained certification approved by the Ministry of the Interior. The validity period is 5 years.
Label Grading：
The grading system consists of five levels: Diamond Level for scores above 95%, Gold Level for scores between 80% and 95%, Silver Level for scores between 60% and 80%, Bronze Level for scores between 30% and 60%, and Qualified Level for scores below 30%.

Green Building Label Assessment Summary
Energy Efficiency Index for Building Envelope
For buildings below 800 meters above sea level, the following two methods can be considered for evaluation
1. Total Quantity Control：
(1) Visible light reflectance of glass (Gri) <= 0.20
(2) Roof thermal insulation (Uar) < 0.80 (w/㎡.k)
(3) Skylight glass coefficient (glass ηi value required according to area size)
(4) ENVLOAD < 121 (Central Region Standard)
2. Subdivision Control:
(1) Visible light reflectance of glass (Gri) <= 0.20
(2) Roof thermal insulation (Uar) < 0.80 (w/㎡.k)
(3) Skylight glass coefficient (glass ηi value required according to area size)
(4) Average heat transfer coefficient of external walls (accommodation type) Uaw < 2.75 (w/㎡.k)
Average heat transfer coefficient of external walls (other types) Uaw < 2.00 (w/㎡.k)
(5) Average heat transfer coefficient of windows (Uaf required according to window opening rate)
(6) Average shading coefficient of windows (SF required according to window opening rate)
EEV=【(EVc-EV)/(EVc-EVmin)】=0.23. Housing energy consumption RS41=11.3×EEV=11.3×0.20=2.57
CO2 Reduction Index
■ Rationalization of Structure
Building layout and facade adhere to regulatory principles, striving for simplicity and uniformity in facade design.
■ Lightweight Construction
Lightweight partitions are utilized.
■ Durable Design
Visible piping design for plumbing systems.
■ Use of Recycled Materials
High-performance concrete and blast furnace cement are employed as concrete materials, and recycled cement bricks are used for outdoor flooring surfaces.
Waste reduction
■ Unbalanced Earthwork in Construction
Minimize basement excavation and use excess soil for on-site landscaping and backfilling to reduce environmental impact.
■ Recycled Building Material
Utilize high-performance concrete and blast furnace cement to reduce concrete usage.
■ Construction air pollution control
•Cleaning measures – Construction sites are equipped with washing facilities dedicated to construction vehicles and earthmoving machinery.
•Sludge sedimentation and filtration treatment measures - Measures are implemented for sedimentation, filtration, sludge removal, and drainage for wastewater from cleaning vehicle sludge, earthmoving machinery, and underground construction wastewater.
•Vehicle Road Dust Prevention – Install steel plates or lay concrete across the entire roadway.
•Water spraying - Spraying water on the roads used by vehicles on the construction site.
•Water spraying - Spraying water on the stockpile areas
•Water spraying - Spraying water on the exposed surfaces at the construction site
•Dustproof netting - Prior to leaving the construction site, cover the transporting truck with non-permeable dustproof plastic sheeting.
•Dustproof netting and other measures - Install dustproof netting on structures after construction.
•Dustproof fencing and other measures - Erect fencing around the perimeter of the construction site, with a height of over 1.8 meters.
•Dustproof covering - Implement measures such as vegetation planting or spraying chemical dustproof agents on excavated areas or material piles.
PI=PIe+PIb+PId+PIa-β=1.5(Earthwork Transportation)+1.0(RC structure)+0.0(concrete)+(1-0.48)(air pollution control)-0.0=3.02
RS6=13.13×【(3.30- PI)/3.30】+1.5= 2.61
Precautions
1.Photos of air pollution prevention measures A total of 8 items must have photos, and each item will be scored accordingly.
2.Enhanced Scoring Standards for Blast Furnace Cement and High-Performance Concrete (2019 Version)
Indoor Environment
■ Sound Environment
Employ airtight glass windows with a rating of Class II or above and enhance the mass per unit area of wall panels to ensure effective soundproofing.
■ Ventilation and Lighting Environment
Utilize clear glass with good light transmission for ventilation and lighting, with anti-glare barriers and lampshades in living spaces, and equipped with a fresh air supply system.
■ Interior Building Materials and Decoration
Adopt minimal decoration to conserve Earth resources, and use building materials with green building certification to reduce indoor air pollution sources such as formaldehyde and low volatile organic compounds.
Water Resource Indicators
■ Water-saving Equipment
All toilets and public faucets must fully adopt water-saving equipment with water-saving certification or equivalent water usage specifications, including dual-flush toilets with Grade 2 water-saving certification, sensor-operated urinals, and automatic sensor faucets.
■ Rainwater Reuse System (Projects with floor areas less than 20,000 square meters are exempt from assessment.)
All green areas will be equipped with water-saving irrigation systems. Rainwater storage tanks will be installed underground, primarily collecting rainwater from rooftops. After treatment, the collected rainwater will be used for plant irrigation.
