EEWH
TAIWAN'S GREEN BUILDING
RATING SYSTEM
What is EEWH?
EEWH (Ecology, Energy Saving, Waste Reduction, and Health) is Taiwan’s official green building certification system, developed by the Ministry of the Interior.
EEWH provides a comprehensive framework for improving building environmental performance, resource efficiency, and occupant health, while aligning closely with Taiwan’s regulations, climate conditions, and sustainability policy objectives.
It is widely adopted across public and private sector projects and serves as a recognized benchmark for sustainable building performance in Taiwan.
EEWH Rating Systems
EEWH applies to a range of building types and development stages, with assessment criteria structured around environmental performance categories.
EEWH BC
Building Construction
Applicable to most new construction projects and general building developments.
This is the standard EEWH framework covering ecology, energy saving, waste reduction, water conservation, and indoor environmental quality.
EEWH RS
Residential
Designed for residential buildings and accommodation facilities.
This category addresses sustainability strategies specific to housing developments and living environments.
EEWH GF
Factories & Industrial
For industrial buildings and factory facilities.
The criteria reflect the operational characteristics and environmental considerations unique to manufacturing and industrial projects.
EEWH RN
Renovation & Existing Building
For existing buildings undergoing improvement or retrofit.
This category focuses on enhancing environmental performance, energy efficiency, and indoor environmental quality in operational buildings.
EEWH EC
Eco-Community
For community-scale developments.
This assessment expands beyond individual buildings to address broader ecological planning, infrastructure, and environmental integration at the neighbourhood or district level.

LEED & EEWH
Integrated Certification
In Taiwan, sustainability strategies often involve both LEED and EEWH certification.
LEED is internationally recognized and commonly used by multinational corporations and global investors to demonstrate ESG alignment and sustainability leadership.
EEWH is Taiwan’s national green building rating system, aligned with local regulations and policy requirements.
Many projects therefore pursue dual certification to meet both international and local expectations.
RCI specializes in integrated certification strategies, aligning LEED, EEWH, WELL, and other rating systems from early design to avoid duplication, reduce complexity, and improve overall building performance.
This coordinated approach allows project teams to achieve multiple certifications efficiently while maximizing long-term value.
