The energy performance certification for buildings in Taiwan is syndicated in the EEWH evaluation system as mentioned above. The indicators include requirements and recommendations for energy performance improvements to be produced whenever a building is constructed.

At the beginning, the EEWH certification as a voluntary mechanism resulted in relatively limited applications for green building certification. In order to enhance its overall effectiveness, the Executive Yuan, the administrative department of the Taiwan government, ratified the "Green Building Promotion Program" in 2001. This initiated a mandatory EEWH evaluation for all the new publicly owned buildings with a price more than TWD 50 million (approximately USD 1,666,667). This includes schools, theater, gym, transportation stations, market, department stores, museum, library, medical facilities and government offices, among others.

The relevant requirements, including those for energy performance, will be included first in the tender documents and then evaluated at the completion and sometimes also during the construction work. The contractor’s obtaining of the completion certificate will be conditional upon its fulfillment of the goals. Through the initiative of the public sector in employing green building practices, the green building industry and its market were gradually formed.

In order to promote green buildings in the private sector, the Construction and Planning Agency of the Ministry of Interiors (CPAMI) under the Executive Yuan was tasked to institutionalize and establish relevant regulations. The CPAMI devised the "Green Building Basic Chapter" in the Building Technical Regulation, a general guideline for construction works. The chapter includes vegetation and planting, water infiltration and retention, energy saving, rainwater and grey water reuse, as well as green building materials. Nevertheless, it remains to be voluntary in the private sector and green buildings are mostly seen only in large factories or leading buildings such as Taipei 101, previously the highest building in the world during 2004-2010.

The use of green materials, however, is widely accepted and implemented in the field of interior and outdoor decoration. Pursuant to Rules of Construction Technology, it is mandatory to use at least 45 percent of green materials in each of the interior decoration work, and at least 10% in case of outdoor decoration, both in public or private sectors.

Meanwhile, the Architecture and Building Research Institute (ABRI) of the Ministry of Interiors assembled all the relevant regulations and practices, and made the Green Building Evaluation Manuals as minimum requirements and recommendations for five main types of green buildings or community, which are as follows:

• EEWH-BC: Basic version
• EEWH-RS: Residential buildings
• EEWH-GF: Factory
• EEWH-RN: Renovated buildings
• EEWH-EC: Eco-Community

Different types of green buildings focus on its respective purposes, and may not only apply the indicators developed in the EEWH system. For example, EEWH-GF also involves the energy-saving requirements for facilities and commitments from factory managements, while EEWH-RN puts emphasis on indicators of carbon-reduction and evaluation of energy cost. For EEWH-EC, the evaluation is more on the integration design and community establishment rather than a single building.

Except for construction work, a landlord may request a tenant in a green lease agreement to implement energy-saving materials, facilities or appliances for interior decoration with green building material label, green mark and water-saving or power-saving labels, which were respectively granted to the green products by the construction, environmental or energy authorities.
