Energy Efficiency in Buildings

POLICY & STRATEGY

NTU Carbon Neutral Strategies

The five major strategies for achieving carbon-neutrality are Equipment Electrification (reducing Category 1 carbon emissions), Energy Decarbonization, Energy Conservation (reducing Category 2 carbon emissions), Negative Emissions Technologies (NETs) and Carbon Offset. The strategy of Equipment Electrification and Energy Conservation is related to Energy Efficiency in Buildings. 
 

NTU Campus Planning Principle

Article 21: The orientation of buildings should, in principle, follow a north-south alignment. If the main lighting faces east-west, the design should fully consider the building facade in relation to sunlight exposure, shading, and energy-saving functions.

Article 22: New construction projects must meet at least the Bronze level of EEWH (Taiwan's green building certification). Energy-saving designs should be incorporated at the architectural planning and design stage. Environmentally friendly methods are encouraged, with consideration given to aspects such as lighting, ventilation, shading, water resource recycling, and greenery.
 

NTU Regulations for the Energy Conservation Incentive Awards

This regulation aims to effectively reduce power consumption and encourage its faculty members and students to conserve energy.

ACTIONS

NTU Energy Conservation Working Group 

NTU had set up an Energy Conservation Working Group in 2008. The working group set up a structure to pursue energy conservation. Every department in the school is assigned a content person on matters related to energy conservation. 
  

 

Practical Measures for Energy Conservation in Buildings

NTU showcases the main measures for energy conservation in our sustainable report. Office of General Affairs also published an annual report on energy consumption and energy conservation measures. 

 

Energy Conservation Workshop

The energy conservation workshops enabled faculty, staff and students from different divisions and disciplines to gain a sound knowledge of electricity usage data and energy consumption patterns of buildings and equipment. NTU organized 12 energy conservation workshops, which were attended by 106 participants, including faculty members, students and staff from all 11 colleges.

MEASUREMENT & ASSESSMENT

 

NTU Green Building Certification

NTU have 12 buildings certified by EEWH, with 4 EEWH Silver buildings. There are nine indicators in EEWH with "Energy Saving" having the highest weighting of 32%. Energy Saving include energy-efficient building envelope (EEV), energy-efficient air conditioning (EAC) and energy-efficient lighting (EL). 

Electricity Dashboard 

The Office of Sustainability has analyzed electricity consumption in buildings and created an electricity dashboard using Tableau. The dashboard aims to identify energy consumption hotspots. NTU has identified where and when electrical devices (like AC and servers) are being used. It will be helpful in reducing energy consumption. 
 

Real-time Electricity Meter 

NTU had set up more than 600 smart meters to upload its electricity consumption every hour. These data helped the school manage NTU's electricity consumption and also identify energy waste.

 

NTU Electricity Assessment Report (2023) 

In 2023 NTU undergoes and holistic analysis of campus electricity consumption. It documented past efforts on energy wastage identification, including the collaboration with outside consultancy on 34 "Building Energy Efficiency Assessment" Reports. The biggest contribution of the 2023 report is identifying the electricity-using pattern of each building to design specific energy efficiency improvement actions for different kinds of buildings.
