Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):
kWh MMBtu
Imported electricity 32,358,320 Kilowatt-hours 110,406.59 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) 8,640 Kilowatt-hours 29.48 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):
MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy 6,877.43 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
117,313.50 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
432,223 Gross square meters

Baseline period

Start and end dates of the baseline year (or 3-year period):
Start date End date
Baseline period Jan. 1, 2018 Dec. 31, 2018

A brief description of when and why the energy consumption baseline was adopted:
In 2018, the school continued to cooperate with the government to implement energy-saving measures to achieve a significant result -- a negative growth of 4.81%.

Source energy

Source-site ratio for imported electricity:
2.50

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.25 MMBtu per square meter 0.61 MMBtu per square meter
Baseline year 0.27 MMBtu per square meter 0.65 MMBtu per square meter

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:
6.67

Optional Fields 

Documentation to support the performance year energy consumption figures reported above:
A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
1. Regularly convene energy conservation group meetings to review and plan energy saving actions.
2. Promote energy-saving measures: posting energy-saving measures in public areas and creating web-page announcements.
3. Offer energy conservation and environmental education courses.
4. hold energy-saving education training workshops.

A brief description of energy use standards and controls employed by the institution:
1. Set the air conditioner temperature to 26-28 degrees Celsius.
2. Install an air-conditioning 4 hours automatic power-off system.
3. The environmental protection volunteers inspect the energy usage of the whole school:
(1) Check whether lighting, air conditioners, electric fans, etc. are turned off during breaks or public areas and offices that are not used.
(2) Remind whether the temperature of the air conditioner is set to 26-28 degrees Celsius.
(3) Remind that the doors and windows are closed when the air conditioner is in use.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
NTNU has applied for the Lighting Energy Saving Project of the Ministry of Education and the Ministry of Economic Affairs. The energy saved can exceed 3 million kWh annually. NTNU has replaced 135,466 LED lighting equipment, and currently, 70% of the lighting on campus is energy-saving LED lights.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Solar panels were installed in the International Conference Center, annual power generation (degree) = 7.2 kwp × 2.61 (sunshine) × 365 = 6859 degrees.
The total power generated by the solar panel in the International Conference Center is 240*30=7200wp(7.2kwp). The solar power plant of Boai Building integrated with Taiwan Power Company in operation on December 30, 2020, with a capacity of 52,917.4 Wp of electricity generated by June 13, 2021. Likewise, the solar power plant of Education Building integrated with Taiwan Power Company in operation on February 2, 2021, has generated 98,184.5 Wp of electricity by June 13, 2021. The total electricity generation capacity is 151,101.9 Wp.

A brief description of co-generation employed by the institution:
Student dormitories are equipped with energy-saving HEAT PUMP water heaters that transfer heat into or move from inside the building, which need no combustion, produce no carbon dioxide, no waste heat, and reduce the greenhouse effect. Also, HEAT PUMP water heaters consume less energy than electricity, natural gas, or boiler water heaters.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Regular meetings of the Campus Energy Conservation Committee are held to review and plan for activities of the year. Each year, we allocate a budget to all units on campus to replace old air conditioners and clean the air conditioners; besides, we install 4-hour automatic power-off systems for air conditioners. In addition, we also install, replace, clean energy-saving fans. Lighting equipments of all outdoor spaces are replaced with LED lights, with 70% of the indoor space has been replaced, and is continuously in progress. The eco-volunteers are assigned to monitor and make detailed records of the electricity consumption of all units.
