Project Abstract

Huachiew Chalermprakiet University opened in 1992. The university has 886 staff many of whom have been working with the university from its early days. The university working days are from Monday to Saturday (3,744 hours per year). Aside from maintaining full-teaching operations, the university also strives to have impeccable green credentials through a low energy consumption profile.
From 2012 to 2015, the university has engaged in an energy saving program and this has resulted in reduced energy consumption. To achieve the goal of energy efficiency, Huachiew Chalermprakiet University has created a culture of energy saving in all levels of university operations. We have encouraged employees to be personally involved in energy conservation activities. There are team members, who lead the campaign to reduce the carbon footprint. It started with energy conservation training for every staff so they could guide others and apply their know-how and skills in their working routines. We also encourage students to join the campaign by using energy economically, during student activities within the university. Then there are also ongoing outreaches to the community. Activities are conducted to educate students about energy saving as part of our corporate social responsibility program.
For the past four years through energy conservation activities (both investment and non-investment), we have reduced energy consumption by more than 2,620,435 kWh, which is equal to 1,903.79 tons of CO2 emissions. The reduction of energy consumption gave us a total savings of over 10.99 million baht with the average ROI of 3.37 per year. Recently, Huachiew Chalermprakiet University was awarded the Best Energy Saving Building of MEA 2015 from the Metropolitan Electricity Authority of Thailand with prize money of 2 million baht. Also we were honored at the Thailand Energy Awards 2016 and ASEAN Energy Award 2016.
A culture of energy saving was not easy to create but at Huachiew Chalermprakiet University, WE CAN. It is our firm belief that our success story is driven by our staff, who is committed to the energy conservation program.

 

Strategy

Inspiration

From H.M.King Bhumibhol Adulyadej’s words in June 24, 1994, “May you manage the university along the path of righteousness.”, we reminded ourselves in thinking, speaking and doing to follow our King’s words. We aimed to apply his words in conducting our energy conservation projects.

“May you manage the university along the path of righteousness.”

Clearness to Sustainable Energy Saving

Participation is the heart of success at Huachiew Chalermprakiet University. Our energy conservation achievement originated from our directors and managers, joined by our staffs, students and other organizations. These various parties have driven energy conservation policies and activities, and then eventually became Huachiew Chalermprakiet University’s culture in energy conservation. We also established policy committees, energy management committees and energy audit committees. We have many energy conservation activities which were succeeded by participations from every level of Huachiew Chalermprakiet University’s people. Some of these projects are the “Bike, Grow, Save” and R2I Project.

fig2

Huachiew Chalermprakiet University is guided by Assoc. Prof. Dr. Prachak Poomvises who committed to “RUN THIS UNIVERSITY WELL” and the “6 Huachiew Chalermprakiet University virtues”. This eventually became our “VIRTUE ENERGY CONSERVATION”. We also have concrete policies and clear goal in mind. Along with our staff, continuous funding and evaluation, we can accomplish energy conservation activities. Together with a systemic energy management, Huachiew Chalermprakiet University has been successful in attaining sustainable energy conservation.

fig3

In order to reach our energy conservation goal, Huachiew Chalermprakiet University had announced energy conservation policies and established organizations to drive these policies and do actions in energy conservation. These organizations were established from every level of Huachiew’s staffs, supported by sufficient funding from the university with continuous evaluation and development. Not only we focused on finding appropriate energy saving policies and actions, but we also created a culture of organization in energy conservation by encouraging teamwork, educating and training. Thus, our people can apply energy conservation to their works and lives.

Innovativeness

1.Classroom Energy Monitoring 

Huachiew Chalermprakiet University has installed energy monitoring device in our classrooms which will enable us to manage our classrooms more efficiently. In the near future, we will be able to adjust our classrooms and the number of students in those class to optimize energy consumption.

fig6

2. Green Bus Station and Energy Saving Security Point

Aiming to elevate scenery in Huachiew Chalermprakiet University, we have planted many trees and plants in our campus. These trees and plants do not only make our university livelier, but also reduce solar heat transfer to our facilities.

fig7

3. Loss Nay Installation

Indoor Air Quality is a crucial factor for our students learning capacity. Hence, we have installed Loss Nays or Air Exchange Machine in our classrooms. These machines do not only increase our classrooms’ indoor air quality, but they also reduce energy consumption in those classrooms.

fig8

4. Student Scholarship from energy saving

In doing energy conservation, we believe that these benefits will, at last, be given to the next generations. At Huachiew Chalermprakiet University, those money savings from our energy conservation projects will be given as scholarships to our students.

fig9

For over 5 years of energy conservation, we have funded more than 34.15M Baht investment in peopleware, systemware and hardware. These have resulted in a total energy saving of over 2,620,434 kWh.

Replicability

Establishment of Organization of Energy Management

Huachiew Chalermprakiet University has established an energy management organization since 2011, in order to succeed in its sustainable energy conservation goal. The organization consists of the Chairman of Energy Management who is Assoc. Prof. Dr. Prachak Poomvises himself, the Board of Committees who apply policies into everyday works, sub-committees who analyze and develop energy saving projects and a working group which is consists of various people from each department.

fig11

Employee Development and Educational Training

At Huachiew Chalermprakiet University, we have continuously educated our people in energy conservation. Focusing on every level of our staffs and students, our people had a clear understanding about energy conservation which will lead to firm energy conservation awareness. In order to do so, we invited specialists in energy conservation from the Ministry of Energy and energy consultant firms to educate and train our people in energy conservation. We also observed and learned from other successful organizations, and brought and applied those knowledge to our organization; some of them can even be applied at our staff’s house.

Applicabilities and Knowledge Management

To succeed in energy conservation and make it applicable with everyday works, we conducted innovative energy saving contests (R2I: Routine to Innovative for Energy Saving) to encourage our staffs and students to apply energy conservation ideas in their lives.

fig13

These projects resulted in reduction in energy costs, work processes, man-hour and energy consumptions. In order to enlarge the sphere of impact from this knowledge, Huachiew Chalermprakiet University conducted a seminar to present and discuss each of the ideas, with Miss Laksawan Wongworrakan, the director of Richmond Hotel as the guest speaker on “Energy Saving Success in a Hotel Facility. We also received honor from Mr. Sanit Ungsusint, the Vice-President of Metropolitan Electricity Authority to open the seminar, which was participated by more than 50 organizations.

Practicability

In evaluating the results in energy conservation, apart from the total energy saving, Huachiew Chalermprakiet University evaluated the Specific Energy Consumption Index (SEC Index). This indexes consist of (1) Total Heat Energy (MJ)/Area (sq.m.), (2) Total Electricity (kWh)/ Staffs and Students (Person), and (3) Total Electricity (kWh)/ Area (sq.m.). Due to our energy conservation policies and projects, Huachiew Chalermprakiet University’s energy conservation and SEC Index have continuously reduced since 2012.

fig18

Cost-effectiveness

Huachiew Chalermprakiet University has done various energy conservation activities, both non-investment and investment projects. In non-investment projects, we focused on creating energy conservation awareness. Thus, our staffs and students can practice and pass on these ideas to the society. For investment projects, we considered three aspects: (1) RESULTS (Sustainable and Consistency), (2) ROI (Return on Investment) around 3-5 years, and (3) SUBSIDY from the government.

From 2013-2015, Huachiew Chalermprakiet University reduced energy consumption by more than 10.99M Baht with an average ROI of 3.11 years, and with subsidy from DEDE Subsidy 80:20 Project. Huachiew Chalermprakiet University also considered projects with ROI of over 5 years, but be able to become learning centers in energy conservation.

Consistency

To encourage staff to participate in energy saving programs, Huachiew Chalermprakiet University has conducted various activities to develop three mains drivers of energy saving, which consist of three distinct wares as follows:

Photo-17

Employee development (Peopleware): This part was developed through annual energy saving training and “6 Virtues” development activities. These six virtues comprised of diligence, patience, thriftiness, merciful, honesty and gratefulness.

System set-up (Systemware): Through staff collaboration, Huachiew Chalermprakiet University has planned to receive ISO50001-Energy management within this year, which has standardized our sustainable energy saving program.

Efficiency (Hardware): Systems were fine-tuned. It will ensure that energy, supplied, is efficiently consumed and machines and systems are correctly maintained. Along these processes, development plans are considered under the criteria of “ROI period of less than three years”

Environmental Effect

  • Reduction of CO2 Emission due to Energy Saving Plans
    Since 2011, Huachiew Chalermprakiet University can reduce CO2 emission by more than 1903 Tons of CO2 from its total energy consumption. We also launched the “Clean Bicycle Project” which totally replaced motorcycle usage in our campus. The project was initially started with only 100 bicycles, given to Huachiew Chalermprakiet University by our alumni who graduated in that year. Now, there are over 500 bicycles available in every corner of Huachiew Chalermprakiet University’s campus. This project not only reduced CO2 emission by motorcycles, but also pollution, sound and risks from accidents and crimes in our campus. Huachiew Chalermprakiet University also provided 6 electrical shuttle cars which our staffs and students board from building to building. These cars were named after the six virtues of Huachiew Chalermprakiet University to remind those who use them about what drives our organization.

Clean Bicycle Project

  • Waste and Pollution Management
    Pollution and waste are by-products of human activities. Having this awareness, Huachiew Chalermprakiet University analyzed our activities to reduce these by-products. One of our achievements was 100% reduction of foam material in our cafeterias and replacing them with degradable ones. From this success, we initiated other activities in Huachiew Chalermprakiet University to reduce the consumption of foam as well. We were also awarded World Class Standard Mass Catering by the Food Institute (WHEN), Department of Industrial Works. This indicated our success in our waste management project, such as personal waste management and bacteria bank which can be used in cleansing processes. Huachiew Chalermprakiet University also aimed to reduce our paper consumption. Starting in 2010, we reduced our paper cost by more than 85.5% or equivalent to 2.3M Baht.

Recycling

Huachiew Chalermprakiet University has applied the 3R processes in our waste management. These 3R consist of:

REDUCE – We encouraged our staffs and students to reduce paper consumption through various projects such as applying online system in booking and doing polls, and sharing meeting documents by e-mail instead of the printed-out version.

REUSE – At Huachiew Chalermprakiet University, our people use both sides of the A4 paper. We also apply “REUSE” concept in other fields such as using left over materials in gardening and watering our plants by water from the canal in the campus.

RECYCLE – We have performed waste management in order to recycle our wastes into different kinds of usable materials and develop those wastes to become products. By doing so, we can reduce some of our material costs.

Completeness

Success in energy saving was not made by a single person, but by collaboration and the efforts of all staff of Huachiew Chalermprakiet University. We owe our success to the teamwork and active education/training of our staff and students, which have eventually created a culture of energy saving at all levels of University operations.

Benefits

An immediate benefit was the saving of 2,620,435 kWh in energy consumptions, which was equal to 1,903.79 tons of CO2. This translated into a substantial financial savings of 10,990,409 baht. However, the most valuable long-term benefit has been the opportunity to inspire staff at all levels to adopt energy saving as their own campaign. This resulted in creativity at the individual and team levels that did not only increase daily energy saving, but also enhanced life quality for our personnel and students. We are ready to share what we learned and support other organizations on their journey to sustainable energy success. At Huachiew Chalermprakiet University, we are honored to contribute to Thailand’s green initiatives. Our ultimate goal is to play our part to conserve energy and make the world a better place for the benefit of the next generation.
