“Green Hospitals Project” Registered as a JCM Project in Vietnam
-The Demonstration Project of Energy Management System in Vietnamese Hospital-

December 9, 2015
New Energy and Industrial Technology Development Organization (NEDO)

Under the Joint Credit Mechanism, “Green Hospital Project” was registered as a JCM project.

This demonstration project has introduced about 1,000 energy efficient inverter air conditioners (ACs) at two state-owned hospitals in Vietnam, along with energy management systems to optimize these ACs efficiently. The project aims to demonstrate and verify these technologies as well as CO2 emission reduction effects, anticipating a 35% energy saving as well as better ventilation of the entire hospital.

1.Project Summary

In Vietnam, the energy efficiency labelling program was introduced in 2013 to popularize energy-saving products. NEDO and Ministry of Industry and Trade (MOIT), Vietnam, signed a memorandum of understanding (MOU) in August, 2014, and have been working together on a demonstration project to enhance the energy efficiency of the two hospitals through their respective energy management systems.

On November 30th, 2015, “Green Hospital Project” was approved and registered as a JCM project.

In this demonstration project, high efficiency performance inverter ACs, compliant with the energy efficiency labelling standard in Vietnam, were introduced in two state-owned hospitals, one located in Hanoi and the other in Ho Chi Minh City. Not only were the inverter ACs installed, but energy management system (EMS) was developed and installed to enhance the energy efficiency of the respective hospitals. Together with the EMS, improving the ventilation leads to a better indoor air quality, thus contributing to changing these hospitals into environmentally friendly “green hospitals”. As a JCM Project, the EMS will be monitored for one year and the amount of CO2 emission reduction as well as energy efficiency effect will be verified.

In Vietnam, Cooling Seasonal Performance Factor (CSPF) was introduced subsequent to the launch of the energy efficiency labelling standard. CSPF is a measure of the cooling efficiency calculated from total load and total energy consumption per year of operation. Using this method, the energy efficiency of ACs can be evaluated accurately in public facilities such as hospitals, where air conditioning is needed all year round. Accordingly, this project includes the installation of CSPF-supporting Balanced Room-type Calorimeter at Testing and Verifications Centre for Industry/Institute of Energy and Mining Machine (TVCI/IEMM), the sole certification authority in Vietnam where efficiency of ACs will be verified.

In replacing ACs, a prevention plan is required to be prepared and implemented in order to ensure that fluorocarbons used as refrigerants are not released into the atmosphere when they are removed from conventional ACs. In consideration of environment integrity, such Eligibility Criteria have been established through the efforts of Japan and Vietnam, both of which are highly conscious of climate change issues.

NEDO continues its efforts to address global environmental issues through JCM Projects

2.On and After the Project Period

Upon implementing this project, data will be collected and verified from 2015 to 2017. In the meantime, this project will also monitor and verify the amount of CO2 emission reduction under the JCM scheme. Under the energy efficiency labelling standard, which has just launched in Vietnam, the performance of the inverter ACs will be assessed. Together with MOIT, NEDO will continue working towards creating a “green hospital model” and to disseminate the Japanese technology used for this project.
