Study Report

Note: Preliminary drafts of MRV Methodology and Calculation Sheet are the result of the study. They have neither been officially approved, nor are guaranteed to be officially approved under the JCM/BOCM.
Description of Project/ActivityThe project aims to conduct heating for public buildings (kindergarten, school) in the center of Zuunmod Aimag district through utilizing geothermal heat pump.
Eligibility CriteriaEligibility criteria have been set as follows.
(The methodology is not restricted to geothermal heat pumps, however, explanations in the report are mainly predicated on geothermal heat pumps.)
  • Existing heating water boilers are replaced with hot water heat pumps for heating following project implementation.
  • All the boiler fuel used in existing boilers before project implementation consists of fossil fuel.
  • Existing secondary air conditioning equipment such as radiators, etc. continues to be used without change after project implementation.
  • The separately indicated check list (used for identifying the reference scenario) is passed.
  • The following formula is satisfied: Annual mean COP of heat pumps > Boiler efficiency / Boiler fuel emission factor / 3.6 x Grid emission factor. Moreover, in order to establish this condition, the boiler efficiency, boiler fuel emission factor and grid emission factor are clarified.
  • Indoor heating is conducted.
  • In the case of geothermal heat pumps, soft side support concerning design and execution can be received from advanced countries.
Reference Scenario and Project/Activity BoundaryReference scenario:
Identification was conducted using the checklist. Specifically, the reference scenario refers to the case where current inefficient coal-fired boilers continue to be used.

Boundary:
This encompasses the target heat pump system and the power plants on the grid.
Calculation Method OptionsTwo calculation options have been prepared:
  • Calculation method 1:
    This is selected if any one of the following cases is applicable:
    [1] It is the first project in this climate zone,
    [2] Air source heat pumps are used,
    [3] Water source heat pumps are used,
    [4] A solar system is incorporated into the heat pump system, or
    [5] Electric heaters are incorporated into the heat pump system.
  • Calculation method 2:
    In cases other than the above, calculation method 2 that enables basic monitoring can be selected.
Default Values set in MethodologyThere are no default values set in the methodology, however, if project-specific values are set in the registration stage, the pre-set project specific values that require no monitoring will be as follows:
  • Emission coefficient of boiler fuel
  • Boiler efficiency
  • Heating indoor temperature
  • Standard meteorological data (mean outside temperature)
Monitoring MethodThe main monitoring parameters and monitoring frequency are as follows:
  • Amount of heat supplied by heat pumps (in case of calculation method 1):
      2 times - at the start and completion of monitoring
  • Electric power consumed by heat pumps (in case of calculation method 1):
      2 times - at the start and completion of monitoring
  • Grid emission coefficient:
      1 time – at the completion of monitoring
  • Outside temperature:
      On every hour or a daily set time
  • Conservativeness factor (in case of calculation method 2):
      1 time – at the completion of monitoring
Result of Monitoring ActivityAt kindergartens and school in Zuunmod, monitoring was implemented without a problem based on the Methodology (Ver. 1.0). The monitoring period is as follows:
  • Kindergarten: 47 days from September 15 to October 31, 2012
  • School: 36 days from September 26 to October 31, 2012
GHG Emissions and its ReductionsThe calculated emission reductions are as follows:
  • Kindergarten: 9tCO2
  • School: 14tCO2
Method and Result of VerificationJapan Consulting Institute (Japanese DOE) and BEEC (verification agency in Mongolia) implemented the verification and completed it without any problem. The on-site investigation was implemented from November 27 to 29.
Environmental ImpactsAs the environmental impacts of the project, noise, vibration, leakage of coolant, and changes in the underground thermal environment can be considered, however, these can be kept to a minimum.
Promotion of Japanese TechnologyIt is possible that hard technology (heat pumps and underground heat exchangers) and soft technology (design and execution know-how) will be introduced from Japan.
Sustainable Development in Host CountryFrom the viewpoints of conserving energy, utilizing renewable energy and preventing air pollution, etc., the project activity can make a contribution to sustainable development in the host country.
