The building generated 336,824kWh of power during 2 years.
It reduced 143 tons of carbon dioxide and 155 million won of budget during the same period.
The climate change research building of the National Institute of Environmental Research (NIER, President: Kim Sam-cwan) attracts attention as an exemplary facility for mitigating power shortage.
The NIER, a subordinate organization of the Ministry of Environment, said on August 27 that it reduced 143 tons of carbon dioxide and about 155 million won of budget by producing a total of 336,824kWh of power by operating the climate change research building for 2 years from May 2011 to April 2013.
As part of its policy to spread energy self-supporting technologies, the NIER built the three-story climate change research building (1 underground floor and 2 ground floors) with total floor space of 2,500 square meters in April 2011 in the comprehensive environment research complex in Incheon, adopting 66 different technologies for saving and producing energies.
An analysis made by the NIER showed that the climate change research building produced a total of 336,824kWh of power during the two-year period and consumed 329,670kWh of it in the building while supplying 7,155kWh (2.1%) to surrounding buildings.
In the second year, the building generated 174,747kWh of power, an increase of 7.8% (12,670kWh) over the first year when it generated 162,077kWh, and it consumed 8.5% (13,46kWh) more power than the first year, showing surplus of 3,184kWh.
To be specific, the building generated 215,159kWh of power using solar photovoltaic power facilities, and consumed 208,004kWh of it for lighting and operation of office machines in the building, and supplied 7,155kWh to other buildings in the research complex.
And the building also generated 2126kWh and 101,539kWh of power using solar heat and geothermal heat, respectively, and consumed all of such power for heating water, air-conditioning and heating the building.
The NIER analyzed that the climate change research building reduced 143 tons of carbon dioxide, contributing to cutting greenhouse gases, and saved budget of about 155 million won by generating 336,824kWh of power during the past 2 years.
As reduced by the building, 143 tons of carbon dioxide is equivalent to that emitted by a passenger car with engine displacement of 2,000cc when it makes 715 round trips between Seoul and Busan.
And, solar photovoltaic power facilities installed at the building generated the largest amount of power in spring, and Glass-to-Tedlar panels (panel that inserted power generation device between glass and back sheet) provided the highest energy efficiency among solar panels installed at the building.
By seasons, solar photovoltaic power facilities at the building generated more power in the order of spring, autumn, summer and winter, and the building consumed more power in the order of winter, summer, spring and autumn.
Solar photovoltaic power systems generated smaller amount of power in winter due to many snowing days, and the building consumed more power in winter and summer for heating and cooling.
Recognizing its efficiency and value as a zero carbon building, the paper on results of operating the climate change research building is decided to be published in ‘Energy’, a major international scientific journal.
The paper to be published in the international journal will introduce carbon-neutral technologies based on solar photovoltaic power generation facilities.
A director at the NIER said, “It will be a groundbreaking way of reducing damages caused by power failure when technologies applied to the climate change research building are adopted for heavy energy consumption buildings and industrial facilities that represent 53% of the entire power consumption in Korea.”
The NIER plans to work out the ‘Guideline for constructing and operating low-carbon buildings’ by 2014 and actively distribute it.
