The first zero-carbon architecture in Taiwan The Magic School of Green Technology, NCKU

摘要

This paper introduces the design concepts behind the MSGT (Magic School of Green Technology), which is located in the National Cheng Kung University and is the first zero-carbon architecture in Taiwan. Opened on 12 Feb. of 2011, it is a project with the highest energy conservation standards in the world and had been certified as a diamond grade green building by Taiwan’s EEWH system and a platinum grade green building by LEED. The project favors "appropriate technology", " local technology" and "factor-four efficiency" over expensive high technology. Four professors and twelve graduate students conducted numerous experiments and design benefit analyses to eventually achieve a remarkable 65% energy conservation. Specifically, the project applied the most inexpensive and natural devices, such as ceiling fans and a kiln ventilation system, to reduce AC energy consumption for the offices and the international conference hall by 76% and 27%, respectively. Through actual readings from Building Energy Management System (BEMS) during January to December, 2011, accumulated EUI of 40.43 kWh/(m~2.yr) against eQUEST analytical assessment of 43.0 kWh/(m~2.yr) for the same period. Actual energy consumption analysis for air conditioning, lighting, socket outlet, and power equipment, respectively recorded 43.5%, 10.4%, 21.9%, and 24.2% in July. Demonstrating that eQUEST analytical assessed value is very consistent with building’s actual energy consumption readings. The MSGT provides solid proof that the greenest building is achievable through smarter design and better economy.
