Heat Source System Renovation of a Large Complex Building introducing Commissioning

Heat Source System Renovation of a Large Complex Building introducing Commissioning

Seminar Abstract 

Kyoto Station is a large-scale and complex building, which consumed more
primary energy than any other in the Environmental Model City of Kyoto, Japan.
To overcome the disparity, a commissioning process was introduced in the
heat-source plant renovation project, targeting a 60% energy reduction. The
success of the enormous reduction is attributed to applying an HVAC system
simulation tool to analyze and evaluate the performance of proposed
heat-source systems in the design phase and optimize the operation of chillers
with different performance characteristics and a heat-recovery heat pump
during the functional performance testing phase in commissioning.

Seminar Speaker(s) 

Harunori Yoshida, Ph.D
Chairman of NPO Building Services Commissioning Association (BSCA)/ Professor Emeritus at Kyoto University, NPO Building Services Commissioning Association (BSCA)

Professor Harunori Yoshida has made contributions in the field of applications of building simulation on research projects of significant scope especially in energy conservation of HVAC systems. He developed many new simulation based methodologies, such as automatic fault detection of air distribution systems, air-conditioning load prediction used for thermal storage tank operation, total optimization of a heat source system, etc. His interest is mainly in existing building energy conservation rather than newly constructed buildings because the energy conservation of tremendous building stock is the key issue at present. He has also made fundamental contribution in the field of building science mainly related to air-conditioning load calculation. He invented very unique computational approach in most of his work. For these contributions he received many awards from the academy in Japan. Now he is leading NPO organization, Building Services Commissioning Association, as the chairman to promote energy conservation in Japan.
