| Abstract |
As evaluation tools and methods for the Building Energy Efficiency Rating (BEER) are different from those of international green building
certification such as LEED, the performance of the same energy efficient measure for the same building can differ significantly per
certification. This study intends to identify what energy efficiency measures are more advantageous for which building energy performance
certification by evaluating primary energy saving measures that are applied to a real building already certified by BEER and LEED.
Considering that the required insulation and airtightness of a building envelope over the last decade have already been at a high standard,
clients might not be willing to agree to a smaller fenestration ratio. Additionally, the reduction of energy demands by building envelope
measures does not seem to be easily obtainable. Therefore, installing high-efficiency HVAC&R systems and introducing renewable energy
systems would be a more effective strategy for both BEER and LEED. Specifically, efficient HVAC&R systems and PVs are more
advantageous in achieving LEED credits. However, ground source heat pumps and fuel cells have led to less LEED credits, while they are
more advantageous in raising the BEER grade. |
