Wally Walls Recognized As Better
As part of the Energy Star Multifamily High-Rise (MFHR) rating process, subject buildings are required to demonstrate 15% energy cost improvement over a minimally code compliant 'baseline' building with equivalent massing and use. Demonstration of energy performance of the baseline and proposed building is in accordance with the ASHRAE (American Society of Heating Refrigerating, and Air Conditioning Engineers) Standard 90.1-2010 Energy Standard for Buildings Appendix G Performance Rating Method. In states (such as Illinois) that have adopted the 2015 International Code Council International Energy Conservation Code (IECC 2015) the performance target is modified to require 20% improvement over ASHRAE 90.1-2010 baseline.
In addition to establishing that the subject building satisfies the energy performance criteria set forth in Energy Star, it is required to demonstrate that the building is minimally code compliant. In Illinois, such requires demonstrating compliance with the prescriptive or whole building performance paths set forth in either IECC 2015 or (by reference) ASHRAE 90.1-2010 Section 11 Energy Cost Budget Method.
Wally Walls was recently specified for a mid-rise development in Illinois and was determined to exceed the 20% threshold of performance. Wally Walls exceeds MFHR specifications, when used together with LED lighting. While not meeting prescriptive requirements of the Code, it is Wally’s performance that carries the day! Wally Walls and Energy Star - Both Are Better.
