Debate 1 (Intermediate)
Does Building Energy Efficiency Matter in a 100% Renewable Grid?
Track: High Efficiency Design and Operation
Room: Orlando VI
Chair: Jim Edelson, Associate Member1, Randall Higa, P.E., Member2, Adam Hinge, P.E., Fellow ASHRAE3, Jon McHugh, P.E.,
Member4 and Mark Lyles1, (1)New Buildings Institute, Portland, OR(2)Southern California Edison, Rosemead, CA(3)Sustainable
Energy Partnerships, Tarrytown, NY(4)McHugh Energy Consultants Inc., Fair Oaks, CA
Hundreds of jurisdictions across North America - cities, states, and provinces - have pledged to achieve 100% renewable grid-
based electricity between 2030 and 2050. As emerging policies move buildings from mixed-fuel to all-electric, a new dynamic
arises where building energy consumption becomes all-renewable and carbon impacts of building energy consumption are
diminished or eliminated. Does efficiency remain relevant when the electric grid becomes carbon-free? Is time-of-use demand
more important than overall consumption? How do behind-the-meter storage and renewables compare to efficiency? This debate
will present arguments that traditional efficiency is or is not still critical when electricity (or gas) is carbon-free.

Room: Orlando VI
Sponsor: 2.8 Building Environmental Impacts and Sustainability
Chair: Janice Means, P.E., Life Member, Lawrence Technological University, Southfield, MI
When designing or retrofitting buildings for increased energy efficiency and high performance, take care to not cause unforeseen
and unintentionally detrimental issues for occupants or the building. Occupants may be adversely affected by decreased indoor
environmental quality and water quality if green design is not carefully thought out and executed. Interior materials, furnishings
or the building envelope itself can be compromised if energy conservation measures are not fully analyzed for potential effects.
Speakers address potentially adverse issues affecting IAQ, acoustics, water-quality and the building (with potential solutions)
when designing/retrofitting for energy efficiency and high performance.
