Building Decarbonization Coalition Webinar Series Presents: Residential Building Electrification Cost-effectiveness With Amber Mahone of Energy and Environmental Economics, Inc. (E3) - Shared screen with speaker view
Did you look at the effect of doing demand response or running the HPWH's on timers?
How do the economics change when electrication is paired with PV, which presumably could power the appliances with cheaper electricity than grid-purchased.
Did you look at the effect of coupling these with PV and battery storage?
On the grid impcts slide you look at the impat of the canging climate on cooling demand?
When looking at the GHG emissions associated with refrigerants and fugitive NG, you neglect to even mention that these GHG’s are orders of magnitude more effective than CO2 at trapping heat.
Did you analyze the thermal storage aspect of the HPWH and how does that help decarbonize?
Did you consider hydronic heat pump systems, one heap pump with water storage tank providing both water heating and ducted space heating?
Have you explored new lower voltage (110 V) and lower current (15 amps) HPWH's to reduce panel and wiring upgrade costs?
FO THE mf BLD EXAMPLS, DID YOU +
How can I access the cost assumptions on HP heating and water heating compared to gas?
For the MF bldg examples, did you look at central water heating systems as well as individual WHs?
What impact would EE retrofits / natural stock turnover have on the 1990s vintage homes - that might deviate from 1990 T24 specs?
REALLY NICE JOB Amber & Team!
Thank you for organizing!
Thank you so much! Can't wait for the next studies to focus on non-res sectors!!!
