premise
we build a lot of stuff we don’t need because of an unquestioned perception of need
consequence
we use a lot of energy we wouldn’t need if we didn’t build the stuff we didn’t need
possibility
we can avoid energy use by not building that stuff...
the study Location: Oahu, Hawaii Building Tenant: US Navy Building Use: Office Building Size: 62,614 GSF (Gross Square Feet)
data collection Study Dates: Mar 19 - May 18 ‘15 Freq. Collect: 24/7 , 7 days/wk

capacity gap
25k GSF latent capacity = GSF to build
225 GSF / PERSON
25k GSF = ~179,000 kWh annually operating energy use for additional GSF
1.85
kWh - Active Hrs
0.60 kWh - Inactive Hrs
25k GSF x ~500kWh per GSF = 12.6mil kWh GSF to build = high
embodied energy cost
134YRS of high performance operations to offset the embodied energy expended in building years to payback energy deficit w/a building
50% more efficient
why this happens
Complexity
Perception
too many buildings, people, projects
actual vs planned, feeling vs fact
not occupied
fully occupied
Room 1 Room 2 Room 3 Room 4 00:00
12:00 while it may feel like...
24:00
not occupied
fully occupied
Room 1 Room 2 Room 3 Room 4 00:00
12:00 while the reality is more likely
24:00
opportunity
by questioning the premise of building in the first place we can avoid unneeded energy use
potentional energy savings
move upstream
Design / Construct / Operate Process
opportunity
instead we can explore changes to operational decisions like density of space, scheduling of space, and other means to mitigate the need for new building, avoiding additional energy use
