100% renewables 100% of the time.

Many discussions withing #SummerStudy20 remind me of @NAACP's Centering Equity in the Sustainable Building Sector (CESBS)

Energy efficiency has a central role in improving "zero-energy" buildings
&

consider on-site & off-site sources of renewable energy
#netzero #building
Design strategies can have a large impact, but we need to keep an eye on #energy flows (time*, amount, source, consumption) #energytransition #SummerStudy20

*time can be a multiplier of building loads.

An imperfect thread on some intersections of #BehavioralScience + #ComplexSystems

@DavidPerrott_ @g_arteagoitia
Some ppl recognize behavioral science is in its adolescents in a lot ways. While behavioral scientists have identified design that work really well (you know:
opt-out organ donation @ProfEricJohnson & @dggoldst
Save More for Tomorrow @R_Thaler & @shlomobenartzi)
These are wonderful & we should keep doing these!

But these are only a beginning manifestation of behavioral design & never meant to encompass all of behavioral science

The problem some see is that #nudges are designed in STABLE contexts & with specific demographics

"When making decisions, instead of asking ourselves which option will give us the best results, we should be asking which option will give us good-enough results under the widest range of future states of the world."
psyche.co/ideas/why-effi… via @psyche_the_mag
"And satisficing with an eye toward a radically uncertain future might be called robust satisficing."

Good enough seems to be a better bet - especially as we become familiar with the variability and swift state changes common to #ComplexSystems
So much of #ResilienceTheory has led us to question our #DecisionMaking ; and the hyper-focused drive toward #Efficiency rather than #Resiliency

Market Transformation is difficult for energy!
The Midwest Market Transformation* Collaborative
—Molly Graham @MEEAee
#SummerStudy20 Image
Current problems within market transformations include:
(1) diminishing opportunities for cost-effective #energy savings
(2) there's a need for longer term savings to achieve goals
The Midwest Market Transformation initiative looks to align interests & provide the best regulatory practices given regional policy factors

Whole building system metric needs to be done to improve energy efficiency, but comes with some challenges.

Free software is available to improve whole building analysis, thanks @eeregov !

The burdens of #ClimateChange change are disproportionately placed on people in poverty

@CecilCorbinMark
@aceee #SummerStudy20

Which includes #buildings
For instance, as @CecilCorbinMark, demonstrates this point with:

Air Conditioning during all time high heat waves.

People in poverty may be inequitably burdened by:
Experiencing a heat wave bc their home does not have an air conditioning unit.

Heat waves can cause:
heat exhaustion,
triggering asthma,
organ damage

In elderly populations, this can result in death.

"I say chiller_1, you say chiller_a."

Every building data model is different & unique for building models

#SummerStudy20 @ACEEEdc
There are different ways that technicians describe behaviors - making the communications difficult.

Standard naming conventions? No. More like give a class heirarchy that can be adapted to different sources of equipment.
Unique naming is a human problem, but results from diversity of buildings, retrofits, and management

& can also inhibit optimal Building Information Models (BIMs)
