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

Dr. Bing Liu @nwalliance
#SummerStudy20
Total System Performance Ratio (TSPR) evaluates the ENTIRE #HVAC system & can be calculated by:
#BuildingSystems Image
Free software is available to improve whole building analysis, thanks @eeregov !

buildingenergyscore.energy.gov
Pilots of this project and approach indicate:
- reduction of #CO2 & saves #NaturalGas
- easy to use (2 - 10 hrs to finish)
- valuable code-compliance tools
- faster than whole building modeling approach
- rethink system design, useful for interpreting results

#HVAC #ASHRAE
TSPR fills the gap between
Simple & Inexpensive --> Complex & Expensive

TSPR drives down #HVAC energy use & #CO2 emissions

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

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

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

Harry Bergmann @eeregov
#smartcities #smartbuilding
#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)
