Wearable and personal comfort products that will
contribute to an overall energy efficiency strategy
Jason Erwin, Borg & Co
Presented by Paulo Bertoldi
EEDAL ‘17, September 14, 2017
Today’s presentation
•  Challenges
•  Scope and objectives
•  Energy savings and cost effectiveness
•  Next steps
18-02-08 •Cool People, Jason Erwin, Borg & Co, EEDAL ’17 2
Challenge 1: Dramatic and quick
reduction of global AC usage?
Reduce CO2
emissions to zero
by 2050 to reach
1.5°C target
18-02-08 •Cool People, Jason Erwin, Borg & Co, EEDAL ’17 3
Global air cond.
consumption
could increase
10x by 2050
Challenge 2: Traditional EE
measures insufficient
18-02-08 •Cool People, Jason Erwin, Borg & Co, EEDAL ’17 4
AC electric consumption,
despite
–  Minimum energy
standards, labelling and
incentive programs
E.g., US, 1993-2005:
–  28 % eff. improvement
avg. res. AC unit
–  37 % increase avg. home
AC consumption
Challenge 3: Improve thermal
comfort in hotter world?
18-02-08 •Cool People, Jason Erwin, Borg & Co, EEDAL ’17 5
•  41 % of occupants
dissatisfied with indoor
environment (US study)
However, there is hope!
•  Personal environmental
control can greatly extend
comfortable indoor temperatures
Paper objectives: Are wearable
and personal cooling products a
potential solution?
18-02-08 •Title of presentation, version, date, etc 6
•  What are wearable and
personal cooling products?
•  What types of products?
•  At what stage(s) of
development?
•  Is there energy savings
potential?
Scope & Product Types (1/3)
18-02-08 •Cool People, Jason Erwin, Borg & Co, EEDAL ’17 7
•  18 products
identified
–  Cool people directly
through skin contact, or
nearby occupant
–  Primarily indoor
commercial or
residential use
9

Apparel
Jewelry
Comfort
systems
Portable AC
Scope & Product Types (2/3)
18-02-08 •Cool People, Jason Erwin, Borg & Co, EEDAL ’17 8
Wearables Personal comfort/portable
!
Scope & Product Types (3/3)
18-02-08 •Cool People, Jason Erwin, Borg & Co, EEDAL ’17 9
•  5 products in market
•  13 in RD&D phase
•  Active and
passive cooling
mechanisms used
–  E.g., active = battery-
powered fans
–  E.g., passive = fabric
design
!
Apparel examples
Energy savings potential?
18-02-08 •Cool People, Jason Erwin, Borg & Co, EEDAL ’17 10
•  35 % HVAC savings by
expanding set-points
±4°F
•  10 % HVAC savings
per 1°C set-point
expansion
•  50 % HVAC energy
savings with personal
comfort systems
Cost effective?
18-02-08 •Cool People, Jason Erwin, Borg & Co, EEDAL ’17 11
Limited data on price ranges, but
looks promising relative to costs
of new AC!
•  $10-100s wearable or
personal comfort products
vs.
•  $2,000-4,000: per ton of new
cooling installed (home AC)
However…
Wearable and personal
comfort products do not
directly save energy.
They enable savings.
Therefore…
18-02-08 •Title of presentation, version, date, etc 12
Next steps: Demonstration
projects needed!
•  Calling leading EE
organisations!
•  Demonstrations of:
–  Energy savings ranges and
variation?
–  Customer/occupant satisfaction?
–  Durable products?
–  Persistent savings?
–  How cost effective?
18-02-08 •Cool People, Jason Erwin, Borg & Co, EEDAL ’17 13
Thank you!
