What are PCMs?
•
Phase change materials are compounds which melt and solidify at certain
temperatures and in doing so are capable of absorbing, storing and
releasing large amounts of energy. They take advantage of latent heat.
• Water / Ice
• Thermal energy storage

Types of PCM’s
• Paraffin / Waxes
• Salts/ Salt Hydrates
• Fats and Oils

All PCMs must be
contained to be useful
 Macroencapsulation
 Plastic panels, pouches, spheres and pipes
 Metal pipes, tubes and spheres
 Microencapsulation
 Slurry mixture
 Filter cake
 Dry powder

A little math…
 1 gallon of primer contains 0.96 kg mPCMs
 20’ x 12’ x 8’ room has 72 kg air
 mPCM Lf = 180 kJ/kg
 ΔE = m * Lf or (2.88 kg)(180kJ/kg) = 518.4 kJ …using 3
gallons of primer
 ΔT = ΔE / m * Cp, or 518.4 kJ/72 kg * 1 kJ/kg = 7.2°C
 A difference of 7.2°C

A little more math…
 A small window AC unit produces about 5500 Btu per

hour of heat reduction
US Dept. of Energy estimates about 20 Btu’s needed
per square foot of space to be cooled
1 Btu = 1.06 kJoules
The 518.4 kJ of energy storage in the Primer of
previous slide equals about 10% of the total heat
reduction power of the above AC unit
This translates to the equivalent of 6 minutes per
hour of cooling, just due to the passive interaction of
the microPCMs in the Primer

PCM Panel Study
 In 2007/2008 Phase Change Energy Solutions partnered with the Arizona Public Service
(APS) to create an experimental setup to test the performance of PCES’s ENRG Blanket
product. This experiment did not have internal gains from lights/people/equipment so
was effectively an envelope only test.
 For envelope loads only the results of a maximum energy savings of about 30%, a
maximum peak load shift of ~ 60 min, and maximum cost savings of about 30% are quite
impressive. Note: Actual buildings with internal loads may experience larger benefits.
 The study focused on the kWh usage, HVAC run-time and attic temperatures between
the dates of 12/14/2007 and 1/24/08 due to the average temperatures for
the Phoenix Arizona climate. During this period the control building consumed 240
kWh and the BioPCMTM Building consumed 177 kWh Savings, a 26%
reduction. Publications of this experimental setup can be downloaded from these
searches:

 APS Test Temp Regulation
 ASME APS Publication

Tarrytown
500 White Street, Tarrytown, NY
Gross Floor Ft²: 86000
# Floors: 10
Roof/Attic Area: 8600
RETROFIT Suggestions:
Roof Condition (1 thru 10; 1 = needs immediate replacement): 9
NOTE: Roof condition for this project is difficult to determine from satellite images alone. It is suggested that a site visit be conducted to
determine if roof replacement is warranted.
This development would benefit from reroofing with an InfiniteR™ roof system.
Attic retrofit with InfiniteR™ looks problematic as attics appear to be inaccessible for many of the buildings. InfiniteR™ should be installed in all
accessible attic areas
