Why so much interest in Cool Roofs ?
COOL ROOFS EQUATE TO BIG BENEFITS
TO THE BUILDING OWNER AND THE
ENVIRONMENT
5. EPOX-Z NRG USER BENEFITSEPOX-Z NRG USER BENEFITS
Improved Comfort because the building’s interior is subject to
less thermal flux and stays cooler during the warm season
Reduced Energy Costs because of reduced air-conditioning
Longer AC unit life resulting from decreased air-conditioning
loads
Increased Roof Longevity due to reduced thermal flux of the
roof
6. EPOX-Z NRG ENVIRONMENTAL BENEFITSEPOX-Z NRG ENVIRONMENTAL BENEFITS
Cool roofs are distinguished among energy conservation measures because
of the many environmental benefits they can provide. This is attributed to
the fact that they combat the urban heat island effect
The urban heat island effect is a phenomenon that is characterized by a
measured increase in the ambient air temperature in cities over their
surrounding rural areas. This is due to roofs and other non-reflective
surfaces that absorb and trap solar radiation — or heat
The excess trapped heat is gradually released to the ambient air throughout
the day, evening and nighttime hours, warming up the urban core round
the clock. The effect results in an environmentally negative and spiraling
impact, including:

Increased demand for air-conditioning in both air-conditioned
and un-conditioned buildings, thus increasing the potential
for the installation of air-conditioners in buildings that
currently don’t need them
Increased greenhouse gas emissions that contribute to global
warming, released as a result of fossil fuel generated
electricity to power air conditioners
Increased smog formation.
9. EPOX-Z NRG – HOW IT WORKSEPOX-Z NRG – HOW IT WORKS
Two thermal properties that characterize cool roofs are solar
reflectance and thermal emittance
A cool roof minimizes the solar heat gain of a building by first
reflecting incoming radiation and then by quickly re-emitting
the remaining absorbed portion
As a result, the cool roof stays cooler than a traditional roof
of similar construction

Have you defined your requirements for your cool roof
projects?
The Basic Questions to Ask
• Does this Cool Roof Coating meet the DOE Requirements?
• What is its weatherability/durability?
• What is the testing data?

PERFORMANCE CHARACTERISTICSPERFORMANCE CHARACTERISTICS
To be effective any cool roof coating must first act as a barrier to prevent
chemicals and moisture from reaching the roof surface
In general, the more permeable a coating is to the passage of moisture as is
typical of many water-reducible coatings, the greater its affinity for water
and the greater the increase in transmission when tested in and exposed
to high humidities …ASTM D 1653
Performance characteristics of coatings can be evaluated by laboratory
protocol
Specifically ASTMD 1653 for Permeability, ASTM D 714 for blistering and
ASTM D 4214 for degradation or chalking
13. EPOX-Z NRGEPOX-Z NRG
PERFORMANCE CHARACTERISTICSPERFORMANCE CHARACTERISTICS
ASTM D 714:Resistance to chemical or water penetration. Ratings are 1-10
with10 representing no visible signs of blistering which is the highest/best
rating
ASTM D 659 with the standard having four ratings: No. 2 (severe chalking),
No. 4 (moderate to severe chalking), No. 6 (moderate chalking), and No. 8
(light chalking).
ASTM D 1653 Permeability Coatings with ratings <1 are considered
impermiable

• The average pH of rainfall in New York State
ranges from 4.0 to 4.5, which is up to 30 times
more acidic than "normal."
• Acid deposition also damages building
materials by eroding the ornamental facades,
statuary and other vulnerable edifices that are
an important part of our heritage.
16. EPOX-Z NRG – ISSUES TO AVOIDEPOX-Z NRG – ISSUES TO AVOID
THE MAJORITY OF COATINGS USE WATER OR VOC LADEN SOLVENTS AS THE
VEHICLE TO MAINTAIN THE COATING IN A LIQUID STATE SO THAT IT CAN
BE TRANSFERRED FROM THE CONTAINER TO THE SURFACE.THE DRYING
PROCESS RELIES ON SOLVENT OR WATER EVAPORATION
VOC’S ARE HARMFUL TO THE ENVIRONMENT AND ARE ALSO
DETRIMENTAL TO THE COATING’S PERFORMANCE.
THESE COATINGS MAY NOT BE ABLE TO ALLOW THE SOLVENTS OR WATER
TO FULLY EVAPORATE RESULTING IN BLISTERS,VOIDS, PINHOLES OR SOFT
SPOTS IN THE COATING
17. FAILURES TO AVOIDFAILURES TO AVOID
While coating failures may occur for number of
reasons, they can generally be categorized into
three main groupings:
1.Coating manufacturer related or caused
2.Owner/specifier related or caused
3.Coating applicator related or caused

The majority of coatings use water or voc laden solvents as the vehicle to maintain the coating in a liquid state so that it can be transferred from the container to the surface. The drying process relies on solvent or water evaporation VOC’s are harmful to the environment and are also detrimental to the coating’s performance. These coatings may not be able to allow the solvents or water to fully evaporate resulting in blisters,voids, pinholes or soft spots in the coating
While coating failures may occur for number of reasons, they can generally be categorized into four main groupings: 1.Coating manufacturer related or caused 2.Owner/specifier related or caused 3.Coating applicator related or caused 4.Environmental service related or caused.
