Californias Energy Crisis

• Utilities barely able to maintain energy demands
• Cal ISO
• Blackouts occur when operating reserves fall
  below 1.5
• Blackouts begin at stage 3 emergency level

3
Californias Blackouts Statistics 2001 Crisis

• Happened twice in year 2001
• 675,000 homes without power in N. California
• 500,000 homes without power in California
• Temperatures 87F
• Source CNN

4
Problems

• Temperatures exceed 90F
• Property homeowners use AC to cool down
• Massive combined use overloaded the system
• System collapses
• Rolling blackouts
• Other Variables
• Low water levels
• Power companies deregulated
• No new power plants being built

Environmental Impact Related To Heat

• Increased Urban Pollution
• SMOG
• created by photochemical reaction of pollutant
• in air due to heat
• Ozone depletion
• HAPS
• all accelerated by heat
• Green House emissions
• Air advisory alerts
• need to burn more fossil fuels to generate
  electricity, therefore more pollution
• Urban Heat Island Effect
• Releases Carcinogenic Fumes

The Vicious Cycle of Heat
HOT DAY
INCREASED USE OF AIR CONDITIONING
SYSTEM CRASH
OVERLOADING THE UTILITIES
THE VICIOUS CYCLE OF HEAT
ENERGY LEVELS DIP BELOW 1.5
BURNING MORE FOSSIL FUELS TO SUPPLY ENERGY
HIGHER RELIANCE ON FOREING FUEL IMPORTS
EMMISION OF CO2, NO2, SO2
ATMOSPHERE IS POLLUTED AND LEADS TO SMOG, OZONE
DEPLETION, AND GREEN HOUSE EFFECT
ELECTRICITY GETS MORE EXPENSIVE

Health Effects - Air Quality Index

• Air Quality Index
• 0-50
• 51-100
• 101-150
• 151-200
• 201-250
• 251-300

• Everything above 100
• is considered a
• public health problem. Four of the ten worst air
  quality cites in the USA are in California.

10
Cost Effective Solution

• Lower the ambient temperature within the
  building envelope
• Lower the demand for cooling systems
• Lower propensity for SMOG and OZONE depletion

• How do we achieve this ?

11
By Stopping Heat Ingress Before It
Penetrates The Substrate !

• Roofs
• Exterior walls, especially West and East
• Pavements

North
By applying a permanent exterior radiant barrier
that encapsulates the building envelope you
reduce heat ingress, lower SMOG and OZONE
depletion, and save on electrical costs.

Federal Industry Initiatives

• Federal
• (proactive measures)
• Title 24 for commercial roofs
• Amendment in years 2005 and 2010
• No law for exterior coatings, only interior
  radiant barriers
• No law for stucco
• LBNL
• University of California Berkeley
• ORNL/DOE

• Industry
• (reactive measures)
• Electric solar vents
• Interior radiant wall barriers
• Interior radiant roof barriers
• Air conditioning
• Solar Panels
• Insulation Foam

13
Proactive Approach Stop the heat before it
enters home!

• By covering the entire house with heat reflective
  coating like Thermoshield,
• we can eliminate
• Solar vents solar panels
• Interior radiant barriers
• Roof radiant barriers
• Insulation foam in the roof deck
• and reduce need for ...
• Energy efficient windows
• Air conditioning
• Insulation

The Science of Heat Reflective Coatings

• The Suns Energy
• 57 thermal emittance
• 40 solar reflectance
• 3 UV
