Lawrence Berkeley National Laboratories (LBNL)
Glass is Spectrally Selective when:

 Spectrally Selective Tinted Glass
60% (VLT) ÷ 0.40 (SHGC) = 1.50 (LSG)
Examples (Non-Spectrally Selective Glass)
 Pyrolytic Low-E (Passive Low-E) Coated Glass

32. Low-E Coatings Role in
Energy Efficient Glazing
• Most buildings in the country are not clad with the most efficient
glass available.
• There are approximately 77.2 billion square feet of built
environment in the U.S.
• This figure is expected to climb by another 7 billion square feet (an
additional 536,000 buildings) in the next five years.
• If this new development incorporates the most efficient glass
technology available, significant upfront and long-term savings will
result.

33. Low-E Coatings Role in
Energy Efficient Glazing
• If all existing buildings and new construction were to use the latest
glazing advancement – triple-silver Low-E glass – 2,134 trillion
BTU’s would be saved annually.
– This is 2% of the total US energy consumption
per year.
– This would save $38 Billion (gas and electric)
per year.
– CO2 emissions would be reduced by 123
million tons/year.
While that is the best-case scenario, the impact triple-silver Low-E
glass can have on energy consumption, economic savings and the
environment is vast.

44. Low-E Coatings Role in

The Simulation Model
• DOE 2.2
– Calculates hour-by-hour energy consumption of the prototype facility
over an entire year (8,760 hours)
– Uses hourly climate data for any location
– Detailed input provides accurate simulation of building features such as
shading, fenestration, interior building mass, envelope building mass,
and dynamic response of heating and air conditioning systems.

45. Low-E Coatings Role in
Energy Efficient Glazing
The Simulation Model
• DOE 2.2 energy simulations were developed for each glazing scenario
according to their unique characteristics
• The model ran a simulation for both building types, in all 12 locations, and
for both architectural scenarios (punched windows and window walls)
• The model calculated the effect of each glazing based on the following:
– Building loads
– Cooling equipment size
– Building energy costs
– HVAC Cooling costs
• based on cooling size in tons and total air supply flow into the
building

46. Low-E Coatings Role in
Energy Efficient Glazing
The Simulation Model
• Calculating HVAC capital cooling costs
– Calculations were based on peak cooling loads, in tons, for total air
supply into the building.
– Cooling costs were estimated at $1,200 per ton.
– HVAC equipment costs were estimated at $3.50 per cfm airflow.
• Utility rate calculations
– Utility companies for each of the 12 cities provided the latest rate tariffs
for electricity and natural gas.

47. Low-E Coatings Role in
Energy Efficient Glazing
The Simulation Model
• Calculating carbon emissions
– Derived using Carbon Dioxide Emissions for the Generation of Electric
Power in the United States, a report published in 2000 by the U.S.
Department of Energy.
*Estimates were used to simplify the model and meta calculations.

52. Low-E Coatings Role in
Energy Efficient Glazing
2nd vs. 3rd Surface
“The general recommendation from the glass industry
for commercial buildings is to leave the choice (coating
on either #2 or #3 surface) to the glass manufacturer.”
(Source: MasterSpec Evaluation Section, Coated Glass.)
“For most commercial buildings, regardless of climate,
in which the primary concern is reducing the solar heat
gain, the location (coated surface) is of less concern,
and placing it on either the second or third surface
should remain an option.”

53. Low-E Coatings Role in
Energy Efficient Glazing
2nd vs. 3rd Surface
 Coatings can be applied to the #2 or #3 surface of an
insulating glass unit (IGU)
 Having the flexibility to coat either the #2 or # 3
surface of an IGU allows for more competitive pricing
without dramatically impacting its solar control
performance
 In some cases, (such as a tinted outdoor lite and a
clear indoor lite) applying coatings to the #3 surface
instead of the #2 surface permits accelerated product
delivery
