The Problem
                     Too much Solar Light Spectrum
                     results in:

                     Infrared
                        Excessive heat results in increased energy
                         consumption, uncomfortable spaces

                     Visible Light
                        Distracting glare, uncomfortable seating

                     Ultra Violet Light

Saving Energy Year Round

eTime Energy completed the installation of the HPS-G transparent window coating in May of
2009 on a Jack Astor’s Restaurant in Toronto, Canada for SIR Corporation. The goal of this
case study was to provide evidence that the installation of the HPS-G coating will directly
cause a decrease in the usage of air-conditioning and heating throughout the summer and
winter months. A careful comparison of hydro and natural gas usages over a 3-year span was
used to determine the impact of the HPS-G coating. Degree-days were used to equate
temperature differences from year to year.

The Installation
The total application process took 4 nights and did not interfere with the operations of this busy
restaurant, as all work was completed afterhours. The non-toxic, water based nature of HPS-G allows
for a safe and healthy installation.

Objective
The objective of this case study is to prove the energy saving capabilities of the HPS-G window coating.
An estimated 20-40% reduction in air conditioning and heating is expected.

The Method of Verification
In order to accurately locate energy savings, eTime uses standard engineering methods of verification
including the degree-day calculation. This formula equates temperatures, eliminating thermostat
variance over the sample period (3 years).

    ∗   Energy savings are calculated by finding the kWh or m3 per degree day (therefore factoring in
        the difference between temperatures of 2009, 2010 and 2011)

    ∗   Example:

            ∗   kWh per degree day in month X ‘Year A =

                      ∗   “kWh for month X ’Year A” divided by “CDD’s (cooling degree days) for month X
                          ‘Year A”

    ∗   A base load of 7,943 m3 (taken from summer gas usage) was used to estimate the gas powered
        equipment except for heating and a cooling base load of 45,000 kWh was used to factor out all
        non AC related electrical equipment

Summary
By reducing the heating and cooling loads by an average of 33%, eTime Energy has benefited this
building both financially and ecologically, resulting in lower energy costs and carbon emissions.
Comfort levels were also increased as costumer and staff complaints were eliminated. The HPS-G
window coating reduced the amount of glare entering the restaurant allowing for a better TV visual
display in the bar area.



Testimonial
“The HPS-G coating has created a much more comfortable environment for both customers
and staff. Our energy use has been reduced dramatically both in the summer and winter
while the reduction in glare allows us to gain the benefit of natural light while running
over ten TV units. The installation was great and we are very happy with this product.”

                                                                  - Mark McLaughlin, General Manager

HPS – G Benefits:
    >   20 – 40% reduction in heating and cooling
    >   Increased comfort levels
    >   Reduced glare
    >   Increased natural lighting
    >   Non-intrusive installation
    >   Reduced UV transmittance


Engineering Support
This case study has been reviewed and verified by JD Hubbert & Associates.

“We have reviewed the calculations and the test results and found that the
savings from the window coating does substantially reduce air conditioning and
heating power needed. Since the orientation of the glass has a considerable effect
on the loads, the savings would be substantial where the glazed areas are large
and facing west or north west.”

                                                        Popularized in the 1980's 'nanotechnology' was
                                                        about building machines such as motors,
                                                       .robot arms, and even whole computers, on the
                                                      scale of molecules just a few nanometers wide, far
                                          smaller than a cell.

                                          As it became an accepted concept, the meaning of the word
                                          shifted to be defined to include anything as large as a whopping
                                          100 nanometers, but they had also had to have novel properties
                                          of course. By comparison, the thinnest of human hairs is
                                          50,000-100,000 nanometers thick ...it should only feel so thick!
                                          But I digress.

                                          So, while HPS HeatShield's 8 micron coating (1/10th of a
                                          human hair) can be considered an iceberg, relatively
                                          speaking, we nonetheless proudly wear the 'nano' badge with
                                          honour, knowing we are the first, the best, and leading our

What Most Window Film Manufacturers Won’t Tell You – And Why

If  you’re  in  the  market  for  window  film,  you  probably  manage  a  building  that’s 
overheating  from  too  much  solar  energy  entering  windows.  According  to  the  California 
Energy Commission, 30% of a structure’s cooling requirements are due to solar energy 
entering through glass. 
It  doesn’t  take  a  rocket  scientist  to  figure  out  that  the  best  place  to  stop  that  heat  and 
reduce  air  conditioning  costs  accordingly,  is  at  the  window.  Given  that  reality,  the 
message to building managers is that window film is primarily for solar heat control. Only 
the  true  uninitiated  think  of  window  film  as  a  product  to  insulate  against  heat  loss  in 
winter,  though  most  solar  heat  control  films  also  provide  a  modest  enhancement  to 
overall building insulation.  
So far, so good. But if you’re a building manager with an overheating problem and think 
the best window film you can buy  is the film that blocks the most heat, you are  on the 
verge  of  making  a  big  mistake,  a  mistake  that  can  cost  you  money.  The  use  of 
conventional  tinted  and  reflective  heat‐blocking  window  films  can  increase  air 
conditioning  and  lighting  costs  and,  in  the  case  of  commercial  properties,  decrease 
employee  productivity  due  to  increased,  not  decreased,  temperatures.  An  additional 
cost from the use of such tinted and reflective conventional films is the change they cause 
in  the  external  appearance  of  windows  which  can  have  a  negative  impact  on  property 
values. 
All this from a heat‐blocking window film? Absolutely, but how? 
While most window film manufacturers talk about their tinted and reflective films’ ability 
to block heat, they seldom confess that their films also block light. In some cases, highly 
reflective  window  films  with  metalized  heat‐reflective  coatings  also  block  as  much  as 
85% of the visible light outside from entering the inside of a building.  
Yes,  many  conventional  tinted  and  reflective  window  films  do  successfully  block 
unwanted  solar  energy,  (though  a  surprising  number  aren’t  so  great  at  that  either),  but 
because  they  also  block  desirable  visible  light,  the  result  is  a  building  in  which  natural 
levels  of  light  are  permanently  excluded.  In  addition,  conventional  window  films  lessen 
the transparency and change the appearance (often by adding color) to existing glass. In 
commercial  properties  especially,  the  consequent  darkened  interiors  require  increased 
lighting which not only adds cost but as a generator of heat, often results  in  more,  not 
less, use of air conditioning, defeating the cost‐saving benefit of applied window film in 
the first place. 




                       http://chiefengineer.org/?p=1586#comment-4995
Experience  suggests  that  employees  spending  eight  or  more  hours  in  unnaturally  dark 
spaces  feel  less  energized,  often  suffer  more  illness,  take  more  sick  days  and  are  less 
productive than their counterparts in naturally illuminated environments. 
What’s a building manager to do?  
Obviously, we could eliminate the problem of solar overheating, as well as better insulate 
buildings,  if  we  got  rid  of  windows  entirely.  Think  of  how  much  less  costly  structures 
would be to build and operate if the amount of external glass was significantly reduced or 
eliminated.  
Before you wonder what such buildings might be like, the evidence is already in from the 
experience  of  building  and  using  windowless  schools  and  other  structures  constructed 
during the first great energy crisis of the 1970s. To put it bluntly, building occupants did 
not like working with few or no windows. Student’s grades decreased and their attitudes 
were less than positive.  
It  is  important  to  note  why  people  like  windows.  Few  of  us  are  lucky  enough  to  have 
great  views  of  the  ocean  or  mountains  through  our  windows  but  all  of  us  appreciate, 
desire (and need) natural light as the primary source of internal illumination.  
What does that leave us? On the one hand, building occupants desire and need windows 
for  all  important  natural  light  and  a  connection  with  the  outside  environment;  on  the 
other hand, even a small amount of glass on the south or west side of a building can result 
in uncomfortable overheating and increased air conditioning and other costs.  
If many conventional tinted and reflective window films can successfully block undesirable 
heat,  why  can’t  they  simultaneously  transmit  desirable  levels  of  light?  Well,  from  the 
point of view of a window film manufacturer, that’s the tricky part of making window film. 
While it is relatively easy to make tinted and reflective film that blocks heat, it is another 
thing  entirely  to  produce  what  is  called  spectrally  selective  window  film,  capable  of 
blocking undesirable heat while simultaneously transmitting desirable light. 
The  good  news  is  that  at  least  one  spectrally  selective  window  film  is  available  and  for 
years has been successfully installed on windows and fixed glass in commercial properties. 
The  bad  news  for  building  managers  in  the  market  for  window  film,  is  that  several 
manufacturers call their film spectrally selective when it is only marginally so. 
The  definitive  test  is,  how  much  visible  light  does  a  film  transmit?  The  ideal 
film  would  be  totally  clear  yet  able  to  significantly  block  unwanted  solar  heat 
and  reduce  glare.  A  true  spectrally  selective  film  (coating)  transmits  at  least  70%  of 
visible  light.  Most  calling  themselves  spectrally  selective  actually  transmit 
no more than 58%. Such films when installed on a window become visible to the naked 



                      http://chiefengineer.org/?p=1586#comment-4995
eye.  If  a  window  film  looks  tinted  and  not  clear  it  is  not  optimally  selective  in  the  all‐
important category of visible light transmission.  
When faced with a choice between a tinted or reflective film that blocks more heat and a 
spectrally selective film that blocks less heat but transmits more light, the smart money is 
on the spectrally selective film (coatings).  
Case  in  point,  the  Los  Angeles  Department  of  Water  and  Power’s  (LADWP)  rebate 
program  for  window  film  is  based  on  a  film’s  luminous  efficiency  constant,  which  is  a 
measurement of its ability to simultaneously block heat and transmit light. While a very 
reflective film that blocks more heat than a spectrally selective film earns a 55 cent per 
square foot rebate from LADWP, a spectrally selective film that blocks less heat but lets 
in  more  light  receives  a  higher  rebate  of  85  cents  per  square  foot.  Only  spectrally 
selective  films  with  luminous  efficiency  over  1.0  receive  the  higher  rebate.  (See  table)

Less expensive conventional window films have a shorter payback compared to more 
expensive spectrally selective films. However, when you add on the cost of extra 
energy used for lighting and air conditioning operation due to conventional films 
inability to transmit sufficient visible light, the payback for conventional film and 
spectrally selective film becomes comparable.  
Given rising electricity and natural gas rates, the rate of payback for spectrally selective 
film is always improving – averaging about four years. Factor in the issues of occupant 
morale, employee productivity and building appearance and it’s clear that spectrally 
selective window film is the preferred choice.

UPDATE BY ETIME ENERGY 
The article above is factual and accurate in its discussion of FILM coatings. These 
coatings, while the ‘go‐to’ solution until now, have drawbacks beyond what was 
mentioned above. They also have wear issues, visual concerns such as optical distortion, 
and can be considered a fire hazard, among other concerns.  
The article above was written without the working knowledge of ground breaking 
LIQUID NANO technologies that are upon us – and available to you – at this very 
moment.  
Please take an additional moment to update yourself on an amazing solar heat gain 
solution by ETime Energy Inc. 

                                                                                               
As the article above notes, LADWP offers a higher rebate for spectrally selective film 
EVEN THOUGH it blocks less solar heat. In large part because it allows more visible light 
through, which from a ‘comfort’ perspective, is highly desirable. 
Imagine for a moment a product that works on the entire solar spectrum. A spectrally 
selective product that allows over 70% visibility, blocks radiant heat more effectively 
than any film with the same Tv rating, and, blocks up to 99.7% UV rays. 
Imagine again this product being used in a retrofit application, on any glass or 
polycarbonate surface for ANY window or door application… a Green product that 
reduces the need for replacing windows, and reduces landfill use. 
Imagine further this product being applied in a non‐evasive manner, after‐hours or 
your schedules convenience. 
Finally, just imagine yourself sitting back, taking in the view that you were meant to see, 
with plenty of light, no visible distortion, and with reduced interior glare – all while 
being more comfortable than you have been for years – year round. And let’s not forget 
the 20‐40% heating and cooling energy savings, and reduced HVAC wear and tear. 
This reality can all be achieved NOW with ETime Energy’s HPS HeatShield nano coatings 
– a ground breaking, certified and field approved technology.  
HPS HeatShield has the lowest cost base per visible light transfer for the radiant heat it 
blocks than any other window coating product available on the market today

  • 25. eTime Energy Saving Energy Year Round eTime Energy completed the installation of the HPS-G transparent window coating in May of 2009 on a Jack Astor’s Restaurant in Toronto, Canada for SIR Corporation. The goal of this case study was to provide evidence that the installation of the HPS-G coating will directly cause a decrease in the usage of air-conditioning and heating throughout the summer and winter months. A careful comparison of hydro and natural gas usages over a 3-year span was used to determine the impact of the HPS-G coating. Degree-days were used to equate temperature differences from year to year. The Installation The total application process took 4 nights and did not interfere with the operations of this busy restaurant, as all work was completed afterhours. The non-toxic, water based nature of HPS-G allows for a safe and healthy installation. Objective The objective of this case study is to prove the energy saving capabilities of the HPS-G window coating. An estimated 20-40% reduction in air conditioning and heating is expected. The Method of Verification In order to accurately locate energy savings, eTime uses standard engineering methods of verification including the degree-day calculation. This formula equates temperatures, eliminating thermostat variance over the sample period (3 years). ∗ Energy savings are calculated by finding the kWh or m3 per degree day (therefore factoring in the difference between temperatures of 2009, 2010 and 2011) ∗ Example: ∗ kWh per degree day in month X ‘Year A = ∗ “kWh for month X ’Year A” divided by “CDD’s (cooling degree days) for month X ‘Year A” ∗ A base load of 7,943 m3 (taken from summer gas usage) was used to estimate the gas powered equipment except for heating and a cooling base load of 45,000 kWh was used to factor out all non AC related electrical equipment www.etimeenergy.com 2

  • 27. eTime Energy Summary By reducing the heating and cooling loads by an average of 33%, eTime Energy has benefited this building both financially and ecologically, resulting in lower energy costs and carbon emissions. Comfort levels were also increased as costumer and staff complaints were eliminated. The HPS-G window coating reduced the amount of glare entering the restaurant allowing for a better TV visual display in the bar area. Testimonial “The HPS-G coating has created a much more comfortable environment for both customers and staff. Our energy use has been reduced dramatically both in the summer and winter while the reduction in glare allows us to gain the benefit of natural light while running over ten TV units. The installation was great and we are very happy with this product.” - Mark McLaughlin, General Manager HPS – G Benefits: > 20 – 40% reduction in heating and cooling > Increased comfort levels > Reduced glare > Increased natural lighting > Non-intrusive installation > Reduced UV transmittance Engineering Support This case study has been reviewed and verified by JD Hubbert & Associates. “We have reviewed the calculations and the test results and found that the savings from the window coating does substantially reduce air conditioning and heating power needed. Since the orientation of the glass has a considerable effect on the loads, the savings would be substantial where the glazed areas are large and facing west or north west.” www.etimeenergy.com 4

Popularized in the 1980's 'nanotechnology' was about building machines such as motors, .robot arms, and even whole computers, on the scale of molecules just a few nanometers wide, far smaller than a cell. As it became an accepted concept, the meaning of the word shifted to be defined to include anything as large as a whopping 100 nanometers, but they had also had to have novel properties of course. By comparison, the thinnest of human hairs is 50,000-100,000 nanometers thick ...it should only feel so thick! But I digress. So, while HPS HeatShield's 8 micron coating (1/10th of a human hair) can be considered an iceberg, relatively speaking, we nonetheless proudly wear the 'nano' badge with honour, knowing we are the first, the best, and leading our nanocoatings class! eTIPS "Look, on the window!

  • 31. What Most Window Film Manufacturers Won’t Tell You – And Why If  you’re  in  the  market  for  window  film,  you  probably  manage  a  building  that’s  overheating  from  too  much  solar  energy  entering  windows.  According  to  the  California  Energy Commission, 30% of a structure’s cooling requirements are due to solar energy  entering through glass.  It  doesn’t  take  a  rocket  scientist  to  figure  out  that  the  best  place  to  stop  that  heat  and  reduce  air  conditioning  costs  accordingly,  is  at  the  window.  Given  that  reality,  the  message to building managers is that window film is primarily for solar heat control. Only  the  true  uninitiated  think  of  window  film  as  a  product  to  insulate  against  heat  loss  in  winter,  though  most  solar  heat  control  films  also  provide  a  modest  enhancement  to  overall building insulation.   So far, so good. But if you’re a building manager with an overheating problem and think  the best window film you can buy  is the film that blocks the most heat, you are  on the  verge  of  making  a  big  mistake,  a  mistake  that  can  cost  you  money.  The  use  of  conventional  tinted  and  reflective  heat‐blocking  window  films  can  increase  air  conditioning  and  lighting  costs  and,  in  the  case  of  commercial  properties,  decrease  employee  productivity  due  to  increased,  not  decreased,  temperatures.  An  additional  cost from the use of such tinted and reflective conventional films is the change they cause  in  the  external  appearance  of  windows  which  can  have  a  negative  impact  on  property  values.  All this from a heat‐blocking window film? Absolutely, but how?  While most window film manufacturers talk about their tinted and reflective films’ ability  to block heat, they seldom confess that their films also block light. In some cases, highly  reflective  window  films  with  metalized  heat‐reflective  coatings  also  block  as  much  as  85% of the visible light outside from entering the inside of a building.   Yes,  many  conventional  tinted  and  reflective  window  films  do  successfully  block  unwanted  solar  energy,  (though  a  surprising  number  aren’t  so  great  at  that  either),  but  because  they  also  block  desirable  visible  light,  the  result  is  a  building  in  which  natural  levels  of  light  are  permanently  excluded.  In  addition,  conventional  window  films  lessen  the transparency and change the appearance (often by adding color) to existing glass. In  commercial  properties  especially,  the  consequent  darkened  interiors  require  increased  lighting which not only adds cost but as a generator of heat, often results  in  more,  not  less, use of air conditioning, defeating the cost‐saving benefit of applied window film in  the first place.  http://chiefengineer.org/?p=1586#comment-4995
  • 32. Experience  suggests  that  employees  spending  eight  or  more  hours  in  unnaturally  dark  spaces  feel  less  energized,  often  suffer  more  illness,  take  more  sick  days  and  are  less  productive than their counterparts in naturally illuminated environments.  What’s a building manager to do?   Obviously, we could eliminate the problem of solar overheating, as well as better insulate  buildings,  if  we  got  rid  of  windows  entirely.  Think  of  how  much  less  costly  structures  would be to build and operate if the amount of external glass was significantly reduced or  eliminated.   Before you wonder what such buildings might be like, the evidence is already in from the  experience  of  building  and  using  windowless  schools  and  other  structures  constructed  during the first great energy crisis of the 1970s. To put it bluntly, building occupants did  not like working with few or no windows. Student’s grades decreased and their attitudes  were less than positive.   It  is  important  to  note  why  people  like  windows.  Few  of  us  are  lucky  enough  to  have  great  views  of  the  ocean  or  mountains  through  our  windows  but  all  of  us  appreciate,  desire (and need) natural light as the primary source of internal illumination.   What does that leave us? On the one hand, building occupants desire and need windows  for  all  important  natural  light  and  a  connection  with  the  outside  environment;  on  the  other hand, even a small amount of glass on the south or west side of a building can result  in uncomfortable overheating and increased air conditioning and other costs.   If many conventional tinted and reflective window films can successfully block undesirable  heat,  why  can’t  they  simultaneously  transmit  desirable  levels  of  light?  Well,  from  the  point of view of a window film manufacturer, that’s the tricky part of making window film.  While it is relatively easy to make tinted and reflective film that blocks heat, it is another  thing  entirely  to  produce  what  is  called  spectrally  selective  window  film,  capable  of  blocking undesirable heat while simultaneously transmitting desirable light.  The  good  news  is  that  at  least  one  spectrally  selective  window  film  is  available  and  for  years has been successfully installed on windows and fixed glass in commercial properties.  The  bad  news  for  building  managers  in  the  market  for  window  film,  is  that  several  manufacturers call their film spectrally selective when it is only marginally so.  The  definitive  test  is,  how  much  visible  light  does  a  film  transmit?  The  ideal  film  would  be  totally  clear  yet  able  to  significantly  block  unwanted  solar  heat  and  reduce  glare.  A  true  spectrally  selective  film  (coating)  transmits  at  least  70%  of  visible  light.  Most  calling  themselves  spectrally  selective  actually  transmit  no more than 58%. Such films when installed on a window become visible to the naked  http://chiefengineer.org/?p=1586#comment-4995
