Some Accolades“Since the install July 1st we have been able to leave the blinds up all day and let light into the rest of the restaurant.Previously, clients were hesitant to sit near the window due to the glare and the heat in the area. They currently ask to be seated up front. The staff have remarked that it is more comfortable working at this station. This seating area represents 32 seats.”Mike McCarthy, Cora Queensway

“The installation was completed after hours, was non intrusive, and did not disrupt normal office operations. Congratulations to the eTime installation team. Further, after coating was completed, comfort levels have increased for those using the meeting room during hot sunny days.”Gavin Maher, MES, LEED ®AP, Ontario Realty Corporation

“Complaints have stopped coming in from the school, and everyone there is happy with the installation and product effect.”Agnese De Fazio, Project Supervisor, Hamilton-WentworthDistrict School Board

“One month ago eTime Energy installed their HPS HeatShield transparent glass coating onto our south facing windows. Typically the blinds were always down on these windows because heat transfer and glare was a problem for those working near the windows. After the windows were coated staff were able to raise blinds and enjoy the outside view because the coating reduced heat transfer and glare into the offices. We are happy with the benefits provided by the coating.”Peter Pesce, Reunion Island

“If not for fact that I personally witnessed the heat shielding properties of the HPS coating first hand, I would have been skeptical in reading any claim stating that 20 – 40% heating and cooling energy savings could be achieved using this product. But our test data clearly shows that this is indeed thecase as evidenced during the hot and humid days of late summer when the HPS treated glass surfaces reduced the inside temperature of the test box by an average of 12°C. This alone translates into a 35% reduction in the amount of cooling energy that would have otherwise been required if the glass was not coated.”Leo Salemi, Professor, Centre for Construction and Engineering Technologies, George Brown College

eTime Energy – Energy Saving Case Study

www.etimeenergy.com 2

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

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.”

Dear Ray,

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 a leading energy commission, 30% of a structure's cooling requirements are due to solar energy entering through glass. But the use of conventional tinted and reflective heat-blocking window films can actually increase air conditioning and lighting costs and, in the case of commercial properties, decrease employee productivity due to increased, not decreased, temperatures. >>> Review Chief Engineer report

Did You Know?

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!

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. 

Page 32: HPS Product Prospectus: A NextGen nanotech liquid window coating providing unheard of energy savings!

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

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) 

 

Type of glass or applied film

% of daylight through glass

% of solar energy through glass

Shading coefficient*

Luminous efficacy constant**

% of visible light reflectance interior/exterior

1/4" clear glass 89 77 0.96 0.93 7 / 7 1/4" clear glass with tinted film 37 64 0.74 0.50 6 / 6 1/4" clear glass with reflective film 37 44 0.51 0.73 18 / 28  

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
