    • eTime Energy – Energy Saving Case Study WEB8888 Keele, Vaughan, Ontario www.etimeenergy.com
    • eTime EnergySaving Energy Year RoundeTime Energy completed the installation of the HPS-G transparent window coating in May of2009 on a Jack Astor’s Restaurant in Toronto, Canada for SIR Corporation. The goal of thiscase study was to provide evidence that the installation of the HPS-G coating will directlycause a decrease in the usage of air-conditioning and heating throughout the summer andwinter months. A careful comparison of hydro and natural gas usages over a 3-year span wasused to determine the impact of the HPS-G coating. Degree-days were used to equatetemperature differences from year to year.The InstallationThe total application process took 4 nights and did not interfere with the operations of this busyrestaurant, as all work was completed afterhours. The non-toxic, water based nature of HPS-G allowsfor a safe and healthy installation.ObjectiveThe 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 VerificationIn order to accurately locate energy savings, eTime uses standard engineering methods of verificationincluding the degree-day calculation. This formula equates temperatures, eliminating thermostatvariance 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 equipmentwww.etimeenergy.com 2
    • eTime EnergyThe ResultsSum m er 2010 – Average Savings: 32.5% > JULY  2010:  a  30%  reduction  in  AC  use  was  recorded   > AUGUST  2010:  a  35%  reduction  in  AC  use  was  recorded  W inter Starting 2010 – Average Savings: 33% > DECEMBER  2010:  a  34%  reduction  in  heating  use  was  recorded   > JANUARY  2011:  a  37.5%  reduction  in  heating  use  was  recorded   > FEBRUARY  2011:  a  27%  reduction  in  heating  use  was  recorded   Pre-installation Pre-installation eTime Coated eTime Coated8 3007 2506 20054 1503 1002 5010 0 December January February July AugusteTime Energy was therefore able to reduce the AC and heating requirement of thisbuilding by 33 %www.etimeenergy.com 3
    • eTime EnergySummaryBy reducing the heating and cooling loads by an average of 33%, eTime Energy has benefited thisbuilding 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-Gwindow coating reduced the amount of glare entering the restaurant allowing for a better TV visualdisplay in the bar area.Testimonial“The HPS-G coating has created a much more comfortable environment for both customersand staff. Our energy use has been reduced dramatically both in the summer and winterwhile the reduction in glare allows us to gain the benefit of natural light while runningover ten TV units. The installation was great and we are very happy with this product.” - Mark McLaughlin, General ManagerHPS – G Benefits: > 20 – 40% reduction in heating and cooling > Increased comfort levels > Reduced glare > Increased natural lighting > Non-intrusive installation > Reduced UV transmittanceEngineering SupportThis case study has been reviewed and verified by JD Hubbert & Associates.“We have reviewed the calculations and the test results and found that thesavings from the window coating does substantially reduce air conditioning andheating power needed. Since the orientation of the glass has a considerable effecton the loads, the savings would be substantial where the glazed areas are largeand facing west or north west.”www.etimeenergy.com 4

Popularized in the 1980s 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 HeatShields 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!

    • What Most Window Film Manufacturers Won’t Tell You – And WhyIf  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)   % of % of solar % of visible daylight energy Luminous light through through Shading efficacy reflectance Type of glass or applied film glass glass coefficient* constant** 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.  END ARTICLE      http://chiefengineer.org/?p=1586#comment-4995
