    Case Studies In Aerial Thermography Case Studies In Aerial Thermography Presentation Transcript

    • Applications for Aerial Infrared Thermography Contact:   Dean  Nelson,  General  Manager     Aerial  Thermography,  Inc.     dnelson@aerialthermography.net   (303)  279-­‐8234   www.aerialthermography.net  
    • Case Studies Aerial  Thermography,  Inc.   OpJmizing  Energy  Resource  Management   Applications for Aerial Thermography: Energy Audits An  ideal  applicaJon  of  aerial  thermography  is  the   measurement  between  surface  temperatures  of  a  building  (usually   aQer  sunset  when  the  heaJng  effects  of  the  sun  are  not  a  factor)   and  the  ambient  temperature.     In  this  image  of  a  warehouse,  there  are  three  disJnct   temperatures  for  different  parts  of  the  roof.  The  ambient   temperature  outside  is  well  below  freezing  (12  degrees).  The   ground  cools  down  fairly  slowly  aQer  sunset,  reading  about  45   degrees  on  the  south  side  (boUom  of  the  picture).  The  main  part  of   the  warehouse  is  measuring  about  32  degrees  and  the  secJon  on   the  right  is  measuring  in  the  mid  20s.  The  area  on  the  right  side  is   newer  and  has  more  insulaJon  than  the  middle  part,  so  the  outside   surface  of  the  roof  is  cooler.  The  area  at  the  top  leQ  is  part  of  an   open  bay  –  it  has  a  roof  but  no  sides,  so  the  metal  of  the  roof  cools   down  quickly.  The  roof  didn’t  have  surface  maintenance  issues,  but   it  did  show  that  the  lower  vent  in  the  middle  of  the  roof  was  le[ng   out  too  much  heat  (evidenced  by  the  reading  in  that  area  of  over  60   degrees).  On-­‐site  inspecJon  confirmed  that  the  vent  system  had   jammed  and  that  it  needed  to  be  repaired.     Photo  Copyright  Aerial  Thermography,  Inc.   April,  2010   Copyright  Aerial  Thermography,  Inc.   2  
    • Case Studies Aerial  Thermography,  Inc.   OpJmizing  Energy  Resource  Management   Applications for Aerial Thermography: Detection of Maintenance Problems Energy  audits  can  be  conducted  effecJvely  when   there  is  the  greatest  variance  between  the  outside  ambient   temperature  and  the  temperature  inside  a  building.     In  order  to  miJgate  the  effects  of  warming  due  to  sunshine,     the  best  Jme  to  conduct  an  energy  audit  is  aQer  sundown.         If  the  images  are  captured  within  a  window  just  aQer     sundown,  addiJonal  informaJon  is  manifested;  like  the     different  cooling  off  speeds  of  a  dry  roof  versus  a  wet  roof.       In  the  case  of  this  image,  the  surface  of  the  roof  was  dry,     but  there  was  an  indicaJon  that  parts  of  the  roof  (the  red     streaks  emanaJng  from  the  corners)  were  water-­‐logged     and  damaged  (the  damaged  area  was  more  than  15  degrees   warmer  than  the  dry  porJons  of  the  roof).    This  was     confirmed  by  people  inside  this  government  building  who     said  they  had  a  leaky  roof  in  the  concourse  between  the   main  buildings  –  which  is  what  this  shows.       Of  parJcular  interest  is  that  oQen  the  leak  inside  does     not  indicate  where  the  problem  at  the  roof  level  is     located  –  water  will  travel  down  any  incline,  from  beams  to  insulaJon,  and  in  this  case  it  seems  that  rather  than  replacing  the   enJre  roof,  some  work  on  the  flashing  is  required  (unless  it  has  been  leQ  too  long  and  the  roof  itself  is  compromised).   Photo  Copyright  Aerial  Thermography,  Inc.   April,  2010   Copyright  Aerial  Thermography,  Inc.   3  
    • Case Studies Aerial  Thermography,  Inc.   OpJmizing  Energy  Resource  Management   Applications for Aerial Thermography: Detection of Maintenance Problems Aerial  thermography  is  parJcularly  effecJve  at  detecJng   issues  with  roofs  that  seem  to  be  in  good  shape  but  are   showing  evidence  of  leaking  inside.      In  the  first  image  of  a  fast-­‐ food  restaurant,  while  the  roof  seems  dry  to  the  naked  eye,   that  parts  of  the  roof  over  the  play  area  show  an  area  that  is  5   degrees  warmer  than  the  surrounding  roof  areas  is  an   indicaJon  that  there  might  be  a  buildup  of  water  between   layers  of  the  roof.   In  the  two  images  on  the  boUom  we  can  see  that  there  is   significant  water  and  ice  buildup  on  this  roof.    The  water  and   ice  were  not  visible  from  a  simple  visual  inspecJon  because   they  were  hidden  by  three  inches  of  loose  gravel.  On  the  same   roof  (far  right/boUom)  we  detected  significant  heat  loss  and   water  leakage  into  the  roof.    The  leakage  wasn’t  visible  from   above,  and  may  not    have  been  visible  from  below,  but  the   problem  only  gets  worse  as  the  roof  contracts  and  expands   with  temperature  changes.   Photos  Copyright  Aerial  Thermography,  Inc.   April,  2010   Copyright  Aerial  Thermography,  Inc.   4  
    • Case Studies Aerial  Thermography,  Inc.   OpJmizing  Energy  Resource  Management   Applications for Aerial Thermography: Detection of Maintenance Problems In  this  image  we  see  a  series  of  row   houses.    We  can  see  that  the  roof   temperatures  vary  by  over  20  degrees,   indicaJng  various  levels  of  insulaJon.       We  can  also  see  the  sources  of  heat   loss  and  the  difference  between  a  roof  in   good  condiJon  indicated  by  a  consistent   temperature,  and  one  in  need  of  repair,   indicated  by  a  wide  range  of  roof   temperatures.   Photo  Copyright  Aerial  Thermography,  Inc.   April,  2010   Copyright  Aerial  Thermography,  Inc.   5  
    • Case Studies Aerial  Thermography,  Inc.   OpJmizing  Energy  Resource  Management   Applications for Aerial Thermography: Evaluation of Construction and Repairs The  following  image  has  detected  two  readings   of  interest.    The  image  was  taken  in  the  early  evening   aQer  sunset  and  shows  the  ground  cooling  off  slower   than  the  insulated  roof  of  the  buildings.    There  has   been  a  repair  to  the  roof  on  the  top/leQ  side,  and  it   is  showing  that  the  temperature  is  lower  –  an   indicaJon  that  that  part  of  the  roof  has  beUer   insulaJon  and  that  the  repair  was  done  properly.       There  is  a  red  spot  on  the  roof  ( just  under  where   you  see  a  pickup  truck  in  the  image)  and  this   indicates  a  higher  temperature  by  over  15  degrees  –   a  clear  indicaJon  on  a  visually  dry  roof  that  there  is  a   leak  and  that  water  has  built  up  under  the  surface.   This  part  of  the  roof  may  not  show  signs  of  damage   either  inside  or  outside  but  by  the  Jme  it  does,   repairs  might  be  much  more  costly  –  and  whatever  is   inside  the  building  (merchandise,  computers,  books,   furniture,  etc.)  may  have  been  damaged  as  well.     Photo  Copyright  Aerial  Thermography,  Inc.   April,  2010   Copyright  Aerial  Thermography,  Inc.   6  
    • Case Studies Aerial  Thermography,  Inc.   OpJmizing  Energy  Resource  Management   Applications for Aerial Thermography: Electrical and Mechanical Surveys This  is  the  image  of  a  photovoltaic  facility  in  Colorado.     Infrared  imaging  can  detect  when  the  solar  panels  are   operaJng  efficiently,  since  they  put  off  more  heat  when  they   are  not  working  properly.    In  this  case,  a  variance  of  more  than   ten  degrees  between  the  ambient  temperature  and  the  panels   indicate  a  problem,  and  the  problem  is  more  pronounced  in   specific  areas.    This  image  was  not  taken  as  part  of  a  contract,   but  while  we  were  flying  between  two  jobs.    If  we  were   contracted,  we  would  conduct  a  detailed  survey  with  higher   resoluJon,  that  would  be  perpendicular  to  the  ground  and  at  a   fixed  alJtude  so  that  the  map  we  provided  to  the  clients  would   enable  them  to  detect  performance  on  a  panel  by  panel  basis.   Mechanical  surveys  can  range  from  measuring  tank  levels   at  oil  and  gas  faciliJes  to  validaJng  HVAC  systems  versus   normal  operaJng  temperatures,  etc.   Photo  Copyright  Aerial  Thermography,  Inc.   April,  2010   Copyright  Aerial  Thermography,  Inc.   7  
    • Case Studies Aerial  Thermography,  Inc.   OpJmizing  Energy  Resource  Management   Applications for Aerial Thermography: Geothermal Prospecting Aerial  thermography  has  a  lot  of  promise  in  the  prospecJng  for   geothermal  resources.    In  the  image  at  right  we  see  a  bright  area  in  the  top   right.    This  is  a  surface  manifestaJon  of  a  geothermal  area.    The  orange  areas   indicate  blind  geothermal  potenJal  where  there  are  no  surface   manifestaJons  detectable  on  a  regular  aerial  photograph  (other  than  lighter   color  sediment/sand).    It  is  obvious  that  any  further  geothermal  tesJng   should  be  conducted  southwest  of  the  surface  manifestaJon.   In  the  images  below,  we  can  see  an  aerial  photograph  of  a  swamp  near  a   road  from  Google  Earth™,  but  when  imaged  with  an  infrared  camera  (from   very  close)  we  see  that  there  is  a  heat  source  in  the  middle  of  the  swamp   that  was  not  known  even  to  people  who  travel  the  road  every  day.   Photos  Copyright  Aerial  Thermography,  Inc.   April,  2010   Copyright  Aerial  Thermography,  Inc.   8
