Figure D1. Buildings with masonry (left), concrete blocks (center), and concrete struc-
tural frame (right) walls have a low R-value.
Figure D2. Poor wall and window insulation illustrated by thermography.
Figure D3. Intended openings in the building envelope in newly constructed (left) and in
retrofi t (center, right) buildings.
Figure D4. Unintended air leakage in the building’s envelope: picture and a thermal
image of the wall in a swimming hall, showing air and thermal leakage area.
Figure D5. Thermal image of the residential building wall with thermal bridges (top left,
top right), concrete structural frame of the offi ce building creates thermal
bridging (bottom).
Figure D6. Left to right: poorly installed and damaged exterior insulation and fi nish
system; wetted perlite material due to the water damage.
Figure D7. Extended building envelope due to courtyard.
Figure D8. Poor sloped-roof insulation.
Figure D9. HVAC equipment installed in an attic.
Figure D10. Flat roof with a low insulation level.
Figure D11. High metal roof surface temperature due to the use of low refl ective paint. Pic-
tures are taken at the outside air temperature equal to 93 °F.
Figure D12. Walls and ceiling of the nonconditioned maintenance facility high bay painted
in dark colors.
Figure D13. Poor insulation and air pass through the attic fl oor.
Figure D14. Metal roof openings.
Figure D15. Unheated basement.
Figure D16. Unsealed interfl oor penetrations.
Figure D17. Examples of single-pane windows with metal frames that create thermal
ridges.
Figure D18. Infrared thermogram indicating areas with heat losses and air leaks through
poorly sealed single-pane windows.
Figure D19. Windows with failed seals.
Figure D20. Examples of poorly sealed window-frames.
Figure D21. Examples of industrial facilities with the excessive wall area fi lled with single-
pane windows.
Figure D22. Example of translucent wall panel, which is more insulated than windows
and allows light through without being vision-transparent: (a) outside and (b)
inside view.
Figure D23. Example of an offi ce building with excessive wall area fi lled with single-pane
windows.
Figure D24. External doors with missing weather strips (left) and a signifi cant gap under
the door (right).
Figure D25. Poorly sealed admin building doors (left) and a hangar door (right).
Figure D26. Examples of buildings with air-conditioned spaces open directly to outside; left
to right, open stairways, open terrace, common open balconies (top row), open
balconies and an open internal hallway (bottom row).
