- Walls
- Comfort Profile
- Winter
- Coldest spots are the dirt floor areas:
- 1st floor common room
- Kitchen
- Front hall
- Front office
- Lockers
- Men's room
- Spruce street entrance
- There are drafts coming from above the drop ceiling in the locker area as well as the kitchen.
- The floors in this area are also drafty.
- Upstairs, the stairwell windows and southwest facing windows are draftiest
- Coldest spots are the dirt floor areas:
- Summer
- Hottest rooms are the front office, Apt 3 living room, and the bedroom over the door (all southwest facing)
- The common areas stay pretty cool due to the dirt floor
- Condensation, humidity
- Winter
- Inspection and Testing
- Thermal Inspection by Ken Byczynski - Kenco (December 2011)
- Pictures - Kenco Pictures Hostel Detroit
- Observations
- Thermal Envelope
- Ceiling / Roof there is room for insulation (maybe 20 - 25% savings in heating possible.)
- Walls have lathing on brick...no room for insulation
- Floors were installed without any insulation...difficult to do now
- Windows - New-ish Vinyl Windows
- Chalking on the exterior of the windows would be helpful to prevent air infiltration
- Leak under window in back...poor seal around windows
- Doors (not studied)
- Air Infiltration likely an issue.
- HVAC Equipment
- All equipment is on the roof...did not inspect
- Thermal Envelope
- Testing
- Carbon Dioxide test...need to confirm heating units are on the roof
- Blower door test + infrared thermal imaging (Ken)
- Modeling
- Energy Bill Analysis
- Preliminary analysis of total building consumption based on only one year of bills with data missing for some months in a few places and one of the electric meters missing.
- Need to find out the number of days for each billing month listed. For now, just used number of days in month.
- Begin energy model
- Energy modeling checklist
- Energy Bill Analysis

- Michel will try to get common area energy bills
Phase II - No / Low Cost Actions
- Air Infiltration (10 - 15%)
- Doors...weatherstripping / thresholds
- Windows caulk exterior (repair water leak window)
- Venting fans...sealed and on timers
- Outlet / Switch boxes foamed
- Bottom of Siding
- Plumbing stacks
- Maintenance of Current Equipment (5 - 10%)
- Clean or replace filters (every 3 months)
- Setback thermostats
- Seal ducts especially exterior
- Clean refrigerator coils
- Get equipment inspected ($125 each)
- Select Lighting (> 50% reduction of lighting load)
- CFL's in lights (reduce by 70%)
- Photocells outside
- Motion detector on critical lights (on the most)
- Hot Water Tanks
- Check temp make sure not too hot
- Thermal Blanket on each tank ($25 each)
- Turn off / down when not occupied
- Energy Sippers?

- Prototype
Phase II - Holistic
- Reduce Demand - envelop insulation and Air Infiltration
- Windows - R + low-e Coating
- Furnace
Phase II - Low Cost/No Cost brainstorm March 7, 2012
$ Durabond 90 hard sand with paper tape to seal all cracks in walls
$ Weatherproof and sweeps on doors
$$ Balance return and supply air
- Pressure balance ducts
- Relatively cheap to test and balance, compared to adding insulation
- Can check the balance situation with manometer
- Need to know or determine what the airflow rates should be in each space
$$ Silver paint over the tar roof
($$) Caulking done around windows Dec. 2011
$$ Blower door test (through DTE?) for incentives
$$ Spray foam around windows from inside (Home Depot, window and door, blue can)
$$ Tuck point brick
$$$ Water damage needs to be corrected, may also help with infiltration, at least in that spot
$$$ Insulation strategy: (Don’t cover up holes because you would need to uncover to insulate)
- Roof first, insulate from underneath
