Flooring Survey RecommendationsVinyl Composition Tiles (VCT) – Unit Kitchens & Entries
More than 75% recommended
• Durability
• Cost
• Easily replaceable
• Create patterns
![Page 7: BIGGEST BANG FOR YOUR BUCK](https://reader031.vdocuments.site/reader031/viewer/2022013101/56815a25550346895dc7684d/html5/thumbnails/7.jpg)
Flooring Survey RecommendationsSheet Vinyl – Unit Baths & Laundry
Standard Commercial(Armstrong Connection Corlon)
For wet areas need welded joints
Ceramic Tile Recommended
In place of Vinyl
For wearing well & longer life

Flooring Survey RecommendationsVinyl Plank Flooring - Units or Upper Level Commons
Tarkett Vinyl Plank – Popular
Trend to more hard floors away from carpet

Flooring Survey RecommendationsCarpet
For Extremely Low-Income - Avoid Carpet
Used by Majority of Low-Income Asset Managers • Unit BRs & LRs
No consensus between area carpet & carpet tiles

Plumbing Survey Recommendations
1) Use of Efficient Fixtures
2) Stack Piping Infrastructure.
3) Metering Individual Units
4) Central Laundries
Efficiency Measures - Architect’s & Contractor’s:

Plumbing Survey – Efficient Fixtures
• All use low-flow toilets
• All use low-flow shower heads
• 75% use low-flow kitchen & bath faucets
• 70% using Mandatory Evergreen Standards
• 18% using Advanced
Usage by Asset Managers
Evergreen Standards Mandatory Advanced
![Page 17: BIGGEST BANG FOR YOUR BUCK](https://reader031.vdocuments.site/reader031/viewer/2022013101/56815a25550346895dc7684d/html5/thumbnails/17.jpg)
Plumbing Survey – Common Problems
• Garbage Disposals
• Clogging Toilets
• Leaking Piping
Asset Managers Most Common Problems
![Page 18: BIGGEST BANG FOR YOUR BUCK](https://reader031.vdocuments.site/reader031/viewer/2022013101/56815a25550346895dc7684d/html5/thumbnails/18.jpg)
Plumbing Survey – Gray Water
• No usage by asset managers • Gray Water for Plumbing not affordable
• Rain Water Catchment for Irrigation - Possibly
Gray Water System – Mixed Response
![Page 19: BIGGEST BANG FOR YOUR BUCK](https://reader031.vdocuments.site/reader031/viewer/2022013101/56815a25550346895dc7684d/html5/thumbnails/19.jpg)
Plumbing Survey – Solar Hot Water
• Recommended but ….
• Long Term Maintenance Performance not available
Solar Hot Water System – Mixed Response
![Page 20: BIGGEST BANG FOR YOUR BUCK](https://reader031.vdocuments.site/reader031/viewer/2022013101/56815a25550346895dc7684d/html5/thumbnails/20.jpg)
• Stack all plumbing!• Copper or CPVC mains, PEX homerun
distribution manifolds• Low flow everything• Insulate piping!• Wireless submetering of hot water• No irrigation (or use deduct meter)• Solar ready
![Page 21: BIGGEST BANG FOR YOUR BUCK](https://reader031.vdocuments.site/reader031/viewer/2022013101/56815a25550346895dc7684d/html5/thumbnails/21.jpg)
Central Systems• Condensing water heaters vs. atmospheric
boilers• Coming soon...Consider heat pump, waste
water heat recovery, solar

HVAC Survey Results - COOLINGEastern Washington – Full A/C
Western Washington – Common Areas especially Senior Housing
Units & Commons:
• Heat Pumps
• Central Chillers & 4-Pipe
• Heat Pumps or P-Tac Units
![Page 26: BIGGEST BANG FOR YOUR BUCK](https://reader031.vdocuments.site/reader031/viewer/2022013101/56815a25550346895dc7684d/html5/thumbnails/26.jpg)
HVAC Survey Results - Challenges
• Common Area System Over-sized
• Too Complex for Maintenance
• Heat – Venting Synchronized
• Thermostat Setback
• Clearance to Wall Units
