Deep Energy RetrofitPurpose of Grant
• Develop a process for cost effective DEREnergy savings should make it cost neutral
• Make it durableAssembly should be expected to last 100
years• Make it duplicable
Process should be easy to learn

Deep Energy RetrofitPlan the work
• Focus on the whole building from the basement slab to the roof peak.
• Integrate the air, water, vapor and thermal control layers so they are continuous and aligned with each other.
• Pay close attention to transitions.

Deep Energy RetrofitWhen to begin?
NOW! Interest rates are lowContractors need workMaterials are going up in price
![Page 17: Retrofitting for Resiliency](https://reader035.vdocuments.net/reader035/viewer/2022062305/56815b1f550346895dc8d4b3/html5/thumbnails/17.jpg)
Deep Energy Retrofit• Inexpensive when done in conjunction with a
planned window and siding replacement• Can be done in stages• Do the basement and attic now using on-bill
financing and wait on the walls until you are ready to replace the windows and siding
