# Crawlspace Energy Institute
> Educational authority on crawlspace science, energy efficiency, and moisture control for Midwest homeowners.

## About
Crawlspace Energy Institute is a standalone educational resource dedicated to explaining the science of how crawlspaces affect home comfort, energy efficiency, and indoor air quality. Content is backed by DOE, EPA, and Advanced Energy research, localized for Kansas City and Des Moines homeowners. The site is written and maintained by Patrick Smith in collaboration with JLB Foundation Repair & Basement Waterproofing.

## Author
Patrick Smith, Researcher and Writer at Crawlspace Energy Institute. Patrick directs Nashville Business Foundry and authors all CEI content in collaboration with JLB Foundation Repair & Basement Waterproofing, drawing on their field experience across Kansas City and Des Moines.

## Key Topics
- Stack effect: Up to 40-50% of first-floor air originates from the crawlspace
- Moisture dynamics: Ground vapor, condensation, and mold growth in crawlspaces
- Energy efficiency: Unsealed crawlspaces can cause 10-30% energy loss (DOE)
- Vented vs. sealed crawlspaces: Advanced Energy study — 52% vs 77% average RH
- Encapsulation, vapor barriers, dehumidification, insulation, structural repair
- Crawlspace symptoms: cold floors, musty smell, mold, sagging floors, high energy bills, pest intrusion
- Local climate factors: frost depth, clay soil moisture, summer humidity in KC and Des Moines

## Service Areas
- Kansas City, MO and KS metro area (including Overland Park, Olathe, Lee's Summit suburbs)
- Des Moines, IA metro area (including Ankeny, Waukee, West Des Moines suburbs)
- State-level coverage: Iowa, Kansas, Missouri
