- • Energy savings: Hemp's thermal mass reduces HVAC costs ($800–$1,500/year).
- • Health costs: The average family spends $4,000+/year on health issues linked to poor indoor air quality.
- • Property value: Buyer demand for healthier, lower-energy homes is growing, though any resale impact depends on the local market and appraisal.
