The Health Benefits of Affordable Green Housing David E. Jacobs, PhD, CIH National Center for Healthy Housing Green Affordable Housing Forum: Protecting the Most Vulnerable While Expanding Washington’s Green Economy March 2009
Outline • Health and Housing Connection • Examples of Health and Monetary Benefits of Improved Housing and Health • Data Needs for Assessing Health Outcomes in Green Development • Preliminary Results of Health Studies of Green Housing • Wheeler Terrace in Washington DC
Florence Nightingale “The connection between health and the dwelling of the population is one of the most important that exists.” Cited in Lowry, S, BMJ, 1991, 303, 838-840
Health in the Late 19th Century • Challenge of Tuberculosis Seemed Insurmountable • Lessons for Public Health Officials, Architects and Planners: Better Ventilation, Reduce Crowding, Improve Housing Sanitation (Plumbing) • With Improved Living Conditions & Medical Interventions, Disease Rates Declined
Re-establish the Housing/Health Collaboration • Green Developers, Builders, Others • Weatherization Professionals • Public & Environmental Health • Housing Professionals • Banks & Other Financial Institutions • Government • Rehab Professionals • Many others
Is Housing a Shared Commons?Is Housing Part of the Infrastructure?

Power of Housing & Health Surveillance Data:Dust Lead and Windows
Benefits of Window Replacement • Lead Dust Accumulation • Energy Savings: Heating and Cooling • Housing Value • Other?
Total Net Benefits of Lead Safe Window Replacement • Pre-1940 Housing • $5,092 x 11 million units with single pane lead contaminated windows = $56 billion • Pre-1960 Housing • $1, 092 x 11 million units with single pane lead contaminated windows = $11 billion • Total = $67 billion
Data Needed for Cost Benefit Analysis of Green Healthy Housing • Housing Conditionsthat Impair Health (1) • HousingImprovements that Advance Health (2)
Housing Conditions That Affect Health (1) • Categories: • Sufficient Scientific Evidence • Some Scientific Evidence • Insufficient Evidence World Health Organization (WHO)
Sufficient Evidence (WHO, 2005) • PHYSICAL FACTORS: • Heat and related temperatures and winter excess mortality • Cold indoor temperatures and winter excess mortality • Energy efficiency of housing and health • Radon exposure in dwellings and cancer • Neighborhood and building noise and related health effects • SOCIAL FACTORS: • Multifamily housing, high-rise housing, housing quality and mental health • CHEMICAL FACTORS: • ETS exposure in dwellings and respiratory and allergic effects • Lead-related health effects • BIOLOGICAL FACTORS: • Humidity and mold in dwellings and related health effects • Hygrothermal conditions and house dust mite exposure
Some Evidence (WHO, 2005) • PHYSICAL FACTORS: • Ventilation in the dwelling and respiratory and allergic effects • CHEMICAL FACTORS: • VOCs and respiratory, cardiovascular and allergic effects • BIOLOGICAL FACTORS: • Cockroaches and rodents in dwellings and respiratory and allergic effects • Cats, dogs and mites in dwellings and respiratory and allergic effects • Pets and mites and respiratory, allergic or asthmatic effects • BUILDING FACTORS: • Sanitation and hygiene conditions and related physical health effects • SOCIAL FACTORS: • Social conditions of housing and fear/fear of crime • Poverty and social exclusion and related health effects • Crowding and related health effects • Social factors/social climate and mental health
Proven Healthy Housing Improvements • Asthma Interventions • Integrated Pest Management • Moisture Intrusion Reduction • Radon Mitigation • Lead Hazard Control • Smoke & CO Alarms • Pre-Set Hot Water Temperature
Breathe Easy Homes:Health Outcomes With $ Benefits • Change in No. of Asthma Symptom Days: • 4.8 days for each two week period (p<0.004) • Change in Caretaker Quality of Life: • 80% improvement (p<0.002) • Reduced Visits to Urgent Care: • 40% reduction (p<0.001)
