## Heat Waves & Heat Related Deaths 

- UHI By Any Other Name . . .

**Heat Waves & Heat Related Deaths**** **

**Heat Health Watch Warning System - ****Developed by University of Delaware in conjunction with City Health Dept-now adopted by National Weather Service office for Phila area **
**ID offensive air masses (moist & dry tropical)**
**Level of Advisory (ER, Alert & Advisory)**
**Forecast heat index >105 issue warning**
**Agency & Media Notification /Nursing &Personal Care /EMS staff**
**Buddy System**
**Heat Line # activated**
**Inspection of group homes /Home Visits**
**Senior Center hours expanded**
**Halt utility terminations **

## Heat Waves & Heat Related Deaths 

- UHI By Any Other Name . . .

**Heat Waves & Heat Related Deaths**** **

**Philadelphia’s 3“killer” heat waves in the last 10 years**
**118 deaths in 1993**
**61 deaths in 1995**
**67 deaths in 1999**

**Cool Homes Program – Energy Coordinating Agency**
**Reduce indoor air temp without increasing utility bills**
**Maximize passive cooling & ventilation / Minimize A/C **
**Reduce occupant health risk **
**Reduce utility delinquencies / terminations**
**Extend Roof Life / reduce C&D landfill waste**
**Improve Indoor AQ**
**  **

## Rx: White, acrylic elastomeric roof coatings 

- Cool Homes Cont.

**R-38 insulation**
**Air sealing**
**Window mounted whole house fan**
**Restore function of windows - window security, screens & shades **
**Weatherization and other referrals**

**Rx: White, acrylic elastomeric roof coatings **

## Independent Evaluation

- Cool Homes Cont.

**Data loggers in 35 houses - pre & post monitoring on 1****st**** and 2****nd**** floors**
**Coatings are nearly eliminating the impact of solar heat gain through the roofs (80% reduction)**
**Indoor ceiling temps were reduced by approx. 5 degrees on hot days & bedroom air temp by approx. 2.5 degrees**
**Temperature change should reduce daily cooling loads by about 30,000 Btus – or the equivalent of nearly 4 hours continuous runtime for a typical 8000/Btu/hr window air conditioner **

## ICLEI 

- Direct Hit

**Cities for Climate Protection:  **
**GHG emissions inventory**
**Base Year 1990 = over 14,000,000 tons of carbon dioxide emissions **
**Projected 2010 emissions = just over 13,000,000 tons CO2 (5-6% reduction based solely on declines in population and manufacturing) **

**ICLEI **

## City’s ICLEI Goal – 10 % reduction of 1990 CO2 emissions level by 2010
