  1. Sustainable Healthcare

  2. Sponsored by: CENTER FOR MAXIMUM POTENTIAL BUILDING SYSTEMS The Corporate Realty, Design & Management Institute

  3. GGHC The GGHC builds on LEED™ byaddressing the particular structural, usage, and regulatory challenges of healthcare buildings and by emphasizing the environmental and public health issues that comprise an important part of what it means for a healthcare institution to address sustainable construction. Unlike LEED™,the GGHC is structured as a self-certifying system. What are Green Healthcare Facilities? “…buildings that are environmentally responsible, profitable, and healthy places to live, work and heal.”

  4. The Green Guidelines for Healthcare Construction seek to reward organizations that strive to engage in environmental stewardship, and that lead the healthcare industry toward high performance healing environments GGHC sustainable

  9. Acute Care Admissions To Increase 41% 65+ account for 40% Admissions49% Beds 65+ account for 51% Admissions59% Beds Source: Solucient Demographics Drive Demand

  10. 46% More Hospital Beds Are Needed Source: Solucient Demographics Drive Demand

  11. Yet Capital Spending Is Not Keeping Up Between 1997 and 2001 • Inpatient Admissions Rose 7.7% • Outpatient Visits Increased 19.6% • Capital Spending Increased Only 5% 41% of Medical Institutions Are Not Spending Enough to Keep Ahead of Asset Depreciation Source: Hospital Financial Managers Association Source: IFMA HCC & CRD&MI Survey Demographics Drive Demand

  12. Healthcare Impact on Energy The Big Numbers • 3% - Buildings • 4% - Floor Space • 8% - Energy Consumption Energy Consumption/SF • Inpatient 179,400 Btu • Outpatient 79,000 Btu Energy Intensity/SF • Thermal 5.6 kWh • Lighting 11.5 kWh Environmental Impact Data Source: DOE

  13. Medical Waste • Hospitals produce 2 million tons of solid waste a year • 15 pounds per patient daily • 85% is paper, plastic, food and other materials $57 Ton Disposal Fee • 15% has infectious potential $450 Ton Disposal Fee • 4th largest source of mercury discharge into environment • Mercury is highly toxic • Medical waste incineration is a major source from mercury-containing devices and histopathological wastes • Lamps are another source Environmental Impact

  14. Saving Energy Equals Millions in Revenue Sustainable Economics Equivalent revenue of $50,000 in annual energy savings (annual savings divided by net margin)

  15. Which Earned More Money? Sustainable Economics $100,000 Invested 1/’97 - Amounts shown exclude return of initial investment

  16. Lighting For Sustainability • 75% of healthcare floor space is illuminated 100% of time • Design lighting to occupant & task - IESNA suggestions: • Nurse Station 53 FC • Patient Room 30 FC • Task Lighting 50 FC • Ambient Lighting 25 FC- Offices with Computers • Maximize fixture, lamp and ballast efficiency • Use automatic controls • Optimize maintenance and disposal practices

  17. Environmentally Responsible Lighting 1 - 1970’s • 2’ x 4’ Fixture, (4) T1234 Lamp8’ x 8’ Layout, 24,656 Lamps, 2.9 W/sf 2 - Mid 1980’s • 2’ x 4’ Fixture, (2) T1234 Lamp8’ x 8’ Layout, 12,328 Lamps, 1.7 W/sf 3 - Mid 1990’s • 2’ x 4’ Fixture, (3) T8 Lamp8’ x 8’ Layout, 18,492 Lamps, 1.4 W/sf 4 - Low Mercury Alternative • 2’ x 4’ Fixture, (3) T8PLC Lamp8’ x 8’ Layout, 18,492 Lamps, 1.4 W/sf 5 - Save Energy & Low Mercury • 2’ x 4’ Fixture, (2) T8PLC Lamp8’ x 10’ Layout, 9,862 Lamps, 0.8 W/sf Total Grams of Mercury 355,000 SF.

  20. White Roofs Are Cool • Nearly half of US population lives or works in a heat island • Dark roofs cause 38% of heat island effect • On a Sunny Day 95° F • Dark Roof 180° F • White Roof 110° F • Energy Star Roof Criteria •  65% Initial Reflectance •  50% Reflectivity after 3-yrs. • Roofs are 5-10% of building cost, yet account for 60-80% of litigation

  21. White Roofs Are Cool Money Makers Source: DOE - ORNL

  22. Auditing Operations & Maintenance Things to Look At: • Lighting • Building Envelope • Controls • Testing, Adjusting & Balancing • Air Handlers, Fan Coils, Baseboard Units • Heating & Cooling System • Security Systems & Procedures • Housekeeping • Roads & Grounds Typical Savings 5-15% & Better Performance

  23. Be Healthy, Clean Safely, Save Money • Clean for health first and appearance second • Evaluate products and buy least toxic product available • Selected disinfectants based on purpose and efficacy • Clean, then disinfect • Educate workers on proper cleaning methods and use of hazardous cleaning products • Take advantage janitorial pollution prevention projects

  24. Is This Your Healthcare Facility? Dust & Microbial Contamination • 70% Airborne, 63% Not Visible • 100 Microns of Dust on Coil Cuts Cooling Capacity 10% • 20-30% increase in annual energy costs Sick Building Syndrome • Productivity & Absenteeism Legionnaires’ Disease • 50,000 to 100,000 Cases/Year 15% Death Rate - CDC Indoor Air Quality

  25. Ultraviolet Germicidal Irradiation - UVGI • The germicidal wavelengths are located around 254 nanometers in the UV-C band • Controls fungi in HVAC systems to reduce or eliminate mold-related allergies • Prevents the development of Legionella and other bacteria … provides a recognized control strategy for tuberculosis • Predictably reduces the spread of cold and flu viruses and other airborne-transmitted diseases Indoor Air Quality

  26. Children’s Hospital - SUNY Buffalo Neonatal Intensive Care Unit • Serial bacterial and fungal cultures on HVAC system and tracheal aspirate (TA) from intubated infants • Microbes isolated from HVAC system were identical to those in NICU and TA • Pseudomonas, Klebsiella, • Bacillus and Serratia • After UVGI was installed “total microbial load markedly decreased” Source: Dr. C. Leach, Dr. R. Ryan Indoor Air Quality

  27. Economics of UVGI Energy Reduction 112,075 kWh/yr. Cost of Electricity $0.1168 kWh Energy Cost Savings $13,090 Maintenance Cost Savings $500 Total Annual Cost Savings $13,590 UVGI System Installed Cost $10,000 UVGI Lamp Annual Replacement $1,350 • Simple Payback .74 Years • Return on Investment 136% Indoor Air Quality

  28. How Much Water Do Hospitals Use? 200 Bed Hospital - 18,200,000 Gallons per Year 300 Bed Hospital - 33,500,000 Gallons per Year Water Efficiency
