Mayo Clinic Locations


Mayo Clinic… world’s first multispecialty group practice

1883 Tornado Hit Rochester Minnesota and a partnership is formed

1889 Saint Mary Hospital Opens

1986-87 Geographic expansion to Arizona and Florida

1992 Created the Mayo Clinic Health System

Three Shields • Patient Care • Education • Research

Mayo Clinic and Mayo Clinic Health System Today

• Charitable, not-for-profit; academic medical center

• Provide essential health care services to 1 million patients annually from more than 135 countries

• $8.8 billion in revenue (net and other sources)

• 3,700 physicians and scientists: 3,900 residents, fellows, and students

• 61,125 – total personnel

• 3,450 beds – 24 hospitals

• Across 6 States


Mayo’s Core Value

The needs of the patient come first

1910 – “The best interest of the patients is the only interest to be considered” – Dr. William J. Mayo at Rush Medical College


Green Committee Goals and Influence

Mission Statement:

“ Mayo Clinic is dedicated to improving the health of its patients

and staff through excellence in the practice of medicine.

Recognizing the linkage between environmental health and

public health, Mayo Clinic is committed to fiscally responsible

environment protection practices in patient care, education,

research, and administration, in order to benefit the health of our

patients, staff, and communities in which they live and work.

Key Stakeholders: • Administration

• Facilities & Campus Management

• Supply Chain

• Surgical Services

• Environmental Services

• Infection Prevention

• Food & Nutrition

• Nursing

• Physician Leadership

• Public Affairs

• Systems Engineering

• Quality Management


Sustainability – Green Committee

• Green Committee is chartered in 2009 in Rochester

• Local grass roots group in Arizona begins and is then officially chartered in 2010.

• Scorecard project is started by Dr. Henry Tazelaar in 2011 who is the Physician chair of the Arizona Green Committee.

• Scorecard project brings communication across regional site working on the same goal.


5 Key Initiatives

• Energy Management

• Waste Stream Management

• Greening the Supply Chain

• Built Environment

• Industry Engagement


Mayo Clinic In Arizona

• 2 Main Campus’s

• 1 Hospital with 268 beds and 21 Operating rooms

• 4 Clinic buildings

• 2 Office buildings

• 1 research building

• 1,417,270 Sq ft


Energy Management – Healthcare Challenges

• Healthcare Building types

• 24 x7 Building operations

• Office Buildings/space

• Research Labs

• Constantly Changing environment.

• Equipment intensive industry

• Fume Hoods

• Operating rooms

• MRI

• Proton Beam


First Steps

• Assign an energy

manager.

• Trend your energy

usage.

• If using utility bills

look at bill days

• I look at daily

averages when

comparing months.


Energy Management

• BTU/ft2/yr - A British Thermal Unit (BTU) is

a standard metric of energy consumption. In

order to compare relative energy use by site

(where energy consumption is in direct

correlation to campus size), the total BTU

consumption is normalized by ft2/yr. This

allows us to compare the ‘energy intensity’

of each site.


Looking at the Data

• 38% to 43 % energy used comes from natural gas

• Heating water for domestic water or space heat

• Steam

• Humidification

• Sterilization

• Kitchen cooking

Energy Management

Houston we have a Problem

Low hanging fruit

Change is the only Constant


Houston we have a problem

• New building with no commissioning.

• Construction of existing building spaces.

• When do you add square footage

• Spending energy to cool air and then reheat it.

• Over ventilation when not required.

• Controls contractor not scheduling setback


Low Hanging Fruit and Improvements

• Commissioning and Retro commissioning.

• Hired a controls programmer in house

• Upgraded chillers with variable frequency drives’s (VFD)

• Replaced central plant controls

• Repaired steam traps

• Replaced lighting to Led when cost effective. • Can lights, spot lights, and under cabinet lights
