Energy Intensity and CO2 Emissions Rising Annually

• Hospitals use 836 trillion BTUs of energy annually1

• Hospitals have over 2.5 times the energy intensity and CO2 emissions of commercial office buildings, producing over 30 lbs of CO2 emissions per square foot2

Presenter

Presentation Notes

Reducing energy intensity also has significant impact on carbon dioxide footprints. Energy-intensive commercial buildings such as hospitals are key. Currently, hospitals have over 2.5 times the energy intensity and carbon dioxide emissions of commercial office buildings. By reducing the energy intensity of this sector, we in turn reduce that carbon footprint. Add renewable energy strategies into the mix as well and hospitals can dramatically extend power reliability during disasters and emergencies, and enhance their standing as proactive community partners.

Escalating Hospital Energy Costs• Rising energy prices and the increasing energy intensity of hospitals

have produced escalating energy costs1

• 91% of hospitals reported higher energy costs over the previous year, and over 50% cited increases in double-digit percentages2

The Interval Data Project

HCA’s energy monitoring initiative utilized a technology platform specifically configured to monitor our hospitals:

• Energy consumption (Kwh)• Peak Demand (kW)• Natural Gas (CCF)• Fuel Oil (Gals)• Water Consumption (Kgal)

Zigbee Network Technology

Presenter

Presentation Notes

This new lighting control technology uses a Zigbee protocol network operating at 2.4 GHz The ZigBee protocol was developed by the ZigBee Alliance to allow companies to cooperate in developing a mesh network protocol that can be used in a variety of commercial and industrial low-data-rate applications. Some Zigbee applications could include networks for Demand Response, asset tracking, facility management, daylighting controls, scheduling of equipment, security, and other personal control devices where high bandwidth is not necessary.

What are barriers to lighting system retrofits?

• Fewer capital dollars• Continued pressure to reduce facility operating

costs• Access to favorable financing and returns

Will Performance Contracting emerge as the funding mechanism for lighting retrofits in

healthcare?


What cost barriers have you encountered in applying new

lighting technologies?

• LED lighting is an expensive first cost• For interior application of LED – for similar

lighting level the appearance isn't there yet

38


What do your hospitals need from vendors to help you overcome identified technology barriers?

• Using the correct bulb type and bulb combinations

• Easy to install retrofit kits to existing fixtures with a clear understanding and agreement on payback analysis

• Optimizing natural lighting, zone sensors, light scheduling, multi-level lighting

39


What tech or service areas are your vendors currently not serving where you see value in exploring?

• Optimizing natural lighting• Zone sensors• Light scheduling• Multi-level lighting

The Challenge Begins…


Energy Conservation vs. Energy Efficiency

Energy Conservation - Means, methods, technology and processes that consume less energy – in other words…

KIDS – TURN OFF THE LIGHTS!


Energy Efficiency vs. Energy Conservation

Energy Efficiency - A device, product or system that uses less energy to obtain a desired result compared to less energy efficient alternatives – in other words…..

KIDS – LET’S INSTALL SOMELIGHTING THAT USES LESS

ENERGY!


When designing lighting solutions we sometimes try a one-size-fits-all approach.


Why doesn’t this work?
