Energy & Water Efficiency 101: Sustainability Basics
Energy 101
Energy Efficiency
Clay Elliott

Maria Quiñones
What does it take to create a comfortable working environment?
Energy Profiles of Buildings
Some energy perspective...
The energy used for only heating and cooling buildings in the U.S. is more than the energy used for EVERYTHING in India.
Buildings account for 40% of the country's energy consumption!
Efficiency as an Energy Resource
Can be thought of like other energy resources (i.e. coal, natural gas, solar, wind)
Energy efficiency is the cleanest of all of these!
Reduces energy demand and cuts losses throughout the energy supply chain
Our energy choices have significant effects on the things we care most about
Lighting
Artificial lighting in most buildings can be reduced through a number of options
New buildings can be designed for daylighting while minimizing direct exposure to sun
Measure light output (in lumens) to provide appropriate amount of light
Projects YOU Can Do Now!
Remove unnecessary light fixtures in overlit areas
Remember to turn off the lights when leaving the room
Educate occupants to use task lighting at desks when feasible as opposed to turning all of the lights on in the room
Replace incandescent bulbs with compact fluorescent bulbs or LEDs (can save up to 80% of the energy used by an incandescent bulb)
Maximize daylighting by opening blinds (minimize any resulting glare by rearranging office furniture)
Artificial light creates unproductive and unhealthy working environments
Building Envelope
Building envelope is defined as the separation between the interior of a building and the outside air (outer walls, ceilings, floors, doors, and windows)
Heat transferred into building during summer and out of building in winter
Minimize this through good insulation and sealing cracks in the building envelope
Projects YOU Can Do Now!
Find places where air is leaking unexpectedly into the building and seal off those areas (prevents your heating and cooling systems from working harder than needed)
If you are in the process of replacing windows, choose those that are energy efficient by cutting down on heat transfer through the glass and sides of the windows
If your building is suitable, plant a green roof!
Heating, Ventilation, and Air Conditioning
Systems comprised of equipment and ductwork that must be properly maintained
Many systems are overworked because of leaks and malfunctioning motors/pumps
Loads on HVAC systems can be lowered by upgrades to other parts of the building
Pay attention to occupant comfort
Projects YOU Can Do Now!
Install a programmable thermostat
Regularly clean/change HVAC filters
Keep exterior doors/windows closed as much as possible
If replacing your HVAC system, ensure that it is properly sized for your space and loads
Have annual maintenance performed on your system
Plug Loads
Now...
Then...
Plug Load Trends
Any electricity consumed from plugging appliances and office equipment into electrical outlets
Using much more energy now than in the past
Greater emphasis can be placed on plug loads when trying to cut energy
Vampire Loads!
Energy consumed by appliances and equipment when not in use
Estimated to cost U.S. consumers more than $3 billion a year
Equipment not in use for extended periods of time should be completely powered off
Projects YOU Can Do Now!
If your budget allows for it, replace old appliances with new, ENERGY STAR certified products
Enable the power management function on computers
Install occupancy sensors or timers on equipment that can be turned off completely when not in use to combat vampire loads
Install vending machine misers (sensors to determine room occupancy and temperature)
Water Efficiency
Projects YOU Can Do Now!
Check regularly for leaks
Consider replacing bathroom fixtures with more efficient models
When landscaping, plant native species to cut down on irrigation needs
Reducing loads on HVAC systems will reduce need for water in these processes
Install rainwater harvesting systems for irrigation and other non-potable water use
Did You Know?
The energy used by a building to support one office worker for a day causes more than twice as many greenhouse gas emissions as that worker's drive to and from work?
Energy Efficiency Opportunities
If the energy efficiency of U.S. commercial and industrial buildings improved by 10%, this would result in:
Savings of $20 billion
Reductions in greenhouse gas emissions equal to about 30 million vehicles
The DOE actually estimates that efficiency can be feasibly improved by 23%!
