Sustainable Thinking Makes “Cents”

Making the right choices for the right reasons makes the difference. More and more building owners are seeing the value in energy efficiency which makes for sound sustainable business practice. With the right approach sustainability does not have to cost more and to get less. Energy efficiency is a driving factor in sustainable construction. In fact, states are placing more and more emphasis on code development and enforcement. The ASHRAE 90.1 energy code model has been widely adopted by federal, state and local governments. Of course it is always good to comply with code because it is the law, but, it is also good because it can save you money. As we move forward into 2011 we will see ASHRAE 189.1 become the new energy code model. The federal contracting world has already begun writing specs that will incorporate ASHRAE 189.1. Putting logical thinking into building projects and renovations can have a very positive ROI. Some energy efficient tips to consider are:

• Life Cycle cost analysis that takes into consideration how the facility will operate
• Daylighting
• Weigh the pros and cons of increasing insulation of the building envelope
• Use lighting controls
• Control the amount of outside air brought into the building. This will save energy by only cooling the amount of outside air needed for ventilation
• Measurement and verification- re-evaluate. Changes may be necessary to optimize the design in the system once it is being used
• When replacing lights consider updating, ie: change your T12 to T8 or T5 light and ballasts

The little things can add up to huge cost savings. That certainly makes $ense!
