Upgrading equipment alone does not ensure the efficient use of energy.
Before you spend money on retrofits on HVAC, lighting and appliances, think about spending a little more upfront to pay less in the future.
Certainly, if you are constructing a new building, don't forget to take the Integrated Project Delivery (IPD) approach to achieve a High-Performance Green Building. You are going to spend money any way, why not make sure that it will use less energy, save money over time, provide better occupant health and comfort, and protect the environment!
