Especially if your project is very energy efficient, you will probably be able to pay less for green power based on your energy model than you would using the default values from
Running estimated calculations early in the design stage will help to give you a better understanding of how much the credit might cost. Just keep in mind that the cost may change once the energy usage is further defined as part of your calculations for EAp2 and EAc1: Optimize Energy Performance. If you are using an energy model per Option 1 of EAc1, the cost of RECs might change if alterations to the energy model are required after the LEED design review, but the change should be minimal.
The lower your building’s energy use, the less you pay for this credit (because you have less electrical power use to offset). Explore cost-effective ways of reducing electrical energy consumption in order to reduce the cost of green power.
Some universities and large companies have already decided to purchase green power and therefore your project may not have to pay for it directly. Consult with the owner to see if this is already happening and you can use previously allocated funds rather than project funds. You will need to make sure there is no “double-dipping”.
Many projects see this credit as one for which you pay but don’t receive a tangible benefit. However, nonrenewable electricity production is a huge contributor to pollution and global climate change, and buying green power supports the development of
Using the estimated budget to integrate certified wood into the design and specs early in the process can help prevent costly change orders during construction.
Include a cushion for this credit in case of changes in design and purchasing. For example, if you are counting on one point for using 50% certified wood, plan on using 60% of your
