FROG's high-performance building system is available in three packages, which allows folks with tighter budget constraints to afford sustainable, state-of-the-art buildings. The specification packages range from standard, which meets LEED Silver requirements to highly customized, which meets LEED Platinum criteria. Detailed information about the three packages is provided in the following product matrix. The packages are additive, so by upgrading to level "B," a client can access more options, but still manage its budget by selecting only those items that meet its program needs. For example, one could upgrade to level "C" interiors, but spec level "B" exterior finishes to minimize thecost.
