Explanation
When developing the project and building construction budget, the project team should incorporate time in the schedule for unique materials and systems. This is because some green building strategies may require materials or systems that are not readily available or familiar to the local market. For example, using recycled or salvaged materials may require more time for sourcing and delivery. Similarly, installing renewable energy systems or high-performance HVAC systems may require more time for design and commissioning.
Therefore, the project team should plan ahead and allocate sufficient time for these aspects of the project. References: LEED v4 BD+C Reference Guide, Integrative Process, page 28
