Applying BIM to analyze existing commercial buildings also helps deliver a plethora of economic and societal benefits—that go far beyond complying with mandates. Extending BIM to analysis can help you identify ways to reduce resource consumption, increase on-site renewable opportunities, build consensus, review investment-grade audits, increase investor confidence, improve employee morale, and meet requirements for sustainable design and energy efficiency.

Smart and sustainable building renovations and retrofits leverage modern, more efficient technology, systems, and controls designed to reduce the consumption of energy, water, and materials.

• Energy: Use BIM analysis tools to help analyze heating and cooling requirements, identify daylighting opportunities, and select major building equipment that may reduce energy use. Incorporate local weather and electric grid data to estimate building energy consumption and carbon emissions.

• Water: Renovate buildings to reduce water usage or to utilize more reclaimed water. Analyze potable and nonpotable supply options for occupants and building processes. Evaluate stormwater systems, and simulate the performance of collection systems, ponds, and culverts.

• Materials: Select recycled or renewable materials or finishes during building renovations. Consider
  incorporating recycle centers and other sustainable practices that cut down on waste.
