An owner/developer and Net Zero consultant will present lessons learned from two Net Zero projects in Rotterdam, NY. They'll describe how an integrated process and extensive energy modeling allowed the team to optimize the design to lower energy use and control costs. Net Zero Village, 156 units completed in 2016, was one of the first large-scale, market-rate, net zero apartment complexes in the United States. Building on their experience, the same integrated team constructed Solara, a 248-unit Net Zero development which broke ground in early 2018. The presenters will discuss their approach to master building controls for smart ventilation, how PHPP modeling was used to optimize costs and energy use, and how this approach can be replicated.
