Envisioned as the centerpiece of a new multiuse town center, the new city hall for the city of Johnston, Iowa, brings civic, retail, hospitality, office and entertainment opportunities to the area. It also aims to serve as an example of innovation, energy conservation and sustainability for the community.
The city approved a sustainable design by OPN Architects that could earn LEED Silver certification and potentially achieve net-zero energy consumption in the future. High-efficiency building systems and features include mechanical VRV equipment, demand-controlled ventilation, low-flow plumbing fixtures, LED lighting, daylighting and building massing and shading devices to reduce cooling loads.
