  4. 4. CITY HALL 10-1 COUNCIL SUITE RENOVATIONS 301 West 2nd Street, Austin, TX, 78701 LEED ID+C: Commercial Interiors V3 AWARDED LEED GOLD DEC 2016 COTERA + REED ARCHITECTS Austin City Hall was renovated in 2014 to accommodate an expanded city council. Austin residents passed the 10-ONE charter amendment in 2012 to shift the council from six at-large council members to ten district representatives. The reconfiguration created 5,680 square feet of council member offices, 640 square feet of meeting rooms, and a 450 square foot video conference room, all on the second floor of City Hall. The new wing accommodates 16 full-time employees and eight part-time interns with an average of nine visitors per day. In attaining LEED Gold certification, the renovation project maintains the standard achieved by the original City Hall. The renovation optimizes its energy performance through lighting controls, efficient appliances, and alternative energy sources. The existing fluorescent bulbs were replaced with LED fixtures, and all of the lighting fixtures are controlled by occupancy sensors. Two single-user bathrooms and a kitchen sink were added in the new wing, and water use in these fixtures is 31.8 percent lower than a baseline case. While a typical construction project generates a significant amount of waste, the City Hall renovation was able to divert 100 percent of its construction waste from a landfill. In total, 13.38 tons of metal, sheetrock, and trash were diverted for recycling. The project utilized construction products containing recycled materials; the recycled content amounted to 24.9 percent of the total material cost. In addition to recycled materials, the project used materials that were extracted and manufactured within 500 miles of the site
