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

DIVERTS MATERIALS FROM LANDFILL
Minimizing materials going into landfills through reuse,
salvaging, and recycling are ways to conserve natural
resources
Lights, metal ducts, and conduits are removed and
recycled. In addition, doors and hardware are
disassemble and packed for redistribution
The construction waste management plan primarily
utilizes on-site co-mingled collection and off-site
materials sorting
