Councilmember Strub questioned if the NBCC still required seven rooftop units. TRANE REP commented this was still the correct assessment. He indicated that some adjustments may be made to the strategies for the Eagle's Nest. Jason Hicks estimated the new HVAC units would last 15 to 20 years. He explained the current units were not working at their optimal levels. He provided further comment on the proposed new systems and how the comfort level within the building would be improved, in addition to being more energy efficient. He discussed the air purifying system that would be used at the Community Center. Councilmember Jacobsen questioned what savings the City would see with the new HVAC units. TRANE REP estimated the City would be saving $13,000 per year in energy costs with the new units. Councilmember Burg requested further information on how the air purification system worked. TRANE REP described how the system worked to remove impurities in the air and explained the system would require minimal maintenance every 18 months. Jason Hicks discussed the LED lighting upgrades that could be made at the NBCC. He noted these upgrades would be more energy efficient and would lead to cost savings for the City. Councilmember Jacobsen questioned the payback period for the LED upgrades. TRANE REP indicated the LED lighting upgrades would have a 10 -year payback period. He believed that the LED lighting would provide correct lighting levels at the Community Center. He then reviewed the solar options available for the NBCC. He explained the Community Center was a great facility for solar. Jason Hick commented on how the proposed improvements would lessen the City's carbon footprint while also advancing the City's involvement in the GreenStep Cities initiative. The project costs were reviewed in detail. Staff recommended the Council proceed with Option 1 and 2. The next steps for the project timeline were outlined for the Council. Mayor Johnson stated the expense for this project was quite large. She asked what the City had budgeted for the replacement of the HVAC units. Jason Hicks stated $410,000 was allocated for this specific project. However, it was noted additional funding was available for the project. Davitt reported cash savings could be used, along with money from the energy savings. She explained that if the City Council continues to fund the fleet/non-fleet as planned, the HVAC expenditures could be covered. Lotter commented on how the City balanced its fleet/non-fleet plan on a yearly basis according to the City's needs. He understood this project was coming in higher than expected, but explained the City had the funds to cover the project. Mayor Johnson discussed the proposed expenditure further with the Council and staff. Councilmember Burg supported the City spending an additional $19,000 to upgrade the NBCC building envelope. She believed this would create greater energy efficiencies if completed. She questioned the life expectancy on the proposed solar panels. TRANE REP reported the solar panels would last 20 to 25 years. He noted the typical payback for these units were 10 to 11 years. Mayor Johnson inquired when the City addressed the NBCC fee schedule. Brueur reported staff reviewed the fee schedule every November. She stated rates were typically increased every other year.
