ATTACHMENTS: Recommended Quotes APPROVED BY: ddj RECOMMENDED ACTION: Discussion ISSUE Staff wishes to update the Council on the following two items listed in the CIP for purchase in 2016: •Irrigation master control system ($75,000 budgeted in Equipment CIP) •HVAC master control panel for City Hall ($85,000 budgeted in Building & Facilities CIP) The following quotes were acquired for these items; the recommended quotes (in bold) are attached. Irrigation Controller MTI Distributing $51,968.57 Irrigation Controller Central Turf & Irrigation Supply $51,528.51 HVAC Control Panel Yale Mechanical $84,955 HVAC Control Panel Corporate Mechanical $84,360 HVAC Control Panel NAC $82,444 BACKGROUND The following information is provided to inform the Council of the benefit and need for these items. Irrigation master control system We currently maintain 160 acres of park and public building space throughout the City. Approximately 90 of those acres in 20 locations are irrigated with an average of 18-20 million gallons (mg) of water per year. With a renewed focus on the importance of water conservation, staff is interested in installing a master control system that is expected to save approximately 5 mg of water per year, as well as 150-200 hours of staff time per year. The master control system has numerous features that will result in reduced water usage and staff time, as well as other efficiencies: 2 • The system is equipped with weather stations that measure key metrics such as evapotranspiration, relative humidity, sun radiation, wind speed and temperature. Using this data, the system will automatically adjust runtimes to accommodate existing conditions, automatically suspending operation during periods of rain or high wind. With our current system, a staff member needs to drive to each location to adjust the timers as weather conditions dictate. • The system is equipped with flow sensors that will automatically shut down the system when a leak is detected. Staff has estimated that leaks or broken heads occur roughly 25 times per season, with significant water loss each time. With the new system, such occurrences will be detected automatically and staff will be alerted immediately. This will help eliminate the possibility of significant damage to the surrounding turf when a leak goes undetected for hours or days, as sometimes is the case now. • The system is controlled wirelessly with a tablet, which is included in the purchase price. The individual irrigation systems can be shut down with a few clicks on the tablet, so when a non-weather- related event is planned (athletic event, picnic, or other public gathering), a staff member can make adjustments to the system from any location (even from home, and even on weeknights, weekends, and holidays). Regular schedules can be resumed with a few clicks on the tablet, as well. • An unlimited number of irrigated locations can be added to the system at any time, including private irrigation systems. This may give the City the opportunity to explore partnerships with HOAs and businesses which may result in significant water conservation on a city-wide level. The control system is expected to cost $51,529 for the equipment, plus $2,400 annually for the wireless communication service ($120 per year, per location). Installation, setup and data entry is likely to require approximately 250-300 hours of internal staff time for the first year. Ongoing staff time to maintain the system will be very minimal. Using $2.60 per 1000 gallons as the cost of irrigation water, the system is projected to pay for itself within six years and has an IRR of 10% over 10 years. HVAC master control panel at City Hall The HVAC control panel at City Hall is 15 years old. The technology is outdated and it needs to be replaced in order to ensure proper functioning of the HVAC system. The software that runs the current system is not compatible with recent versions of Java, resulting in periodic HVAC system malfunctions whenever Java updates are initiated across the IT network. Furthermore, because the control panel is near the end of its expected life, the manufacturer is no longer supporting the equipment, so maintenance and repairs will be difficult, if not impossible. If the control panel fails, the thermostats will not function properly and cannot be operated manually. This will cause the HVAC system to run at extreme temperatures until a new panel and thermostat control system is in place. Staff is recommending the purchase of a new control panel that will utilize current technology and be compatible with the current network setup at City Hall. The expected cost of installation and training is $82,444. The new panel will have the following benefits: • Web-based access to the controls; authorized staff members can have access from any location • Ability to adjust temperatures in all 63 zones during nights/weekends/holidays to conserve energy when areas of the building are unoccupied (current system cannot control the north half of upper City Hall). • Advanced setup schedules, trend logs, alarms and remote alarm notification for critical equipment • Potential energy savings with zone optimization and improved comfort strategies 3 Staff is also recommending the purchase of the two Alternates listed in the quote: • Alternate 1 - Up to 24 adjustable sensors ($65 each) to allow zone-specific temperature override ability (these will replace the existing small dial boxes located throughout the building) • Alternate 2 - Toxic & Combustible Gas Monitor for the PD garage ($1,450). The existing CO detector is not functioning; a reliable unit should be installed as soon as possible. The total cost of the control panel, additional sensors, and gas monitor is $85,454. The contractor will apply for an Xcel Energy rebate on the City’s behalf. The rebate is expected to be in the range of 10-25% of the overall project cost, bringing the net cost down to $64,100 - $76,900. SUMMARY Staff is requesting Council feedback and direction on the purchase of these items. Pending Council feedback, a request for City Council authorization to purchase the equipment will be brought forward at the March 15, 2016 Regular City Council meeting.
