FACILITY REVIEW LIGHTING

Transcription

1 FACILITY REVIEW Johnson Controls Inc. (JCI) has conducted a brief facility walkthrough to gain a very high level overview of the current needs within the Districts facilities. The following are some of the areas of improvement that were identified. LIGHTING - The lighting throughout the facilities was renovated in early 2000 with 1 st generation T8 and electronic ballast technology and CFL Wall Packs exterior lighting. LED technology has advanced greatly within just the last few years and costs have significantly decreased. There appear to be significant energy saving opportunities with lighting at both campuses.

2 HVAC The HS/MS building is heated and cooled primarily by a Boiler/Chiller system that was installed at the same time the School was built. There are portions of the building that are steam radiators and window A/C units. The District is starting to experience numerous failures of the individual classroom units, water and steam piping, and the mechanical equipment. This is not due to a lack of maintenance but simply the fact that the infrastructure is approximately 60 years old and at the end of its life expectancy. Numerous failures are also starting to occur in both the water piping and the steam condensate return lines. The window A/C units are dated, energy inefficient and noisy. Two Titusville Boilers are original, inefficient and leaking in some instances Boiler leak causing Jacket Deterioration Pipe Deterioration and Failure

3 Condensate Return failing/leaking Chilled Water Pipe failing/leaking Old Inefficient Locker Rm Furnace Fresh Air Dampers no longer operable 1960 s Era R-22 Chiller and remote Condenser are inefficient and starting to have maintenance issues. Parts are becoming non-existent, R-22 refrigerant stopped being manufactured many years ago and has become hard to find and extremely expensive due to EPA mandates s Era Air Handlers Typical HS/MS Classroom Unit Ventilator

4 HVAC - Elementary School is heated with an older Smith Steam Boiler piped to radiators in the classrooms. The rooms are cooled with older inefficient window A/C units. The window unit noise presents a problem with the interaction between the students and teachers; the noise becomes a distraction for the younger students. The condensate return for the steam boiler is starting to deteriorate is sections. Elementary School Boiler is dated and Inefficient Typical ES Classroom Radiator Typical Classroom Window A/C Window A/C Units 1930 s Heating System for Gym

5 WEATHERIZATION Throughout the facilities you will find many areas of heat loss/heat gain in the building envelope. These are generally door and window seals, pipe penetrations etcetera that at first glance, and individually, seem insignificant. But in reality when added cumulatively make a significant impact on both comfort and energy consumption. HS Exit door leaky weatherstripping HS Exit door gaps around sweeps Air Gaps around all, Single Pane Glass, Metal Frame and Caulking deteriorated. Most of the doorways at the HS are old and leaky. Besides energy; gaps around doors and windows will also lead to pest management issues. Cracked Glass in Areas Deteriorated roof deck leaving large air gap

6 This Window System around the building is Single Pane Glass/Metal Panel. The system is energy inefficient, leaky, drafty and deteriorated.

7 HVAC CONTROL SYSTEM Currently there are varying HVAC control systems throughout the buildings. Most are found to be regular thermostats with a dated Johnson Controls system controlling setback. We would recommend a common District wide control system for all buildings. Control and setting could be maintained via secure site on the web thus saving energy and some maintenance cost. Dated JCI Metasys for Setback only Typical Temperature Control Antiquated Pneumatic Control System Old Compressor for Pneumatics

8 OTHER HS/MS ROOF The roof has been coated with foam and sealed at some point in the past. In general the overall repair is in fair condition although there are some areas that need to be addressed as soon as possible. If the thin seal coating which is the only water barrier is penetrated or compromised this roof material will act as a sponge to absorb water. Unfortunately it is generally not noticed until it is completely saturated. There are a number of holes and cracks that need to be resealed. (Structural) Holes in the thin layer of water barrier that need to be addressed ELECTRICAL- There are some areas of safety concerns and upgrades throughout the buildings that need addressed. (Safety) Open junction box in Equip Rm HS Open breaker slots on live electric panel on the stage of elementary school. This panel is mounted low enough young children can easily reach into or stick something in slots.

9 BLEACHERS- The bleachers at the HS are original wooden and Manual Opening. We highly suggest at a minimum installing an automatic or assisted opening system. These manual opening bleachers are found to be a common contributor to back injuries and thus workers comp claims or worse. (Safety) DOMESTIC HOT WATER-The Water Heaters are old and inefficient. There are a number of leaks starting to form. (Energy/Safety) DRAINAGE- There are areas with drainage that need addressed. (Structural) Area on South HS/MS needs re-terraced for drainage, drains back to building in areas. Downspout Missing ES Need to divert water from building

10 BATHROOMS-The Bathrooms are simply dated and could use updating at both the HS/MS and Elementary. There are areas where ADA access could be implemented. There are water savings, ADA compliance and disease prevention with the addition of low flow touchless fixtures. (Water Conservation/Structural) Standard 60 s Era RR HS/MS Non-Compliant Restricted Access HS/MS ES Manual Flush ES Dated Stalls POOL-The Pool equipment is in deteriorated condition. The water heating equipment is not operable and storage tanks leaky. (Energy, Structural) Pool Equipment Room dated and inefficient equipment.

11 SECURITY- The main entry to the HS/MS building could easily be retrofitted into a locking vestibule to address possible security (intruder) concerns. This should be the only unlocked access into building during school hours. IT/PHONES- The current phone and intercom system is dated. Investigate the savings of VOIP and update intercom/alarm/ IT infrastructure. Dated ES Communication Infrastructure Dated HS Communication Infrastructure

12 RECOMMENDATIONS: Simple Web Based HVAC Control System (Energy & Operational Savings) Upgrade of current HVAC Systems. Suggestion; VRF or Mini Split Systems. They are highly energy efficient, quiet and provide individual classroom control. This option eliminates all old boilers, pneumatic controls, chillers, water piping, steam piping, radiators, steam traps, valves and noisy window units. (Energy & Operational Savings/Health/Improved Learning Environment) Introduce adequate fresh air throughout (Comfort/Health/Safety) Interior/Exterior LED Lighting throughout (Energy & Operational Savings) Weatherization (Energy/Comfort) Window System Replacement HS/MS. Would recommend removing window panel system, framing in, insulating, install a couple simple commercial windows in each room, finish exterior with EFIS or quality asthetically pleasing siding material, drywall and paint inside. This new insulated wall would be a great place to incorporate the new Mini Heat Pump units for HVAC. This would be the least expensive option to eliminate all old glass and metal panels and solve comfort, water and energy issues. (Energy Savings/Comfort/Structural) Seal all holes and penetrations in the foam roof with quality elastomeric product. (Structural) Phone, IT System and Networking Upgrades (Operational Savings/Security)

13 SUMMARY Based on very preliminary analysis can see some cost reductions to the District with the right design and upgrade of the current systems. There are also lingering and ongoing operating cost per square foot that is not taken into consideration. That number is high and will continue to escelate since the current heating and cooling systems are at the end of their expected life cycle and will continue to fail on a more frequent basis. Unfortunately as well there is an issue with the primary structural window system at the HS/MS. Here are my suggestions for your facilities. 1) Controls Update: This is generally a self funding payback based on energy alone. Excess savings can be used to help fund a portion any additional upgrades. 2) Phone and IT infrastructure upgrades may be self funding. 3) HVAC Upgrades with the new very high efficiency systems have a substantial payback when operational savings are considered. a. Opreational Savings = Ongoing and escelating high repair costs on aging and failing equipment, and the phase out of R-22 and its skyrocketing cost; (if nothing is done) b. Capitol Cost Avoidance = Replacement is inevitable and needs to be done ASAP. Considering the current cost of money and standard inflation it is less expensive now than anytime in the future. 4) Windows have a negative Cost to Energy Savings ratio but it is something that will have to be addressed soon. It certainly contributes heavily to energy, classroom comfort, and quality learning environments. a. Operational = Continual Repair of leaks and possible (much more expensive) associated structural damage b. Capitol Cost Avoidance = Replacement is inevitable and needs to be done ASAP. Considering the current cost of money and standard inflation it is less expensive now than anytime in the future.

14 What Next? If interested in pursuing solid pricing and payback estimates, the District may issue and RFQ Solicitation for pre-qualified pre-bid firms participating in the state FCIP program. (We can help and have generic drafts of similar RFQ s) Once a Qualified firm is selected then that firm will invest in the resources to gather preliminary scope and budget pricing. Once the budget costs and savings numbers are procured by the selected firm, they are reviewed by the District and a scope and budget agreed upon (negotiated). Up to this point there are no financial or contractual commitments by the District to the selected qualified firm. If it looks to the District as something they wish to seriously pursue you would move to the next step of indepth engineering study and firm guaranteed price and savings numbers. This step would require a Project Development Agreement (PDA) which is simply a good faith document between the District and the selected firm stating that as long as the final cost and design is within the previously agreed to preliminary scope and budget it is the intent of the County to move ahead with a project. An Energy Saving Performance Contract (ESPC) guarantees that specific improvements to a building will deliver a certain amount of savings over a fixed period of time. The costs of facility and infrastructure retrofits or renewal projects can be offset by the energy and operational savings that are achieved as a result, helping government orginizations to maintain cash flow. An ESPC allows customers to make capital improvements, conserve resources, reduce emmisssions, improve sustainability and address tight budgets. If Johnson Controls does not achieve the guaranteed savings, we pay you the difference between what was guaranteed and what was actually achieved. Johnson Controls helped to establish energy performance contracting in 1983, and we ve since delivered it to a wide variety of orginizations such as schools, hospitals, universities and governments. We have implemented more than 3,000 performance contracts with total active guarantees of more than $6.6 billion in North America alone. As a fortune 100 company with top financial ratings and 125 years of experience in energy saving solutions, we stand by our guarantees.
