IS WATERFURNACE A SMART SOLUTION FOR A SCHOOL?
Water source/Geothermal heat pumps are the smartest choices for today's schools. They lower operating costs, and in most cases lower installation costs while creating a comfortable and quiet learning environment. Individual zone control and unmatched system reliability are added benefits that are hard to ignore. Water source/Geothermal systems are easily scalable to apply to a small elementary school, a larger regional high school, or a multi-building campus.

Water source/geothermal system installations can eliminate many common issues in school HVAC systems such as:

· No large-scale complex duct work

· No complicated controls

· No chillers or Boilers

· No holes in exterior walls

· No staff operating engineers required

· No large mechanical rooms

CHOOSING THE SOURCE ENERGY OPTION?
There are many different source installation options available to both new construction and retrofit job sites ranging from traditional water loop heat pump with boiler and cooling tower to geothermal options. All geothermal options feature ground loops that will last for more than 50 years providing the same high efficiency for subsequent equipment. All of these closed piping system applications also provide heat recovery capability. The ability to move heat from core building areas in cooling to perimeter areas requiring heat is a fundamental benefit of water source heat pumps no matter the source energy type. (See page 12 for details on heat recovery).

FIRST COST ECONOMICS
WSHP/Geothermal systems may not be as expensive to install as you think, most systems have installed costs similar to conventional systems. Most systems will show payback in less than 24 months. WSHP/Geothermal systems have the advantage of a smaller geothermal loop and a smaller tower that only operates in the summer months reducing both installed and maintenance costs while maintaining high efficiency. Geothermal systems also have the advantage of a federal tax credit that can be applied in many situations.

No toxic refrigerant is pumped throughout the building as with VRF systems.

No chemicals associated with the prevention of scaling and bacterial growth are needed.

No year-round tower operation or boiler maintenance (geothermal systems only).

Lowest maintenance costs ASHRAE shows Geothermal having the lowest maintenance costs of any HVAC systems.

LOWER INSTALLATION COSTS WITH A ZONING SYSTEM
Zoning can reduce number of units and provide accurate temperature conditioning in offices and smaller rooms in the school. For instance a BACnet Zoning system on a WaterFurnace WSHP can maintain accurate zone temperatures at a reduced installed cost by allowing a 6 ton variable speed unit to supply up to 6 smaller zones, instead of 3 or 4 units supplying those same 6 zones. Single unit piping and electrical also add to the savings and changing only one filter reduces your maintenance costs as well! Up to 6 zones (400-800 ft2 zone) would have a single compressor bearing unit providing direct heating and cooling to each zone with its own thermostat control. No large complicated air delivery systems to overcool or under deliver air. This is especially useful when rooms with differing loads are required to be combined in a single unit such as 2 offices and a conference room. Each zone will have its own thermostat independent control.

OTHER BENEFITS OF CHOOSING WATERFURNACE
1. LARGE AREA SOLUTIONS: TWINNING LARGE VS WSHP
Large tonnage water source equipment can be accomplished by the twinning of our large (10 & 15 ton) Variable Speed Versatec UV by twinning the units. From 2- 8 individual units can be combined into one large wshp (20-60 tons). In this configuration onsite installation costs are reduced and all heat pumps can be controlled using a single control signal with several options for staging.

2. QUIET OPERATION IN A LEARNING ENVIRONMENT
The generally smaller compressors and blowers of WSHP's can provide accurate comfort and low noise levels. With typical application details, NC levels of <35 are achievable in most applications. Locating units in the hallway and conditioning the classrooms through ductwork allows servicing during class time and reducing any noise transmission to the classroom or disruption. For more information on WaterFurnace equipment and sound testing, see our Sound Application Guides on our website.

3. CAN YOU RETROFIT WITH WATERFURNACE? SMALLER FOOTPRINT = EASY REPLACEMENT
If your school already has WSHP's, it is likely the existing units have been encircled with plumbing, ductwork and electrical lines. Replacing these units at end of life can be difficult since newer more efficient models are larger and will not fit in the existing space. Re-routing the electrical and plumbing can be very expensive. The WaterFurnace Versatec Compact has 21st century WSHP efficiency in the footprint of the older much less efficient models. For example, our 3 ton UBH Series unit is a full 12 inches shorter than our nearest competition and outperforms it in efficiency as well.

4. LARGE AREA SOLUTIONS: ROOFTOPS
A rooftop unit (3-30 tons) can be located on the roof for conditioning larger areas such as cafeterias, auditoriums and gymnasiums without the need for large mechanical rooms or expensive hanging equipment. The 30% fresh air capability of the optional economizer frequently satisfies all ventilation requirements negating the need for a separate DOAS unit. Rooftops are also suitable for classroom use as a unit ventilator replacement.
5. VENTILATION AIR EQUIPMENT
The Versatec Packaged Rooftop with integrated economizer features a 4 Mode temperature or enthalpy control within a single control integration and is ASHRAE 90.1-2013 compliant. The economizer can also be engaged directly through network commands. All economizer network points are communicated to the BAS system for a fully integrated control with fault detection. The system uses high accuracy and factory calibrated enthalpy sensors and the dampers are California Title 24 Class 1A tip sealed for air tightness.

EDUCATIONAL COMFORT SOLUTIONS WHAT IS HEAT RECOVERY?
A hallmark feature of the water source/geothermal heat pump is the ability to move heat from the center core of the building where air conditioning occurs most of the year to the perimeter zones that need heat in the morning startup or winter months. This `heat recovery' can add significant savings to the building energy costs and is inherent in every WaterFurnace WSHP system.
HEAT RECOVERY: CHILLER FOR HOT WATER
Adding a WaterFurnace Envision2 NXW to generate hot water from waste heat in the building loop is an excellent energy saving idea. The chiller generates 130°F hot water while simultaneous removing heat from the building loop improving the overall efficiency of the WSHP system and generating hot water at COP's of over 4-5.
