-HVAC Systems:

Water-cooled Heat Pump- Pros: Lowest energy consumption, low maintenance on geo-thermal wells Cons: High installation cost (short term), high maintenance on compressors (long term), compressor noise

Water-cooled Chillers- Pros: Low energy consumption, longest system life Cons: High installation cost, easily damaged, large mechanical space, and requires outdoor space for cooling tower, high maintenance for cooling tower Air-cooled Chillers- Pros: Moderate energy consumption, moderate installation cost, moderate system life Cons: Large/noisy chillers located outside Gas-fired hot water- Pros: Lowest energy cost, moderate maintenance cost, long service life Cons: Highest installation cost Electric resistance coils- Pros: Lowest installation cost, low maintenance cost, moderate service life Cons: Highest energy consumption
