  • Hilton Garden Inn, Richardson TX
  • Hilton Garden Inn, Richardson TX
    • Equipment Overview:
      • 4 Story Hotel made with ICF construction
      • 153 Guest rooms featuring fir-down ducted model FXDQ
      • Simplified controllers
      • 3 I-Touch Controllers with web-enabled software
      • FXSQ used in lobby and conference rooms
      • 144 Tons of VRV Heat Pump & Heat Recovery
      • Condensing units on the ground in 3 different pods
      • AAON outside air unit used to introduce fresh air into the hallways and commons area, which created a positive pressure in the guest rooms
  • Installation Issues
    • Inconsistent & Untrained Help
    • Don’t assume Contractor has remembered everything from Training
    • Leaks, wiring (power & communication)
    • Trim charge was not calculated (VRV-II)
    • Sufficient leak testing was not performed
    • Allow for sufficient piping length after 90 (20”) and 40” after refnet to avoid turbulence and other piping guidelines – needed to design with headers
      • Estimated Cost Savings
          • $500/window, grill, PTAC sleeve savings
          • $75/room drapes (weighted) savings
          • Up to $1.80/sq ft rebates possible per The Federal Tax credit program (includes envelope, lighting and HVAC)
          • Electrical service requirement reduction possible from 7,500 amp to 3,000 amp, (includes the 30 amp PTAC circuit savings)
          • **Preliminary first cost: $725,000 or $5,034/ton (Installed, including AAON make-up air unit)
          • Uncalculated savings but feasible:
            • Access space around the PTAC
            • Air leakage
            • Moisture control (total room remodel every 30 months)
            • Noise abatement through the PTAC grill
            • Condensate drain savings on PTAC’s
    Hilton Garden Inn, Richardson TX
  • Welcome to EnergyWise Structures___ The Home of Ultra Energy Efficient Engineering.htm
    • The Hilton Garden Inn in Richardson, Texas with 86,401 square feet was engineered by EnergyWise and is saving over $6,000 per month! As a new construction project, we implemented the complete EnergyWise program resulting in an energy tax credit of $1.80 per square foot in addition to engineering an ultra energy efficient, healthy hotel. Typical hotels of similar footprint in the chain are averaging $9,504 per month in heating and cooling. The EnergyWise guarantee not to exceed is just $3,456, a savings of over $6,000 every month!

  • Biddeford City Hall, Maine 2x 8 ton VRV + 1x 3- ton VRV-S Primary Hot Water Coil Integration 2 x 8ton VRV H/P & 1 x 4ton VRV-s Ambient temperature sensor (left) & thermostat tied in ABC terminals Hot water coils connected with indoor units Boiler system for hot water coils and other radiator heaters Zone valve for hot water coil controlled by KRP1B
    • New Construction (interior is under construction)
    • Installed the VRV-s system as both cooling and heating systems
    • To save energy cost, the VRV heat pump system will be used as long as possible. Fuel cost is getting higher.
      • Ambient thermostat that is set setpoint as 20F will lockout heat pump
      • It also kick on heat pump with a suitable differential (+10F?)
    • The zone valve for the hot water coil is controlled by the KRP1B adapter that is installed in the indoor unit.
      • While heat pump is locked out, the valve is controlled as a primary heater. (+/- 1F basis)
      • Otherwise in the heating mode, it is controlled as an AUX heater. (7.2F differential basis)
      • 7.2F basis might work well if heat pump lock out temperature, 20F, is suitable for this project; this means that the heat pump can afford to heat up 7.2F temperature differences.
    • The end switch, it will be on when the valve fully opens, on the zone valve kicks on the boiler. And boiler circulate the hot water and maintain its temperature.
    • Lennox ducted split system with hot water coil that controls three zone dampers is also installed. This system covers lower side of the house and the VRV system covers upper side.
      • If we had the residential AHU, we could cover this parts. The zoning might be crucial though.

  • Hot water Boiler Zone #1 Zone Valve Ambient Thermostat KRP1B Zone Valve Zone #2 Zone #3 Floor Radiant Heater for bathrooms Below 20F, BC terminal on the outdoor unit PCB is shorted One of the end switches kicks on the boiler Hot water coil Indoor unit Zone valve Zone valves for Floor Radiant Heater Hot water coil Indoor unit Boiler Room in the attic Mechanical closet in the room CS #3 (cont’d) Boiler circulates hot water and, heats it up instantly
    • Added the VRV-s system as a cooling system
    • As for heating, there is the existing hot water system, perimeter radiators.
    • There is no ceiling, so that wall mounted indoor unit (FXAQ) are preferable.
    • The ducted indoor unit (FXSQ) is installed in the basement that is combined with the existing AHU for living room.
      • While the FXSQ fan is running, the AHU fan also runs with the fan status of KRP1B.
      • While heating mode, hot water zone valve is controlled by heater status of KRP1B
      • Heat pump is always locked out.
    • Programmable controller (Euro Remote) is installed for FXSQ. The AWAY function keeps the living room above 50F.
