Installation Issues Inconsistent & Untrained HelpDon’t assume Contractor has remembered
everything from TrainingLeaks, wiring (power & communication)Trim charge was not calculated (VRV-II)Sufficient leak testing was not performedAllow 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

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!

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.
