The Rexburg Idaho LDS Temple

Viewed as one of the most exquisite buildings in North America, the Rexburg Idaho LDS Temple is a major icon in the small town of Rexburg and Eastern Idaho. Mountain West Mechanical was part of the construction team, installing all the plumbing, hydronics and wet side HVAC systems. This system was very complex to design and install and the crew at Mountain West Mechanical is proud to be able to place this architectural treasure as one of our many successes.

The Teton Radiology Center is located in Rexburg Idaho and is declared to be one of the most energy efficient buildings in North America, as far as the HVAC system is concerned.

The building was completed in the spring of 2009. Mountain West Mechanical Inc. was the HVAC and plumbing contractor for this project, redesigning the original HVAC system to better serve the needs of the facility and saving nearly $150,000.00 in up front costs to the facility.

The HVAC system consists of four Daikin Variable Refrigerant Volume (VRV) III inverter heat recovery units.(Inverter Heat Recovery units allow for simultaneous cooling and heating from one system). Accompanying the VRV III units are five multi-split heat pumps which gives the facility added controls for specific mechanical rooms (MRI mechanical room and ct scan mechanical rooms) which require special temperature requirements.

Teton Radiology Air ConditioningTeton Radiology Air Conditioning
The mechanical room which this equipment is stored in is equipped with adjustable louvers in the north and west walls. These louvers control the amount of fresh air needed to operate the heat pumps in normal weather conditions. In the coldest winter months the louvers can be closed and interior vents opened so the warm exhaust air from the VRV III units can be re-circulated within the mechanical room, thus reducing energy consumption.

The system is controlled by Daikin’s iTouch Controller.

This controller has several powerful functions:

  • Centralized control with 3 different view styles
  • Group and zone control capabilities
  • Weekly schedule with yearly calendar
  • Set-point range restriction
  • Temperature limit settings
  • Alarm E-mail which monitors and sends alerts of system issues or power outages
  • Web browser application which allows monitoring and adjustments via a web browser

Daikin’s VRV III system is the 7th generation of the original Daikin VRV® launched in 1982. Completely re-engineered to realize opportunities for VRV in taller / larger buildings, it utilizes the latest advances in refrigeration and air-conditioning technology. The totally new Daikin Inverter compressor system delivers improved efficiency and performance, while ensuring satisfaction of demands throughout connected zones across the complete operation cycle. With a choice of Heat Recovery 460V/3Ph/60Hz or 208-230V/3Ph/60Hz, the system configurations power up to 20-Ton capacity from a single piping network. The system also allows up to 41 indoor fan coil units, a 200% connection index, and integrated controls, with BMS options and piping limitations never before seen with a DX system. With these attributes, VRV III naturally positions itself wherever traditional chilled water systems are desired.

Daikin’s strong product line up (VRV, Skyair, Mini-split, Multi-split) can be installed in any project. Whether its your home or business, Mountain West Mechanical can make it happen.

Example of How this might work

The cost of a Daikin two-room ductless heat pump will range from $4,000 – $5,000 depending on installation difficulty.
If you qualify for the rebate and the tax credit it may look like this:

Example
Total Cost $5,000
Less Rebate -1,250
After Rebate $3,750
Federal Tax Credit -1,500
Total Cost to You $2,250

IDAHO FALLS POWER HEATING COSTS VS. INTERMOUNTAIN GAS HEATING COSTS

FEBRUARY 2007

ASSUME 300 THERMS OF GAS USAGE IN ONE MONTH FOR A LARGER HOME.

HEAT INPUT INTO THE HOUSE = 300 THERMS X 90% EFFICIENCY = 270 THERMS USED TO OFFSET HEAT LOSS IN THE HOUSE.

COST OF GAS FOR ABOVE IS 300 THERMS X $1.03285/THERM = $309.85/MO.

DAIKIN VRV-S HEATING SYSTEM ELECTRIC UTILITY COSTS FOR SAME HEATING INPUT INTO THE HOUSE USING IDAHO FALLS POWER SCHEDULE 1.

270 THERMS = 7,911 KWH.

DAIKIN VRV HEATING SYSTEM WITH A 2.866 COP AT 5.5 F OUTSIDE TEMPERATURE USES 7,911 KWH/2.866 = 2,760 KWH/MO.

COST OF ELECTRICITY = 2,760 KWH X $0.0575/KHW = $158.70/MO.

DAIKIN VRV HEATING COST IS 51% OF A 90% EFFICIENT GAS FURNACE, SAVING 49%.

NOTE: SAVINGS ARE LARGER WHEN IT IS WARMER THAN 5.5 F OUTSIDE AIR TEMPERATURE. COP USED IS AT 5.5 F.

June 18, 2009

ASSUME MULTI-SPLIT SYSTEM WITH 22,000 BTUH HEATING AVAILABLE IN UNIT WITH AN AVERAGE OF 13,500 BTUH LOAD.

NATURAL GAS………

TOTAL BTU’S CONSUMED PER MONTH IS:
13,500 X 30 DAYS X 24HRS/DAY = 97.2 THERMS.

GAS HEATING COST PER MONTH IS:
97.2 THERMS/0.80 EFF. X $1.06962/THERM = $129.96/MO.

SERVICE CHARGE, PER MONTH = $6.50

TOTAL GAS CHARGE = $135.96/MO.

ELECTRIC MULTI-SPLIT HEATING UTILITY COST BASED ON IDAHO POWER SCHEDULE 1

97.2 THERMS = 2,848 kWh

Daikin’s™ VRV-S system provided the contractor with an easy installation…
the project needed sustainable products for a LEED certification…
and the homeowners with an energy efficient heating and cooling system.

Daikin AC recently donated a VRV-S system to a deserving family selected to receive a newly constructed home that will be featured on the reality television show, “Extreme Makeover; Home Edition.”

The variable refrigerant volume heating and cooling system, donated by Daikin, consists of 2 outdoor units, VRV-S heat pumps and 4 ducted concealed ceiling units. The system will be controlled by 4 7-day programmable controllers.

“Daikin AC is proud to be a part of such a generous effort,”explained Christina Trondsen, Daikin AC’s director of marketing. “Daikin is dedicated to manufacturing products that are sustainable and energy efficient and we believe the deserving family will enjoy the absolute comfort as well as the lower costs associated with operating Daikin’s energy efficient products.”

The new home located in Geneva, New York, was built using sustainable products, including Daikin’s energy efficient heating and cooling systems. This residential project will aim for a LEED Gold certification. LEED, which stands for Leadership in Energy and Environmental Design, is a rating system developed by the US Green Building Council that measures sustainable elements of a building. LEED has been around for many years for commercial construction projects, but is relatively new for residential construction projects. The rating system has four categories of certification: Certified, Silver, Gold, and Platinum.

“The Daikin equipment is as efficient as a geothermal heat pump system but with better temperature and dehumidification control capability, “explained Ellis Guiles, P.E., HERS (Home Energy Rating System) rater and director of sales and marketing for TAG Mechanical. Guiles, who specified Daikin, knew to obtain the LEED certification they would need to incorporate an energy efficient heating and cooling system into the home.
“Daikin was an excellent choice for the project because it has excellent zoning capabilities and it is also less expensive to install than a geothermal system, “explained Guiles. “The flexibility of the product was also essential because the 3500 square foot home did not have many interior walls. The system was also very quick and easy to design and install which was very important since the entire home was built in just over 100 hours.”
Each episode of Extreme Makeover: Home Edition features a race against time involving a team of designers, contractors, and several hundred volunteers who have seven days to completely rebuild an entire house.

The Hill family was selected to receive a brand new home, enabling them to keep and improve their boxing gym for underprivileged teens. For over 10 years, Tim Hill has been training kids from the ages of 8 to 21 to box for free, and pays all expenses out of his pocket. Many of the kids are from broken and impoverished homes and Tim gives them a sense of pride and expert training that has made 3 Olympic hopefuls.
