Heat Recovery Ventilation System (HRV)

A balanced ventilation system introduces fresh outdoor air into a home at the same rate that stale indoor air is exhausted from the home. Energy Recovery Ventilation (ERVs) and Heat Recovery Ventilation (HRVs) are similar devices in that both supply air to the home and exhaust sale air while recovering energy from the exhaust air in the process.

To Qualify For Rebates:

  • Home should be at or below 0.35 Natural Air Changes per Hour (NACH); if not, air sealing must be
    done before or in conjunction with ventilation project
  • Ventilation unit is required to deliver fresh (supply) air to main living/work space and each
    bedroom/office, at a minimum
  • Installation location allows for service and filter maintenance
  • All ductwork must be sealed and insulated, or located in a conditioned space
  • Equipment must meet all of the following:
    • SRE (Sensible Recovery Efficiency) at 70% or higher
    • Electrically commuted motors (ECMs)
    • Cold climate tested, demonstrated operation to -13°F

Residential Air Source Heat Pump

Heat pumps offer an energy-efficient alternative to furnaces and air conditioners for all climates. Like your refrigerator, heat pumps use electricity to transfer heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. Because they transfer heat rather than generate heat, heat pumps can efficiently provide comfortable temperatures for your home year-round.

Ductless, mini-split-system heat pumps (mini-splits) make good retrofit add-ons to houses with “non-ducted” heating systems, such as hydronic (hot water heat), radiant panels, and space heaters (wood, kerosene, propane). They can also be a good choice for room additions where extending or installing distribution ductwork is not feasible.

Like standard air-source heat pumps, mini-splits have two main components — an outdoor compressor/condenser and an indoor air-handling unit.

Cold Climate Air, Water, or Ground Source Heat Pump (heating and cooling)
• Must be “cold climate” rated to -5°F or colder minimum (Eagle County=Climate Zone 6)
• Minimum Coefficient of Performance (COP) @ 5°F of 1.75
• Air Source Heat Pumps Heating Seasonal Performance Factor minimums:
o Ducted HSPF2 of 8.1 or HSPF of 9.6
o Ductless mini-split HSPF2 of 9.5 or HSPF of 11.0
• Outside unit must be elevated at least 12 inches off the ground to defrost properly
• Recommended:
o load calculation to right size heat pump system and derate for high elevation
o heat pump provides majority of heating load (+/- 80%)

In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical house, however, about 20-30% of the air that moves through the duct system is lost to leaks, holes, and poorly connected ducts. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set. More about duct sealing…

To Qualify for Rebates:

  • Repair any damaged and disconnected ducts and straighten out flexible ducts that are tangled or
  •  Seal all leaks and connections with mastic, metal tape, or an aerosol-based sealant
  • Seal all registers and grills tightly to the ducts
  • Before and after CFM measurements for ducts required
  • Insulate ducts to R-6 or higher in unconditioned areas (attics/crawlspaces/garages)
  •  Recommend evaluating your system’s supply & return air balance, to ensure air return ducts not
    too small
  • Recommend including a new filter as part of any duct system improvement
  • Recommend if you have combustion appliances that you ensure there is no back drafting by
    getting a CAZ (combustion appliance zone) safety test after ducts are sealed

Diagram of a heat pump clothes dryer

A heat pump dryer works as a closed-loop system by heating the air using it to remove moisture from the clothes. They are easy to install since they don’t require ventilation and can reduce energy use by at least 28% compared to standard dryers. They also dry laundry at low temperatures, so they are gentler on clothes. More…

Heat Pump Water Heaters can save a household of 4 approximately $350 per year on its electric bills compared to a standard electric water heater and up to $3,750 over the HPWH’s lifetime. Larger families — that typically use more hot water — will save even more! More…

To Qualify For Rebates:

Air leakage occurs when outside air enters and conditioned air leaves a building through cracks and openings in the building envelope (building envelope is the separation of the interior and exterior of a building). Air sealing limits this unintentional air movement by sealing all joints, penetrations, and other openings.

To Qualify For Rebates:

  • Pre- and post-blower door assessment required
  • Air leakage must be reduced by 10% or more as measured in CFM50 by blower door test
  • If at/or below 0.35 NACH before or after improvement, you are required to meet with an Energy
    Coach at Walking Mountains to understand opportunities for fresh air ventilation, and identify
    existing ventilation present in the hom

Insulation in your building provides resistance to heat flow and lowers your heating and cooling costs. Properly insulating your building not only reduces heating and cooling costs, but also improves comfort. More…

To Qualify For Rebates:

  • Air sealing must be completed prior to adding insulation unless Natural Air Changes per Hour
    (NACH) is 0.35 or lower
  • Pre- and post-blower door assessment required
  • Must reach the following R-values/details:
    •  Exterior Wall: Insulate exterior/foundation walls to minimum R-19
    • Attic: Insulate floor of unfinished attic to minimum R-60
    •  Floor: Insulate floor of living space above garage/unconditioned crawl to min R-30

By trapping air in the cells of these shades they insulate you windows and minimize the loss of heated or cooled air from inside, which may improve the thermal performance of your home

Auditing your building’s energy usage is the first step to building a solid plan for improving energy efficiency.

An ASHRAE Level II audit begins with a Level I audit but takes the data collection and final reporting a step farther and includes more detailed energy calculations and financial analysis of proposed energy efficiency measures.

An ASHRAE Level III audit is an engineering analysis focusing on potential capital-intensive projects. It provides detailed cost and savings calculations required for major capital investment decisions.

To Qualify For Rebates:

  •  Report must be provided to Walking Mountains
  • Must provide contractor’s modeling for potential energy savings
  • Must adjust controls as determined by contractor and provide proof
  • Rebate only available for an initial report, updated reports do not qualify

A variable frequency drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage of its power supply.

To Qualify For Rebates:

  • Replace single speed motor/pump with VFD

Variable refrigerant flow systems can simultaneously heat and cool different parts of a building. These systems can be very efficient because they can take waste heat captured in one part of the building (e.g. a server room, or the side of the building exposed to direct sunlight) and deliver it to spaces requiring heat.

To Qualify For Rebates:

  • Energy Efficiency Ratio (EER) 10+
  • Coefficient of Performance (COP) 2+
  • VRF must be used as the primary heating and/or cooling source

You can save money on your heating and cooling bills by simply resetting your thermostat when you are asleep or away from home. You can do this automatically without sacrificing comfort by installing a programmable thermostat. More…
