Being Green and Bringing Balanced Ventilation System to Your Projects

WHY ERV RecoupAerator Green - Based on Passive House Standard

The Passive House Standard is the world’s highest energy efficiency standard. It drastically reduces the energy load required to operate a building—by as much as 90 percent compared to existing buildings.

Building to the Passive House Standard makes renewable energy systems become more affordable and practical. Significantly shrinking a building’s energy demand, will allow smaller and less expensive alternative energy systems to satisfy it’s needs. Therefore building to the standard is the best starting point for a net-zero project.

Passive House relies on principles that have been proven over the past 20 years, not on pie-in-the-sky technologies. Many of these principles, like airtight building envelopes and superinsulation, were originally developed in the 1970s right here in the United States and Canada. Passive House does not dictate an aesthetic; structures that meet the standard can be traditional, ultra-sleek modern, or anything in between.

Passive House can be applied to residential, commercial, institutional and industrial buildings, implementations, as well as retrofit scenarios. The common set of features and characteristics that a Passive House building delivers are:

  • Superb consistent comfort and indoor air quality
  • An airtight, superinsulated building envelope
  • High-performance windows – triple paned in most climates
  • Energy recovery ventilator – continuous exhausting of stale air, while capturing it’s temperature conditioning and recycling it into the incoming fresh air.

Based on requirements by Passive House, ERV RecoupAerator has been tested and qualifies to their standard for Passive House Ventilation (shown on following figure):

    Testimonies for ERV RecoupAerator

    “This is a brief note, simply to say that I think you are doing great work. The team you have assembled there, your pioneering efforts with ventilation efficiencies here in the US, are truly admirable. Some days it may seem like the headwinds are awfully strong - the resistance to intelligent, superior ventilation technologies. But change is happening, even if not as quickly as we'd like. With Timber Ridge, we are small residential design/ build firm. Since learning of your systems in the Passive House training, we have worked to convince every owner - whether committed to PH or not - to ventilate using your systems. We are awaiting delivery of our first Ultimate Air residential ERV from your team shortly, and we are specifying your ERV in each new home we design now.” - Rich Backus, Certified Passive House Consultant; Timber Ridge Craftsmen, Inc.

    “I wanted to write and thank you and your team for helping in the successful completion of the Center for Energy Efficient Design in Rocky Mount, Virginia. As the first US Passivhaus public school, we were tasked by the school board to use American made products and to push innovation and implementation of cutting edge building technologies. The services you provided were above and beyond my expectations and your knowledge and insight was invaluable. After 6 months in operations the unit is performing above expectations with efficiencies well above 90%!” - Adam Cohen, Structures Design/Build, LLC, Roanoke, VA.

    Appendix: Benefits of Balanced Ventilation System

    (source US EPA and Energy Star)
    The air within homes can become stale from moisture, odors, and pollutants that penetrate the home or are generated internally by human activity and out gassing from building materials and furnishings. A constant supply of fresh outdoor air can provide a greater assurance of good indoor air quality and improved comfort.

    In most buildings, ventilation is provided accidentally when air leaks through the building envelope. Accidental ventilation is unreliable because it is dependent on a pressure difference between indoor and outdoor spaces caused by temperature and wind variations. Too much fresh air often enters a house during cold weather causing uncomfortable drafts and high heating bills. Not enough fresh air may enter during mild weather which can lead to poor indoor air quality.

    Air leakage through the building envelope accounts for between 25 percent and 40 percent of the energy used for cooling in a typical building (more energy may be needed especially in Indonesia humid climate). Many new buildings are being sealed to reduce this energy use. Where tighter construction reduces air leakage and accidental ventilation, active ventilation systems may be needed to provide fresh air.

    This figure below shows how a balanced ventilation system works in a residential building. ERV is used to bring filtered and treated fresh air inside the home and exhaust stale air to remove odor and polluted indoor air. Balanced ventilation systems can be used safely with all types of heating and cooling equipment and ERV can be operated as efficient as running a single bulb

    Balanced ventilation systems can provide many benefits including:

    • Improved indoor air quality. Balanced ventilation systems supply fresh air while exhausting stale air at an equal rate in and out the buildings. This proactive approach to ventilation can result in improved indoor air quality.
    • Improved comfort. Green rated buildings with tight construction and balanced ventilation systems can have fewer drafts and a constant supply of outdoor air resulting in improved comfort.
    • Improved health. Stale air can cause health problems. It can be responsible for symptoms such as headaches, drowsiness, and respiratory problems. These symptoms are more common in buildings with poor ventilation and moisture control. Continuously providing fresh air can result in the improved health and well being of the occupants.
    • Lower utility bills. Less energy is consumed to operate ventilation systems than to cool excessive amounts of outdoor air that infiltrates leaky homes. Additional savings are captured when these systems are equipped with either a sensible or total heat exchanger. This can result in lower utility bills, making buildings less expensive to operate.
    • Improved resale position. Green rated buildings with balanced ventilation systems can provide the many impressive benefits listed including more comfortable buildings with better indoor air quality and lower utility bills. These benefits can translate into higher resale value.
