BENEFITS OF INCREASED VENTILATION

• ❤️ BETTER HEALTH
• ? REDUCED VIRAL SPREAD
• ? IMPROVED COGNITIVE FUNCTION
• ? INCREASED PRODUCTIVITY

INDOOR AIR QUALITY MATTERS

Deficient indoor air quality (IAQ) is a significant threat, as modern, tightly sealed buildings can trap contaminants like off-gassing materials, humidity, mold, odors, cooking fumes, CO2, and fibers. This can negatively impact occupant health, cognitive function, building structures, and financial outcomes. People spend approximately 90% of their time indoors, where indoor air can be two to five times, and sometimes up to 100 times, more polluted than outdoor air. The EPA ranks indoor air pollution as a top-five health risk.

Children and seniors are particularly vulnerable to deficient IAQ due to weaker immune systems. Children, in particular, inhale more pollutants proportionally and have narrower airways.

ADVERSE EFFECTS OF DEFICIENT IAQ

• HEALTH PROBLEMS: Allergies, headaches, coughs, asthma, skin irritations, breathing difficulties, and potentially cancer, liver disease, kidney damage, and nervous-system failure.
• DISEASE TRANSMISSION: Ventilation with outdoor air is crucial for diluting airborne contaminants and reducing disease transmission rates.
• COGNITIVE IMPAIRMENT: Elevated CO2 levels, common indoors, have been shown to negatively impact thinking and decision-making.
• REDUCED PRODUCTIVITY: Deficient IAQ can lead to significant costs associated with decreased worker performance and increased sick time.

REDUCE INDOOR AIR CONTAMINANTS

1. Contaminated Airborne Aerosols: Aerosols generated by coughing, sneezing, talking, and breathing can carry viruses and bacteria.

2. Humidity: From exhaled breath, water sources (faucets, showers, leaks, floods).

3. Carbon Dioxide: A constituent of exhaled breath.

4. Formaldehyde: Off-gassed from adhesives, fabric treatments, stains, varnishes.

5. Odors: From bathrooms, kitchens, dry-erase markers, occupants, and pets.

6. Tobacco smoke: From smoking areas close to building entrances.

7. Phthalates: Off-gassed from adhesives, vinyl flooring, wood finishes, plastic plumbing pipes, and other building materials.

8. VOCs, toxic gases, vapors: Off-gassed from furniture, carpets, paints, cleaners, solvents, glues, and building materials.

9. Ozone: Off-gassed from copiers, electrostatic air cleaners, and other office equipment.

REDUCE ENERGY COSTS AND IMPROVE IAQ AT HOME

The most effective solution for cleaner and healthier indoor air is increased and balanced ventilation. By introducing sufficient controlled, filtered outdoor air and exhausting equal parts of stale indoor air, IAQ is significantly enhanced.

TYPES OF HOME VENTILATION

THE BEST SOLUTION: RenewAire's energy recovery ventilation (ERV) technology offers enhanced IAQ, superior ventilation efficiency, and significant energy cost savings.

BETTER HEALTH + LOWER BILLS = INCREASED VENTILATION VIA ERVS

The American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) 62.2 standard establishes residential ventilation requirements to ensure indoor air quality and occupant health. ERVs help meet these standards while reducing energy costs.

OPTIMIZE ENERGY EFFICIENCY IN EVERY SPACE

RenewAire ERVs are a sustainable ventilation solution. Our static-plate, cross-flow core separates outgoing, polluted indoor airstreams from incoming fresh airstreams while transferring total energy (heat and water vapor). Airstreams do not mix, and pollutants are not transferred across partition plates.

COMMERCIAL ERVS

The RenewAire HE and LE Series Commercial ERVs offer simplicity, flexibility, reliability, and efficiency for all commercial applications. These units maximize energy efficiency, allow for downsizing of HVAC equipment, and reduce costs.

• HE SERIES: Packaged solutions, indoor/outdoor, 120-8,800 CFM.
• LE SERIES: Large capacity, indoor/outdoor, 1,500-11,000 CFM.

DOAS SYSTEMS

Dedicated Outdoor Air Systems (DOAS) deliver 100% outside air to occupied spaces, often incorporating energy recovery as required by codes like ASHRAE Standard 90.1 and IECC, which mandate a minimum of 50% total effectiveness for energy recovery components. Even when not mandated, energy recovery is a key method for improving building energy efficiency.

APPLIED ERVS

RenewAire's CA, PA, and SA Series Applied ERVs provide flexibility, efficiency, and numerous application possibilities.

• SUMMER: Warm, humid outdoor air is precooled and dehumidified by outgoing cool interior air.
• WINTER: Cold, dry outdoor air is preheated and humidified by outgoing warm interior air.

WHY ENERGY RECOVERY IS CRITICAL

DECARBONIZATION AND ENERGY EFFICIENCY DEMANDS: 100% outdoor air units handle significant heating and cooling loads. Energy recovery minimizes these loads and the required HVAC equipment.

ASHRAE 90.1-2010 mandates energy recovery based on supply airflow, outdoor air percentage, geographic location, and hours of operation, requiring a minimum total effectiveness of 50%. Energy recovery device effectiveness varies by type, material, and airflow balance, determined by AHRI Standard 1060 test procedures.

Map of Climate Zones: The US is divided into climate zones (1-8) based on temperature and humidity, influencing energy recovery requirements.

PERCENTAGE OF OUTDOOR AIR AT FULL DESIGN AIRFLOW RATE (CFM)
