Methods for Properly Ventilating an Airtight House
Now, you must be wondering how to ventilate your house, particularly one that is airtight. Specific techniques and ventilation ideas can make all the difference. Below are a few of the most practical methods:
1. Use Mechanical Ventilation Systems
One of the most helpful ways to ventilate an airtight home is to use a mechanical home ventilation system. Mechanical ventilation systems are tailored to spread air efficiently all over your house.
The systems work by pulling in clean air from the outline while throwing out old air from the house. This assists in extracting pollutants and sustaining healthy indoor air quality. Mechanical ventilation is typically available in different types, including ventilation fans, balanced ventilation systems, heat recovery ventilators (HRVs), or energy recovery ventilators (ERVs).
Every kind has its own benefits and drawbacks, so it's important to select the one that best fits your home’s budget and preferences.
You can choose from several types like:
Supply Ventilation Systems: Introduce fresh air into the house.
Exhaust Ventilation Systems: Expel indoor air to the outdoors.
Balanced Ventilation Systems: Bring fresh air in while expelling stale air, maintaining a balanced flow.
Although there’s not enough evidence on when to install a mechanical ventilation system in a house. But there’s some agreement that if the home is attaining below 3 to 7 air changes in an hour at 50 pascals (Pa) mechanical ventilation should be installed.
This proactive strategy for ventilation makes sure that clean air arrives in your home constantly, to remove pollutants and moisture. When it comes to ventilation for airtight homes, mechanical systems are highly effective.
2. Install Heat Recovery Ventilators (HRVs) or Energy Recovery Ventilators (ERVs)
Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs) are innovative ventilation systems, that are very energy-efficient and can aid in keeping up your home’s energy efficiency while enhancing ventilation.
This is a great choice for airtight homes. These systems retrieve heat from the outgoing air and move it to the incoming air, lowering the energy required to chill or heat your home.
The chief difference between HRVs and ERVs is the way they interchange heat. HRVs utilize a heat exchanger to shift heat between the incoming and outgoing air drifts, and ERVs use a desiccant wheel to soak up dampness from the outgoing air and secret it into the incoming air.
HRVs: Ideal for homes in colder climates, where heat needs to be retained.
ERVs: Better suited for warmer and more humid areas, as they also transfer moisture to balance humidity levels.
These ventilation systems make sure that clean air gets into your home without disturbing energy savings, making them one of the perfect alternatives to improve ventilation in house.
3. Use Exhaust Fans in High-Moisture Areas (Bathrooms, Kitchens, and Laundry Rooms)
Exhaust fans are required to remove moisture and prevent mold formation in high-humidity spaces such as kitchens, bathrooms, and laundry rooms. Running exhaust fans in these areas helps sustain indoor air quality, extract humid air, smells, and toxins and put a stop to issues like mold and mildew.
The best places to use are:
Bathroom Exhaust Fans: To get rid of dampness after hot showers.
Kitchen Range Hoods: To remove smoke, steam, and cooking smells.
Laundry Room Fans: To take out humidity created during drying and washing.
4. Ventilate Crawl Spaces and Basements
Crawl spaces and basements can be the origins of moisture and mold issues as they are mostly abandoned and badly ventilated. By offering proper ventilation to these spaces, you can take a step to avoid moisture growth and enhance overall indoor air quality.
For this, you require innovative tools _ a ventilation fan like the Alorair 720CFM Crawl Space Ventilation Fan particularly made for these areas. These tools can make a big difference in air circulation, reducing dampness, preventing mold, and ensuring your stored objects are secure from damage.
Moreover, coupling a ventilation fan with a dehumidifier can improve moisture control in these often confined spaces.
Whether you want a sophisticated ventilation fan or an energy-efficient dehumidifier for crawl spaces and basements, AlorAir Crawlspace excels in designing high-quality products.
Common Challenges of Ventilating Airtight Houses
One of the major challenges of ventilating an airtight house are following:
Finding the Right Place
The main issue while ventilating is finding the right place between energy efficiency and sufficient air interchange. Although airtight buildings help lower heat loss, it can also make it complicated to clear out contaminants and sustain healthy indoor air quality.
Energy Efficiency Loss
Drawing in clean air can cause energy loss if not controlled properly. You need to sweet spot between clean air and the energy loss that will occur.
Cost of Installation and Maintenance
Some systems like mechanical ventilation systems and exhaust fans could demand beforehand investment and constant maintenance.
Balancing Humidity Levels
Maintaining the proper balance between too little and too much humidity can turn complex. These challenges can be addressed by choosing the right home ventilation system tailored to your specific needs.
