Why Indoor Air Quality Matters and How to Improve It

For years, fiberglass batt insulation was the only way to insulate walls. Today’s construction technology has many other options!

The excitement of building a new home often focuses on choosing countertops and paint colors, but there’s something equally important you can’t see: your indoor air quality (IAQ). With Americans spending approximately 90% of their time indoors, the quality of our indoor environment has never been more crucial for our health and well-being. Let’s explore why IAQ matters and how to create a healthy indoor environment in the home you’re building from day one.

Why Indoor Air Quality Matters in New Construction

Maryland’s climate, with its characteristic humidity and seasonal allergens, can intensify these issues. For families with older adults, young children, or members with existing health conditions, maintaining good IAQ becomes even more critical, as these groups are particularly vulnerable to indoor air pollution.

That “new home smell” many people love? Unfortunately, it’s often a sign of volatile organic compounds (VOCs) being released from building materials and finishes. These chemicals can have both short term and long-term health impacts that might not be immediately apparent.

Many manufacturers are working to eliminate harmful chemicals from their products. For example, fiberglass insulation was often made with asbestos or formaldehyde in years past but is now manufactured without either harmful chemical. Other insulations, such as cellulose insulation, are made from eco-friendly products like recycled paper and treated with boric acid, a common chemical found in many eye drops.

Sources of Indoor Air Pollutants in New Homes

Understanding where pollutants indoors come from is crucial for prevention. Building materials like paints, adhesives, and composite wood products can release harmful chemicals into your indoor environment. Improperly installed HVAC systems may also circulate both indoor and outdoor air pollutants throughout your home project.

Another significant concern is carbon monoxide from combustion appliances, which requires proper ventilation to maintain safe indoor and outdoor air exchange. Additionally, Maryland homes face potential exposure to radon gas, a naturally occurring radioactive gas that can affect outdoor air quality and seep into homes through foundation cracks.

Strategies for Building a Healthy Home

Material Selection

Start with choosing low-VOC paints, adhesives, and flooring materials. When selecting insulation, consider options like cellulose insulation, which offers excellent performance without harmful chemical binders. Natural materials generally contribute to better indoor air quality.

Proper Ventilation

Improving ventilation is also essential for maintaining healthy indoor air. Install an effective ventilation system that includes heat recovery ventilators (HRVs) to efficiently exchange stale indoor air with fresh outdoor air. Pay special attention to moisture-prone areas like bathrooms and kitchens to prevent mold growth.

Air Sealing and Insulation

Create a tight building envelope through proper air sealing, preventing unwanted air infiltration while controlling moisture. Quality insulation plays a crucial role in this process, with options like spray foam providing excellent air-sealing properties.

HVAC System Design and Installation

Work with qualified contractors to design and install an HVAC system that provides adequate filtration and ventilation. Consider using high-efficiency filters to remove smaller particles.

Moisture Control

Implement proper drainage and vapor barriers during construction to prevent future moisture problems that could lead to mold growth.

Radon Mitigation

If radon is a concern in your area, it’s important to incorporate radon-resistant construction techniques and consider installing a radon mitigation system to ensure you build a radon-resistant home.

Beyond Construction: Maintaining Healthy Indoor Air

Post-construction cleanup is crucial for removing construction dust and debris. Encourage future homeowners to establish a regular maintenance schedule for their HVAC system, including filter replacements, to ensure clean and efficient airflow. Practice source control by using low-VOC cleaning products and maintaining appropriate humidity levels to discourage mold and dust mites.

Four Easy Steps to Better Insulation in a New Maryland Home

When undergoing new construction there’s a solution that will maximize your new home or business project’s energy…

Updated April 2024

Professional Insulation Contractor in Baltimore, MDMaryland offers its residents a delightful mix of urban sophistication and natural beauty, but within this charm lies a challenge that every Maryland resident knows too well–the unpredictable weather. From scorching summers to chilly winters, the temperature swings can be discomforting, not to mention the toll they take on your wallet through high energy bills. But don’t worry, when undergoing new construction there’s a solution that will maximize your new home or business project’s energy efficiency and keep future owners’ energy expenses under control: proper insulation.

We’ve compiled four straightforward steps you can take to ensure your new construction project is insulated properly from the start.

Sealing the Cracks: Battling Air Leaks

Often, newly constructed homes and businesses are full of sneaky air leaks around many areas including windows, doors, and attic hatches. These small gaps are major culprits of energy loss, but thankfully there’s a simple remedy. With a bit of caulking, weatherstripping, or can foam insulation, you can air seal those gaps tight, banishing the drafts and keeping heating and cooling where it belongs–inside the building.

Elevating the Attic: The Key to Temperature Control

The attic, often overlooked but oh-so-important, holds the key to maintaining a comfortable living environment year-round. In winter, it’s a prime spot for heat loss, while in summer, it becomes a magnet for unwanted heat gain. The solution? Attic insulation. Whether choosing the timeless classic fiberglass batts or opting for the efficiency of spray foam insulation, investing in your building project’s attic insulation during construction will pay dividends many times over for future residents in both comfort and energy savings.

Fortifying the Walls: Battling the Elements

Depending on the construction of your home or business project, your walls may need some extra TLC in the form of insulation. Loose fill cellulose or fiberglass insulation are popular choices for existing walls, offering effective protection against heat loss and ensuring a snug living or working space regardless of the weather outside. Wall insulation also helps with lessening exterior sounds, giving occupants a more peaceful interior.

Seeking Professional Guidance: When to Call in the Experts

A reputable, licensed insulation contractor in Maryland, such as DeVere Insulation, can assess your building project’s specific needs and recommend the most effective insulation solutions, ensuring that your investment in new home insulation pays off for years to come.

Plus, an insulation professional will be well versed in Maryland’s energy codes and required insulation levels for new homes and businesses. Maryland’s energy code calls for the following amounts of insulation to be installed in buildings:

Ceilings: R-49
Walls: R-21
Floors: R-30
Basement Walls: R-13

These numbers can be confusing but remember, R-value represents insulation’s thermal resistance value, and the required R-value is the amount of insulation needed for our climate zone. When choosing a professional, it’s important to find one that pays special attention to not just meeting these energy codes, but also optimizing your new home or business building project’s energy efficiency.

The Rewards of Insulation: Beyond Comfort and Savings

The benefits of properly insulating your new home or business construction project extend far beyond mere comfort and savings on energy bills. By ensuring your project’s installed insulation is adequate from the start, future owners will not only enjoy a more comfortable working or living environment year-round, but it will also increase the structure’s energy efficiency and boost its overall value. Help future owners say goodbye to pesky drafts, high energy bills, and temperature fluctuations–and hello to a home or business that’s as cozy as it is cost-effective.

Why to Air Seal Your New Home Today

It’s the time of year when builders and homeowners are finalizing new home construction and remodeling plans.

It’s the time of year when many Maryland builders are finalizing new home construction projects. How much of a priority is air sealing and energy efficiency when planning your new home building project?

Investing in air sealing techniques during construction has a big payoff for both builders and ultimately homeowners. Air sealing improves comfort, lowers heating and cooling costs, boosts air quality, and increases the home’s value. Even better, it helps prevent future problems like moisture intrusion, mold growth, and comfort complaints. That means fewer callbacks for you and happier homeowners. Let’s dive deeper into the importance of air sealing your new home building project.

The Best Time to Seal is During Construction

It’s always best to do things the right way from the start. And this is very true when it comes to air sealing. Sealing your home building project while it’s under construction is far easier than doing it later. This is mainly because open framing provides clear access to open seams throughout your home project’s building envelope, including around plumbing and wiring. Plus, critical leakage points like top wall plates are only accessible before the walls are closed.

Insulation professionals agree that air sealing should be the first step in your home energy efforts before installing insulation. Air sealing and insulation are a small part of your construction budget that goes a long way in yielding outsized benefits while meeting Maryland’s energy building codes for an air-tight home.

Enhanced Comfort in Maryland’s Climate

Maryland weather swings between hot, humid summers and cold winters. Poorly sealed homes suffer from air leaks, uncomfortable drafts, hot or cold spots, and uneven temperatures. Help eliminate these problems and stop drafts and air leakage at their source by sealing around recessed lighting, windows and doors, sill plates, plumbing and electrical penetrations, attic access hatches, and more.

Air sealing helps keep indoor temperatures steady and reduces the strain on your HVAC system. This means fewer cycles, less noise, and lower heating and cooling costs. It all adds up to a more comfortable and energy-efficient home throughout every Maryland season.

Save Energy and Lower Utility Bills

In a typical home, air leaks can waste 25% to 40% of the energy used for heating and cooling. Sealing gaps and penetration points is one of the most cost-effective energy efficiency choices you can make. Many air sealing measures, like using spray foam and weather stripping, pay for themselves over time.

According to the U.S. Department of Energy, Maryland homes built to current 2021IECC energy codes will save homeowners about $264 annually on their utility bills. By taking the step to air seal during construction, you and your building team will be ahead of the curve as energy codes become stricter over time. The homes you build will be greener, more future-proof homes that use less energy, leave a smaller carbon footprint, and help Maryland meet its climate goals.

Healthier Indoor Air Quality for Families

When a home isn’t sealed properly, it lets in dust, pollen, mold spores, damp air, and even pests. Moist air can seep in and cause mold. This is especially concerning in our state where pollen levels are high during spring and summer.

The US Department of Energy says a tighter home envelope cuts down on these issues. By sealing up the cracks in your home building project you help control indoor moisture levels, prevent mold growth and wood rot, and keep out outdoor pollutants like car exhaust and smoke. This allows future residents or guests with asthma or allergies to breathe easier.

Pair your air sealing with proper ventilation, like bathroom fans, kitchen hoods, and Energy Recovery Ventilator (ERV) or Heat Recovery Ventilator (HRV) systems, and you’ll have a home that doesn’t randomly leak air but ventilates on your terms. In the end, you’ll have high customer satisfaction and a stronger reputation for building quality homes.

Boost Each Home’s Value and Durability

Great news! Energy-efficient homes are in high demand. Studies show that ENERGY STAR certified homes in Maryland sell for 2% to 5% more than less efficient homes.

A well-sealed home is also more durable. It’s less likely to suffer from moisture problems, hidden mold, or structural damage. It even extends the life of your HVAC equipment by reducing wear and tear. All these things add up to fewer homeowner callbacks and warranty claims, saving you and your building team valuable time and money.

Take Advantage of Incentives and Energy Programs

There are also financial incentives available for building energy-efficient homes. Through the Federal §45L Tax Credit builders can earn up to $5,000 in builder credit when their homes meet certain energy efficiency requirements.

Locally, Maryland’s EmPOWER program offers builder rebates for new home construction that qualify as ENERGY STAR certified (from $1,000-$3,000+ per home). There is also technical training and guidance available for builders to learn more about the best practices of insulation and air sealing. Creating homes that are ENERGY STAR certified provides third party validation for the energy efficiency of your new homes as well as marketing advantages for your business.

Build for the Future, Starting Today

Sealing your home building project during construction is one of the smartest choices you can make. It means a more comfortable and energy efficient home with better air, lower bills, and long-term value, as well as protection against moisture problems, and lower overall costs through incentives and reduced warranty issues.

How does air sealing work?

Sealing the “envelope” or “shell” of your home — its outer walls, ceiling, windows, doors, and floors — is often the most cost effective way to improve energy efficiency and comfort. ENERGY STAR estimates that a knowledgeable homeowner or skilled contractor can save up to 20% on heating and cooling costs (or up to 10% on their total annual energy bill) by sealing and insulating. To Seal and Insulate with ENERGY STAR:

  • Seal air leaks throughout the home to stop drafts,
  • Add insulation to block heat loss in winter and heat gain in summer.

Where are air leaks?

Many air leaks and drafts are easy to find because they are easy to feel — like those around windows and doors. But holes hidden in attics, basements, and crawlspaces are usually bigger problems. Sealing these leaks with caulk, spray foam, or weather stripping will have a great impact on improving your comfort and reducing utility bills.

Indoor Air Quality and Ventilation in New Construction in Maryland

Ventilation is becoming an important topic in the world of energy efficient homebuilding.

Older homes in Maryland weren’t built as tightly as today’s standards and were ventilated by natural air leakage rather than through controlled ventilation. Let’s not forget that some older homes had no insulation or insulation made of natural materials. These older products did not include volatile organic compounds (VOCs) or other additives commonly found in building products today, so ventilation wasn’t as much of an issue.

These days, modern energy-efficient homes are built with airtight seals to conserve energy, but this can lead to poor indoor air quality. Without proper air exchange, air pollution indoors can become a serious issue. In fact, the Environmental Protection Agency (EPA) reports that indoor air pollutants can be two to five times higher than outdoor levels. And since most of us, on average, spend nearly 90% of our time indoors, ensuring your building project is equipped with a proper mechanical ventilation system becomes essential for the health of future residents.

Key Indoor Air Pollutants

Exploring and understanding some of the most common contaminants can help you and fellow builders improve the indoor air quality of your future projects. Some of the most concerning indoor air contamination sources include:

  • Volatile organic compounds (VOCs): These chemical fumes are emitted from many building materials, VOC paints, furniture, and cleaning products and can cause health effects such as headaches, respiratory issues, and eye irritation.
  • Mold and Mildew: They thrive in high humidity levels and can trigger respiratory issues, especially for those with allergies and asthma.
  • Allergens: Dust mites, pet dander, and pollen can worsen allergies.
  • Excess Moisture: High humidity levels (above 50%) can lead to mold growth.
  • Other Contaminants: Carbon monoxide, radon, and particulate matter from cooking can all contribute to increased pollutant levels in indoor living spaces.

Ventilation System Types

To combat poor indoor air quality, builders of modern homes rely on mechanical ventilation systems to filter out the bad air and keep in the good air. There are several types of whole-house ventilation systems to consider for your new home building project:

Exhaust-Only Systems

These systems:

  • Use exhaust fans to remove stale air and create negative pressure.
  • Are simple and affordable but don’t filter incoming air.
  • Are best suited for colder climates.

Supply-Only Systems

These systems:

  • Push fresh outdoor air into a home, creating positive pressure.
  • Allow for filtration of incoming air.
  • Help prevent back drafting from combustion appliances.
  • Work best in warm or mixed climates.

Balanced Ventilation Systems

These systems:

  • Provide equal supply and exhaust airflow for consistent air exchange.
  • Deliver fresh outdoor air to specific areas.
  • Work well in all climates.
  • Cost more and may be more complex than other ventilation systems.

Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs)

These systems:

  • Transfer heat between incoming and outgoing air.
  • Maximize energy efficiency.
  • Manage humidity levels (ERVs only).
  • Have a higher upfront cost but perform better than some other ventilation systems.

Maryland-Specific Considerations

When it comes to Maryland and ventilation, here are a few considerations to make the case for quality ventilation in your building project.

  • Our state’s humid subtropical climate makes effective moisture management even more important.
  • Our high pollen levels greatly benefit from filtered ventilation.
  • Our state building codes require mechanical ventilation systems in new homes to reduce indoor air contamination.
  • ERVs are especially effective in our climate, balancing humidity levels while maintaining energy efficiency.

Best Practices for Builders

  • Plan for mechanical ventilation systems during your building’s design phase.
  • Install proper spot ventilation in kitchens and bathrooms.
  • Exceed code requirements for better performance.
  • Consider ERVs for optimal air exchange and comfort.
  • Conduct proper system testing and verification.

Best Practices for Future Homeowners

  • Maintain humidity levels between 30-50%.
  • Replace filters in HVAC systems regularly.
  • Use exhaust fans when cooking or showering.
  • Keep ventilation running continuously for optimal pollutant levels.
  • Monitor for unusual system noises or inefficiencies.

Benefits of Proper Ventilation

Investing in a good mechanical ventilation system offers several advantages that future homeowners and business owners will appreciate for many years to come:

  • Reduces indoor air pollutants and allergens.
  • Controls moisture to help prevent mold and mildew.
  • Enhances future residents’ comfort and overall well-being.
  • Protects home and building structure from moisture damage.
  • Ensures that Maryland building codes are met for modern construction.
