Net Zero and Passive homes are the ultimate in sustainable building and is the cutting-edge progression of where home building can go. In the 21st century, building science and technology have united and the old models of home building are quickly fading. We couldn’t be happier about that since The Green Cocoon is a green company that strives to make little to no negative impact on the environment.

What Is Net Zero?

Zero net energy (ZNE) building, also known as zero-energy building (ZE), and net-zero energy building (NZEB), is a building with zero net energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site, or in other definitions by renewable energy sources offsite. In some cases, these buildings consequently contribute less greenhouse gas overall to the atmosphere during operations than similar non-ZNE buildings.1One of the easiest ways to attain a net zero energy home is by following the design principles of the Passive House standard.2  Homes designed to this standard consume 90% less energy than a home built to code standards today!

What Is a Passive House?

“Passive building comprises a set of design principles used to attain a quantifiable and rigorous level of energy efficiency within a specific measurable comfort level.” A passive building is designed and built in accordance with these five building-science principles:

Employs continuous insulation throughout its entire envelope without any thermal bridging.

The building envelope is extremely airtight, preventing infiltration of outside air and loss of conditioned air.

Employs high-performance windows (double or triple-paned windows depending on climate and building type) and doors – solar gain is managed to exploit the sun’s energy for heating purposes in the heating season and to minimize overheating during the cooling season.

Uses some form of balanced heat- and moisture-recovery ventilation.

Uses a minimal space conditioning system.

As residents of New England, we may not face hurricanes as frequently as our counterparts in the southern U.S., but the impact of intense storms, floods, and coastal surges is not foreign to us. In light of the devastation caused by hurricanes like Harvey, Irma, and Maria, it's crucial for homeowners in our region to also consider the role of insulation in post-hurricane home repair.

Here we’d like to explore the challenges posed by flooding and storm surges, the shortcomings of traditional insulation, and why closed-cell spray foam insulation, a FEMA-recognized flood-resistant material, emerges as a resilient solution.

Understanding the Impact of Hurricanes in New England

While New England is not a hurricane hotspot, we've witnessed the aftermath of intense storms that bring heavy rain, flooding, and potential storm surges along the East Coast. Coastal flooding poses a significant threat to homes, leading to physical deterioration, mold growth, and a host of other issues. According to FEMA, flooding is a major contributor to over $3.5 billion in insurance claims annually, and the risks associated with storm surges and underperforming drainage systems are ever-present.

The Pitfalls of Traditional Insulation

Traditional insulation materials, such as fiberglass and cellulose, excel at insulating homes from seasonal temperature variations but offer little protection against flooding. When floodwaters infiltrate a home, these materials become laden with moisture, rendering them unable to dry out quickly enough to prevent damage. Mold growth becomes a significant concern, posing health risks and complicating the post-hurricane cleanup process. Recognizing these limitations, FEMA emphasizes the importance of flood-resistant building materials in the reconstruction or repair of hurricane-impacted structures.

Closed-Cell Spray Foam: A Flood-Resistant Solution

FEMA identifies closed-cell spray foam insulation as a flood-resistant material falling into Class 4 or Class 5 of its flood damage-resistance classification system. Unlike traditional insulation, closed-cell spray foam quickly becomes rigid, adding structural integrity to roofs and reducing the risk of blowoff during hurricanes. This resilience makes it a valuable asset for homes in areas prone to flooding, hurricanes and heavy storms (like any nor’easter for example) J

Key Features of Closed-Cell Spray Foam Insulation

1. Structural Integrity: Closed-cell spray foam insulation, like that available from Icynene, enhances a home's structural integrity. This feature becomes crucial during hurricanes, where the rigidity of the insulation helps fortify roofs against the forces of strong winds.
   
2. Bulk Water Ingress Resistance: Closed-cell spray foam's ability to reject bulk water ingress is a game-changer in flood-prone areas. Applied in spaces like basements or crawlspaces, it helps reduce the risk of significant damage caused by hurricanes, storms, and their associated floodwaters.
   
3. Air-Sealing Qualities: Beyond flood resistance, closed-cell spray foam insulation's air-sealing qualities contribute to long-term benefits. Homeowners can potentially reduce the size of their heating and cooling equipment, leading to energy savings and enhanced comfort throughout the year.
   

Preparing for the Future: A Resilient Home with Closed-Cell Spray Foam

As we've witnessed an increase in the intensity of hurricanes and heavy storms over the past 30 years, the importance of resilient home construction cannot be overstated. Having a home insulated with closed-cell spray foam insulation is an effective strategy to ensure preparedness for the next hurricane season. By leveraging its flood-resistant properties, structural benefits, and energy efficiency, homeowners can fortify their homes against the challenges posed by intense storms.

In the face of unpredictable weather patterns and the increasing intensity of hurricanes, New England homeowners must prioritize resilience in home construction and repair. Closed-cell spray foam insulation emerges as a FEMA-recognized flood-resistant solution, offering structural integrity, water ingress resistance, and long-term energy efficiency. As we navigate the complexities of our region's climate, investing in closed-cell spray foam insulation becomes a proactive step towards fortifying our homes and ensuring the well-being of our families in the aftermath of intense storms and flooding.

People often neglect their attics, leaving them unexplored for years. However, checking your attic during the winter is of paramount importance. This is the time when condensation becomes a significant concern. Attic moisture can lead to various problems, and it's crucial to understand the causes and consequences of this issue. In this blog, we will explore the reasons why it's important to inspect your attic for moisture in the winter, the potential causes of condensation, and why it's not always a roofing problem.

The Impact of Condensation

Condensation is a major adversary for your home, and it can cause a range of issues. It can occur when warm, moisture-laden air from the interior of your home rises into the attic and meets a cold surface, typically the roof deck. This clash of temperatures causes the moisture in the air to condense into water droplets. Over time, this can lead to various problems, including:

1. Mold and Mildew Growth: Excess moisture in the attic provides an ideal environment for mold and mildew to thrive. This can lead to health problems for your family and structural damage to your home.
2. Insulation Problems: Condensation can saturate insulation materials, reducing their effectiveness. Inadequate insulation can result in energy loss and higher utility bills.
3. Structural Damage: Prolonged exposure to moisture can compromise the integrity of your attic's structure, including wooden beams and rafters, potentially leading to expensive repairs.
4. Reduced Energy Efficiency: A damp attic can affect your home's energy efficiency. Your heating system will have to work harder to maintain a comfortable temperature, leading to higher energy bills.

Common Causes of Attic Moisture in Winter

Several factors contribute to attic moisture during the winter, making it essential to regularly check your attic for issues. Here are some common culprits:

1. Inadequate Air Barriers: Older homes often lack proper air barriers between the living space and the attic. This allows warm, moist air to infiltrate the attic, leading to condensation when it meets the cold roof deck.
2. Can Lights: Recessed can lights can create openings in the ceiling that allow warm air to escape into the attic. These fixtures are a common source of heat and moisture transfer.
3. Unsealed Attic Hatch: An unsealed attic hatch provides an easy path for warm indoor air to flow into the attic. When this air cools, it can lead to moisture problems.
4. Poor Ventilation: Proper attic ventilation is crucial for removing excess moisture before it can condense. Inadequate or blocked ventilation can exacerbate moisture issues.

Proper Attic Ventilation

Proper ventilation plays a vital role in maintaining a healthy attic environment. When designed correctly, it allows air to circulate, reducing humidity and preventing condensation. Here's why proper attic ventilation is essential:

1. Preventing Moisture Buildup: Adequate ventilation helps remove excess moisture from the attic, preventing condensation and related problems.
2. Extending Roof Lifespan: Well-ventilated attics can help extend the lifespan of your roofing materials by preventing moisture-related damage, such as rot and mold growth.
3. Improving Energy Efficiency: A properly ventilated attic can enhance your home's energy efficiency by reducing temperature extremes in the attic space, making it easier to maintain a comfortable indoor temperature.
4. Enhancing Indoor Air Quality: Good attic ventilation can prevent the infiltration of mold and mildew spores into your living space, which can improve indoor air quality and protect your family's health.

Misconceptions About Roof Leaks

Many homeowners who discover moisture in their attic automatically assume they need roof repairs. However, in most cases, it's not a roofing problem but rather an issue related to ventilation or moisture. Here are some misconceptions about roof leaks:

1. Visible Moisture Equals a Roof Leak: Seeing moisture in your attic doesn't necessarily mean there's a roof leak. In many cases, the moisture results from other factors, such as poor ventilation or excess indoor humidity.
2. Roof Damage Is the Culprit: Assuming that roof damage is the root cause can lead to unnecessary expenses. Before scheduling costly roof repairs, it's essential to investigate the underlying issue, which may be related to ventilation or insulation.
3. Year-Round Problem: Attic moisture is more common during the winter due to the temperature difference between the warm indoor air and the cold attic space. It may not be an issue during the summer months.
