Most homeowners focus on individual home repairs – fixing a leaky faucet, replacing insulation, or patching drywall. But few consider how all the components of their home work together to affect energy efficiency, air quality, moisture control, and long-term durability.
This is where building science comes in.
Building science is the study of how buildings perform as a system – how air, heat, moisture, and materials interact to create a safe, efficient, and comfortable home. When one part of a home isn’t functioning correctly, it can impact the entire house.
Understanding Building Science: The Key Factors
1. Moisture Management: The #1 Threat to Homes in the Pacific Northwest
The Puget Sound region is known for high humidity, frequent rain, and damp conditions – all of which can lead to mold growth, wood rot, and insulation damage.
- Building Science Principle: Moisture moves through homes in three ways – bulk water (leaks), vapor diffusion (humidity), and air transport (drafts). Managing drainage, ventilation, and insulation together is key to preventing moisture-related damage.
- Common Problems:
- Poor attic or crawl space ventilation leads to trapped moisture and mold.
- Inadequate drainage causes standing water in basements and crawl spaces.
- High indoor humidity leads to condensation on windows and walls.
- Building Science Solution: Proper air sealing, vapor barriers, and ventilation work together to control moisture and prevent damage.
2. Airflow & Ventilation: Keeping Your Home Healthy
Many homeowners think insulation alone keeps their home comfortable, but airflow is just as important. Poor ventilation leads to stale air, excess humidity, and increased allergens.
- Building Science Principle: Homes need controlled air exchanges, by controlling the amount and source of the fresh air entering and exiting the building. The home is separated into conditioned and unconditioned portions of the house. Each section has their own requirements based on a variety of factors. All factors need to be considered to create a functioning healthy home.
- Common Problems:
- Poor attic ventilation causes heat buildup in summer and moisture problems in winter.
- Crawl spaces with inadequate airflow trap humidity, leading to mold and pest issues.
- Sealed-tight homes without proper ventilation can have poor indoor air quality.
- Building Science Solution:
- Balanced ventilation (exhaust fans, air exchangers) improves indoor air quality.
- Air sealing and insulation work together to eliminate drafts and control heat gain/loss.
- Crawl space encapsulation prevents humidity-related damage.
3. Energy Efficiency: How Your Home Uses & Wastes Energy
If your home feels drafty in winter or overheats in summer, it likely has thermal inefficiencies. Building science helps homeowners reduce energy waste and improve comfort.
- Building Science Principle: Heat moves in three ways – conduction (through materials), convection (air movement), and radiation (solar heat gain). A well-designed home minimizes heat loss in winter and keeps heat out in summer.
- Common Problems:
- Leaky windows and doors let conditioned air escape.
- Poorly installed insulation creates temperature inconsistencies.
- Inefficient HVAC systems work harder to compensate for heat loss/gain.
- Building Science Solution:
- Proper insulation placement reduces heat transfer.
- Air sealing and weatherproofing reduce energy waste via air leakage.
- Efficient HVAC systems and humidity control improve comfort year-round.
4. Home Durability: Preventing Long-Term Damage
Your home’s roof, walls, foundation, and insulation all work together to maintain its structural integrity. Poor moisture management, ventilation, or insulation can cause early deterioration and expensive repairs.
- Building Science Principle: A well-maintained home envelope (roof, siding, insulation, foundation) protects against moisture, temperature fluctuations, and structural decay.
- Common Problems:
- Efficient HVAC systems and humidity control improve comfort year-round.
- Condensation buildup leads to mold and rot inside walls.
- Unsealed crawl spaces allow moisture, pests, and foundation damage.
- Poorly installed materials shorten a home’s lifespan.
- Building Science Solution:
- Proactive maintenance prevents minor issues from becoming major repairs.
- Sealing and reinforcing weak points extends a home’s lifespan.
- Comprehensive moisture control keeps structures dry and strong.
