What Is A Building Envelope & Why Does It Matter?

by | Dec 12, 2018 | Uncategorized

Are you freezing in your office all winter long? Are you and your co-workers too hot in the summer? If your air conditioners and heating units are working and set appropriately, but you’re still experiencing these issues, the problem may be an improper building enclosure design.

What is a Building Envelope?

A building envelope (aka building enclosure) is the area of architecture, engineering, and design that determines a shelter’s ability to maintain proper climate control. This can include noise, water, heat, air, light, and more.

The Main Functions of Building Enclosure Designs

Proper building envelope design is essential to preventing leaks, high-energy bills due to heat and air escape, and more. However, the main functions of the building envelope are categorized as:

  • Support: Structural stability
  • Control: Climate control (water, heat, air, etc.)
  • Finishing: The way it is styled aesthetically

Proper building envelope design is essential to preventing leaks, high-energy bills due to heat and air escape, and more.

The Parts of a Building Envelope

Building envelope systems are made up of the following components and materials:

Windows

Window panels must be installed correctly and with care, to block any rain or harsh elements from entering a building. Properly sealed and tested, high-quality windows are important for allowing natural lighting into a building while also keeping it protected.

Doors

A well-sealed door can make a major difference in your energy bill and the temperature control in your home. In other words, the better the seal, the more money you’ll save.

Roof

A well-designed roof will keep bad weather out, blocking your property from rain damage and more. With vapour barriers, leak guards, and the right insulation and shingles, you’ll be well-equipped to handle the changing climate.

Walls

Your interior and exterior walls consist of a complex system of components that are necessary for structural support and functionality. These walls are also crucial in ensuring both heat and cool air do not escape your home or building.

Foundation

When it comes to the foundation of a building, proper drainage, waterproofing, and other efficiencies must be optimized for ultimate stability, safety, and compliance. Without these precautions, mould can form, walls can deteriorate, and other significant issues can arise.

The Impact of Water Penetration

At Keller Engineering Engineers, we perform a number of water penetration inspections on building envelopes, especially in condominium buildings. When water gets inside a unit, that’s a tell-tale sign that the Building Envelope has failed. If we suspect a building enclosure needs assessing, we perform a detailed inspection, recommend repairs, and often also supervise the repairs.

Without inspection, the following hazards can occur:

  • Evacuation of tenants
  • Mould development
  • Structural problems
  • Active leaks, etc.
