Building Envelope Condition Assessments


THE BUILDING ENVELOPE IS EVERYTHING THAT SEPARATES THE INDOOR ENVIRONMENT FROM THE OUTDOOR ENVIRONMENT. THE SYSTEM YOU USE IS VITAL TO THE BUILDING’S PERFORMANCE.

In northern climates, temperature ranges as great as +30° C in the summer and -30° C in the winter offer the climate differential of the arctic to that of the tropics. We rely on the building envelope to keep us both warm and dry through those massive temperature fluctuations

Further complicating matters is the fact that the building envelope is not one thing or another. It is an assembly of many different parts, all of which must work together to stand against all weather eventualities.

From gleaming high-rise glass towers to low-rise brick and stucco buildings to single family residences with siding, the building envelope must:

  • Shed water from rain or snow
  • Drain water from rain, snow or condensation
  • Prevent air-leakage
  • Prevent vapour leakage
  • Insulate
  • Look aesthetically pleasing on both the interior and exterior sides

All too often, even though buildings may have been designed correctly, their as-built conditions do not reflect the intricate dance that the envelope must accomplish. Typically, failures in the construction include:

  • Leakage of walls, windows, doors or roofing
  • Damage to the concealed parts of the walls resulting in organic growth or structural failure
  • High levels of condensation on windows and walls

These failures typically present with some of the following symptoms:

  • Staining on interior finishes and exterior cladding
  • Damages to flooring or ceilings
  • Wet areas on windows or glazing
  • Dampness and musty smells
  • Visible decay or corrosion

Whether a single building or an entire community of condominium homes, building envelope condition assessments involve a holistic approach to understanding not the symptom, but the underlying cause of the symptom.

We employ teams of experienced building science practitioners who combine years of experience with the latest technological tools to assess conditions through both invasive and non-invasive techniques. Some of these techniques include:

  • Infrared scanning
  • Air leakage testing
  • Water testing
  • Blower-door depressurization
  • Moisture meters
  • Temperature and humidity readings
  • Evaluation of mechanical systems
  • Exploratory dismantlement

Upon the completion of our work in the field, we will prepare detailed and easy to read reports that detail the cause of the issues and the options for correcting them. It is often at this time that significant failures may lead to litigation; we can help with expert opinions and litigation support if required.

Achieving Optimal Solutions

Once we have determined the cause of the failure, Entuitive can serve as the Prime Consultant to design the repairs/restoration strategy, put the project out to bid and perform contract administration or project management services to ensure that it is built correctly the second time around.
