It’s Wet. Is It a Leak, or Is It Condensation?

April 3, 2026April 14, 2026Carmen Prantil

There is water somewhere it is not supposed to be. It is not raining. There is no burst pipe nearby. And yet, wet. The heck?

First: Is It Actually a Leak?

This is the right question to start with, because condensation and water intrusion get confused often. The key difference is timing.

Water intrusion through the building envelope is driven by precipitation events. The water shows up during or after it rains or during a time of snow melt. It may not appear immediately, but there is a causal relationship with precipitation or melting.

Condensation is driven by temperature and humidity. It tends to appear in the morning, when surfaces are at their coldest after overnight temperature drop. It’s often worse in shoulder seasons — late fall and early spring — when outdoor temperatures have larger swings. It can appear on a completely clear, dry day. It correlates with weather, but the relevant weather variable is temperature, not rain.

The Thermal Envelope Certificate Is Not a Substitute for Stretch Code–Compliant Design

January 8, 2026January 8, 2026Matt

Under the Massachusetts Stretch Energy Code, the thermal envelope certificate is often misunderstood. It’s often treated as an administrative requirement to be addressed at the end of a project—something to be obtained after design and construction decisions have already been made. In reality, the certificate is intended to document compliance with the Stretch Code’s envelope performance requirements, not to create that compliance.

Importantly, the thermal envelope certificate cannot make a non-compliant wall assembly compliant. If the building envelope does not meet the required performance thresholds, no amount of documentation at the end of the project will resolve that gap.

Hands On: Exploratory Openings, Mock-ups, and Training

Building envelope systems work, or don’t, because of physical real-world details. Air and water don’t care how it’s drawn—the only thing that matters is how it actually is.

Exploratory Openings

When it comes to diagnosing what’s wrong with a building that’s not working right (if it’s leaking, for example) one of the best tools we have are exploratory openings. Sometimes called “probes”, this is essentially disassembling some parts of the building so we can see what’s under the surface.

Seeing the Forest: Getting the Big Picture on the 10th Edition MA Commercial Stretch Code

October 10, 2025April 8, 2026Carmen Prantil

Anyone manage to get the 10th Ed. Massachusetts Energy Code on their reading list this summer? It’s a real page-turner. (So we made you the SparkNotes).

Which Code Do I Follow?

In Massachusetts, the energy code isn’t one-size-fits-all; it’s a tiered system with 3 different levels, each having increasingly aggressive requirements.

The cost of deferred maintenance

September 29, 2025September 29, 2025Matt

In a reality where funding is scarce and resources are limited, how can you best allocate those dollars to care for your most valuable assets?

Status quo: deferred maintenance

Much of the time, proactive maintenance is viewed as a cost. Those inspections and routine repairs are perceived as money out the door. This widely-held perception has led to deferred maintenance becoming the norm for many facilities.

Deferred maintenance is the practice of postponing maintenance activities such as repairs… in order to save costs, meet budget funding levels, or realign available budget monies. The failure to perform needed repairs could lead to asset deterioration and ultimately asset impairment. Generally, a policy of continued deferred maintenance may result in higher costs, asset failure, and in some cases, health and safety implications. (Wikipedia, emphasis added)

What if, instead, we could better tell the story of how investments in proactive maintenance are not costs but actually grow the bottom line?
