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

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.

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

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.

Building Envelope Design: Are You Doing It Backwards?

The status quo doesn’t make sense.

Think about it. A prudent architect wouldn’t design steel beam sizes and connections for the structural engineer to check later, nor design mechanical systems and then ask the MEP engineer to verify the sizing calculations. Yet somehow, we’ve normalized a process where architects draw building envelope details then ask building envelope experts to review and mark-up with corrections and recommendations.

50x ROI for Doing it Right

While kick-out flashing has been required by code for over a decade, CopelandBEC frequently sees instances of incorrect installation or, worse yet, omission altogether. We recently worked on a condominium community where the latter yielded costly consequences.
