Enclosures, Risk, and the Power of Early Strategy
The building industry has gotten remarkably good at understanding enclosure failures. We know the failure points, the root causes, the cascade effects. Research from NIBS and building enclosure councils has documented patterns with precision. What's less developed is our ability to act on that knowledge early enough to matter. Despite decades of field experience showing that most enclosure problems originate in design decisions, façade strategy still tends to get serious attention after the major moves are locked in.
The Compounding Problem in New York City
New York's regulatory environment has created something interesting: overlapping compliance cycles that force building owners to think about enclosures strategically, not reactively.
LL11 inspections happen every five years. LL87 energy audits every ten. LL97 carbon caps tighten progressively through 2050. The owners who treat these as isolated compliance exercises (patch the façade, check the box, move on) end up in a cycle of expensive interventions that never address root causes.
The smarter play is recognizing these aren't separate problems.
A façade restoration project isn't just about LL11 compliance; it's an opportunity to improve thermal performance for LL97, address air leakage driving up HVAC loads for LL87, and get the building envelope working with (rather than against) mechanical systems. But that only happens when someone at the table understands how these systems interact, not just what the regulations require.
Why Early Decisions Matter More Than We Act Like They Do
Here's the uncomfortable truth: research shows that schematic design decisions determine 70–80% of a building's lifecycle performance. Yet façade strategy typically gets serious attention sometime around design development … after the major moves are locked in.
By the time enclosure consultants are reviewing shop drawings, the game is largely over. HVAC has been sized. Structural coordination points are set. The building's thermal and moisture management strategy is embedded in decisions made months earlier, often by people focused on other priorities.
The gap isn't knowledge; it's timing and integration. High-performance buildings happen when enclosure and MEP strategies develop together, when someone who understands both is in the room during schematic design, when performance targets drive decisions rather than validate them after the fact.
The Shift from Static to Responsive
The more interesting development in façade technology isn't any single product—it's the fundamental shift from building skins as passive barriers to active performance systems.
Vacuum insulated glass and electrochromic glazing that adjusts to conditions. Prefabricated assemblies that move quality control from the job site to controlled factory environments. AI-driven diagnostics that predict failures before they become crises. These aren't novelties. They're responses to the reality that our performance expectations have outpaced what static systems can deliver.
The challenge isn't adopting new technology. It's recognizing when traditional approaches are actively working against your building performance goals, and having someone who can articulate why a different strategy makes sense for your specific project.
The Value of Actually Verifying What You Designed
Building Enclosure Commissioning exists because "designed to perform" and "performs as designed" are often two different things.
The value isn't in checking boxes for LEED credits. It's in catching the gap between what's on paper and what's being built before it becomes a performance failure or warranty claim. OPR development, design review, installation verification, performance testing: these aren't bureaucratic exercises. They're the difference between a building that meets its performance targets and one that generates expensive surprises two years after occupancy.
The question is whether verification happens systematically through commissioning, or reactively through remediation.
Where G&T Sits in This
Our role as project and cost managers puts us in an unusual position: we're invested in building performance but independent from design. We're not the façade consultant proposing systems, not the architect managing aesthetics, not the engineer sizing mechanical loads. We're the ones making sure all of that actually works together in practice.
That independence matters. When enclosure decisions affect MEP efficiency or construction sequencing or long-term operational costs, we can raise the question without a vested interest in the answer. When there's a gap between what's designed and what's buildable, we're positioned to identify it early – when solving it is a design conversation, not a change order.
We don't replace technical consultants. We make sure their work integrates, that performance goals drive decisions across disciplines, that risks get identified when they're cheapest to address. It's less about expertise in any single system and more about understanding how they all need to work together and recognizing when they won't.
For owners, that translates to fewer surprises, better alignment between capital investment and performance outcomes, and someone at the table who's thinking about the building as a system rather than a collection of independent scopes.
