The Pressure Is Rising—and It’s Not Just the Heating Bills
If you’re building multi-family housing in Massachusetts, New York, or Connecticut, chances are you’ve already felt the pressure: tighter energy codes, shorter build timelines, and zero tolerance for post-installation surprises. Windows—often an afterthought in early spec planning—are now one of the highest-risk line items in your development budget.
So why are more developers reconsidering their approach to window selection?
Because one missed spec or late shipment doesn’t just stall one subcontractor—it can halt your entire schedule, blow through your budget contingency, and risk code noncompliance that delays occupancy.
Let’s break down why spec decisions around windows are evolving fast—and how to stay ahead of the curve.
Energy Code Requirements Have Leveled Up
In 2023, Massachusetts adopted one of the strictest building energy codes in the country, pushing U-factor requirements for windows in new construction even lower. New York and Connecticut followed with similar updates. Projects that would have passed inspection just a year or two ago are now being flagged for insufficient thermal performance.
What this means for developers:
You can’t afford subpar product specs.
ENERGY STAR® certification is no longer a luxury—it’s the baseline.
Inspectors are scrutinizing window cut sheets more than ever.
And with the federal Energy Efficient Home Improvement Credit offering up to $600 per unit in tax credits for ENERGY STAR® Most Efficient windows, savvy developers are using window upgrades to improve ROI and boost tenant satisfaction.
ENERGY STAR® Certification and Local Code Compliance
ENERGY STAR-certified windows meet or exceed performance thresholds required by code in most Northeastern states. Many rebate programs and green certifications (e.g., LEED for Homes, Energy Efficient Home Improvement Credit) require these certifications as a baseline.
Rework Is Costing Developers Millions
We’ve spoken to developers across the region who’ve faced expensive lessons:
“We had to remove and replace an entire building’s worth of sliders because the specs didn’t meet updated MA code. Nobody caught it in time—and we lost three weeks.”

Whether it’s misaligned U-factors, incorrect sizing due to design miscommunication, or warranties that don’t extend to commercial-grade use, the cost of choosing the wrong supplier—or not reviewing specs early enough—adds up fast.
When windows become a liability, developers eat the cost—not the vendor.
Reliability Matters More Than Ever in Multi-Phase Builds
Multi-family projects don’t get built in a vacuum. Most developments are phased over time. You need a window supplier who can:
Deliver on time, every time
Guarantee consistency across phases and sites
Lock in pricing for long-term planning
Unfortunately, many vendors just aren’t built for that. They treat windows as a commodity and leave you holding the bag when delays or spec mismatches occur.
That’s where Kasson & Keller changes the game.
