Better insulation, upgraded heating and cooling equipment, and modernized management systems for existing residential and commercial space — retrofits scoped to the building you have, not the one a catalog assumes you have.
Most buildings weren’t built with today’s energy costs in mind. Building Retrofitting closes that gap — improving insulation, replacing aging heating and cooling equipment, and adding smarter management systems so an existing structure performs like a new one, without the cost or disruption of new construction.
Every retrofit starts from the findings of an Energy Audit, so the work is prioritized around the measures with the fastest payback, not just the most visible ones.

Better comfort, year-round
Tighter envelopes and modern HVAC even out temperature swings room to room.

Lower operating costs
Upgraded equipment and controls reduce the energy needed to run the building day to day.

Higher asset value
A retrofitted building is more efficient, more comfortable, and more attractive to buyers or tenants.
A retrofit plan can include one category or all three, depending on what your Energy Audit turns up.
Insulation & Building Envelope
Sealing and insulating the shell of the building so conditioned air stays where it belongs.
Heating & Cooling Equipment
Replacing aging systems with right-sized, high-efficiency equipment.
Smart Management Systems
Modernizing how the building is scheduled, monitored, and adjusted.
Single-Family Homes
Multi-Family Buildings
Office & Commercial Space
Industrial Facilities
Community & Institutional Buildings
Rank the opportunities
Start from your Energy Audit findings, ranked by cost, savings, and payback.
Scope the work
Choose envelope, mechanical, or controls upgrades — or all three — to fit your budget.
Execute the retrofit
Work is scheduled to minimize disruption to residents, tenants, or operations.
Confirm the savings
Post-retrofit data analysis confirms the upgrade is performing as projected.
It’s strongly recommended. An audit identifies which upgrades will pay off fastest for your specific building, so the retrofit budget goes toward the measures with the biggest impact rather than guesswork.
In most cases, no. Retrofit work is scheduled around occupancy and operating hours, and phased so residents, tenants, or staff can stay in place throughout the project.
A single-category retrofit — insulation alone, for example — can often be completed in days. A full envelope, mechanical, and controls retrofit on a larger commercial building may take several weeks, scoped during planning.
Yes. Retrofits can be paired with our Energy Finance Solutions, including performance contracting and energy service agreements, so upgrades don’t require full upfront capital.
