Energy Efficiency upgrade for South Shore Apartment Complex
At Able Home Performance, we pride ourselves on delivering high-quality energy-efficiency solutions for both residential and commercial clients. Recently, we had the privilege of completing a large-scale project for a 23-building apartment complex, spanning over 83,000 square feet, where we significantly improved the energy performance of the properties. We’re excited to share the results and the estimated energy savings for the residents now that the buildings are fully air sealed and insulated.

The Project Overview
This commercial project involved air sealing and insulating the attics of 23 buildings in an apartment complex. Our team focused on several key energy-efficiency improvements, which included:
- Air Sealing Attic Penetrations: We ensured that all penetrations in the attics, such as plumbing stacks, wiring, and ductwork, were properly air sealed. These penetrations, if left untreated, allow conditioned air to escape, increasing energy costs. Over 65 Cases of Air Sealing foam were used.

- Attic Stair Covers: To further reduce air leakage, we installed insulated attic stair covers on all attic accesses. Attic stairs can be a major source of heat loss if not properly insulated, so this step ensures a more energy-efficient seal between the living space and the attic.

- Blown-in Cellulose Insulation: We added blown-in cellulose insulation to the attics to achieve an impressive R-value of 49. This level of insulation is crucial in keeping heat inside during the colder months, reducing the need for excessive heating. This project took a whopping 4,393, 40 pound bags of cellulose to achieve the desired R-Value.

Timeline and Execution
The scope of the project was vast, and our team worked diligently to ensure it was completed efficiently and to the highest standards. In total, the project took two and a half weeks from start to finish. This rapid timeline was achieved thanks to our skilled team of energy professionals and well-coordinated project management. We ensured that the disruption to residents was minimal while delivering superior insulation results.
Estimated Savings for Residents
Now that the buildings have been fully air sealed and insulated, the benefits for the residents will be noticeable almost immediately. Attic air sealing and insulation are some of the most effective methods to reduce energy costs. By preventing heat from escaping through the attic, the residents can expect to save significantly on their heating bills during the winter months.
Based on industry standards and similar projects we’ve completed, the residents of this apartment complex can expect to see a reduction in heating costs by up to 20-30%. For a typical apartment, this could translate to hundreds of dollars in savings over the course of the year. Not only will the energy savings be a relief for the residents’ wallets, but they will also experience increased comfort with fewer drafts and more stable indoor temperatures.
Why Air Sealing and Insulation Matter
Air sealing and insulation are critical components of any energy-efficient building, whether it’s a single-family home or a large apartment complex like this one. Without proper insulation, heat escapes through the attic, walls, and windows, forcing heating systems to work harder to maintain a comfortable temperature. The result is not only higher energy bills but also unnecessary wear and tear on heating equipment, leading to more frequent repairs and replacements.

By adding insulation to an R-value of 49, we’ve ensured that the apartment complex is well-equipped to retain heat during the winter and stay cooler during the summer. This not only leads to lower energy costs but also reduces the environmental impact of the complex, as less energy consumption translates to lower greenhouse gas emissions.
A Bright Future for Energy Efficiency
At Able Home Performance, we are proud of the work we’ve done for this 23-building apartment complex, and we’re excited to see the positive impact it will have on both the residents and the environment. Projects like this one highlight the importance of energy-efficiency upgrades, not just for the immediate cost savings but also for long-term sustainability.
As energy costs continue to rise, investing in air sealing and insulation will become an increasingly valuable solution for property owners and managers looking to improve the comfort and efficiency of their buildings.
