Adaptive reuse is a method of construction that you may be familiar with, just by a different name, as it has been in use in the construction industry for decades.

Gut rehabs, renovations and retrofits; these are just a few ways that the methodology of adaptive reuse can be applied to construction projects. Adaptive reuse involves the conversion of office, industrial and other unoccupied buildings to meet the demand of housing, retail shopping and other reuse of existing assets.

As the world moves towards a more sustainable future, adaptive reuse can have the added benefit of reducing environmental impact through the generation of less waste and the use of less energy.

Benefits of Adaptive Reuse

The motivations for adaptive reuse and the reasons to convert and repurpose existing buildings and structures for modern purposes and sensibilities can be both aesthetic and practical.

Whether it be preserving the beauty of a vintage, artisan exterior/interior, converting a single-purpose building into a multipurpose one, or saving time and money by reducing the amount of construction/renovation phases, an adaptive reuse project is ultimately a conservation effort. One of the most meaningful aspects of an adaptive reuse project can be helping to lessen our impact on the environment.

When retrofitted during the adaptive reuse process, older buildings can achieve higher energy efficiency standards and reduce the amount of construction waste ending up in landfills. Repurposing existing buildings can be less resource-intensive than new building construction and, thus, more sustainable by minimizing the need for raw materials and their associated carbon emissions during production. In fact, research shows that adaptive reuse avoids 50 to 75 percent of the embodied carbon emissions that a new building would generate.

Challenges of Adaptive Reuse

Renovating an old building for a new purpose has many benefits, but there are some challenges that must be considered prior to beginning an adaptive reuse project.

The structural integrity of old buildings is first on the list of challenges. Buildings were made to last back in the day, but despite the artisanship and quality of materials used in the original construction of a building, the structure can be multiple decades or even hundreds of years old. This raises concerns about whether the building can still maintain active use with consistent occupancy.

Additionally, it is necessary to ensure that the building is code-compliant. Since safety standards are constantly being updated, there may be underlying issues that must be remediated prior to repurposing the building for modern use. These range from fire safety standards to weight restrictions and building materials that are up to code.

Combat the challenges of adaptive reuse with products designed to maximize performance and ease of installation. Achieve successful conversions of existing structures through a cross-portfolio solution from some manufacturers. 

Structural Panels

Structural Panels offer increased flexibility and ease of installation. The cementitious panels are factory-cured, noncombustible and can be installed with standard framing tools.

These panels handle like plywood and can be carried and delivered on pallets, even fitting on elevators for high-rise renovations. Their lightweight composition and versatility make them ideal for adaptive reuse projects with the ability to add floors, mezzanines and lofts in situations where weight restrictions would limit your options if you were to use a poured-concrete solution.

Glass-Mat Sheathing

Glass-Mat Sheathing can protect adaptive reuse projects with a noncombustible and moisture-resistant core, combined with a fiberglass face and back that provide exceptional moisture and mold resistance. Some panels are up to 15 percent lighter than other glass-mat gypsum sheathing panels, making handling and installation easier.

Self-Leveling Underlayments

If a building has a damaged, failing subfloor underlayment, a self-leveling underlayment solution can help repair and resurface to start fresh on an adaptive reuse project. This range of UL-classified and -specified products provide a smooth, strong surface that helps maintain the fire-resistance rating of the floor assembly while allowing for flooring installation to begin as quickly as the next day.

Floor Underlayments and Sound Mats

Many old buildings will have inadequate sound isolation that imposes quality of life concerns for tenants. Create sound-rated floor assemblies with a solution, utilizing sound mats and poured floor underlayment.

A sound-absorbing mat offers superior sound dampening and best-in-class STC and IIC ratings. Poured floor underlayments maximize sound isolation between floors with a smooth, quick-setting application and the highest compressive strengths in its class (2,000 to 3,200 pounds per square inch).

In Action

For a glimpse of a solution in action, look at this video of a recent adaptive reuse project at the Union League of Philadelphia.

This historic project utilized a combination of structural panels and glass-mat sheathing, adding an additional floor to the building’s over-100-year-old annex with a rooftop restaurant and offering strength and durability to ensure that the Union League continues to remain a fixture in the downtown area for years to come.
