The Roanoke Valley is home to a rich architectural tapestry, from the classic Victorians of Old Southwest to the Craftsman bungalows of Grandin Village. These historic homes are a vital part of the community’s character, but bringing them into the 21st century can seem daunting. As The Gaines Group Architects establishes our new Roanoke office, led by local architect and history enthusiast Claude Breithaupt, we bring decades of experience in historic renovations and a pioneering commitment to sustainable design in Virginia.

We believe that preserving a home’s legacy and maximizing its performance can, and should, go hand-in-hand.

Here are our expert strategies for designing an economically sustainable historic home renovation right here in the Roanoke Valley:

1. Lead with Building Science: Prioritize the Envelope
The most “sustainable” feature of a historic home is often its existence—the embodied energy already spent. Our first step is always to ensure the building will last for generations to come.

• • Focus on Air Sealing First: Historic homes are notoriously leaky. Before spending money on new HVAC systems, we focus on air sealing the home’s “envelope” (roof, walls, and foundation). Air sealing is one of the most cost-effective upgrades, immediately reducing energy loss and utility bills.
    
    • • • Economic Insight: Simple steps like adding weatherstripping, caulking gaps, and insulating the attic or crawlspace yield a massive return on investment (ROI) by minimizing the size and cost of new mechanical systems needed later.

• Strategic Insulation: Instead of wholesale gut renovations, we look for targeted insulation solutions. Modern spray foam in attics or insulated concrete walls in basements can dramatically boost performance without disturbing historically significant interior finishes.
• Consult for Longevity: Old buildings are complex systems. Our approach—rooted in building science—helps clients avoid common pitfalls, like installing modern vapor barriers that can trap moisture and cause rot in historic wood framing. We design for durability, which is the ultimate form of sustainability.

2. Maximize Value Through Programmatic Planning
A successful historic renovation is about understanding the opportunities and the limitations of the existing structure before a single wall is opened.

3. Embrace Low-Impact, High-Performance Systems Sustainability in historic renovations means integrating the best of modern technology in a way that is sensitive to the original design.

• Mechanical Efficiency: We often specify high-efficiency heating and cooling, such as mini-split ductless HVAC systems. These systems are relatively non-invasive, requiring minimal ductwork and allowing for targeted climate control in different zones of the historic home.
• Healthy Materials: Aligned with our mission to design healthy environments, we select materials that improve indoor air quality. This includes choosing low- or no-VOC (Volatile Organic Compound) paints and stains and utilizing durable products that last, avoiding the need for frequent replacement.
• The Existing Framework as a Resource: The solid wood framing and durable exterior materials of many Roanoke historic homes are inherently sustainable. We prioritize repairing and reusing these elements rather than replacing them, reducing landfill waste and honoring the original craftsmanship.

Renovating a historic home in the Roanoke Valley is an act of civic stewardship. When approached with an expert understanding of design, building science, and economic strategy, you can create a beautiful, healthy, and high-performing home that continues to serve the community for another century.
