Sustainable Construction Practices
Sustainable construction is achieved through a series of deliberate, technically informed decisions that improve building performance, reduce operational demand, and enhance long-term durability. At Leedway Group, sustainability is integrated into the design and construction process through proven materials, high-efficiency systems, and building-science–driven execution.
Energy Efficiency & Building Performance
- Energy efficiency begins with a high-performance building envelope designed to minimize heat loss and air leakage. We utilize advanced insulation strategies such as dense-pack cellulose, mineral wool, and closed-cell spray foam to achieve continuous thermal barriers with high R-values. These assemblies are paired with airtight construction techniques, including fully sealed air barriers and blower-door–tested assemblies, to significantly reduce uncontrolled air infiltration.
- High-performance fenestration is specified using low-emissivity (Low-E) glazing, argon-filled units, and thermally broken frames to limit thermal bridging while maximizing natural light. Roof assemblies and wall systems are designed to reduce thermal bridging through exterior insulation where applicable.
- Mechanical systems are selected and sized based on detailed load calculations rather than rule-of-thumb assumptions. High-efficiency heat pumps, variable-speed HVAC systems, and zoned controls improve comfort while reducing energy consumption. Energy recovery ventilators (ERVs) are integrated to maintain fresh air exchange without compromising efficiency, particularly in airtight homes.
- Where appropriate, renewable energy strategies—such as solar-ready infrastructure or photovoltaic systems—are incorporated to further reduce grid reliance and support net-zero or near net-zero performance targets.
Indoor Air Quality & Healthy Living Environments
- Improving indoor air quality is a critical component of sustainable construction, especially in high-performance homes. Airtight construction is balanced with controlled mechanical ventilation to ensure consistent air exchange. ERV systems filter incoming air while maintaining humidity balance and energy efficiency.
- Material selection plays a significant role in air quality. We specify low-VOC and zero-VOC paints, sealants, adhesives, and finishes to reduce off-gassing and chemical exposure. Engineered wood products are carefully selected for compliance with formaldehyde emission standards, and natural materials such as solid wood, stone, and tile are used wherever possible.
- Moisture management is addressed through proper vapor control, drainage planes, and foundation waterproofing strategies to reduce the risk of mold growth and long-term material degradation.
Water Efficiency & Conservation
- Water conservation is addressed through both fixture selection and system design. High-efficiency plumbing fixtures, including low-flow faucets, showerheads, and dual-flush or low-consumption toilets, reduce water usage without sacrificing performance or comfort.
- Hot water systems are designed to minimize waste through optimized plumbing layouts, recirculation systems, and high-efficiency water heaters such as tankless or hybrid models. These strategies reduce both water and energy consumption associated with hot water delivery.
- Where applicable, we incorporate rainwater management solutions, permeable paving, and efficient drainage strategies to reduce runoff and support responsible site water management. Landscape designs may include drought-tolerant plant selections and efficient irrigation systems to further minimize outdoor water demand.
Material Selection, Durability & Waste Reduction
- Sustainable construction prioritizes materials that offer longevity, performance, and responsible sourcing. We favor engineered wood products for structural applications due to their efficient use of raw materials and dimensional stability. Exterior finishes such as fiber cement cladding, metal roofing, and masonry are selected for their durability, low maintenance requirements, and extended service life.
- Waste reduction strategies are implemented through accurate material take-offs, prefabrication where feasible, and on-site waste separation to divert recyclable materials from landfills. Durable design reduces the need for future replacements, contributing to lower lifecycle environmental impact.
- A Performance-Driven Approach to Sustainability. Rather than relying on labels alone, our approach to sustainable construction is grounded in measurable performance, proven systems, and long-term value. By integrating energy efficiency, indoor air quality, water conservation, and durable materials into every project, we create homes and spaces that are resilient, efficient, and designed to perform at a high level for decades to come.
