Five Material Decisions to Discuss for a More Efficient Home

Compare complete assemblies

A material’s marketing label does not tell you how the finished home will perform. Ask how the product works with the rest of the design, what evidence supports its claims and what installation or maintenance it requires. The following five decisions are useful starting points for a discussion with your design and construction team.

1. Windows suited to the design

Compare rated performance rather than frame appearance alone. The US Department of Energy explains that window performance depends on factors including frame, glazing and climate. Use product labels and the home’s orientation to discuss the appropriate choices with the designer; do not assume one glazing option is best for every room.

2. Insulation and air-sealing details

Ask how the proposed insulation fits the wall or roof assembly and how gaps and penetrations will be addressed. Discuss moisture considerations and installation quality with the responsible specialist. Product specifications should match the design rather than being selected from a generic list of green materials.

3. Framing with documented sourcing

If certified or recycled-content materials are a priority, ask suppliers for product-specific documentation and availability. Confirm structural suitability with the designer. Avoid assuming that a recycled-content claim alone proves lower environmental impact across the product’s full life cycle.

4. Interior finishes with clear product information

Request the relevant emissions, composition and care information for paints, flooring and adhesives. Consider how finishes will be used and maintained in your home. Evaluate the exact products together with installation requirements instead of treating an entire material category as automatically healthier.

5. Exterior materials selected for service life

Discuss exposure, drainage, repairability and maintenance when comparing siding, roofing and other exterior finishes. A choice should fit the local conditions and the home’s detailing. Ask what routine care is required and whether replacement components will be available.

Turn preferences into specifications

Prioritize the goals that matter most to you, then ask the team to document the product, evidence, cost and alternatives for each decision. Environmental or energy savings should be supported by project-specific analysis; this checklist does not promise a particular reduction.
