Sustainable Interior Design
Design Haus · Walnut Creek & the East Bay
Thoughtful Materials.
Lasting Spaces.
Beautiful spaces begin with informed choices. We bring material transparency, life-cycle thinking and LEED-informed design together to help clients create interiors that reflect their vision and environmental priorities.

Our commitment
Sustainability shaped around your project
At Design Haus, sustainability is part of the conversation about how a space looks, functions and endures. From our Walnut Creek showroom, we help East Bay clients connect interior design, architectural planning and material selection with goals for indoor environmental quality, durability and responsible resource use.
For clients requesting a focused sustainability scope, we establish sourcing priorities early and review the product documentation available to support them. Our approach balances environmental objectives with aesthetics, performance, budget and availability, so decisions remain practical and personal.
Material transparency
Understanding the documentation behind a material
Different documents answer different questions. We use them together, where relevant to the agreed project scope, to understand environmental impacts, ingredient disclosure and product-specific performance.
Type III Environmental Product Declarations
An Environmental Product Declaration (EPD) reports life-cycle environmental data under ISO 14025 and applicable Product Category Rules. For material sourcing, we review the product covered, verification, validity and assessment boundary, including embodied-carbon information where reported.
An EPD provides transparency; it does not, by itself, certify that a product has a low environmental impact. Meaningful comparisons require compatible methods, units and life-cycle boundaries.
Health Product Declarations
A Health Product Declaration (HPD) presents product-content information and associated health-hazard screening. We review disclosure thresholds, identified ingredients, gaps in reporting and verification status when evaluating products against a client’s material priorities.
An HPD is a disclosure document, not a guarantee that a product is hazard-free. Ingredient reporting and indoor emissions testing provide different information.
Declare labels
Declare labels help communicate product ingredients and a product’s status against the Living Building Challenge Red List. We check the current label, exact product and declaration status: LBC Red List Free, LBC Red List Approved or Declared.
These statuses have different meanings. We review applicable exceptions and disclosure limits rather than treating every Declare label as equivalent.
Other relevant certifications
Depending on the material and project goals, we can review Cradle to Cradle Certified products, FSC-certified wood documentation and UL GREENGUARD Gold certification for low chemical emissions.
Each program addresses particular criteria. We check certification scope, validity and the specified product; no single label answers every sustainability question.
Life-cycle thinking
From cradle to grave—and toward circular use
Cradle-to-grave thinking considers a material from raw material extraction and manufacturing through transport, installation, use, maintenance and end of life. It is a life-cycle boundary, not an eco-label. An EPD may cover a narrower boundary, so we check which stages are actually included.
We consider opportunities to retain existing materials, select durable finishes, plan for repair and reduce unnecessary replacement. Where feasible, we explore reuse, manufacturer take-back and recycling options, checking local availability rather than assuming that every material can be recovered.
Cradle to Cradle Certified is a separate product certification program. It can inform circular material selection, but it is not interchangeable with a cradle-to-grave assessment.
Our sourcing approach
A clear process for sustainability-focused clients
Define priorities and scope
We begin with your goals: material transparency, lower embodied carbon, indoor air quality, responsible wood sourcing, longevity or a green building certification pathway. We agree on the level of research and documentation your project requires.
Request and review product evidence
For shortlisted materials, we request available EPDs, HPDs, Declare labels and relevant certificates from manufacturers or suppliers. We check that the documentation applies to the proposed product and identify missing or outdated information.
Compare options and explain trade-offs
We assess documented attributes alongside design intent, durability, maintenance, cost and lead time. Where evidence is incomplete or products are not directly comparable, we make those limits clear and discuss alternatives.
Coordinate selections and documentation
Within the agreed scope, we organize material records and coordinate with the project team on specifications and substitutions. If a product changes, we revisit the supporting information so the replacement can be evaluated against the same priorities.
LEED project support
Committed to projects pursuing LEED
Design Haus is committed to supporting clients who pursue LEED certification and those who want to apply LEED-informed strategies without seeking formal certification. We bring sustainable material selection and documentation into the design process early, coordinating with the project’s LEED lead and other consultants as needed.
Depending on the project, our agreed role can include organizing product disclosures, identifying low-emitting material options, reviewing responsible sourcing documentation and coordinating interior selections with the team’s energy, water, daylight and indoor environmental quality goals.
Documentation that fits the project’s requirements
LEED requirements depend on the applicable rating system, version and credit pathway. A product’s EPD, HPD or label may support a requirement, but does not automatically earn a credit. Certification applies to the project and is determined through the formal certification process.
Comfort, indoor air quality and enduring design
Material sourcing is one part of sustainable interior design. We also consider low-emitting product options, ventilation strategies, daylight, thermal comfort and finishes suited to everyday use. Together, these choices help connect environmental priorities with the way people live and work.
