Energy & Climate

We use energy modeling and simulation to inform high-performance design, compare design options, and support code and certification compliance. Our work spans national and regional energy standards; sustainability programs and certifications; and incentive, tax, and financing programs that require whole building energy modeling.

We support Passive House projects from early design through certification using both PHI and Phius pathways. Our services include design consulting, modeling, detailing, verification, and coordination to meet rigorous energy and comfort standards.

We help clients understand current performance and plan for future energy reductions. Our services support compliance with programs across North America in addition to organizational energy efficiency goals. We provide ASHRAE energy audits, decarbonization roadmaps, and retrofit planning aligned with both technical and financial goals.

We guide teams through certification programs with tailored modeling, credit documentation, and strategy support. We provide services for standards that include LEED, WELL, Zero Carbon Building (CAGBC), municipal sustainability requirements, and other certification programs.

We help design teams and building owners future-proof their buildings against climate risks. Our services are designed to ensure long-term performance, safety, and comfort in the face of extreme weather events, rising temperatures, and evolving environmental conditions. Whether it’s reducing overheating, improving indoor air quality, or enhancing durability, RDH delivers scalable, technically grounded solutions that support asset longevity and community resilience.

Buildings should perform as designed—delivering real, measurable energy savings and carbon reductions. Whether verifying whole-building performance, system-level efficiency, or post-retrofit outcomes, our team applies rigorous protocols and calibrated modeling to validate results. We support utility programs, pilot technologies, and high-performance projects with tailored M&V plans, sensor deployment, and data analysis.

As buildings become more energy-efficient, embodied carbon—the emissions associated with building materials and construction—has emerged as a critical climate concern, often becoming the largest source of emissions once operational carbon is addressed. Our team brings deep technical expertise in enclosure design, enabling us to guide clients toward low-carbon solutions that do not compromise durability. Using standardized LCA methodologies and detailed knowledge of materials and assemblies, we quantify emissions across all life cycle stages and provide actionable insights for design decisions Whether supporting policy compliance, certification targets, or internal sustainability goals, RDH empowers clients to make informed choices that drive real change.

We help shape the future of building performance by working with governments, agencies, and industry groups to develop building codes, industry guidelines, and incentive programs that drive market transformation. Our team brings deep technical expertise and real-world experience to support policy design, program evaluation, and stakeholder engagement. From national energy code task groups to municipal decarbonization studies, RDH is at the table—helping define the metrics, pathways, and tools that accelerate climate action and improve building outcomes.
