As design professionals, it is our social responsibility to advance and preserve our communities through innovative, sustainable design. We view sustainability as a design imperative that benefits our world holistically, protecting our natural resources, improving the human experience, and supporting our clients’ business objectives.

Integrated Design

Integrated Design defines our approach to continuously elevating the performance and sustainability of our projects. By leveraging our transdisciplinary practice to capitalize on the intersections between internal disciplines, we share expertise, gain new insights, and uncover innovative solutions to meet the challenges of sustainability and resilience. Our Integrated Design process achieves measurable sustainable outcomes by:

Fundamentally, we strive to holistically design systems and select materials that maximize energy conservation and human health. With both ethics and practicality driving us, it is our conviction to partner with our clients on rational, cost-effective solutions that reflect best practice sustainability.

2030 Commitment

By signing on to the AIA 2030 Commitment, Clark Nexsen has joined the select list of firms that are measuring the energy performance of their buildings and working to design all new buildings and major renovations to be carbon neutral by the year 2030. Our progress is significant; while we still have work to do, our average reduction of predicted Energy Use Intensity (pEUI) slightly exceeds the national average. With the implementation of our Building Science Group, project roadmap, and process software infrastructure for integrated design, our goal is to build on this momentum and continue to significantly improve project performance.

Building Science Group

Making the gathering and analysis of data intuitive to the design process is critical for our industry to achieve goals for high performance buildings and infrastructure. To advance this initiative within Clark Nexsen, our Building Science Group serves as a companywide resource for energy modeling and analysis with core goals to improve project performance and generate long-term operating cost savings for our clients.

The Building Science Group is integral to informing design decisions and improving Energy Usage Intensity (EUI) outcomes, providing dedicated, full-time access to energy modeling from concept design to construction documents.

Energy Modeling

Complex design solutions require robust analysis. Our energy modelers provide high level early analysis, deep dive analysis, and compliance modeling to complement and inform the design process from kick off to completion. High level analysis supports early concept design and may include massing/orientation studies, daylighting optimization, and energy analysis. Deep dive analysis assesses and answers more challenging questions that require thorough investigation – envelope constructions, building systems, moisture transmittance, and computational fluid dynamics, among others. Compliance modeling creates full scale energy models for code compliance or certifications such as LEED or Green Globes.
