What today is considered to be "Sustainable Design" is what RDK has viewed as "responsible design" since our inception over 100 years ago. It's what we've believed in and what we've strived for as engineers throughout the century since, and it's evidenced in the projects we've completed. From our design and installation of the first underground steam distribution system in the U.S. in 1897, to our use of radiant heating in the 1940's, to our recent design of control systems for managing carbon dioxide levels to improve indoor air quality, we're proud of our achievements in advancing the state-of-the art in energy conservation, sustainable design, and good engineering practice.
Today, our continuing commitment to SustainableDesign is evidenced by the fact that nearly 20% of our staff are LEED

Accredited Professionals, knowledgeable in innovative, state-of-the-art Sustainable Design technologies. Our clients derive significant additional advantage, however, from the application of our "responsible design" philosophy to sustainable projects. We take a practical approach to the use of innovative technologies, employing those where our evaluation has demonstrated they will deliver real benefits.
As active members of the U.S. Green Building Council, we're involved in LEED

Silver, Gold, & Platinum certified projects, and upcoming LEED

Existing Building certification projects.
We are knowledgeable and experienced in evaluation, design, and/or commissioning and retro-commissioning of a wide variety of Sustainable Building Systems including:
- CO2 ventilation control systems
- Daylight & other specialty lighting control systems
- Photovoltaic Power & Solar Heating
- Wind Power
- Water conservation
- Grey water systems
- Rain water collection systems
- Fuel cell systems
- Micro-turbine systems
- Trending, benchmarking, and verification of utility meters
- Building & energy management software systems
- Energy recovery
- Occupancy ventilation control
Fuel cell technology, illustrated above was one of a number of sustainable power alternatives considered by RDK for use at Cape Cod Community College. Because fuel cells create electricity without combustion, they produce significantly fewer pollutants than conventional systems and are more efficient.
