REG specializes in innovative and alternative mechanical engineering. We start by working with the design team to minimize heating and cooling loads, which then allows us to use smaller systems or natural processes. We then design right-sized systems that can be effectively controlled and maintained. Our work is informed by extensive experience and collaboration with contractors. We also participate in projects as commissioning agents, owner’s representatives, or general consultants working with other engineers-of-record.



Our structural engineering practice is influenced by our construction experience and our philosophy of efficient building design. We offer “right-sized” design, clearly drafted plans and fast service at a competitive price. Our engineers have direct field experience as framers and general contractors, so we design for build-ability. We also can design and certify construction with alternative materials such as straw bales, clay-straw, Rastra-block/Perform-wall, ICF, and pumice-crete.



Electrical engineering is an important complement to our innovative mechanical engineering services. In addition to providing clear and concise electrical plans, we help the client consider major electrical system choices, such as single vs. polyphase service, primary vs. secondary delivery, and the extent of backup power systems. With our electric utility experience, we can effectively coordinate rate, delivery, and policy negotiations with the local electric company. We integrate on-site renewable generation to offset electrical consumption, whether grid-tied or off-the-grid. REG also keeps an eye on the future of electricity, including technology for distributed generation, dispatchable storage, metering and dashboard products, and smart grid integration.



Plumbing engineering completes the MEP puzzle. Although most plumbing designs are dictated strictly by code, it is still important to get the layout on paper for coordination with structure, HVAC, and even electrical equipment. A well-designed plumbing system minimizes conflicts, provides quick access to hot water without wasting water or energy, drains quietly, simplifies lifetime maintenance, and allows more accurate bidding when the project goes to construction. REG stays up-to-date on the latest code developments, some of which allow simplifications such as new venting technologies.


Commissioning + Existing Buildings

Commissioning is the process of making sure things work like they are supposed to. REG’s substantial commissioning experience has turned up just about every conceivable building operation issue, including backward-running fans, failed sensors, broken damper actuators, missing control wires, variable-speed pumps running continuously at full speed, and so on. Modern buildings are complicated beasts, and they need to be checked and rechecked to make sure they are operating properly.

REG’s commissioning work is informed by our focus on energy efficiency and our long history of designing systems with alternative approaches and advanced control strategies. We have strong relationships with HVAC and controls vendors and installers, and we’ve logged enough time in mechanical rooms and crawlspaces to have seen everything from old pneumatics to the latest GUI DDC interfaces. Our team can also help improve an existing building’s performance through the process known as retro-commissioning (for a building that hasn’t been touched in awhile) or re-commissioning (for a building that was recently constructed but still isn’t running right).
