Mechanical Engineering

Maximizing your energy savings

We help owners identify and design cost-effective, energy-saving building systems – with a constant focus on energy conservation. As new systems replace aging systems and as new buildings are designed, there is opportunity to adapt to contemporary standards, shifting to building systems that operate on electricity and away from fossil fuels. Greenbusch engineers evaluate options to drive down energy consumption by right-sizing systems to align immediate and long-term objectives, and opportunities to maximize budget through energy grants and rebates. We incorporate clients’ sustainable goals and work with owners and design team members to maximize energy savings, whether the project is new construction or renovation/adaptive re-use. We collaborate with clients to balance current needs with system performance and budget, and proactively evaluate where there are emerging needs to plan for future system upgrades.
