Integrated Mechanical Design™


Integrated Mechanical Design Logo

Our signature Integrated Mechanical Design™ is a service that adds value to your project by using excellent engineering principles to design high performance HVAC systems for custom residential projects.

We fully integrate with the architect's design processes and support the project team with deep building science and construction expertise. Our designs support healthy homes and resilient, iconic architecture.

The above images are samples of mechanical pages done for a number of homes, designed by Positive Energy. Note that there are pages with design features for air based VRF systems, subterranean distribution systems, indoor air quality systems, hydronic heating/cooling systems, and performance based plumbing systems.


Heating/Cooling Load Calculations & VRF Equipment Selection

We use ASHRAE, ANSI and ACCA procedures to calculate your heating/cooling loads and we use manufacturers' expanded performance data to select the right equipment for your project. But we don't stop there.  An overall system concept and configuration includes thoughtfully defining indoor zones according to occupancy, exposure and orientation.

Full Distribution Drawings

Our designs clearly communicate the full distribution system of your HVAC, down to the diffusers. We distinguish between thermal comfort systems and indoor air quality systems so nothing gets missed. With a deep knowledge of how these systems work, we make sure enough clean fresh air gets to each space in your house with precision. Your installer will greatly benefit from having the guess-work removed from the equation. And you'll know what the equipment costs will be so you can make better installer decisions.
