What You Can Hire Us To Do:
Chances are good that you're looking for our Integrated Mechanical Design Service. That's where the magic happens. Baked into that service is not only the excellent engineering, but a deep expertise of building science from all perspectives - enclosure, thermal comfort, indoor air quality, etc.
To be clear, we design high performance HVAC systems. Just to be perfectly clear, we most often design systems that rely on Variable Capacity (VRF) HVAC equipment. If you don’t already, we recommend you get to know more about that by checking out our podcast episode on the subject!
Our Integrated Mechanical Design includes load calculations, equipment selection, full scaled duct design, humidity control, make up air, diffuser selection/coordination, and engineering drawings in Revit (or superimposed on DWG floor plans). Our service a level of design resolution that is not a part of mainstream architecture and engineering practice. If you're just looking for a Manual J or similar minimal service, we're not the right fit for your project.
Why Our Service Is Important & Valuable:
Simply put, HVAC installers and mainstream MEP engineers launch into designs thinking about air handlers, plenums and ducts, while we start by thinking about your enclosure, your pulmonary system and health, and how your body perceives comfort. Having a carefully designed, high performance HVAC system is the most sensible way to deliver health and comfort in your home or building. Positive Energy has a team of passionate, creative, and thoughtful engineers and we love what we do.
We are fortunate to be partnered with some of the best residential architecture firms in the world. In fact, here’s what a typical Positive Energy client looks like. Our very simple intent is to manage the complexity of delivering robust mechanical systems to deliver comfort and better air quality and help architects design around people. We’re proud of the hundreds of successful projects to which we’ve brought our expertise all over the world. The value of our designs is clear - you just have to decide if you’re ready to take the plunge into a different level of quality.
How Much It Costs:
Integrated Mechanical Design™ | Pricing ranges 0.5% - 1% of construction cost
Price accounts for footprint, square footage, and architectural complexity (i.e. are there mechanical closets, spatial allotments for ductwork, high window to wall ratio, etc.)
Our design fee is separate from the total cost of installed equipment (averaging 4% - 6% of construction cost, based on ~$300-$500/sf projects)
Design fee minimum is $5k
If you’re looking to get a hydronic (radiant) system design, expect a premium
Residential High Performance Hot Water Design | $.50 - .$75 per Square Foot
When To Bring Us Into The Project:
Just in case you didn’t know, the architectural design process is typically broken down into phases: Massing, Programming, Schematic Design, Design Development, and Construction Documents. The best way to get us involved is actually during the schematic design phase or earlier (check out the attachments to get a sense for how and when we intersect). If you’ve already got construction documents, it’s much more complex to design mechanical systems for a space where no negotiation is possible.
A few things to consider here:
Our project timeline is about 6 weeks out from the point of signed contract. Don't let us hold up your project - if you're already to CDs and plan on starting construction in the next couple of weeks, we're probably not the right fit.
Have you or your team ever worked with a mechanical engineer before in a residential context? If you don't know, ask.
What is the target construction timeline for the project?
Have any HVAC installers with knowledge of VRF systems been considered for the project?
What is your ideal budget for HVAC systems for the project?
