Performance Consulting—Guided by Building Science
Positive Energy is a unique firm. We actually might be crazy for doing the kind of work we do in the face of relatively low historical demand for it, but hey, that’s show business baby! Over the last 15 years, we’ve built our reputation and business on offering high-performance mechanical, electrical, and plumbing (MEP) engineering services to the residential architecture market with a focus on health, comfort, and decarbonizing. Given how rare it is to see MEP expertise brought into residential projects, we naturally drifted toward the high end of the market. And, as fun as it is to work on homes with endless budgets, our passion to make a broad societal impact left us wanting to find more ways to make our expertise available. So, we spent some time chewing on this quandary, and we came up with an eerily familiar idea: let's create a new constellation of services that the residential design market has not really seen much of before and maybe doesn’t even want, and see how it goes. It worked with MEP engineering, so why not try it again?
Our work is with architects, contractors, and owners to help the architecture, engineering, and construction (AEC) industry look where it's going, rather than where it’s been. We recognize that the design process itself is akin to a technology that can be refined to be more efficient and effective. It’s all about relationships and information flow; “Who Says What to Whom and When?” can have tremendous and lasting influences on a project. To expand our impact in line with that perspective, we now offer even more accessible consulting for projects in the concept phase of design. We help architects map out performance outcomes when the architectural design process is still quite fluid and before owners fall in love with a design that’s not yet ready to get fully baked. This idea is simple and in line with the work that we’ve been doing for years. Our work is guided by building science principles and a deeply held ethos that buildings should help human beings thrive.
Just a short decade ago, we at Positive Energy primarily fielded inquiries from architecture and construction firms interested in our consulting and engineering services. While construction industry professionals remain the vast majority of our clientele today, in the last few years we have seen a shift in our client-base demographic with a substantial increase in inquiries from homeowners, partly because building science has exploded into the zeitgeist in the last few years.
On the whole, this is a fantastic development. In many markets across North America, Passive House remains relegated to the realm of “we don’t do that here”. The increasing frequency of owner-required efforts to achieve Passive House performance is an important shift in demand-side market behavior, because architecture firms and builders are being forced to respond. Providing support to AEC clients—helping project teams understand how close their standard strategies are to achieving Passive House and offering data and experience to help them find solutions that are both beautiful and beneficial—is Positive Energy’s tactic for building up emerging markets for Passive House in areas where its acceptance so far has been tentative.
This work is not easy, but it can be done. It’s our way of answering the question, What is our vision for the world we want to live in and leave behind for our children?
We are encouraging others—you, dear reader—to also take a stab at this work. In that spirit, we are offering up the following case studies to show how Positive Energy provided support to three projects at different scales of building size, program, and scope.
Leveraging Big Perspectives in All Projects
Consider this: what if all our homes and buildings were beautiful, durable, and low-energy-using, offering sumptuous comfort and a healthy indoor environment? Architectural design exists at the confluence of creativity and data, an intellectual space that presents hard problems to solve. What might be the best path to a high performing building may fall completely flat in the realm of inspiration. The inverse is also true — what might be an incredible feat of creative potential in form may completely lack necessary function. So how do we successfully reconcile the age-old question of form and function to create beautiful, uplifting spaces that also perform across a range of metrics that benefit occupant and planet? Enter what we at Positive Energy call Performance Consulting.
Fundamentally, Performance Consulting is a series of carefully choreographed modeling exercises intended to provide understanding of the impacts that a given environment has on a building’s performance across a range of metrics. We use quantitative analyses to facilitate this understanding, but when these analyses occur is also extremely important. In the early, conceptual phase of an architectural design process, there is tremendous value in being able to iteratively test assumptions against simulated performance data, compare design options, and make informed decisions while the design is still fluid.
The whole idea is to optimize (1) a project’s architectural strategies using objective analyses of massing, orientation, fenestration, and even seasonal daylight autonomy, glare potential, and passive thermal comfort (meaning without the aid of active HVAC systems). It’s also the right time to think critically about (2) the mechanical system concept, dimensionality, and locations of equipment and distribution components, ensuring that they all have enough space to be installed and serviced. And lastly, it’s the best time to (3) create site-level system concepts for energy (renewables/batteries/etc.) and water resources (rainwater-catchment/well-integration/filtration/storage) as our relationship to energy and water grids—and the quality, reliability, and cost of these services—rapidly evolves.
These three ontological categories of analysis are what we call Passive, Active, and Resilient Systems. When we consult with architecture firms in this way, we help check design instincts with very accessible scientific rigor. The roles we played in the following projects are not always that of a Passive House consultant, but always involved providing data to evaluate the projects’ design and specifications and see how far along—or far away—they are from Passive House-level performance. In this sense, we are an important part of a larger effort to calibrate the project relative to a known standard—Passive House.
