The term “net-zero” of ten brings to mind big budgets and exp ensive building systems, but this c onc eption c ouldn't b e fur ther from the truth. As archite cts and engine ers, we have ever y thing we ne e d to design net-zero ready buildings for the same c ost as buildings that me et basic c o de All it takes is the right mindset and the right approach.

How to design net-zero ready buildings on a budget - AIA
Here’s what our team archite cts from emersion DESIGN and engine ers from Fanning Howey learne d while c ollab orating on a net-zero ready campus addition for B ethany Scho ol in Cincinnati, Ohio:
B e aware of p otential funding sourc es for high p er forming buildings. D ep ending on the marketplac e and the typ e of client, there may b e funding in the form of tax breaks, grants or rebates. Make sure to include these additional funding sourc es in your analysis of first c osts and long-term op erating c osts.
Make sure the owner is all in
Test , retest , and c ontinuously improve
Like all goals, creating a net-zero ready building will not happ en without buy in from all par ties, esp e cially the owner D esigners should e ducate owners ab out the af fordability and practicality of netzero strate gies However, if net-zero isn’t c entral to a client's mission and goals for the proje ct, then net-zero strate gies are unlikely to b e embrac e d and actualize d B ethany Scho ol’s strong existing c ommitment to sustainability made it p ossible for us to deliver a net-zero ready design at $225 p er square fo ot.

Assemble the right design team
Even if you don’t have a sustainable-minde d client like B ethany Scho ol, you can still improve the overall energy ef ficiency of your designs. Star ting down the path of designing for net-zero ready buildings will help se cure the future of your practic e and the planet.
To develop a net-zero ready design you ne e d a team with a c ollab orative mindset. Archite cts and engine ers ne e d to b e c omfor table sharing ideas and working outside of their given disciplines. This is imp or tant b e cause net-zero ready buildings re quire extreme creativity and laser-fo cuse d at tention to the sp e cifics of each building and site.

From the ver y b e ginning, ever y B ethany Scho ol proje ct team memb er was in the ro om giving input B efore there was even a flo or plan, the team explore d seven dif ferent window-to-wall ratio profiles and multiple c onstruction profiles, including glazing and solar c o ef ficients, evaluating along with way with energy mo deling data Working c ollab oratively and drawing on the strengths of all involve d is the only way to create a c ost-ef fe ctive, net-zero ready building

D on't be c onstraine d by rules of thumb
Net-zero ready buildings re quire p er fe ctly-size d systems to b e c ost-ef fe ctive, and they can’t b e prop erly designe d by following traditional rules of thumb. During early c onc eptual design ef for ts, the entire team ne e ds to explore building-and site-sp e cific solutions using energy mo deling to ols. For example, c onventional wisdom says that a high p er forming building should have more glazing on the south than the nor th. But during the energy mo deling pro c ess for B ethany Scho ol, our team found the opp osite to b e true. For this building, on this site, more glazing on the nor th meant fewer glare issues while less glazing on the south meant less heat gain and the ability to eliminate solar shades.
