One Size Does Not Fit All.

Performance-based energy efficiency codes put you in the driver’s seat. At Populus, we won’t give you just one path to compliance. You tell us your goals - we’ll deliver a menu of energy efficiency strategies that preserve the aesthetic integrity of your project as well as your budget.

More Bang For Your Buck.

Want to know how much those solar panels will shrink your carbon footprint? Interested in whether those high-performance windows will pay for themselves in energy savings? Going all the way to net-zero? Let Populus run the numbers. Using energy modeling software, we can estimate the performance of your project while it is still a stack of blueprints and provide you with the raw data to make your own decisions.

TEAM Players – "Together Everyone Achieves More".

It’s not just a corporate retreat slogan - when it comes to energy efficiency, the old adage is true. Make Populus a part of your project team and together we can find the low-hanging fruit while it is still ripe. Sometimes simple design changes can translate into deep energy use reductions. Is your duct system going to heat your attic more effectively than your bedroom? Try moving the ducts into the conditioned envelope. Will those floor-to-ceiling windows leave you shivering all winter and sweating all summer? A properly sized overhang or thoughtfully located Aspen tree could prevent both. Early identification of often-overlooked improvement opportunities saves time and prevents costly re-designs. Invite Populus to a design charette, get us involved in the process early, and you might just save a bunch of green.
