Independent consulting that brings together sustainable energy and design for the spaces where people live and work.

Isolated systems underperform. We design them to work in concert so that your space works for you.

We model your site, usage, and goals before recommending any system. The right solution isn't always the most expensive one, or the one a vendor has in stock.

Connected systems should make your space easier to manage, not harder. We design integrations that are genuinely useful, not tech for its own sake.

Heating and cooling account for the majority of a building's energy use. We specify systems that perform year-round without inflating your bill.

Grid outages, extreme weather, rising energy costs: the conditions are predictable even when the timing isn't. We build for them from the start.
See these principles at work:
Independent design and management across the full building stack
Solar, geothermal, and battery systems sized and specified for your site
Smart systems that give you real visibility and control over your space
Heat pump and HVAC design that cuts costs without cutting comfort
Custom layouts and built-ins designed around how you actually use your space
Future-proofing your property against outages, climate, and changing needs
Layered lighting design that's functional, efficient, and tuned to the space
Straight answers to the questions we hear most.
Most building owners don't know what they need until a vendor tells them, a built-in conflict of interest. We provide independent analysis so the recommendation always starts with your building, not a product catalog.
We do. OLS manages vendor selection, coordinates timelines, and provides on-site or remote oversight through installation and commissioning. You get one point of contact who isn't on the vendor's payroll.
We primarily operate in NY (Adirondacks, Capital Region, NYC), VT, NJ, and PA and are available for remote consulting beyond the region
Shared systems, split incentives, and board approval cycles make multifamily projects fundamentally different from single-family work. We scope and present projects in a way that works for committees, not just individual owners.
Yes. It's a no-obligation call to understand your space, goals, and constraints. You'll leave with clarity on what's possible and what isn't.
We provide itemized estimates tailored to your project scope, with pricing broken out by phase so you can budget clearly and commit incrementally.
We keep the process simple and transparent. No jargon, no surprises, just clear steps from the moment you reach out to the day your system is running.
We start with a no-obligation call to understand your space, goals, and constraints. You'll leave with clarity on what's possible and what isn't.
We evaluate your site, remotely or in person, to develop a realistic scope. This includes energy analysis, system sizing, and design feasibility.
You receive a tailored design plan: system specs, layout drawings, vendor recommendations, and a phased approach you can budget against.
We coordinate vendors, manage timelines, and stay on-site or on-call through installation and commissioning. You don't have to manage the complexity alone.
