Owner-operators, not consultants

Built by owners, for owners

We developed our energy analysis methodology for our own multifamily portfolio — then made it available to every owner and operator.

Our story

From portfolio problem to platform

Arnold Energy is the energy consulting practice of Arnold Development Group (ADG), a multifamily real estate firm that acquires, repositions, and manages apartment communities across multiple markets.

We built our energy analysis methodology for our own portfolio first. When we saw the impact — reduced operating expenses, increased property value, and better-performing buildings — we decided to make it available to other owners and operators.

A professional energy analysis used to cost $5,000–$15,000 and take weeks. We've streamlined the process so it takes minutes of your time, and your first property is analyzed free.

What sets us apart

Principles that drive every recommendation

Financial accretiveness first

Every recommendation must reduce operating expenses or increase NOI on a risk-adjusted basis. If it doesn't improve your bottom line, we don't recommend it.

Real dollars only

No social cost of carbon, no "avoided emissions value," no "green premium." Every savings number corresponds to a real utility bill reduction or tax credit dollar.

Objective advice

We don't sell equipment, install solar panels, or earn referral fees. Our only product is analysis and advice — we succeed when your buildings perform better.

Conservative assumptions

We use low-end savings estimates and high-end cost estimates. You get honest ranges, not false precision designed to oversell a project.
