Building science meets environmental expertise

We combine deep technical knowledge in building performance with international environmental consulting experience to deliver results that matter.

Our Story

Built on a foundation of expertise

Sunesco was founded with a clear mission: bring the same rigorous, science-based approach used in international development projects to the local building performance market.

Our founder spent years working on complex environmental and social risk management projects for multilateral development banks — World Bank, European Investment Bank, African Development Bank — learning what it takes to meet the highest standards of technical excellence and accountability.

That experience now drives how we approach every home energy audit and commercial building assessment. We don't cut corners. We use diagnostic testing to understand what's actually happening. We document our findings clearly. And we stand behind our work.

Whether you're a homeowner trying to figure out why your energy bills keep climbing, or a property manager navigating DC's building performance standards, you get the same commitment to quality.

Our Mission

Making buildings work better for people and the planet

We believe every building — from single-family homes to commercial towers — can be more comfortable, more efficient, and more sustainable. Our job is to show you how, then make it happen.

Diagnostic Rigor
We test, measure, and verify. Data drives decisions.
Integrity First
We recommend what you need, not what maximizes our revenue.
Results Matter
Post-work testing confirms we delivered what we promised.

Our Approach

How we work differently

Principles that guide every project we take on.

Diagnose Before Prescribing
We never recommend work without understanding the problem first. Blower door testing, thermal imaging, and combustion safety analysis tell us what's actually happening.
Document Everything
Every finding, every measurement, every recommendation — clearly documented with photos and data. You see exactly what we see.
Prioritize by Impact
Not everything matters equally. We help you understand which improvements deliver the most comfort and savings per dollar spent.
Verify Results
After work is complete, we test again. Post-work diagnostics confirm air leakage was reduced and safety standards are met.
