What we do

Six disciplines.
One goal: less waste.

From concept to commissioning, our teams integrate mechanical, electrical and digital systems into projects that pay themselves back.

Energy Efficiency

Audits, retrofits and monitoring that cut consumption by up to 40%.

HVAC Engineering

High-performance heating, ventilation and cooling for any scale.

Water Management

Smart metering, recovery and treatment for responsible use.

Green Energy

Solar, wind and storage systems designed, installed and optimized.

Home Performance Audits

Whole-home assessments that find leaks, gaps and comfort issues.

Radon Testing

Our approach

Data first.
Nature always.

Every Greendian project begins with measurement. We instrument what exists, model what's possible, then deliver systems that keep proving their value long after commissioning.
