2024 Sustainability Report

We are pleased to present our first corporate sustainability report:

Rooted in Values

A building that works better also helps people live better. Healthier air, smart HVAC & plumbing design decisions can often mean more mental clarity, productivity, and community engagement.

Our goal is to create healthy environments that have reduced energy bills and increased comfort. Serving the people and the environment is what building sustainability is all about—and making buildings work better is what we do here!

What does sustainability look like?

1. Building places that sustain life

2. Making decisions that protect the planet

3. Designing innovative solutions

It will take all of us working together with the intention of creating a safe place for future generations to thrive. This is our commitment to our employees, clients, the community, and the world.
