MESSAGE FROM OUR CEO

We are pleased to present our first corporate sustainability report. MacDonald-Miller’s commitment to sustainability stems from our company mission to make buildings work better.

At MacDonald-Miller we are ready to zero in on carbon neutrality and ready to support building projects at every stage of their sustainability journey. As a full-service mechanical contractor with a world-class engineering team, we are proud to shape projects that influence and enhance our local communities in Washington, Oregon, and beyond. We design, build, and optimize mechanical systems that lower energy use without compromising performance.

Why are we publishing this report?

1. We hear the demand. We’re tuned in to what our clients are asking for. There’s a growing call for robust sustainability solutions in building design and operations. This demand has only intensified since the inception of Leadership in Energy and Environmental Design (LEED) nearly three decades ago, alongside the rising prominence of Environment, Social, Governance (ESG) initiatives aimed at risk mitigation. We understand that a truly resilient company goes beyond the basics, offering comprehensive services that prioritize environmental health therefore we also set ambitious sustainability goals of our own.

2. We lead by example. As of 2023, we have joined both the Climate Pledge and the MEP 2040 sustainability commitments. As a proud signatory, we are pleased to be able to share our findings publicly with our employees, peers, and customers. This report marks the culmination of our efforts in establishing a baseline for our sustainability journey.

3. We bring solutions. MacDonald-Miller Facility Solutions isn’t just a name; it’s a promise. We’re uniquely equipped to offer innovative solutions that address the challenges posed by our evolving climate and building codes. Whether you’re navigating stringent state building performance standards or simply aiming to cut down on energy costs, count on us to deliver tailored solutions that meet your needs.

Sincerely,

OUR COMMITMENT

Net Zero Carbon by 2040 for company operations and projects.

There is a place for everyone on our sustainability journey.

SUSTAINABILITY ACCELERATORS COMMITTEE

We plan, manage, track, and provide engineering assistance in executing sustainability efforts of MMFS, including MEP 2040 and Climate Pledge.

01 ENVIRONMENT

In December of 2022 we committed to net zero emissions in our facilities and operations by 2040 by becoming a signatory for the Climate Pledge. Our benchmark data from 2022 is the first step to regular reporting, carbon elimination and understanding credible offsets that will help us meet our goals.

Among the first in the building design and construction industry to demonstrate leadership in disclosure of total corporate GHG emissions, including third party evaluated Scope 3 emissions.

GOALS

1. Engage material and equipment vendors and manufacturers about reducing energy and water use throughout the value chain.

2. Transition vehicle fleet to electric and hybrid (5% by 2025, 25% by 2030).

3. Explore employee commute data; evaluate realistic reductions for gaspowered single passenger trips.

Direct Emissions

Greenhouse gas emissions affiliated with building natural gas and vehicle fleet.

Excludes refrigerant leakage for 2022

Indirect Emissions

Greenhouse gas affiliated with generation of purchased electricity for the buildings we occupy.

Value Chain Emissions

Greenhouse gases affiliated with upstream and downstream activities. Our biggest GHG emissions stem from capital goods, which is typically comprised of equipment, pipes, valves, fittings, sheet metal, and electrical materials.

Gas-powered passenger vehicles for one year. Homes’ energy use for one year. Wind turbines running for a year needed to offset these emissions.

3 calculations were performed by third-party consultant Brightworks Sustainability. Information for calculations included financial/spend based, estimations, and/or raw data.

02 CULTURE + COMMUNITY

At MacDonald-Miller Facility Solutions, our company culture is defined by a spirit of collaboration, innovation, and continuous improvement. We foster an environment where every team member feels valued, empowered, and inspired to make a difference. Our commitment to community extends beyond our workplace, as we actively engage in philanthropic initiatives, volunteer efforts, and partnerships aimed at creating positive social and environmental impacts in the communities we serve.

OUR MOTTO You be you and together we can.

The previous page demonstrates our carbon footprint, here is a summary of our positive impact – otherwise known as our handprint (1):

BUSINESS

EQUITY GOALS

We aim to include the following percentages of MWBE (Minority/ Women Owned Business Enterprises) firms across our work:

• 7% in Construction Division

• 2.5% in Building Services Division

• 10% in Corporate Services

Why is culture and community so important to sustainability?

From our experience, the most successful, innovative, and impactful projects are comprised of folks that look out for one another.

Life happens. Family members get sick, mouths need to get fed, and bills need to be paid. Having each other’s backs is in our blood – and doing so means we can all keep showing up to be our best selves.

We truly believe that when we sustain our community (that’s all of you too) then we sustain your buildings.

GLOSSARY

How MMFS defines the following sustainability terms. Energy Use Intensity (EUI) ) Metric used to indicate a building’s energy performance compared to size. Annual energy use divided by conditioned gross square footage (kBTUs/square feet/year). Typically excludes parking area.

Lower EUI demonstrates less energy used.

Greenhouse Gases (GHG) There are six (6) according to the GHG Protocol Corporate Standard (revised edition) – Carbon Dioxide (CO2 ), Methane (CH4 ), Nitrous Oxide (N2O), Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs), and Sulfur Hexafluoride (SF6 ). Typically expressed in CO2 equivalents (CO2e). Note – this list is not all inclusive.

Net Zero Carbon (by 2040) For the purposes of the Climate Pledge, driving down to zero relevant GHG emissions affiliated with our corporate operations (Scopes 1–3), measured over 12 consecutive months. This involves electrification of company assets, value chain efficiencies, transition of our energy grid to carbon-free fuel sources, and eventual credible offsetting. The GHGs are translated into the same unit of measurement (metric tons of carbon dioxide equivalence, or MT CO2e).
