Green Building 101: How MacCoy Home Solutions Recycles & Repurposes Materials
Here is the reality most contractors do not talk about: a typical whole-home remodel can generate thousands of pounds of material — much of it headed straight to a landfill. The EPA estimates that construction and demolition debris accounts for more than 600 million tons of waste in the United States every single year — more than twice the amount of municipal solid waste generated by all U.S. households combined.
Now, here is the question homeowners often ask us: Does building green mean paying more?
Not the way we do it. MacCoy Home Solutions is a Built Green–aligned general contractor serving Snohomish and King Counties. Our projects emphasize waste reduction, responsible material sourcing, and energy-efficient construction practices. In many cases, recycling materials and minimizing demolition waste can lower disposal costs while improving the home’s long-term efficiency. During the estimating process, we walk clients through these options transparently so they can decide which sustainable choices make the most sense for their project.
This post breaks down exactly what green building means in the context of a real remodel or rebuild, how MacCoy manages materials from demo day through final walkthrough, and where the financial upside actually lives.
What 'Green Building' Actually Means — in Plain Language
Green building is a construction approach that minimizes environmental impact through resource efficiency, waste reduction, sustainable material sourcing, and energy-conscious design. What it is not is a premium upgrade tier or a niche specialty reserved for new construction.
Remodels, additions, and full rebuilds are among the highest-impact applications of green building practices — precisely because demolition and construction generate so much waste, and material decisions at the design stage have long-term downstream consequences.
MacCoy Home Solutions is a Built Green member contractor serving the Pacific Northwest, participating in one of the region’s most widely recognized residential green building programs. Built Green projects are evaluated using a comprehensive, point-based checklist that measures energy efficiency, water conservation, responsible material use, and indoor environmental quality. These principles closely align with national sustainability frameworks supported by the National Association of Home Builders, including the ICC-700 2020 National Green Building Standard, which guides responsible residential construction.
Green building is also increasingly code-required in Washington State. New ADU construction, ground-up builds, and major additions must comply with the Washington State Energy Code (WSEC), meaning energy efficiency standards are not optional for these project types. MacCoy builds to code as a baseline and, on qualifying projects, goes further.
How MacCoy Reduces Waste on Every Job Site
When a remodel or rebuild begins, the first thing most contractors think about is speed. The first thing MacCoy thinks about is sorting.
Before a single load leaves the job site, the MacCoy team separates salvageable materials from genuine waste. This is not a feel-good exercise — it is a disciplined process that reduces disposal costs and keeps usable material out of the landfill.
What Gets Diverted and Where It Goes
- Lumber and framing: Usable-length pieces retained for blocking, backing, and structural framing within the same project — reducing new material orders.
- Fixtures and hardware: Intact plumbing fixtures, light fixtures, cabinet hardware, and interior doors are evaluated before demo. Items in serviceable condition are offered to the homeowner for reuse or donated to organizations such as Habitat for Humanity ReStores.
- Concrete and masonry: Broken concrete and masonry aggregate from foundations or hardscaping can often be repurposed as grading fill or driveway base material on the same lot — eliminating both a disposal trip and a material delivery.
- Drywall: Clean off-cuts from the new installation are separated from contaminated demo waste. Where local specialty recyclers accept clean drywall, MacCoy identifies and uses those facilities.
According to the U.S. Environmental Protection Agency, many materials generated during construction and demolition — including concrete, metals, wood, and drywall — can be recovered and reused rather than sent to landfills. Industry estimates suggest that as much as 90 percent of C&D waste is technically recyclable, but the gap between potential and reality often comes down to whether the contractor installs a system to separate and recycle materials. At MacCoy Home Solutions, that process is built into how we manage every project.
Sustainable Material Sourcing: What MacCoy Looks for Before Ordering
Waste diversion addresses what leaves the job site. Sustainable sourcing addresses what arrives.
When MacCoy specifies materials for a project, we evaluate three things: recycled content, regional sourcing, and long-term durability. A material that lasts 40 years is inherently more sustainable than one that needs to be replaced in 15 years.
Materials We Prioritize for Pacific Northwest Builds
- Engineered lumber (LVL beams, I-joists): Uses significantly less virgin wood than dimensional lumber, performs more consistently, and reduces waste from warping and defects.
- Fiber cement siding (HardiePlank and similar): Durable, moisture-resistant — ideal for the PNW climate — and manufactured with recycled content. Fiber cement products like HardiePlank carry manufacturer warranties of up to 30 years, compared to 15–20 years for typical wood siding, making them a longer-lasting choice for the Pacific Northwest’s wet climate.
- Reclaimed wood accents: Beams, mantels, and feature walls sourced from regional salvage suppliers. Character material that cannot be replicated with new-growth wood, and avoids the embodied carbon of new manufacturing — a meaningful reduction compared to virgin-harvested lumber.
- Low-VOC paints, adhesives, and finishes: Indoor air quality is especially important in well-sealed, energy-efficient homes with controlled ventilation. Low-VOC products protect both the occupants and the installers.
- ENERGY STAR-rated windows and appliances: Performance-certified products that meet EPA and Department of Energy efficiency standards. Better windows alone can meaningfully reduce heating and cooling loads in a PNW home. See Energy.gov’s guidance on energy-efficient materials.
Material choices made during the design phase — before permits are submitted — have the greatest cost and sustainability impact. MacCoy integrates these decisions early, not as an afterthought once framing is underway.
Does Green Building Actually Save You Money?
Let us address the objection directly. Yes, some green upgrades carry a modest upfront cost. But the majority of green building practices on a remodel or rebuild are either cost-neutral or produce measurable savings — and the financial picture changes significantly when you look beyond the first invoice.
Where the Savings Show Up
- Waste diversion reduces dumpster and disposal fees. On a full home remodel or ground-up rebuild, fewer haul-away loads translate directly to hard cost savings.
- Reclaimed materials used for accent features — beams, flooring, shiplap — can replace or reduce spending on new material orders for those elements, often at comparable or lower cost when sourced regionally.
- Energy.gov estimates that proper air sealing and insulation can reduce a home’s heating and cooling costs by up to 30 percent annually, depending on existing insulation levels, home size, and climate zone. In a Pacific Northwest home where heating season runs six months, that is a real number.
- Snohomish PUD and Puget Sound Energy both offer rebates for qualifying energy-efficient upgrades, including insulation, windows, and HVAC equipment. MacCoy advises homeowners on rebate eligibility during the design phase, before specifications are locked.
- Resale value: NAHB research suggests green-certified homes may command a resale premium in markets with strong buyer awareness of energy performance — a growing trend in the Seattle metro area, where buyers increasingly ask about certifications, utility costs, and building performance.
There is also a less obvious financial benefit: the planning discipline required by green building tends to reduce change orders. A contractor who carefully considers material specifications before permits are pulled is one who does not surprise you mid-build with cost revisions.
Where Green Building Shows Up in a MacCoy Project
Green building is not a separate service tier at MacCoy Home Solutions — it is part of how every project is managed. Here is what that looks like across our core services.
- Full home remodels and kitchen/bath renovations: Demo waste separation, low-VOC finishes, ENERGY STAR appliance integration, and reclaimed accent materials are standard considerations on every interior remodeling project.
- ADU and DADU builds: Washington State Energy Code compliance is required by law on new ADU construction. MacCoy builds to code and discusses Built Green options with every ADU client. Learn more about our ADU and additional services.
- Ground-up custom home builds: Full demolition waste management planning begins before the first shovel breaks ground. Structural material selection is integrated into the design phase. In Built Green-certified builds, energy performance is formally modeled before permits are submitted. See our full ground-up build services.
MacCoy’s Built Green certification means these practices are not self-reported — they are scored and documented on qualifying projects. Homeowners receive a record of the sustainability practices applied to their build, which can be relevant for resale documentation, appraisal reports, and permit archives.
