How Do You Run a Sustainable Business?
Professionals from around the world tell us how they make their practices sustainable and what challenges they face
As the industry and its clients become more environmentally aware, remodeling and design businesses are looking to incorporate sustainability into their projects. We asked professionals around the world how they run their businesses sustainably, what they’ve learned along the way and what challenges they face.
This office of German construction engineer Dag Schaffarczyk of Spreeplan Projekt UG was renovated with sustainability in mind.
Pros Bring Sustainability to Their Offices and Homes
One of the best ways to showcase sustainable design and building practices is to use them yourself, pros told us. For example, Australian architect Marc Bernstein of Melbourne Design Studios is building his own home — a passive house that will produce more energy than it expends every year. When completed, it will be used as a show home and workshop space for educating the public on sustainable architecture.
“I think it is super important that a business walks the walk,” Bernstein says. “We always try to set an example that inspires our clients and that leads the way. Otherwise how can we expect our clients [to want] to do the right thing?”
German construction engineer Dag Schaffarczyk of Spreeplan Projekt UG has incorporated sustainable techniques into his office (pictured) in a 1911 building his firm renovated. “In this renovation we have fundamentally sought to reuse or keep existing features like the roof tiles and wooden frameworks,” Schaffarczyk says. “Instead of conventional building materials, we used natural materials like straw panels, clay- and lime-based plaster, hemp insulation, granulated cork panels, lime wash paint and regionally grown oak.
“All spaces are heated with radiant heating panels in the walls and floors,” he continues. “The heating [in the office] draws on the return of the heating system from the whole building. Cooling works on the same principle. … Our office is our show home.”

Chacón, of the Spanish architecture firm, has also addressed sustainability at the office. “[We use] renewable energy for the electricity we consume in the studio, [and] recycled paper and sustainable products,” she says. “We also have a responsible recycling program for paper, toner, consumables. We reduce unnecessary material.”
Her approach to sustainability also goes beyond the physical boundaries of the office. “We have also created our own low-impact transport policy: We and our collaborators [live] within a limited distance of the studio, or we agree to use a bicycle or public transport, and we had an online system to facilitate remote work even before the pandemic,” she says. “We apply a fair salary policy, and we recognize the work of our collaborators. This is also sustainability.”
One way French interior designer Mayssa El Fakir of interior design studio Ouvrage works toward sustainability is by limiting her firm’s use of samples. “Rather than asking for samples to be made for each client, we hold onto them and we are trying to create a materials library in order to reuse them as much as possible,” she says. “We also select French suppliers in order to limit the carbon impact of transportation. Likewise, we try to avoid buying electronic equipment, and either rent it or buy it refurbished to ensure that it has a long life.”
As many of us work from home, rather than in our offices, through this continuing pandemic, Houzz Pro business management software can help you easily stay in touch with clients remotely. Houzz Pro corrals all of your communication, documents and client approvals for each project in one centralized place, which you can easily refer back to at any time.

How Pros Incorporate Sustainability Into Their Projects
When seeking ways to bring greater sustainability to their design or remodeling projects, many of the professionals we interviewed turn to existing sustainability frameworks. “We apply our own methodology based on the highest level of certification standards, such as Passivhaus and Breeam,” Chacón says, referring to two internationally recognized sustainability certifications. “Whether or not the aim is to have the project certified, sticking to these requirements throughout the design and construction process necessarily leads to the most sustainable project possible, given the location and needs of the client.”
Others combine existing standards with their own unique approaches. “Most of our projects these days are actually going down the passive house … route,” says Bernstein, the Australian architect. “It also looks at issues like health and comfort and condensation, etc., so it is really quite a holistic tool. We then combine that with our ‘DEEP’ methodology, that we have developed in-house over the years … to inform and fine-tune the design even way before starting to specify sustainable materials.”
French architect Tina Merkes says this: “Whenever possible, push further at the level of systems,” for example, recycling rainwater for use in the washroom, heat pumps and other approaches. She also notes that it’s important “to work with companies that are sensible to sustainable development.”
El Fakir, the French interior designer, and her studio take a similar approach. “We see it as a point of honor to use vintage or second-hand furniture, since it’s much easier to find than it used to be,” she says.

Recycling is a big emphasis for Kloeden, the British architect. For one project, she is trying to find buyers for a large amount of old furniture the owners don’t want to keep. “We also have a studio policy of avoiding nonrecyclable materials in our specifications wherever possible,” she says. “I have always done this implicitly, as it is my deeply ingrained design ethos, but as the team grows, the next step is to document the policy and develop an internal checklist when we specify finishes for our projects.”
For Barbara Milner of Canadian design firm South Hill Interiors, it’s about knowing her stuff. “I keep myself up to date on new products and always offer clients a variety of options.” This has become a point of differentiation in the client experience and expertise she offers. “Not everyone is inclined to spend the time required to understand the science,” she says.

How Pros Source Products Sustainably
Of course, materials have a significant impact in terms of making a project more or less sustainable. And many of the pros we spoke with shared their love of wood. “We build with an increasingly high percentage of natural materials — we are wood geeks especially,” Chacón says.
“The wood we use … is made from domestic timber from nearby mountains,” says Sanada, of the Japanese architecture firm. “Wood and stone are sourced in continuous collaboration with local lumber mills and masons.”
Eto, also a Japanese architect, advises that fellow pros “use a lot of natural finishes and insulation materials.”
“It is not just a matter of choosing this or that material or product, but of how it fits into the construction as a whole and what ‘history’ it contributes to the … life cycle of the building you are going to create,” Chacón, the Spanish pro, says. She works to reduce impacts at all stages and shares the following about her approach:

She works to reduce impacts at all stages and shares the following about her approach:
- Location: “Reducing the impact of transportation, promoting local culture and economy, recovering craftsmanship that’s disappearing.”
- Manufacturing: “It is always better to use a material, like many wood products, that has a positive impact on the environment.”
- Construction: “We want products that have a minimal footprint, that cost almost no energy or water to use on-site, and that do not contribute to air pollution.”
- Use: “Low-maintenance, nontoxic materials that contribute to a healthy environment.”
- Disposal: “Use materials that are designed to return to natural cycles, transforming into other materials or energy.”
Bernstein, the Australian architect, also takes a holistic approach, thoroughly researching production chains, analyzing embodied energy and looking at cradle-to-cradle factors. “What happens with the product after its life in this building? And can it be recycled or upcycled into something new? In Australia, our buildings generally have a much [shorter] lifespan than, say, in Europe, and so recycling at the end of its lifespan becomes a really important consideration,” he says.
“And last but not least, a sustainable product should always be good for both the environment and for your health,” Bernstein adds. “So, for example, when designing [cabinetry] and specifying furniture for our clients’ homes, we would always make sure we specify low-emission materials. … Where possible, we like to include planting into our designs, as there are some plants that can cleanse the air, and remove the small quantities of what’s left in terms of off-gassing — a really cheap but great way to make a home more sustainable.”
Sanada of Japan and Milner of Canada both noted that it’s important to keep abreast of new developments. “My clients are always interested in the latest innovations, and I am finding that now, more than ever, sustainable products are becoming sought after and considered despite the premium price point that is often a reality when it comes to products of this nature,” Milner says.
However, that doesn’t mean sustainable materials are hard to find. “There are companies that only produce natural products and others that have organic lines on the side,” says Italian architect Maria Elisa Villa. “For installers it is a bit more difficult: Either you know them, or the company has teams [it can recommend] or you find someone who is able to follow your lead.”

How Pros Advocate Sustainable Solutions to Clients (or Not)
While design and remodeling professionals may have strong beliefs about sustainability, clients don’t always share them. We asked pros to tell us if they advocate for sustainable solutions in clients’ projects, and if so, how.
“We believe that it is our responsibility as creative technical [experts] to contribute to making society aware of the serious global environmental problem, and to help our clients assess possible solutions and make the best decisions,” Chacón says.
El Fakir thinks along the same lines. “We also do a huge amount of education work, explaining that using quality materials that last over time and can be passed on is interesting not only for resale, but also if you hope to pass your property on to your children,” she says.
Kloeden, the British architect, has faced resistance to sustainable solutions from some clients. “From time to time, we come across clients who want their home to look exactly as it was on Day 1 post-renovation. For this type of client, this means synthetic materials,” she says. “The temptation is to let them have what they want, as we are always short on time, but this is the area close to our heart, so it’s worth taking the time to educate the clients.”
Indeed, client education is part of running a sustainable business for many pros. “We always try to push boundaries, not against our clients, but as a team effort together with them,” Bernstein says. “At the end of the day, we want them to arrive at a home that is better than what they had expected, that is suited to their lifestyle and that is greener and more sustainable than what they had asked for.”

On the other hand, Villa, the Italian architect, notes that it may be necessary to compromise with clients who may not be sustainably minded. Her philosophy is that a little is better than nothing.
Schaffarczyk finds that he does not usually need to advocate. “Our clients know what they’re getting into when they come to us. As a rule, they are only surprised by what we can achieve with our sustainable and healthy builds. We often hear, ‘If only I’d known sooner.’”
Milner also sees more interest in sustainable builds from the client side these days. “There are more conversations about sustainable products happening at the construction stages of projects. There’s an increasing desire to build responsibly and to achieve a ‘healthy’ end product,” she says. “When it comes to renovations, the desire to replace dated products with long-lasting smart options often leads to discussions about durability as well as wellness factors like VOCs. As a result, conversations about how a product is manufactured have become less uncommon, and that often brings attention to the sustainability of a product. Once people understand how a product is made, price no longer becomes the one and only driving factor.”

Pros Reveal Challenges in Making Their Work More Sustainable
Although sustainability is increasingly part of the conversation in design and remodeling, that doesn’t mean it’s a given at all. Pros face many challenges in attempting to achieve projects and ways of working that are truly sustainable.
“Traditionally, the construction industry and a lot of its workers are not particularly known for an interest in ‘green stuff,’ so getting everyone on board even for simple things like separating construction waste into different bins to allow recycling on-site can sometimes be hard,” Bernstein says. “But it is one step at a time, and I find the industry is finally starting to embrace these changes — again, it just needs a few of us to lead the way, I think.”
“The challenges are cultural and unfortunately economic,” Italian architect Fulvio Claudio Melle of Melle-Metzen Architects says. “Not always, but sustainable products are slightly more expensive.”
Merkes agrees. “All of the steps require more research time on the part of the architect than an average project with standard products … but this is positive, productive time.”

“The offerings in terms of technical equipment, especially for the kitchen, are still very limited, and it is difficult to find environmentally friendly solutions,” El Fakir says. “If we’re not working with artisanal custom or luxury work, it’s very hard. Options for ready-to-use materials and finishes are also limited.”
“For our construction methods, there are no standards like in conventional construction,” Schaffarczyk says. “It takes a lot of effort to source materials, and specialized craftsmen … sometimes have to travel in from far away. The effort involved in planning is a lot higher. This increases project costs.
“But this is balanced out over the years, because the costs of heating and electricity, whether for air conditioning or HVAC, will be drastically reduced. In our office building, we’ve lowered the [running costs] by 71.8%. And that’s not counting the improved indoor climate free of harmful chemicals.”

Has the Pandemic Changed How Pros Approach Sustainability?
Most of the pros we spoke with have been working sustainably for years. While the pandemic didn’t shift their own priorities, some have found their approach especially relevant. “Our mantra, ‘Architecture that connects with heaven and earth,’ has turned out to make more sense today than ever,” Chacón says.
“With COVID-19, we’ve probably been ‘greener’ than before — [fewer] miles on the road, no heating, cooling, etc., and extra office space, as we’ve all been working from home,” Bernstein says. “Other than that, I find that, while sustainability has lost some of its media focus during the pandemic, people still think about it. Almost all of our clients want to do the right thing, and that is always encouraging and inspires us to create a better home for and a better world with them.”
“On an intellectual level, [it’s given us] the time to ask the right questions about the planet, our future, questioning our way of life,” Merkes says.

When asked about how they work toward sustainability, the pros we interviewed emphasized distinct approaches, reflecting the many ways to improve sustainability. “Use natural energy with as little reliance on fossil fuels as possible,” says Daisuke Sanada of Japanese firm Suwa Architects + Engineers. “The materials we use should be [compostable] and of natural origin as much as possible.”
“Implement solutions that lead directly to reducing energy and [carbon dioxide] emissions, spurring forest revitalization and reducing petroleum-based waste,” says Japanese architect Mariko Eto of Sola Architecture Design Studio.
British architect Yoko Kloeden approaches the problem from another angle. “To be a sustainable business, the business has to be profitable. … Those builders who cut corners always resort to nonsustainable options, as they feel they cannot be profitable without cutting corners.”
“There are different ways to make a business sustainable,” says Eva Chacón of Spanish firm Bonsai Arquitectos. “The important thing is that we are all aware of the need to do things differently, and that every person contributes their grain of sand.”
