Our Team

BuildGreen Solutions partners and staff offer strong experience in a host of disciplines, with backgrounds in development, conservation, business, law, engineering, carbon accounting, facilitation, and education.  We work with clients to assemble focused teams to achieve triple bottom line results.

Scott Demark

Scott DemarkScott leads BuildGreen’s community-scale engagements, where he focuses on dramatically reducing carbon footprints through cost-effective efficiency strategies and innovative community energy solutions.  He facilitates integrated design processes, works with clients to implement sustainable design strategies, and is a green economics educator.  A civil engineer by training, he is the most technical partner in BuildGreen, and is relied upon to interpret and comment on the mechanical and electrical aspects of our projects and is actively involved with renewable energy projects.

Scott is also a green project manager for our parent company, Windmill Developments, where he has the opportunity to implement solutions that he advocates for our clients. Within BuildGreen, Scott is responsible for the “back of house” operations, thriving in his sea of spreadsheets.

Before joining BuildGreen, Scott worked for a leading engineering consulting firm where he managed the green building offerings for the National Capital region.  His projects ranged from a LEED Platinum interior fit-up to sustainable infrastructure and energy planning for new communities.  Scott also worked to implement sustainability practices in Field Operations for the Otis Elevator Company for more than 10 years, culminating in the position of Director of Environment, Health and Safety covering Canada and the Midwest US.

Scott teaches Green Development Economics to 4th year architecture students at Carleton University. An accomplished facilitator, he frequently speaks and participates in workshops on sustainability issues.

Scott and his family are steadily decreasing their carbon footprint. They aim to eat low on the food chain, as locally as possible, and seasonally from their shared neighbourhood organic garden and a local CSA.  Scott’s family lives in central Ottawa, a short walk or bike from all of their needs, where they live in a fully renovated 1919 house, a showcase of sustainable design and technologies.

Jamie James

Jamie joined Windmill Developments and BuildGreen Solutions as a partner in 2005, bringing with him specific, hands-on experience implementing energy efficiency and environmental performance in multi-unit condominium developments. Jamie currently implements clean infrastructure in Windmill projects and with other developers through BuildGreen — in some cases, collaborating with private utility providers. He also focuses on creating green building and technology financing instruments.

Since 2003, Jamie has been a sustainability advisor to Tridel, Toronto’s largest condominium builder, and has contributed to the company’s transition to become a green builder with over 6 million square feet in development or under construction in LEED candidate projects. Working with the Toronto Atmospheric Fund and Tridel, Jamie helped to develop a scaleable incremental cost financing mechanism for green, energy efficient highrise condominium construction in Toronto.

Jamie also worked for two years at Columbia University’s Earth Institute, where he developed continuing education programs on sustainability. He has consulted for the United Nations Development Programme on public-private partnerships for urban environmental services (waste, energy, water) in developing countries and on greenhouse gas mitigation financing. Before that, he worked with Trexler and Associates, a consulting firm responsible for developing greenhouse gas reduction, mitigation and offset projects for corporate and governmental clients. And in the mid-1990′s he lived in the highlands of Papua New Guinea on sustainable micro-enterprise development initiatives with indigenous landowners of a large biodiversity rainforest heritage area.

Jamie serves on the Board of Directors of the Canada Green Building Council and Co-Chairs the CaGBC’s LEED for Neighborhood Developments Core Committee. He also serves on the Board of Directors of Bioregional North America, the group responsible for implementing One Planet Living Communities in North America.

Jamie lives in Montreal with his wife and three children.

Jonathan Westeinde

Jonathan is the founder and managing partner of the Windmill Development Group, one of Canada’s most well-known and accomplished green building developers.

The company’s first five buildings have earned LEED Platinum ratings, an unprecedented track record in the industry. His contributions to these projects have been fundamental to their success: from identifying potential project partners and sites, to assembling design teams and leading creative processes; creating pro formas, working with financing partners and managing risks; to managing the sales and marketing and attracting public attention to his developments’ potential and accomplishments.  As an original design team member for Windmill’s precedent-setting development in Victoria, Dockside Green, Jonathan’s creative input and strong leadership helped drive the process.

Under Jonathan’s leadership, Windmill has expanded its portfolio of services to enable the company to provide advice to others, integrate renewable energy into projects, and green existing buildings.  He acquired BuildGreen Solutions and helped create its current partnership structure to strengthen its offerings.  He added micro-utility services to enhance Windmill’s scope of services and facilitate financing of renewable energy components of projects.  And his newest initiative, Ledcor Renew, formed with the Ledcor Group, focuses on green building retrofits.

He is committed to growing and nurturing the green buildings marketplace in Canada, and demonstrates this commitment through a wide variety of volunteer and board positions.  Jonathan is a former board member of the Canada Green Building Council and is active in speaking at conferences and other events to share his green building experience. Jonathan is also the Chair of the Centre for Environmental Cooperation’s Green Building Advisory Council, a NAFTA initiative aiming to provide an integrated green building strategy for Canada, USA and Mexico. Jonathan also is involved as a volunteer with various non-profit green building initiatives.

Jonathan was recognized as one of the Top 40 under 40 by the Ottawa Business Journal in 2006, in his hometown of Ottawa, Canada.

Rodney Wilts

Rodney WiltsInspired by his lifelong passion for the outdoors, Rodney Wilts has committed his career to improving the environmental performance of our built environment.

As a BuildGreen partner Rodney brings a depth of experience on green building materials, community scale development projects, and low-cost sustainable solutions. He has led projects as diverse as Sustainability Action Planning for One Planet Communities, developing training materials for municipal development approvals staff and project managing deep green sustainability retrofits.

Rodney’s keen interest in combining environmental issues and entrepreneurship first manifested itself in the opening of a bug zoo at eight years old. He helped pay his way through law school by leading teams of scientists through the threatened Walbran Valley to search for endangered species. His career began in earnest as an environmental lawyer focused primarily on green buildings and smart growth issues at West Coast Environmental Law. Restless with the slow pace of change in policy work, Rodney left the law to start Canada’s first green building supply centre, The Healthiest Home and Building Supplies.

Through The Healthiest Home, Rodney had the opportunity to be involved in hundreds of projects across the country, including some of Canada’s first LEED projects. He gained first-hand experience with a wide range of green materials in the field, and earned an appreciation for careful attention to the economic bottom line. The company grew and was profitable every year under Rodney’s leadership. It was while at The Healthiest Home that Rodney began working with Windmill Developments, a collaboration that continues today.

After sale of the business Rodney joined with Greg Searle to found BioRegional North America and bring the One Planet Communities program to Canada and the US. Through this experience Rodney had the invaluable opportunity to work on some of the first large-scale projects aiming to be carbon neutral from operations and taking a holistic approach to sustainability. Rodney is sharing this experience as a member of the Canada Green Building Council’s core committee on LEED for Neighbourhood Developments.

Inspired by Windmill Developments collaborations, including the LEED Platinum Vento project and early conceptual work on Dockside Green, Rodney decided to make the leap to be a full time Partner with BuildGreen. As a Partner he applies his decade of experience working on green buildings, and his lifelong passion for the environment—not to mention a Dutch heritage committed to low-costs—to innovative sustainability solutions.

Rodney is an active contributor to his community of Chelsea and can often be seen paddling his two girls in his prospector canoe, or racing down backcountry cross country ski trails in Gatineau Park.
