About Us

At Light House, we create built environments that reuse and reduce building materials, eliminate waste and greenhouse gas emissions, generate energy, support occupant health and wellness and restore nature.

We work with building owners and developers, construction professionals and general contractors to create regenerative communities and buildings that give back to the environment and promote human health and well-being. With our diverse technical expertise, we help our clients with environmental design, select and attain building certifications that meet their environmental objectives, as well as facilitate strategic visioning and planning for new projects. Our experienced team of accredited specialists has successfully guided hundreds of building projects to achieve certification under LEED, BuiltGreen, WELL, fitwel, TRUE, Living Building Challenge and other certification frameworks. We also conduct life cycle analysis and emissions calculations to support our clients’ carbon reduction goals. Our proven track record ensures our work is on time and on budget while maximizing project sustainability goals.

We are also leaders in accelerating our world to a circular built environment. We conduct advanced research on circular innovation in building policy and practice. Our seasoned team works directly with all levels of government and building industry stakeholders providing policy advice, market assessments, stakeholder facilitation and customized education programs to integrate circular thinking into the life of buildings and the communities in which they exist.
