LDa’s approach to sustainability is deceptively simple: we apply common sense solutions to complex problems. In all of our work we strive to balance functional needs with the constraints of budget, schedule and aesthetics. We offer sustainable design services for new construction, renovation, interior design, and energy consulting projects of all sizes. Our goal is to create inspiring design that is conscious of its ecological footprint.

From project inception through construction to occupancy, LDa considers a broad range of ecological design drivers, including a home’s location and orientation; appropriate site development; water usage and runoff; energy consumption; low embodied energy and non-toxic materials and finishes; general indoor air quality; and the use of natural daylight and views. Our long standing commitment to sustainable design helps steer our clients’ visions into truly enduring solutions through the thoughtful application of well-researched, reliable and energy–conscious strategies.

All of our projects undergo a sustainable design analysis using LEED and/or Energy Star as the initial benchmarking tool. We also have an extensive library of green interior design approaches and ideas covering every category of a project including furnishings; upholstery and decorative fabrics; plumbing and lighting fixtures; and floor and wall finishes.


Many members of our firm are LEED accredited professionals and have worked on a number of LEED projects with different designations (NC, CI, H). LDa currently has 12 projects registered or certified with LEED. Of those not LEED registered, our projects still incorporate significant sustainable design strategies.

As an example, one of our more recent LEED for Homes (LEED-H) projects is a gut renovation of a 1906 Gambrel style Victorian home in Newton, MA. Careful attention was given to the design and construction techniques used to execute the project to achieve a non-toxic, energy-efficient home while also preserving the beautiful original exterior and interior architectural character of the residence. The front of the home preserves most original detailing and looks much as it did 100 years ago. The back of the home was given new life through a surgical interior and exterior renovation/addition which includes a fully glazed family room, open kitchen, mud room, breakfast area and new bedrooms.

All materials, details, furnishings, and fixtures in the original portion of the Newton house were either preserved or designed with traditional architectural characteristics, while in the addition a more contemporary vocabulary was used. Sustainable design features include careful orientation to take advantage of daylight and prevailing wind for ventilation; water-sipping landscape items including many native plantings; detailed construction waste management that resulted in a better than 95% recycling rate of all waste material; Forestry Stewardship Council (FSC) approved framing lumber, decking, roofing substrate, and interior finished woodwork; Energy Star appliances and light fixtures; very high efficiency plumbing fixtures; and extremely low VOC paints, adhesives and sealants.


Out of a staff of thirty-five, eleven of our employees are LEED Accredited professionals.
