Green Building increases the efficiency with which buildings and their sites use energy, water, and materials.

Expertise is more than just a check box…

As a national leader in the construction of green multifamily housing, we have dedicated significant company resources to creating innovative solutions for both our clients and for our own operations. We construct buildings efficiently with careful use of time, materials, energy, money and space.

The WALSH team has delivered some of the region’s most sustainable projects, with over 160 green projects completed.

As a result of this focus on energy efficient construction practices and prior project successes, WALSH has produced buildings that attain the desired level of sustainable certification and are also delivering savings to the owner and end users.


Beginning well before the creation of the LEED and other green certification rating systems, WALSH was working with clients and their design teams to incorporate green measures into projects. These included alternative insulation materials and methods, green roofs, low-emitting materials, and highly efficient mechanical systems. With the advent of Green Certification Programs, we have worked in an integrated manner with project teams to maximize incorporation of green measures into all of our projects. To accomplish this in a productive, cost-effective manner requires that all team members work effectively within a highly collaborative process.
