About Taitem Engineering


“Taitem” is short for “technology as if the Earth mattered.” That concept underpins all the work they do as a consulting firm —mechanical, electrical, plumbing and structural design of buildings; original research in energy-saving technologies; designing and installing renewable energy systems; and a wide range of energy-related activities. Founded in 1989 and based in Ithaca, New York, Taitem has completed over 600 design projects, including buildings in many sectors: commercial; multifamily; industrial; healthcare; religions; and educational. The company has consulted on many LEED projects, including their headquarters in a restored nineteenth-century mansion.

Taitem’s work in the area of energy services includes performing energy audits, creating and reviewing energy models, LEED consulting and commissioning, energy planning, and carbon footprint studies. In 2005, the company earned the national R&D100 award for its work in developing TREAT energy modeling software. In 2006, Taitem Engineering led the technical effort to develop the EnergyStar for multifamily standard in conjunction with the U.S. Environmental Protection Agency and the New York State Energy Research and Development Authority.

Taitem currently employs around 35 people, including eight NYS licensed professional engineers, six LEED-accredited professionals, certified multifamily building energy auditors, certified energy managers, certified commissioning professionals, NABCEP solar installers, a master plumber, and a master electrician. 

Becoming a B-Corporation served two purposes. First, it was a way to show our community that we walk the walk, in terms of environmental and social responsibility. Second, the B-Corporation certification process provided us with a meaningful framework for self-examination, helping us to acknowledge areas for improvement and celebrate our strengths as we strive to fulfil our mission — because the Earth does matter. 


The Change We Seek ®


Taitem seeks to create change not only through the work we do, but by how we do it. Taitem Engineering is committed to providing high-quality engineering and energy consulting services that promote lower building energy use and to conduct energy research to advance sustainable energy practices and technologies. Taitem’s energy auditors and LEED accredited professionals are always thinking about how their buildings and communities are designed, constructed, maintained, and operated and how they can be improved to reduce energy consumption. Since the greenest building is the one you don’t build, Taitem’s main offices are in a “recycled” nineteenth-century downtown house that is on track to become LEED Platinum certified. Among the building’s many green features are an ultra-efficient air-conditioning system with net-zero potential, invented by Taitem’s founder and president; abundant covered bicycle parking; rooftop solar thermal and solar PV; and an EV charging station;

Taitem seeks to create positive social change by providing a flexible and stimulating workplace for their employees. This includes everything from alternative schedules and telecommuting to accommodate family and other personal needs to beautiful workspaces with lovingly preserved architectural details. Taitem also hosts a winter and summer gathering for its employees and an annual retreat to promote specific workplace goals. The popular ice-cream club strolls to a local shop to share cool, locally made treats. The company also encourages health and wellness with basketball and soccer teams and a Tae Kwon Do group. Taitem’s shared transport includes a hybrid company car and a restored classic “Free Spirit” 10-speed bicycle.
