Sustainable Strategies
Langdon Woods is 58% more energy efficient than a conventional building of this size, saving the university nearly $230,000 a year. A 40% reduction in water use conserves almost 1.4 million gallons of water a year; 20% of all materials in the building are recycled with 40% coming from within 500 miles of the project site, to cut down on transportation emissions; almost 70% of the wood in the building was harvested from responsibly managed forests; low-maintenance plantings require no irrigation; and 70% of construction waste was diverted from landfills.
The building features operable windows (large windows provide daylighting and views to 90% of living spaces) and individual airflow, with thermally-powered VAV system provided by Acutherm. The Therma-Fuser DDC Interoperable Diffusers meet the set comfort requirement of each space automatically and eliminate over heating and over cooling.

Achieve benefits of Therma-Fuser VAV and complete digital input and output with the BAS. Each diffuser has the ability to supply room temperature, airflow and supply air temperature and receive signals for room temperature setpoint, minimum airflow setpoint, maximum airflow setpoint, override open, override closed, CO2 override and more. Digital signals can be either BACnet™ or LonTalk®. The BAS also monitors and controls the portions of the VAV system requiring periodic maintenance. This approach provides the Therma-Fuser VAV advantages of comfort and energy savings from individual temperature control and easy adaptability to office changes
