29 BROADWAY, NEW YORK, NY
LEED GOLD CERTIFIED / 2007 ACEC-NY DIAMOND ENGINEERING EXCELLENCE AWARD

As part of its commitment to environmental responsibility, Dagher Engineering designed its office space to achieve LEED™ Gold certification. The design includes the build-out of 10,000 square-feet of office space, and incorporates numerous sustainable and earth-friendly elements. Dagher Engineering was the first engineering firm in New York City to obtain LEED certification for its offices.

Acting both as the designer for the MEP systems and the LEED™ consultant for the project, the firm focused on integrating energy efficient systems, incorporating natural lighting, using sustainable finishes and materials, and promoting excellent indoor air quality. Innovative design solutions included:

Radiant cooling panels: Adapted to a building with operable windows, the ceiling panels represent the first use of this technology in the U.S.

Variable air volume discharge rates: A single zone system takes advantage of varying fan speeds without the added expense of installation—resulting in space-wide comfort and a substantial reduction in energy consumption.

Demand-controlled ventilation rates: Maximizes occupant comfort and operating costs by introducing variable rates of ventilated air based on occupant density.

UV lights: Incorporated into the design of the air handling units irradiating wet surfaces to eliminate the probability of spore entrainment.

Water conservation techniques: Dual-flush toilets and waterless urinals.
