The building has an efficient heat pump system with heating coil bypass for winter operation.  A gas-fired microturbine and photovoltaics contribute to the energy efficiency.  Good indoor air quality is provided by low-emission finishes and mechanically-filtered, air-conditioned, winter-humidified air.  Other sustainable design elements include a black water treatment plant, storm water reuse for irrigation and green roof.  The energy and green analyses were performed by the Energy/Green/Commissioning group of another company.  The design team included Robert Stern Architects and lsmael Leyva Architects.  The work was co-funded by the New York State Energy Research & Development Authority.

Under a FlexTech contract with the New York State Energy Research and Development Authority (NYSERDA), Vidaris professionals analyzed the energy use of the proposed Bronx Library Center, a 74,000 sq. ft., six-story structure located in Bronx, NY. Vidaris also performed daylighting analyses of the east-facing, fully-glazed façade.

Ultimately, Vidaris was engaged by the NYPL directly to provide Design and Construction Phase commissioning to address LEED Fundamental and Additional Commissioning for the project.

Bridgeport’s program is fashioned to provide healthier environment for students and staff, to enhance the ambient features that promote learning, and at the same time, to reduce operating costs. The latter refers to energy use maintenance and repairs. Standardization of materials, systems and techniques is expected to reduce expenditures for procuring and stocking replacement parts, to increase familiarity of the maintenance personnel with the building systems they care for, and also to speed up the response to urgent needs for the remedial action.

 

The MiMa Hotel and Residential tower was designed by Architectonica (design architect) and Ismael Leyva Architects (project architect).  It includes a 24-story hotel and 57-story residential tower, retail, a residential gym, meeting spaces, lounges (indoor and outdoor), a theater, and underground parking.  Stormwater collected from the roof areas is used for irrigation and cooling tower.  Low flow fixtures throughout the residential, hotel and commercial spaces further reduce the potable water use.  Various energy efficiency strategies are incorporated including lighting density reductions through fluorescent and LED lamps, occupancy sensors in hotel rooms and administrative spaces, highly efficient water loop heat pump system with hot water winter bypass, and efficient transportation systems.  As a result, the project shows over 21% energy cost savings over the LEED baseline.

Vidaris provided consulting services on energy efficiency and LEED/green, as well as on tax deductions under Section 179d of the Federal tax code.

The New York State Energy Research Development Authority (NYSERDA) cofunded Vidaris' consulting.

Solaire was the first high-rise residential building to simultaneously use several advanced sustainable initiatives, such as outdoor air delivery to apartments (with winter humidification), black water treatment plant, storm water capture, green roofs, etc.  The chiller/heater system ensures an energy efficient operation.  Vidaris professionals performed energy and green/LEED analyses and participated in the commissioning of MEP systems.  The design team included Pelli Clarke Pelli Architects for design and SLCE for AOR.  The work was co-funded by the New York State Energy Research & Development Authority.

This 35-story tower has 234 "green" apartments that feature low-emission finishes and mechanically-filtered, air-conditioned, winter-humidified air.  Other sustainable design elements include a black water treatment plant, storm water reuse for irrigation and green roof.  A gas-fired microturbine and photovoltaics contribute to the energy efficiency of the building.  Vidaris professionals performed energy and green/LEED analyses. Vidaris professionals also performed the commissioning of MEP systems.  The work was co-funded by the New York State Energy Research & Development Authority.

The Visionaire is a high-rise 35-story residential tower in lower Manhattan with a 10-story base. It holds 250 condominiums, a children’s play area, spa, fitness center, pool, two roof gardens, below-grade parking, a convenience store, and an office for a Conservancy agency. The facade is comprised of a terra-cotta rainscreen curtain wall with low-e insulated glass and almost 4,500 sq. ft. of PV panels. Vidaris was involved with the consulting of the design as well as both mockup and site inspections. Sustainable features include photovoltaic panels at main roof bulkhead, a green roof, and low-e coated glass.

Its corner mansard roof a jaunty presence on Madison Avenue’s streetscape, The Mark at 77th Street first opened its doors in 1927. A suave Italian Renaissance design from the celebrated firm of Schwartz & Gross, the hotel was given a comprehensive interior renovation by the French designer Jacques Granges in 2009 and currently incorporates 10 cooperative residences in addition to 150 hotel rooms. Vidaris consulted on the replacement of all windows and the removal and infill of all PTAC units, matching the exterior brick of the landmarked building and completely cleaned the façades.

The towers, united by a common base, have many notable features including tempered outside air mechanically-delivered to each room, winter humidification, a black water treatment system and a photovoltaic array. Vidaris assisted the project team in enhancing the efficiency of these features, and of others as well, by taking a comprehensive approach to energy savings via design.  This approach also included reduced thermal bridging in opaque walls, green roof with higher levels of insulation, and spectrally-selective low-e glass.  The low-density lighting fixtures feature occupancy sensors for corridors, stairs and garage, and a daylight dimming system in the lobby.  The HVAC system utilizes water loop heat pumps with condensing boilers and cogeneration and heat is recovered from the cogen system. 

In addition to the potable water savings due to the black water system, the building also recovers storm water management for irrigation. Indoor air quality is enhanced not only by the outside air system, but also through selection of low-VOC materials. Maintenance procedures minimize tracking of pollutants into the building. Cleaning is performed with low-impact detergents.  Many other sustainable features (green roofs, locally-sourced materials, high recycled content) contribute to the environmental footprint of these towers.

The team consisted of design architect Ehrenkrantz Eckstut and Kuhn (currently joined with Perkins Eastman), project architect Costa Kondylis (now GKA) and Kondylis Design for the interiors design. NYSERDA has cofunded Vidaris' consulting.
