SCOPE . full MEP design and construction administration services Go Go A 22,000 square foot ground up high rise commercial office building in New York city. This boutique building contains 8 full floor offices above a 3-level parking garage. 621 West 55th Street is being designed to meet US Passive House Institute standards for energy efficiency. Passive House standard emphasizes air-tight, continuously insulated building envelope without thermal bridges, high performance windows and balanced heat and moisture recovery ventilation. Passive House buildings are expected to consume 75-90% less energy than traditional buildings. The biggest challenge for MEP systems was to minimize the impact of the high rise MEP system requirements on an relatively small floor plate (2,400 SF). A fire protection tank, standpipe, generator, ventilation systems all eat up valuable floor area and the project becomes less financially viable. The Altera Engineering team worked closely with the architect to optimize MEP systems to achieve the largest possible usable area. The building is cooled and heated with a variable-refrigerant system. Packaged rooftop energy recovery ventilator filtered and conditioned fresh air directly into each office in a continuous ventilation cycle. MEP systems include a 150-kW emergency generator with a diesel tank, an underground suction tank for fire protection, and reversible air-flow parking garage exhaust system with post-fire smoke purge functionality.

In 2017 the Department of Housing Preservation (HPD’s) identified 87 vacant lots to be included into its New Infill Homeownership Opportunity Program (NIHOP). NIHOP seeks to promote mixed-income communities with affordable homeownership opportunities for moderate- and middle-income households earning up to 80-90 and up to 130 percent of Area Median Income (AMI). The program provides land and construction financing to qualified developers with the goal to build affordable condominiums for working families in low income neighborhoods. The agency’s goal is to spur neighborhood revitalization directly through infill of vacant lots and indirectly through creation of opportunities to own property in the areas where homeownership is beyond the reach of many residents. Altera Engineering is proud to be involved with a number of NIHOP projects. One of them- Rochester Suydam- consists of 3 clusters of 7 new buildings along Herkimer Street, Rochester, and Ralph Avenues in the Bedford Stuyvesant neighborhood of Brooklyn. The 7 buildings contain a combined total of 66 one- and two-bedroom apartments with a combined project size of 66,336 square feet. All the buildings within the NIHOP program are designed to a higher energy performance criterion than required by 2016 New York city Energy Conservation Code. Although the 66 units vary in layouts and sizes, all are provided with state-of-the-art central air HVAC and smart thermostats, thermally broken windows, Energy Star appliances, WaterSense plumbing fixtures, and LED lights with occupancy and daytime dimming controls. One of the biggest challenges for the design team was the budget. Because of HPD funding limits, each apartment had to be built for less than $ 70,000. Altera Engineering worked hand-in-hand with architect, sustainability consultant, developer, and vendors to carefully size and select MEP equipment while meeting energy efficiency and comfort goals of the project. Cooling and heating systems include residential single-zone ducted mini split systems, gas-fired condensing domestic water heaters. Fresh air is introduced into each apartment via energy recovery ventilators. Home / Multifamily ROCHESTER SUYDAM NIHOP ARCHITECT . PROJECT SIZE . PROJECT COST . SCOPE .

31 Lispenard Street is a modern condominium development in Tribeca, a trendy and historic area of Lower Manhattan known for its cast-iron buildings and upscale vibe. Development Overview: This is a new condo project by Urban Standard Development, a company specializing in ground-up construction and renovations. The building replaces an older one-story mixed-use structure from 1947 that had five units, two of which were residential. Building Specifications: Height and Units: A seven-story building standing 89 feet tall, with 5 residential units. Size: Total area of 12,603 square feet, including 10,362 square feet of residential space and 1,031 square feet of ground-floor retail. Design: Features a sleek, contemporary look with a conventional storefront and arched windows on the residential floors, blending modern gloss with Tribeca’s brick aesthetic. The architect is GF55 Partners, known for similar urban projects. Status: Full demolition permits were filed by 2018 for the prior structure, and by 2019, plans were presented to the NYC Landmarks Preservation Commission (LPC) for approval, given Tribeca’s historic district status. Renderings of both interior and exterior were unveiled around then. As of March 2025, it’s likely completed or nearing completion, though I don’t have real-time confirmation. No offering plan was filed by 2019, but Tribeca’s median condo price ($4.5 million) suggests these units would be high-end. Location Details: Address: Corner of Lispenard Street and Church Street, in the heart of Tribeca. Neighborhood: Tribeca (Triangle Below Canal Street) is famous for its loft-style homes, cobblestone streets, and proximity to SoHo. It’s a hub for art, dining, and luxury living. Nearby: Steps from Canal Street, the Canal Street Market, and transit options like the Canal Street subway station (A, C, E, 1 trains). Cultural spots like the Tribeca Film Institute are also close. Historical Note: Lispenard Street is named after Anthony Lispenard, who owned the land in the 18th century. The area evolved from meadows to a 19th-century trade hub, and now a chic residential zone. Additional Context The original building at this address was a modest 17-foot-tall structure owned by Peter Matera of Urban Standard Capital before its demolition. The new development reflects Tribeca’s ongoing transformation, balancing preservation (via LPC oversight) with modern luxury. Home / Multifamily 31 LISPENARD ARCHITECT . PROJECT SIZE . PROJECT COST .

Design, approvals and construction administration of mechanical, plumbing, sprinkler, electrical and fire alarm systems. The building is being designed to meet Passive House performance standards, featuring a highly efficient building envelope and low energy heating and cooling systems. Altera presented several options for heating, cooling, and domestic hot water generation. After careful consideration, the owners elected to use a variable refrigerant volume (VRV) system for the building's heating and cooling needs. However, Altera engineers faced challenges due to the mandated phase out of R410A refrigerant, which introduced regulatory uncertainty surrounding the use of VRV systems. The newer generations of VRF refrigerants, classified as A2L, are more flammable, and their use has not yet been fully codified in local building regulations. To address this challenge, the team referenced the International Building Code and leveraged the European experience with A2L refrigerants, incorporating design provisions that allow for future adaptation of these refrigerants in New York City. The resulting design incorporates a 3 pipe heat recovery variable refrigerant volume system distributed up and down the building via rated and vented shafts. For the domestic water heating, a CO2 driven heat pump system was selected. To overcome the low rate of heat recovery of the CO2 heat pump system, 7,000 gallons of hot water storage were provided.
