The building is being designed to achieve Passive House standard of performance. In addition to reducing electric and fuel demand, the building will also create its own supply by incorporating on-site microturbine co-generation plant along with solar panels. Along with energy savings, the design also calls for water conservation via ultra low fixtures, waste management, recycling and composting. Altera Engineering was invited to participate in a completion to win the right to develop a city-owned parcel of land in Brooklyn. The project, named The ParaSol, will consist of 150 residential units. 105 apartments will be available for residents earning up to 60% of median income and 45 units will be allocated for the formerly homeless. In addition to residential units, the building will also have a 6,000 SF communal facility, retail and parking spaces as well as roof garden on the roof.

Full MEP/FP design Go EAST 10 STREET, MANHATTAN TOWNHOUSES Full gut renovation of two landmarked townhouses near historic Stuyvesant Street in Manhattan in St. Mark’s historic district. According to Landmarks Preservation Commission (LPC), 106 and 110 are two of three identical houses were built in 1867 by an Irish-American builder, James Mulry, at an estimated cost of $6,000. The three buildings were erected on the lots that Mr. Mulry leased from Hamilton Fish- the 16th Governor of New York State and the Secretary of State under Ulysses Grant. The buildings were designed in a late version of the Italianate style by D. J. Jardine Architects. The segmental-arched doorways have stone cornico-slabs supported on vertical console brackets which, in turn, are carried on paneled pilasters. They are four stories high, above a basement, and all retain their stoops. They are all three surmounted by individual bracketed cornices which are aligned at the same level. The stone basement wall is carried up to sill height at the first floor with recessed stone panels under each window. Altera Engineering carried upgrades to power, water, sewer utility connections. Our engineers worked hand-in-hand with the interior architects to thoughtfully integrate central heating and cooling systems into the buildings.
