For the BIM energy renovation of a degraded area in the South Bronx of New York – AIAS, Autodesk, Architecture2030, Majora Carter Group and Perkins Eastman – launched an international competition on invitation, with the aim to creating a new sustainable impact zero district. To achieve the required standards, we performed analysis and energy simulations from preliminary to the executive design.
Analysis and simulations
From a study of the climatic conditions of the site we have identified in the solar gain and passive ventilation in the main passive strategies to be implemented to reduce energy consumption and achieve a NetZero Building. The combined application of different specific tools to study radiation and shading allowed to define the shape and height of buildings in order to optimize the direct solar gain, reduce heat loss and maximize natural lighting in the interior spaces.
The study of natural ventilation allowed to shape the buildings and to position the openings so as to protect the facades from cold winter winds and facilitate the penetration of cooling summer winds.
Energy analysis aided design has resulted in a Neutral Carbon Building that is a building with negative CO2 emissions, the goal 2030Challange for all buildings to be designed by the year 2025. The data also show a consumption less than 80% compared to the EUI standard values for that type of building.
