The main theme proposed for the competition was the harmonious and sustainable balance between built elements and nature, between carbon dioxide produced and absorbed, between costs and revenues, and between public and private. The central intent was to achieve a project characterized by a neutral balance of its carbon footprint, in favor of climate, economy, nature and community.
In this regard, the sustainability strategies included in the concept were also inspired by the guidelines of the LEED® v4 certification protocol.
The project included 3 buildings, as well as an underground parking lot. The first, the main one, is a conventioned studentate, while the other two are smaller single-story pavilions, both intended for neighborhood services.
The student residential portion, the main building, is raised off the ground above rich vegetation on the site and has six floors. It provides 439 beds and common spaces both distributed on the floors and grouped together.
The compactness of the circular plan of the main building is interrupted on each floor by striking extrusions that provide opportunities for the inclusion of study spaces as well as terraces for relaxation. The student residence is directly connected to the underground, private parking lots, which provide 21 parking spaces for the disabled, 15 with charging stations for electric vehicles, 17 regular parking spaces and 75 bicycle parking spaces.
The other two buildings, conceived as public services, are two small circular pavilions totaling about 1200 m2 gross, resulting in “Neighborhood Shops and Neighborhood Services,” both with green roofs and built on a single floor.
Given the intended use of the project building, one of the main objectives in developing the plant design at this stage was to maximize the modularity and flexibility of use of the spaces themselves, as well as the use of high-efficiency generation equipment. The design idea, also supported by LEED® protocol guidelines, was therefore to choose technologies aligned with the objective by adopting only electrically powered systems.This was in order to ensure energy supply from the present photovoltaic system or energy from the grid that will be delivered, as a feature of the supply, 100% from green energy.
A VRV system, a direct expansion summer and winter air conditioning system, was chosen for heating and cooling uses, offering numerous installation and management advantages. In addition, a mechanical ventilation system consisting of heat recovery units installed in the false ceilings on the floors was provided to ensure indoor environmental comfort. Regarding artificial lighting, again in compliance with the limits prescribed by LEED®, interior and exterior LED luminaires were chosen to ensure maximum efficiency, considerable service life and less maintenance.
When selecting building materials, special care was taken to ensure that materials with low carbon emissions, sourced within short distances of the construction site, with end-of-life recyclability characteristics, and with certified environmental performance were identified.
In order to control this aspect, a life cycle assessment analysis, LCA Analysis, was implemented, conducted on the estimation of key design aspects: quality and quantity of building materials used, building energy consumption and self-production of renewable energy on site, quantity and type of plant species planted in the forested area. The goal of the final carbon footprint balance was neutrality.
The proposed project also considered various measures to achieve the greatest savings in water resources with systems for reducing indoor usage, water recovery and storage, flood control, implementation of phyto-purification systems, and collection of gray water produced during use.
