LEED 2009 BD+C (Core & Shell) Platinum
The building originally known as 'Residence Porta Nuova' was completed in 1973 to the design of Marco Zanuso and Pietro Crescini. It is representative of a series of built projects realised in the Porta Nuova area and remains an important indicator of the architectural activity of that period, typical of a particular climate in Milan.
The 'horizontal' pattern of the building is one of its main features and our scheme has used this distinctive characteristic as a strong point in terms of the relationship with the street, acting as a contrast to the the verticality of the newer constructions.
A thorough philological analysis of Zanuso's building, together with a new design direction concentrated on attention to detail, has endowed the spaces at Gioiaotto with a flexibility and internal brightness that is in keeping with contemporary architecture, supported by the prestige of a unique building that is very much part of Milan's history.
The entrance hall immediately presents a contrast between rough surfaces that refract and others that reflect the natural daylight and artificial lighting at night.
Inside the floors a large glazed section follows the horizontal structural grid and is divided vertically into three. The upper part, opaque and inclined, directs natural light onto the ceiling. The middle part, completely transparent and openable places the working environment in communication with the outside while the lower part alternates between filing cabinets adjacent to workstations and concealed fan-coil heaters. The rhythm of the glazing inside is highlighted by fins in extra-clear glass that increase flexibility by enabling the installation of mobile partitions as desired, while on the outside via the alternation of fins in extra-clear glass and coloured glass in light-grey. In front of the columns are boxes in micro-perforated bent-pressed steel. In the hotel part the rhythm of the existing windows is highlighted via the alternation of blades in transparent glass placed in discontinuity with the fins and timber boxes.
As with the office area, the ground floor has a rhythm of transparent modules made from glass to guarantee maximum connection and exposing the accesses to the building at ground level, placed in discontinuity with the opaque structural parts covered by screen-printed windows on two levels to increase the three-dimensional effect of the façade.

The refurbishment of the 1970’ existing building, originally designed by Marco Zanuso e Pietro Crescini, aimed at achieving high energy and sustainability performances while providing high-spec offices and hotel. The intervention is part of the regeneration of the Porta Nuova district, in Milan.
Thanks to a combination of energy efficiency and green building features, the design and construction team’s strong commitment to sustainability, the development was awarded the prestigious LEED Platinum certification (88 points) from the U.S. Green Building Council.
The sustainable approach for the building energy retrofitting included the following:
32% reduction of the overall building energy cost;
48% of the indoor potable water demand;
56% of the water usage for outdoor uses (irrigation);
Sub-metering to closely control energy and water demand in the various indoor areas;
85% of the construction waste was recycled;
Building materials specified with high recycled content;
Formaldehyde free indoor finishes;
70% of timber-based materials FSC-certified;
Thermally broken windows with high-performance double-glazing units (U-value= 1.32 W/m2K);
Highly-energy efficient HVAC systems with no CFC-based refrigerants;
Reversible heat-pumps (heating & cooling) with self-regulated system to optimise energy cycle throughout the year;
BMS and building automation to closely control local devices and manage heating and water systems;
A 10kWp photovoltaic array fitted on the roof.
The overall cost of the retrofitting was 1130 euros/sqm.
