|3. LEED standards in Italy|
|Currently in Italy the protocol is applied according to two schemes:|
|1. LEED Italy New Buildings and Renovations|
|The result of a reworking modeled on the Italian regulatory system and adapted to the needs of the national building market. Globally recognized, it is part of the LEED rating systems.|
|2. GBC Home Residential Buildings|
|Reference for the Italian residential market, GBC HOME is the standard adopted in our country. Starting from the American model applied to residential construction, the system in Italy is voluntary and aims to ensure the socio-economic well-being of future users.|
|The Italian territory in recent years has registered an increasing number of LEED certified projects, more than 400 buildings with a total area of 5.3 million square meters.|
|The most active areas in this regard are represented by Lombardy, Trentino Alto Adige and Lazio, regions where Public Administrations have been most committed to sustainability.|
|If the design were more attentive to respect for the environment and the intelligent use of resources, in addition to minimizing the impact on the territory, it would provide an added value to the building which would thus be placed in a high-end building market.|
|This would result in high energy savings, waste reduction during construction, economic savings and the psycho-physical well-being of future users.|
|Below we analyze two Italian case studies that rank among the first certified buildings on the national territory.|
|LEED Italy certified examples: Tortona 33, Milan|
|Rating System: LEED NC
Rating Date: 2009
Score or Rating Result: Platinum
|Placing itself among the 16 Italian buildings that obtained the Platinum level in the certification of the American Green Building Council, the building in Via Tortona 33 in Milan earned 87 points out of 110 in the rating system. This is a renovation that is attentive to environmental sustainability and aimed at achieving high levels of energy efficiency, today considered a virtuous example of conservation and redevelopment of the urban building heritage.
From the point of view of the design choices, the structural components were maintained, opting for a new makeover of the interior spaces and the technological components.
Particular attention has been given to the study of the interiors conceived with an eye to the needs of the individual future user; the design was carried out with particular attention to the social aspect which aims at the well-being of the employees who will occupy the spaces of the new building. In fact, the latter were called into question during the first phases of the project and involved in a series of workshops aimed at identifying the fundamental elements of the working space. Thanks to the decision to proceed in a "participatory" way, the need was found to ensure privacy to the internal spaces and at the same time socialization and collaboration between colleagues. In order to ensure these needs, the choice envisaged a continuous environment that intersperses semi-closable spaces, chat boxes and buzz rooms capable of integrating individual and concentration activities with moments of discussion and collectivity.
Furthermore, a careful study of the color to be allocated to the interior was carried out since, by uniting one from the other without material divisions, it allowed a “spontaneous” distinction.
This is how the reception hall is tinged with orange, a symbol of energy and socialization, while the relaxation corners are dressed in white or green to instill tranquility and peace during the breaks of the working day.

|The retrofit project has set itself the goal of lightness and overall transparency, and for this reason, large transparent surfaces and a small footprint of the metal support components were chosen.|
|The facade of the building is made up of modules of various sizes, all in tempered and laminated glass, anchored to the stainless steel structure consisting of a system of tie rods and fins.|
|Technological details on the facade: glass panels and stainless steel anchors|
|An element of fundamental importance is the entrance atrium of the building, with its irregular shape and completely glazed, it appears a casual element approached to the complex.|
|The construction phase was conducted with respect for the environment and with a view to minimizing energy consumption: most of the materials used are recycled and come from local companies and the construction waste has been destined for future recycling.|
|Furthermore, some measures adopted guarantee excellent energy performance at low cost; the recovery of groundwater, the radiant ceiling panels that guarantee internal thermal comfort, the green roof that keeps the building temperature optimal.|
