The building built in the 1970s is located at Viale della Liberazione 16/18 in Milan.
The building is in a strategic urban location and is close to Porta Garibaldi area, which has been undergoing deep transformations in the recent years. It dialogues perfectly with the architectural present nearby, such as the new Varesine towers and the new Porta Nuova building complex. With ten floors above ground plus two existing underground floors, it has a gross floor area of about 25,000 m2.
The choice of LEED® certification is according with the property’s green environmental plan. Generali Real Estate is committed to being the real estate industry leader in environmental sustainability and energy management. Since 2009, Generali Real Estate (GRE) has adopted the Environmental Policy of the Generali Group, aimed at ensuring environmental protection and pollution prevention and contributing to sustainable development.
The renovation covers all active building systems as well as all building surfaces, the construction of two new floors, including a system of new terraces located on the highest floors. A new system of exterior elevators and public spaces (especially on the ground floor) was designed with the aim of establishing and strengthening the connection between public and private spaces. The main facades are characterized by modularity due to the presence of the existing structure; this pre-existing condition offered the designers the opportunity to optimize the facade according to exposure using high-performance glass, which differs according to orientation. At the same time, the maximum daylight is guaranteed to maximize occupant comfort. The installed plant systems are high-efficiency and combine space conditioning needs with the use of renewable resources (photovoltaic panels for electricity generation and groundwater heat pumps for heating and cooling).
Rating system: LEED® BD+C v2009 Core and Shell
Certification level: 73/110 points, LEED® Gold
Below, for each category, the percentage contribution to the total certification score. Also to the side, the score achieved against the total score that can be acquired for each category.
Preliminary assessment of the overall sustainability of the project: selection of the best LEED® certification rating and evaluation of the resulting attainable certification level.
Project team management activities through:
– Guidance on selection of materials and equipment in accordance with LEED® requirements.
– Approval of project documentation in accordance with LEED® requirements.
– Management of the project on LEED®online
Construction team management activities through:
– LEED® approval of materials and equipment
– Management for the implementation of construction plans
– Project management on LEED®online portal
Commissioning is a prerequisite for LEED®, the main purpose of which is to ensure that buildings and facilities are designed, constructed, and delivered to clients according to clear and well-defined criteria. The benefits of the process, if implemented on time, are:
– increases in occupant productivity
– containment of construction costs
– shorter plant commissioning times
energy model activity allows for the comparison of two models of the same building, baseline and proposed, the former built according to Ashrae 90.1 Appendix G and the latter in accordance with the project. The result is a snapshot of the building’s consumption. The comparison between the two models allow to calculate a percentage savings in energy cost.
