A sustainable approach is the backbone of the design approach of the 6th Palazzo ENI, one of Italy’s largest energy companies and one focused in integrated energy, outside of Milan. ENI is a private company forged on the discovery, refinement, transport, transformation of natural gas and petrol into power, hence the thorough demands on sustainable applications of the competition brief.
Below we map out our strategy, as designed together with our consultants (find links below).
The sustainability strategy for the design of building has been divided in the following five subjects:
1. Challenging conventions: The goal was to reduce the energy demand by 65%; satisfy the demand of energy with renewable off site energy; and to influence user behaviours by raising the awareness of energy use through technology and stimulating an active experience for users of the building.
2. Aiming high: The goal was to achieve carbon neutrality, while at the same time considering the economical aspect in two scenarios:
Scenario1: LEED Gold and Energy Efficient Best Practice.
Scenario 2: LEED Platinum and Zero Carbon Energy Positive +Carbon Neutrality.
3. Think holistically: We are considering real data, therefore analysing Co2 emissions derived from existing buildings, public areas, transport system, consumer services, material embodied energy and food supply.
4. Focus on the performances: With data from energy and transport, parameters for planning and decision making and addressing specific social, economic, environmental and resources have been applied, hence closing the cycle of CO2 on a local scale.
5. Monitoring: To achieve long-term sustainability for the environment digital Medias are applied to monitor the key performance such as energy consumption, emissions of carbon dioxide and consumption of water in order to evaluate their progress towards its objectives in the design phase and planning. The project hereby shows people the relation between their daily choices and CO2 consumption.
Carbon strategy and assessment
In a typical office, 65% of the total emissions are from the people who are using the building. In order to obtain significant results, protocols provided by Carbon Disclosure Project (CDP) and the Green House Protocol (GTP) were applied:
• Scope 1: Emissions controlled within and generated from the building
• Scope 2: Electricity derived from the network
• Scope 3: Emissions resulting from the occupants of the building
This strategy aims to reduce the emissions generated by operations of the building using passive strategies, an efficient MEP system, an environmentally conscious skin and influencing the behavior of the office users. An awareness program is set to change food habits, lead to reduce the use of potable water by 40%. The choice of building materials has a strong influence on the environmental impact on the building during the construction phase. Materials with a low content of “embodied energy” can reduce emissions by 13% compared to a building that uses traditional materials (BAU - Building As Usual).
This strategy incorporates points made in scenario 1 as well as improvement of the water system management and an increase in the use of energy from renewable sources. We also proposed to improve the central heating system, and allow the building to be a prototype for an upcoming smart grid. Scenario 2 is conceived as a dynamic strategy that evolves along the life span of the building and it aims at carbon neutrality as final outcome.
Scenario 1 – LEED GOLD
To achieve this goal, several strategies have been studied:
1. Sustainability of the site
2. Development site
3. Water management
4. Energy and emissions
5. Materials and resources
6. Indoor environmental quality
Scenario 2 – LEED PLATINUM
This scenario proposes a strategy to achieve progressive energy neutrality, balancing not only the energy used, but also improving the environmental conditions. To obtain this result the strategies to achieve LEED Gold are implemented, along with the following:
1. Water management
2. Energy and atmosphere
4. Materials and resources
5. Innovation and design process
