PUERTO DE SOMPORT 21-23 MADRID / SPAIN LEADING BY EXAMPLE Sustainable development for an environmental and human respectful work environment PUERTO DE SOMPORT 21-23 MADRID / SPAIN OVERVIEW ABOUT PUERTO DE SOMPORT 21-23 Located in the North of Madrid, in the Las Puerto de Somport 21-23 is a 20,000m2 Tablas District, Puerto de Somport 21-23 is building designed to deliver on Tishman the first stage of a three-phase development. Speyer’s ambitious Sustainable Development Once all phases are complete, the complex 2 goals. The project has been developed in will total 60,000m dedicated to office space the framework of a joint venture between and amenities. The development is adjacent Tishman Speyer and Metrovacesa, a partner to Madrid Nuevo Norte, an ambitious urban with great local expertise. Thanks to an all- regeneration scheme intended to help fulfil glass façade and higher-than-usual ceiling the City of Madrid’s contribution to the heights, the six-story construction (ground Sustainable Development Goals of the UN floor plus five) optimizes natural light. 2030 Agenda. There are two impressive lobbies with five- CONTEXT meter ceiling heights and workspaces with three-meter-plus ceiling heights. Puerto To incorporate sustainability holistically de Somport 21-23 offers a unique office throughout the project, Tishman Speyer set environment, with flexible space that can ambitious objectives based on LEED and be adapted according to tenants’ needs.

PUERTO DE SOMPORT 21-23 MADRID / SPAIN SUSTAINABLE STRATEGIES SUSTAINABLE SITE SELECTION EFFICIENT USE OF RESOURCES Puerto de Somport 21-23 promotes Puerto de Somport 21-23 focuses on the connectivity and sustainable transport. efficient use of natural resources, particularly Situated in a dense urban location, it is close water, energy and materials. to major transport hubs. Once the Madrid Minimizing water use: Water is a precious Nuevo Norte urban plan is developed, the resource in Spain, given its Mediterranean new Metro, Cercanias commuter rail and climate. Puerto de Somport 21-23 includes a priority bus line will be within a seven strategies to reduce water demand, both minutes’ walk of the project site. Other inside and outside the building. The design flexible mobility solutions, provided by the specifies low-flow fixtures and fittings, landlord, will include e-bikes, e-scooters, rainwater collection, native plant species a car-sharing service and a shuttle bus with low irrigation demand, and a highly connecting with the city center. These efficient drip-irrigation system with water- choices help reduce vehicle distance sense technology, resulting in zero water travelled, benefit public health and enhance consumption for landscape maintenance. community participation. Energy demand limitation: The building’s The development also includes design energy strategy focuses on energy demand elements to enhance walkability and promote limitation and highly efficient systems. The active modes of transport both on site and in plan includes efficient lighting with sensors the surrounding community. and controls, which also enhance occupant Additionally, Puerto de Somport 21-23 comfort and experience. provides a green, walkable city park open to Responsible material selection: The design the public. The new accessible public space uses life cycle analysis to inform responsible offers amenities for building occupants and material selection, minimizing carbon impact the community. Planted with native species, and limiting other environmental effects, it is a welcome addition to the city helping such as resource depletion and toxicity. to reduce the heat island effect, increase biodiversity and protect critical habitats.

PUERTO DE SOMPORT 21-23 MADRID / SPAIN Life Cycle Analysis: Upfront carbon IMPACT ON DESIGN AND CONSTRUCTION PROCESSES The LCA analysis covered the design and construction processes, including maintenance requirements throughout the building’s whole life cycle. Beyond carbon, other impact categories have been analysed, as shown on the graph: Overall Environmental Impact Reduction. Material selection The LCA identified that the curtain wall façade was one of the main contributors to the building’s environmental impact. As a result of our analysis, the material specification was switched to high recycled content aluminium (minimum 78% recycled). This change has made a significant difference to the environmental impact of the façade. Also, high recycled content steel (88% recycled) has been specified for structural elements. Impact reduction As a result, a significant impact reduction has been achieved, Future development view of the three phases compared to a standard practice in Spain, as shown on the graph: Overall Environmental Impact Reduction. OVERALL ENVIRONMENTAL IMPACT REDUCTION More than 10% reduction has been achieved in the global warming impact (“carbon impact”), expressed in kg CO2 eq. More than 10% reduction has been achieved in ozone formation, 10% 7% 11% 11% 12% 20% terrestrial acidification, freshwater eutrophication and fossil resource scarcity. More than 6% reduction has been achieved in ozone depletion. Such a level of impact reduction is relevant in terms of embodied carbon, and is recognized in standards such as LEED; where an impact reduction above 10% in three impact categories is awarded with 3 points in the Building Life-Cycle Impact Reduction credit. On-site tracking During the construction stage, energy, and water consumption, as well as materials, transport and waste are being tracked. When the construction works finish, the actual impact data will inform Global warming depletion Ozone formation Ozone acidification Terrestrial eutrophication Freshwater scarcity resource Fossil decision-making on future projects. Impact reduction in six environmental impact categories, compared to standard practice in Spain PUERTO DE SOMPORT 21-23 MADRID / SPAIN Life Cycle Analysis: Use stage and end-of-life carbon USE STAGE EMBODIED CARBON Replacement needs along the life of the building, and maintenance needs, have been considered in use stage environmental impacts. Operational energy has not been included in the above analysis; however, the efficient use of resources will have a direct impact on the life cycle environmental impacts of the building: Operational energy The reduction in energy consumption (by 26%) will result in a decreased contribution to global warming and other environmental factors over the building’s whole life cycle. Emissions for scopes 1 and 2 of the GHG protocol will be reduced accordingly. Water use The reduction in water use (50% in internal and 100% in external areas) will reduce environmental impact throughout the building’s whole life cycle.
