    Solar panels and naturalized roofs are now standard on many buildings of the Novartis Campus.

    Published on 17/05/2022

    When the passenger wagons of the Trans- Siberian Express roll leisurely along the tracks of Moscow’s Yaroslavsky station – a majestic building in the Art Nouveau style – time appears to stand still. Pulled by a huge electric locomotive and decorated in the Russian national colors white, blue and red, the Soviet-built carriages evoke a sense of times past and boundless adventure.

    Completed as early as 1916, the world’s longest railroad line not only attracts travel enthusiasts from all over the globe. The 9000-kilometer line stretching from Moscow over the Ural Mountains and across Siberia to Vladivostok also serves as a major freight route, playing a pivotal role in cross-border trade.

    During the turmoil of the 1990s, the Transsib, as the route is also known, fell into decline as the country was hit by a severe economic crisis. Yet, with China’s rise as a major economic powerhouse and following the electrification of the entire network in 2002, it experienced a stunning revival, growing into one of the world’s busiest trade routes. Increasing freight from the Far East is now being carried via the Transsib to Europe, in addition to valuable raw materials extracted in Siberia and exported all over the world. As a matter of fact, the steel beams used in the Pavillon also arrived by Transsib and ship.

    No cut corners

    The construction of the Pavillon came at a time when the coronavirus pandemic was disrupting global supply chains. The crisis was further exacerbated in March 2020 when the giant cargo vessel Ever Given ran aground in the Suez Canal, blocking one of the world’s busiest shipping arteries. The construction industry wasn’t spared these developments either, as Reto Gisiger, who heads the Pavillon project, came to experience firsthand. Although he has had to deal with difficult situations time and again in his long career, the pandemic proved a unique challenge for the veteran engineer.

    “It was an exhausting time because we had to grapple with major procurement problems,” Gisiger recalls, who had been involved in the construction of several Campus buildings before the Pavillon. “The steel shortage, in particular, gave us a hard time, not least because production capacities were scaled down significantly due to lower demand.”

    Completing the challenging project on a tight schedule under such circumstances was no easy task. Yet Gisiger kept a cool head, instructing his team to intensify the search for the urgently needed material to drive construction forward.

    Eventually, Gisiger and his team found what they were looking for in China, the world’s number one producer of steel. How­ever, the struggle was not over, as another obstacle soon arose. Container congestion and jammed ports – largely owing to the Suez Canal calamity – were causing a major slowdown in maritime logistics, preventing the steel beams from being delivered on time by sea.

    “Given the situation, we were forced to think outside the box and look for alternative transportation options,” Gisiger says. “Initially, someone on the team picked up on the idea of airlifting the beams to Switzerland. That’s when I pulled the plug.”

    Gisiger was adamant about a sustainable solution with as little impact on the environment and climate as possible. As such, his team then opted to explore the possibility of shifting to rail, which would reduce transport-related CO2 emissions by a factor of 10 compared to air freight.

    Soon after Gisiger’s team had commissioned a logistics company to organize the rail transport, the first freight trains headed to Europe with the coveted cargo – first traveling across the Mongolian steppe and the Siberian wilderness before being loaded onto ships flowing up the river Rhine in Germany.

    “It is crucial to uphold the principle of sustainability and not lose sight of the environment, even under pressure,” Gisiger explains. “Even though the CO2 reduction resulting from our switch to rail freight is relatively small compared to the total greenhouse gas emissions of Novartis, we have nonetheless managed to send a strong message to the industry while taking another stride toward carbon neutrality.”

    Green ap­proach

    Gisiger’s insistence is no coincidence. In recent years, Novartis has initiated a series of measures to achieve its climate goals and reduce carbon emissions worldwide. These include investments in solar and wind power plants, carbon sinks and saving natural resources. These measures should help Novartis achieve carbon neutrality across the value chain and both water and plastic neutrality in its operations by 2030.

    In addition to optimizing its existing facilities, the company’s sustainability strategy also includes constructing environmentally friendly buildings and complex­es. While priority was given to making all buildings as energy-efficient as possible when work on the Novartis Campus in Basel began around 20 years ago, standards have been raised steadily over time, including outside Switzerland.

    For instance, the Novartis Knowledge City in Hyderabad, completed in 2016, earned a LEED Platinum certification by the independent rating organization India Green Building Council, the highest-possible recognition for overall sustainability. Other new projects have received similarly high ratings, such as the Novartis research campus in Cambridge, Massachusetts, in addition to other buildings in China, Mexico and Colombia.

    “Being one of the most sustainable buildings of Novartis, the Pavillon aligns well with our long-standing commitment to the climate and the environment,” says Irina Stefanova, Global Head Real Estate and Facility Services at Novartis. “We are committed to setting sustainability as the norm within the industry while motivating others to follow suit. Serving as a place for dialogue and exchange, the Pavillon assumes a key role to fulfill this goal. We are motivated to demonstrate that our company cares about this important issue – after all, human and planetary health are inextricably intertwined.”

    “However,” adds Stefanova, “in doing so, our aim is not only to implement high standards, but also to show our commitment to sustainability in difficult situations and make uncomfortable decisions.”

    Among such decisions, for example, was the effort to clean up the site of the former lindane factory Ugine-Kuhlmann in Huningue, France, although neither Novartis nor any of its predecessor companies had caused the pollution. In addition, Novartis recently embarked on a project in India which aims at using new technologies to regulate water consumption through natural watersheds.

    “Achieving the sustainability goals of Novartis requires a long-term strategy, in addition to collaborating with partners in science, industry and politics in a systematic fashion,” Stefanova says. “But sometimes it also takes courage and the ability to stand up for one’s values, as well as the spirit of innovation.”

    Clear principles

    All of these qualities came into play in constructing the Pavillon. In addition to the zero-energy media façade consisting of organic photovoltaic cells and LED lights, the interior also features innovative and sustainable material solutions. For example, the walls were coated with water-based and solvent-free paints to ensure the protection of both health and the environment.

    The ventilation concept was also tailored to the requirements of sustainable architecture. For example, an automated ventilation system blows stale air outside and brings in fresh, filtered air inside, ensuring a constant exchange without consuming much energy. In good weather conditions, the continuous supply of clean air is provided by the partial opening of the building’s roof.

    Another innovative energy feature of the Pavillon is its geothermal storage system, which enables seasonal heat storage. Through earth probe drillings that reach as much as 120 meters deep into the earth, the heat absorbed by the building in summer is kept in the ground like a sort of battery to be used later on in winter. This technology, which is also employed in other buildings on the Campus, allows the handling of energy and heat in a highly ecofriendly manner.

    “By employing the most innovative techniques, we have tried to keep the carbon footprint as low as possible,” Gisiger emphasizes. “However, sustainability also implies avoiding energy-intensive systems. For example, we kept the doors small, so they don’t need an auxiliary motor and thus neither require electricity nor are expensive to maintain.”

    The many innovations and energy-related details involved did not make construction of the Pavillon any easier. “Nevertheless,” Gisiger adds, “the effort will prove to be a great advantage, especially in future, because it will allow us to keep energy consumption and therefore energy costs to a minimum. The pandemic has put some obstacles in our way. But I’m proud that we didn’t use it as an excuse to abandon our principles.”
