Plants drape down the walls, and sunlight floods the interior. This isn’t just any building; it’s a hospital set to rise in Lombardy, Italy. Designed by Zaha Hadid Architects, this structure aims to address not just health but also environmental concerns.
The Climate Crisis and Architecture
On December 12, 2025, Zaha Hadid’s firm revealed plans for the new Malpensa Hospital. Chosen from many designs, it will serve over a million residents in Milan and Varese. Known for striking designs like the Dongdaemun Design Plaza, Zaha Hadid Architects plans to connect nature and structure. This isn’t merely about aesthetics; it’s about making a statement against climate change.
The hospital will utilize modular construction. This means parts are made elsewhere and then assembled on-site, which saves time and resources. An insulated building envelope reduces energy needs significantly. The hospital aims to produce enough solar power for a quarter of its electricity needs, cutting cooling energy by 30%.
Globally, there’s a surge in green architecture. Recent research from the University of Toronto found that construction activities in 1,033 cities produce around two million tons of CO2 each year—about two tons per person. The United Nations Environment Programme (UNEP) reported that buildings account for 37% of global greenhouse gas emissions. To keep the planet below a 2℃ temperature rise, we need to slash these emissions by 90% within 20 to 40 years, focusing on how we build and operate our structures.
Innovations in Construction Materials
The journey to reduce emissions begins even before construction. Cement production is a major culprit, contributing to about 8% of global CO2 emissions. Alternatives like Low-Carbon Cement (LC3) and geopolymer concrete are emerging, promising to cut emissions significantly. Jeong Jin-woo from the Korea Institute of Civil Engineering states that LC3 can reduce emissions by 30-40%, while geopolymer concrete offers an impressive 60-80% reduction.
In 2024, researchers developed a new type of concrete called CEC, which captures CO2 during its curing process. This innovation allows construction materials to not just minimize emissions but also actively reduce existing CO2 levels. At the same time, wood is making a comeback as a sustainable material. Cross-Laminated Timber (CLT) is lightweight yet strong, making it ideal for modern building techniques.
Energy Efficiency in Buildings
Once built, it’s vital to ensure buildings remain energy efficient. Seo Dong-hyun, a professor at Chungbuk National University, highlights that energy-saving methods focus on enhancing insulation and tapping into natural energy. Improving insulation reduces heating and cooling needs, while passive designs like high ceilings allow sunlight to illuminate spaces.
Electrification is another trend, moving buildings away from fossil fuels entirely. Heat pumps are key here, efficiently heating and cooling spaces. Connecting buildings to renewable energy sources can further cut emissions.
Experts agree achieving net-zero emissions in the construction sector is theoretically possible but presents challenges. Existing buildings, often not designed with energy efficiency in mind, create significant hurdles. Green remodeling initiatives aim to rectify this, and economic obstacles remain. Utilizing cost-effective, low-carbon materials is essential, and providing financial incentives could encourage more eco-friendly building practices.
Conclusion
Building designs like the Malpensa Hospital point the way forward. Experts believe that with the right technology and approaches in place, we can make significant strides toward a greener future. Achieving net-zero emissions is not just a lofty goal—it’s essential for the health of our planet and new architectural visions.
