Passive Cooling: The Latest Architecture and News

Revisiting Skyscraper Design: The Benefits of Responsive Facades and Passive Designs

Our contemporary society has been witnessing a surge in skyscraper construction in urban centers worldwide for various reasons—including engineering advancements, increased urban density, space constraints, and, arguably, a competitive drive for building the tallest structures. The allure of all-glass facades and the pursuit of curtain walls with larger panes of continuous glass have often come at the cost of functionality.

In these towers, operable windows are sacrificed for aesthetics and expansive views, with a central core layout that maximizes 360-degree views while creating architectural "solar heat-gain monsters." Without natural or cross ventilation, these glass skyscrapers trap significant heat from solar radiation within habitable spaces, relying almost exclusively on mechanical HVAC systems to cool these spaces. This raises the question: is passive ventilation strategy becoming obsolete in high-rise design, or can operable systems be integrated effectively into our high-tech towers?

Zaha Hadid Architects Reveals Design for New Scientific Research Centre in Tashkent, Uzbekistan

Zaha Hadid Architects (ZHA) have been announced as the architects for the Alisher Navoi International Scientific Research Centre, an expansive cultural and educational facility taking shape in New Tashkent, Uzbekistan. The center is set to incorporate the Navoi State Museum of Literature, along with a 400-seat auditorium and an International Research Center and residential school dedicated to training 200 students in the Uzbek language, literature, and music.

Reimagining The Mashrabiya: Functionality and Symbolism in Contemporary Architecture

For centuries, arid environments have solved the problem of light, privacy, and heat through a statement architectural feature of Islamic and Arab architecture, the mashrabiya. Crafted from geometric patterns traditionally made from short lengths of turned wood, the mashrabiya features lattice-like patterns that form large areas. Traditionally, it was used to catch wind and offer passive cooling in the dry Middle Eastern desert heat. Frequently used on the side street of a built structure, water jars, and basins were placed inside it to activate evaporative cooling. The cool air from the street would pass through the wooden screen, providing air movement for the occupants.

Similar to the Indian jali, the vernacular language also offers a playful experience with daylight while still maintaining a certain degree of privacy. Traced back to Ottoman origins, the perforated screens protected occupants’ from the sun while simultaneously letting daylight through in calculated doses. Although the mashrabiya was a statement in arab and Islamic architecture languages, it wasn’t until 1987 that the archetypal element began appearing with a revised contemporary application.

Decarbonization and Energy Efficiency in Latin America: How to Progress Towards a More Sustainable Architecture?

In the context of global initiatives to promote energy efficiency and the decarbonization of buildings, Latin America is at the center of the debate. The International Seminar on Sustainable and NetZero Buildings 2023, held in Bogotá and organized by CCCS, IEA, UNIANDES, CAF, and CEELA, aimed primarily to create a space for the exchange of experiences, such as Oliver Schütte's No Footprint House, while simultaneously conducting a review of government policies and the implementation of norms and standards in the region.

Among panels and conferences featuring Clara Camarasa, Nicola Borregaard, Laura Chapa, Paola Valencia, Iván Osuna, Juan Carlos Vega, Angélica Ospina, and Diego Velandia, five main learnings emerged as lessons: from creating more relevance and energy calculations to the development of the timber industry - and certifications.

Journey to Energy Efficiency: 10 Spanish Homes Applying Bioclimatic Strategies and Designs

How is it possible to reduce the energy consumption of our homes? What design, material, and/or technological strategies can be developed to achieve interior comfort while also addressing the climate crisis? While achieving energy efficiency depends, among other factors, on the state of the homes, there are various strategies related to the implementation of renewable energies, air conditioning technologies, and more that can be applied, taking into account government policies, laws, regulations, and standards specific to each region.

Designing for Water Scarcity: How Architects are Adapting to Arid Environments

An arid environment refers to specific regions characterized by a severe lack of available water and extremely dry weather conditions. More specifically, arid regions by definition, receive less than 25 centimeters of rain per year. In the immense vastness of arid environments, where extreme climates present significant challenges, the role of water in architecture takes on a new dimension.

For centuries, architects and designers dealing with harsh desert landscapes and the vital necessity of water have invented techniques, technologies, and new structures. Moreover, many creative approaches have been created to harness, collect, and cool water in arid environments.

What is a Traditional Windcatcher?

Before fossil-fuel powered air-conditioning became widely available, people living in harsh climates had nothing but natural means to ventilate their spaces and control the interior temperature. To do so, they took into account several external factors such as their location, orientation with respect to the sun and wind, their area's climate conditions, and local materials. In this article, we explore how ancient civilizations in Western Asia and North Africa have used windcatchers to adapt to the region's harsh climate and provide passive cooling solutions that are still being used in contemporary architecture, proving that local approaches to climate adaptability are fundamental to the development of today's built environment.

Back to Basics: Natural Ventilation and its Use in Different Contexts

Automation is everywhere around us - our homes, furniture, offices, cars, and even our clothing; we have become so accustomed to being surrounded by automated systems that we have forgotten what life was like without them. And while automation has noticeably improved the quality of interior spaces with solutions like purified air and temperature control, nothing compares to the natural cool breeze of mother nature.

But just like everything else in architecture, there is no one size fits all; what works in Tanzania cannot work in Switzerland or Colombia. This is due to several reasons, such as the difference in wind direction, average temperature, spatial needs, and environmental restrictions (or lack thereof). In this article, we take a look at natural ventilation in all its forms, and how architects have employed this passive solution in different contexts.

What Materials Keep Buildings Cool?

Air-conditioning isn’t just expensive; it’s also terrible for the environment. Accounting for 10% of global energy consumption today, space cooling in 2016 alone was responsible for 1045 metric tons of CO2 emissions. This number is only expected to increase, with the International Energy Agency estimating that cooling will reach 37% of the world’s total energy demand by 2050.
