Throughout history, doors—and later automatic doors—have served a far greater purpose than merely marking an entrance or exit. They define thresholds, guide the flow of movement, and subtly shape the way people interact within a space. We can trace their evolution back to the 1st century, when Heron of Alexandria devised a steam-powered door—an early example of technology merging with architecture. Since then, contactless automatic door systems have incorporated technological advancements that enhance operation and redefine their role within buildings. Today, they are integrated across a range of building types and scales, acting as transitional elements that enhance comfort, energy efficiency, and the overall quality of indoor spaces.

Understanding the temperature gradient in a building is essential in cold or temperate climates, where airtight enclosures and continuous insulation are used to prevent heat loss. However, this approach is not suitable for tropical areas like Central America, where the climate is marked by a consistent alternation between wet and dry seasons rather than four distinct ones. Factors such as proximity to the sea, elevation, and local topography influence microclimates across short distances, but high humidity remains a common challenge. Sealed, airtight walls with no ventilation can quickly become breeding grounds for mold, making the thermal strategies of temperate climates problematic. In response, local designers have developed alternative approaches that embrace, rather than resist, the outdoor environment, allowing airflow and evaporation to manage interior comfort.
Polycarbonate, commonly used in roofing and industrial cladding, has gone beyond its initial applications to become a material widely used across various architectural typologies. Its combination of strength, lightness, easy installation, and ability to allow natural light to pass through has made it an attractive option for residential,educational, and even cultural architecture projects. In homes, polycarbonate not only helps create bright and comfortable environments but also allows for creative use of translucency to generate private spaces without sacrificing visual connection to the outdoors.
Vernacular construction technologies are based on centuries of practical wisdom, refined through countless trials and errors. This process eliminates all irrelevant aspects, creating highly efficient and simple systems that are intrinsically adapted to the local climate and resources. These methods demonstrate how to conserve heat with minimal energy, offering valuable insights for modern buildings, promoting energy efficiency, and environmental harmony. In this article, we have already covered traditional passive cooling techniques, such as Persian wind towers and Arab mashrabiya. Now, we turn our focus to strategies applicable to cold climates, exploring effective solutions for heat retention and space heating.
Over-providing traditionally implies offering more than is necessary, often carrying a negative connotation due to the potential for excess and waste. However, could there be scenarios within the built environment where over-providing proves advantageous? The question critically examines how overprovisioning might enhance a building's flexibility and adaptability to diverse and evolving conditions.
The underlying assumption of accurately providing what is needed for a building is that stakeholders—including owners, architects, and designers—can accurately predict and cater to a structure's current and future needs. This assumption, however, is challenging to realize, as societal, economic, and cultural shifts frequently occur in unpredictable ways. In this context, over-providing emerges as a counterintuitive yet potentially beneficial strategy. As buildings and structures inevitably transform, those designed with inherent adaptability reduce the need for costly renovations or complete rebuilds.

As temperatures rise globally, the impacts of urban heat islands—once considered an invisible threat—are becoming increasingly pronounced and ever more dangerous. Despite this mounting threat, however, the public realm which constitutes about 30% of cities offers immense potential to provide respite from scorching heat and introduce new opportunities to improve urban resilience efforts. As global temperatures rise, cities in regions like the United Arab Emirates and India are facing unprecedented challenges in maintaining livable urban spaces.
ICON, the office that pioneered large-scale 3D printing, has announced a new residential development of 3D-printed homes to take shape at Wimberley Springs, in Texas, United States. The complex, comprising 8 single-family homes, features designs from ICON’s CODEX Digital Architecture Catalog. The houses, currently under construction and available for sale, leverage ICON’s robotic technologies to create an energy-efficient, low-carbon construction process.
Thermal mass is the ability of a material to absorb, store, and release heat. Used to moderate building temperatures by reducing fluctuations, the concept is crucial in improving energy efficiency. Materials with relatively high thermal mass, such as stone, concrete, rammed earth, and brick, can absorb significant heat during the day and release it slowly when temperatures drop at night, reducing the need for heating and cooling systems. Properties like heat capacity, thermal conductivity, and density are all considered when assessing the thermal mass property of a material.
A Trombe wall is a passive solar building feature that enhances thermal efficiency. Positioned on the sun-facing side of a structure, it consists of a wall made from materials like brick, stone, or concrete, and a glass panel or polycarbonate sheet placed a few centimeters in front of it. Solar radiation penetrates the glass during daylight hours and heats the masonry wall. This wall then slowly releases the stored heat into the building during the cooler nighttime hours, maintaining a more consistent indoor temperature without the need for active heating systems.
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.
As the architecture industry shifts its focus towards greater sustainability and energy efficiency, many modern projects in the world’s hottest (and getting hotter) environments are unearthing more traditional ways to control temperature, light, and ventilation by learning from the past to save us from the future.
We are on the brink of concluding the hottest year in the past 125,000 years. Recently, elevated temperatures have adversely impacted the daily routines of a significant portion of the population, particularly those who spend most of their day outdoors without access to air-conditioned environments. Excessive heat stems from various sources, both natural and human-induced. Given the grim outlook on this matter, it becomes imperative to explore structural measures to address and mitigate the potential deterioration of public health caused by escalating temperatures.
Some of the most picturesque projects are those built in the mountains; the rustic cabin wrapped with a floor-to-ceiling glass panel that overlooks the snow-covered trees. Visually, the architecture exudes an enchanting feeling, but is it truly a habitable space? When houses are built on an elevation of 3,000 meters, installing a fire element alone is not efficient or sustainable. Spaces on such altitudes or particular geographic locations require to be treated thoroughly, beginning with the architecture itself. Whether it's through hydronic in-floor heating systems or wall-mounted chimneys, this interior focus explores how even the most extreme winter conditions did not get in the way of ensuring optimum thermal comfort.
The world's recent shift towards prioritizing wellness has influenced people to seek healthier lifestyles by understanding the body and the mind collectively. External factors such as the geographic location, the environment, the community, financial status, and the relationships with friends and family have all shown to have considerable impacts on an individual's health. However, it became evident that ensuring physical and mental health was not limited to having access to medical facilities and professional treatments, but was also determined by several factors related to the quality of the built environment.
Architects have a choice to design better and consequently, help people make better choices. So what is considered a good interior design, and what are the factors that make any interior space a good one? In this interior focus, we will explore this "good" side of design, looking at how architects ensured the needs of users by acknowledging accessibility, demographic diversity, economy, and the environment, regardless of aesthetic.

Heating and cooling buildings have always been two of the most important challenges in ensuring indoor user comfort. At a biological level, our bodies generate heat through metabolism, a physicochemical process. And although the human body has temperature regulation mechanisms, such as sweating and vasodilation, sometimes we need additional help to achieve thermal comfort. Therefore, since ancient times, traditional strategies have been sought to help achieve this, and many have been adapted to their historical and material contexts.
