Evolving urban conditions call for an evolving builtscape, and retrofits have been a key mechanism to allow buildings to adapt and respond to new needs. Amidst global environmental concerns, climate retrofits have become a popular strategy to upgrade buildings based on improved operational efficiency. Global decarbonization plans have even called for city-wide retrofits, such as in the case of London, to meet civic goals. While such upgrades significantly reduce energy consumption, they often come with a hidden cost - embodied carbon in retrofit materials and the potential for future waste.

Through the analysis of an innovative bamboo grid structure created using augmented reality by architects Kristof Crolla and Garvin Goepel in August 2023, we delve into the intricate world of bamboo architecture, focusing on its application in dome structures through a series of detailed illustrations that uncover the depth of this sustainable material's capabilities.

Increasing urbanization, excessive waste production, excessive consumption of material goods, and exploitation of natural resources. There are many factors that contribute to the environmental impact of humans on Planet Earth. Scarcity of raw materials and the use of non-renewable resources is already the reality of some locations, and nature can no longer reclaim renewables at the same pace as it is exploited. The impact of human activities is so remarkable that scientists have pointed out that we are living in the new geological age of the Anthropocene (the Greek word for “the recent age of man”). The construction industry in particular is a major resource consumer and waste generator. In the European Union, the construction and use of buildings represents about 50% of all resource extraction and energy consumption, and about one third of all water consumption. [1] In 2014, 52% of all waste was attributed to the construction sector. [2].

Accurate surveys are essential for an architectural project and subsequent construction to run as smoothly as possible. They provide detailed information on the physical characteristics of a site, existing structures, environmental conditions and possible obstacles, which will serve as prerequisites for the design stage, ensuring that all relevant factors are considered before construction begins. This information is vital for making informed decisions that harmonize with the environment and comply with local zoning regulations, building codes and environmental standards. Traditionally, these surveys have relied on manual measurements with tape measures, basic photographs, and, more recently, expensive laser scanning. All of these are susceptible to human error and can be extremely time-consuming, especially in large or complex areas. Laser scanning, despite being more accurate and comprehensive, involves expensive equipment and specialized technicians, increasing project costs and often extending the time needed to carry out the survey. 

As we near its 100th anniversary, expanded polystyrene (EPS) has become widely used in various industries and applications, especially in construction. Since 1970, EPS has been used in building construction due to its thermal insulation properties, lightweight closed-cell structure, durable strength, and long-term integrity. However, while these qualities make it highly useful and easy to recycle, they have also sparked debate due to recurring discussions about its degradation processes and environmental impact from various perspectives.

In today's construction industry, achieving energy efficiency, sustainability and safety along with aesthetics are essential goals for architects and consultants. Exterior Insulation and Finishing Systems (EIFS) are versatile, high-performance solutions that meet these requirements for both new builds and renovations. These multi-layered exterior insulation systems significantly enhance thermal performance and offer energy savings of up to 50% while providing flexibility in design.

Anyone who lives in a big city may have dreamed of moving elsewhere and living isolated, in a house among the trees or on a deserted beach. During the pandemic and the endless months of quarantine, many more may have had this same idea. As romantic and seductive as this may seem, however, living deep in nature comes with some important practical challenges. Rarely would anyone give up the little comforts they are used to, like turning on a faucet or charging their cell phone. If the location is, in fact, remote, it may not have electricity, drinking water, gas, sewage, or solid waste collection. But there remain several possibilities for a life with comfort and without neighbors. What are the main solutions to enable this and how can an architectural project provide an off-the-grid life?

Slate is a metamorphic natural rock composed of clay minerals such as mica and chlorite, which give it a laminated texture and predominant shades of gray, black, and green. Widely used in the construction industry, it is known for its durability and distinct elegance, offering a timeless and sober finish for roofs and exterior walls. With its unique texture, it can transform the look of any structure using rectangular—or other shaped—pieces. Additionally, it is a highly resistant material to weather, fire, and environmental pollutants, ensuring long-term performance with minimal maintenance. Its eco-friendly production process, involving only raw material extraction and minimal processing, reduces CO₂ emissions, making it an ideal choice for sustainable contemporary architecture.

When addressing the world's broader problems—such as the climate emergency, energy crisis, and housing shortage—, we often seek sweeping, grand solutions that could tackle them all at once. As alluring as these ideas may be, they eventually run into the thousands of complexities and interconnections our world presents. But what if we sought more decentralized and domestic solutions? Chicago-based firm Tom Bassett-Dilley Architects has been pursuing just this, focusing on sustainable design, carbon-free and energy-efficient projects for residences, historical buildings, institutions, and commercial projects. In their Manifesto: The New American Dwelling, they argue that the single-family home, once the great American dream, needs to be redefined to emphasize minimalism, efficiency, health, connection with nature, durability, and personal kindness, moving away from wasteful, artificial, and toxic practices. We spoke with Tom Bassett-Dilley, FAIA, CPHC, LFA, and founder of the firm, about some aspects of their work.

The notion of well-being goes far beyond the absence of disease. It encompasses physical, emotional, mental, and social aspects, reflecting a state of harmony and balance in all these areas. Pursuing well-being is a continuous process that requires comprehensive attention and care for the body and mind, and contact with nature or self-care rituals can also contribute. Indeed, in today’s fast-paced world, dominated by digital devices and urban life, in which truly disconnecting is very difficult, finding moments of peace and connection with oneself and nature has become increasingly important. Integrating well-being practices into outdoor environments offers an attractive solution, combining the therapeutic benefits of natural settings with cutting-edge wellness technology, providing a holistic refuge that nurtures the body and soul, and inviting individuals to relax and reconnect with the world around them.

“Embodied carbon accounts for 75 to 95 percent of the greenhouse gas emissions from landscape architecture projects,” said Chris Hardy, ASLA, PLA, senior associate at Sasaki, during the third in a series of webinars organized by the ASLA Biodiversity and Climate Action Committee. But by selecting locally made low-carbon materials, landscape architects can significantly reduce the climate impacts of their work.

The history of the use of lime in the construction industry dates back thousands of years, spanning cultures and communities worldwide. In fact, around 4000 B.C., the ancient Egyptians used quicklime mixed with water as a building material for their pyramids. Although lime has multiple applications in the food and agricultural industries, as well as in chemical, mining, and steel industries, in architecture it is one of the main construction materials due to its versatility, adhesion, waterproofing, workability, performance, setting, and durability, which allow for the creation of masonry mortars, interior or exterior plasters, among other functions.

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.

Although the sensory approach in the built environment is often based primarily on visual aspects, such as color and light, as we delve deeper into the relationship of architecture with the senses other essential elements emerge, such as aromas, textures, sounds, and even flavors. These components are fundamental to creating a profound experience between the user and the environment in which it takes place, demonstrating that design and sensory experience are intrinsically connected.

Although an architectural project comes to life with palpable materials, it is also defined by intangible qualities that give it richness, dynamism, and liveliness. Among them, the interplay of light and shadow can transform environments and affect their perception, determining the user's spatial experience. Besides providing natural ventilation, privacy, and thermal comfort, lattices allow this duality by filtering the entry of sunlight while projecting repetitive figures on the surface. In this way, perforated walls and ceilings can create multiple geometric patterns of light and shadow that become design elements capable of generating unique atmospheres.

Insulation plays an essential role in today’s buildings—whether it is to provide thermal efficiency to reduce energy demand and cut carbon emissions, or to reduce noise transmission to provide acoustic comfort. Every building has different requirements for the type of insulation needed in floors, roofs, ceilings and walls, and to meet these varying demands Kingspan has developed a range of holistic insulation solutions fit for the future of the built environment.

In the hustle and bustle of modern life, with deadlines, goals, and performance, finding moments of tranquility is essential for maintaining overall well-being and peace of mind. These moments provide a necessary break from daily stresses, allowing the mind and body to reset and thoughts to reorganize. Rituals of relaxation can create a sanctuary of calm amidst the chaos, promoting a sense of balance and peace, providing a healthier and more harmonious lifestyle, and contributing to better physical and emotional health. However, these rituals need not be expensive or complex.

A recent study suggests that our home galaxy, the Milky Way, cannot be seen by one-third of humanity. Why? Millions of city lamps brighten our cities every night, but only part of their light is used to actually illuminate streets or sidewalks – the rest is lost and emitted above the horizon, brightening the night sky and contributing to what is known as light pollution. However, as the artificial glow from towns and cities increases every year, the consequences of this urban phenomenon go beyond just preventing us from seeing stars. Other harmful effects include: causing a hazardous glare that can reduce safety, excessive energy consumption, waste of money and resources, disruption of ecosystems’ natural day and night cycles, suppression of melatonin production and several negative repercussions on public health. In this sense, choosing the right lamps (with a well thought-out design) is crucial to reduce light pollution.
