As a major driver of natural resource consumption, energy use, and greenhouse gas emissions, the construction industry has a significant impact on the environment, consuming 32% of global energy and contributing to 34% of global CO₂ emissions. Building materials play a crucial role in shaping the built environment. Through principles of circular economy, renewable and self-sufficient solutions, and technological innovations, analyzing the environmental performance of each material highlights the opportunity to review and assess the different stages of its life cycle.
By establishing a common framework for measuring and managing the environmental impact of building materials, Life Cycle Assessment (LCA) emerges as a key approach. This methodology provides a comprehensive evaluation of the environmental impacts associated with products, processes, or activities throughout their entire life cycle. From raw material extraction, manufacturing, and transportation to construction, use, and end-of-life treatment, the analysis considers the environmental burdens linked to each stage. In the context of building materials, LCA offers a holistic and systematic approach to assessing environmental performance and identifying opportunities for design optimization, among other improvements. In this way, it quantifies impacts such as carbon emissions, energy consumption, water use, air pollution, waste generation, and ecosystem depletion.
Operating in urban environments often requires us to make decisions regarding pre-existing structures. The increase in city density has directly impacted the availability of space for developing new and independent constructions, sparking debates about what stance to take toward built heritage that has become obsolete—either due to deterioration or because it no longer meets the functional needs of the contemporary population. In cases where buildings have seriously deteriorated or new projects differ greatly from the spatial possibilities an old building can offer, preserving only the façade—as an exterior envelope, almost like a superficial element—can be seen as a partial solution that allows for the preservation, in part, of the urban character of a structure if it holds some public or cultural value. The controversy arises, certainly, from the lack of relationship or connection between the transformed interior and the preserved exterior.
Concrete blocks are prefabricated materials primarily used for constructing walls. Similar to bricks, these blocks are stacked together and bonded with mortar, typically composed of cement, sand, and water. They are hollow inside to accommodate steel bars and mortar filling.
These blocks are available in a variety of dimensions and textures, ranging from traditional smooth surfaces to fluted or rough finishes. Additionally, there are special units designed for corners or beams with longitudinal reinforcements. The dimensions vary, from the classic 8x8x16 inches (approximately 19x19x39 cm) intended for structural use, to a size of 8x3.5x39 inches (approximately 19x9x39 cm) for partitioning walls. How can we creatively incorporate them into our designs?
Implemented as a means to take full advantage of space, built-in furniture has grown in popularity as well as ingenuity as designers tackle the needs and tastes of a wide range of users. It's ability to adapt and integrate into architectural spaces allows it, through a variety of configurations and materials, to fulfill various functions; however, this poses an interesting question. Is it truly the furniture that adapts to our living spaces? Could it not itself become the protagonist and creator of the spaces that we project?
How many times have you been faced with the challenge of designing a cultural center? While this may seem like quite a feat, many architects have had to design a program that blends a community center with culture.
Among the projects published on our site, we have found numerous examples that highlight different responses, from flexible configurations to sites that prioritize central gathering areas for citizens and activities. See our series of 50 community centers and their plans and sections below.
