The increasing use of air conditioning is causing many cities to hit record energy consumption levels during brutally hot summer months. In populous countries like India, China, Indonesia, Brazil, and Mexico, large urban centers function like ovens: buildings absorb heat that is re-released back into the environment, further increasing the local temperature. More heat outside means more air conditioning inside, which not only raises energy consumption, but also increases the levels of carbon dioxide in the atmosphere.

When we think of concrete, the color gray generally comes to mind. The traditional mixture of concrete, which comprises cement, gravel, sand, and water may vary in color depending on elements and admixtures but naturally varies from light to dark gray. However, compounds that add pigment to the mixture are becoming increasingly prevalent and popular,  as they infuse the concrete with hues more stable than paint. These shades result from the addition of oxides:  yellow, red and their derivations (eg. brown) are obtained with the addition of iron oxide; chromium and cobalt oxide create the greens and blues, respectively. For black concrete, it is common to use black iron oxide and carbon oxide combined with pozzolanic cement.

A sturdy featherweight table? Sounds… contrary to reason. But this contradiction was the very impetus for the design. Created for a research center that’s pushing the boundaries of design and manufacturing using technology and science, the designers–AIRLab, in collaboration with DManD— sought to dematerialise the typical structure of a table, creating a sense of instability with the visual counterpoint of a solid surface.

When the work finally comes to an end, the cleaning is done and preparations for the opening are underway, everything looks perfect. Coatings are all in their proper place, shining and with the intended color; wood surfaces are as yet unmarked and there is even a feeling of freshness and new life. Photographs mean that, for many, this vision of perfection is all that will ever be seen. 

The slightly trembling linework, the distinctive crossed corners, the parallel hatching, and the uppercase letters: it is undeniable that architects have developed a style of drawing over time. And though free-hand perspectives are no longer the only (or even primary) form of representation for architectural projects, they still have enormous importance during the design process. They are a design tool rather than a form of representation. 

The idea of turning cold, raw materials into elegant shapes has always fascinated artists, architects, and designers. In the Carrara marble sculptures of Lorenzo Berdini and Michelangelo, human forms were carved from heavy blocks of stones with great detail and precision. There is no difference in architecture: from taking a light volume off the floor, to leaving a small indentation between a structure and a fence, to altering the lining of a block, there are several devices to make buildings visually lighter.

Zinc is a natural element extracted from ores. Its symbol, which appears in the dreaded Periodic Table, is Zn. Through a metallurgical process of burning its impurities (reducing zinc oxide and refining), it assumes a much more friendly appearance, and later becomes the sheets, coils, and rollers used in construction. The main characteristic of this material is its malleability, which allows it to be worked easily, allowing to cover complex forms in facades and roofs of buildings.

Online courses have gained more and more recognition in the past couple of years. In addition to the flexibility and convenience of learning wherever and whenever you want, they provide access to content from well-respected professors and colleges. In the field of architecture and construction, online courses have grown exponentially. Last year, we compiled a list that focused mainly on constructive and material techniques. This time we selected 15 online courses covering a range of subjects. We hope this selection of courses can help you with your next project.

Alvaro Siza orchestrates, like no other, the experience of the visitor in his works. By means of compressions and decompression, openings and closings, volumes, voids and light, the Portuguese architect marks the paths, points of view, and perspective of the passage of time. In this photo essay, Ronaldo Azambuja photographed the Iberê Camargo Foundation ten years after its inauguration.
