How Breathable Should Facades Be? Exploring Permeability and Impermeability in Building Envelopes

March 21, 2024

The main role of architecture is to create structures that protect us from the environment and create spaces that are safe and comfortable for all types of needs and activities. By providing shelter, architecture also shapes the way people interact with their surroundings. Building technologies of the past rarely managed, however, to create a complete separation between us and the outside world.

While impermeability was a desired outcome, the porous building materials available always allowed some water, wind, or outside particles to leak into the interior spaces. In contrast, modern technologies now allow for almost completely impermeable building envelopes, allowing for complete separation between indoors and outdoors, thus relying on engineered systems to regulate temperature, airflow, or humidity. This article explores the differences between these two contrasting approaches, exploring how building facades are equipped to regulate indoor comfort and its environmental impact.

15 Projects in India Using Traditional Jali Wall Facades: Solution to Control Light, Temperature and Ventilation

February 14, 2024

Natural light, fresh air, and a constant, comfortable temperature. These are three of the most basic components we need in our interior spaces. By expanding and increasing the use of glass in contemporary building facades, we can increase natural light. However, to combine these wall-to-wall glazed surfaces with ventilation and temperature control, high-powered technical solutions are often required.

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.

Bringing the Outside In: Life-Size Terrariums and Other Ways to Exhibit Nature in European Apartment Buildings

December 06, 2023

As the temperature drops in the Northern Hemisphere, cold outdoor spaces are overcome with frost, ice, and snow, and we find ourselves rushing from one heated indoor environment to the next, less willing or less able to stop and appreciate the natural world around us.

Apart from dragging a spruce or fir tree inside and dressing it up in yuletide costume, we tend to leave the real natural world to its own seasonal devices until it reemerges in Spring. However, by inviting the positive effects of plant life into our homes, we can improve both our mental health and the air we breathe by filling them with peace and joy all year round, not just at Christmas.

What Are Clerestory Windows and Their Spatial Advantages in 24 Projects

August 16, 2023

Not nearly as complex an architectural typology as the word suggests, a ‘clerestory’ is a simple – if lexically loose – a portmanteau of ‘clear’ and ‘story’. Denoting a section of the wall that contains windows or cavities above eye level. The word is often assumed to have a religious context. Clerestories historically appeared at the upper levels of Roman churches, Hebrew temples, and early Christian architecture after all. And the earliest references we have to the feature come from religious texts.

Today, religious structures are often typified by the light their high windows allow to stream in, both figuratively and literally, from a higher source. At the CES Chapel in Taiwan, for example, ‘light diffuses through the glass clerestory and brightens the apse throughout the day,’ explains JJP Architects & Planners, about an interior design concept driven by natural lighting, ‘the chapel is filled with a spiritual aura, with a bright cross projected deep into the space.’

Tube Houses: 15 Projects Reinterpreting the Narrow Vietnamese Residences

February 15, 2023

Walking down the streets of cities like Hanoi and Saigon in Vietnam, you might encounter houses with surprisingly narrow facades in contrast to the stacking of three to five floors, with windows for ventilation and natural light only on the front facade. These are the famous traditional Tube Houses. According to ancient popular culture, this type of housing emerged due to property taxes being based on the width of the facade, but the true reason is to optimize land use, allowing a larger number of plots in the same square.

However, this legacy is now being recreated in contemporary designs by Vietnamese architects. Old facades give way to innovative solutions featuring atriums for natural lighting and ventilation, courtyards and interior gardens, greenery incorporated into different environments, split-levels, etc., allowing for high-quality spaces. With that in mind, we have put together a selection of Tube Houses, together with their respective section drawings. Check out below:

MVRDV Unveils Winning Design for a New Central Library in Wuhan, China

January 10, 2023

MVRDV, in collaboration with UAD, has been selected as the winner of the competition to design a new library for Wuhan, poised to become one of the largest libraries in China. The large-scale project creates diverse study environments and offers reading and studio spaces while also connecting to its surroundings via three large openings that display the life inside the buildings to invite visitors to enter. Spanning over 140,000 square meters, the distinctive building adapts its volume to reflect its position at the confluence of two main rivers in Wuhan and become a recognizable landmark for the city.

Strategic Green Spaces: How to Make the Most of their Cooling Effects

September 18, 2022

Urban green spaces are considered one of the most appropriate and accessible ways to mitigate the effects of rising temperatures in urban environments. As the global climate warms, cities worldwide face more frequent and extreme heat waves, putting their citizens at risk. Many cities are employing strategies for reducing the impact of urban heat islands, which are generated when natural land cover is replaced with surfaces that absorb and retain heat, such as pavements and buildings. This raises the temperature by several degrees compared to the surroundings. Cities have their micro-climate, influenced by this phenomenon combined with a series of often overlooked factors. For a climate strategy to be efficient, all factors need to be taken into consideration.

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

June 23, 2021

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.

How to Ensure Comfort and Well-Being in Small Spaces?

March 19, 2021

While some aspects of comfort and well-being in an indoor environment are related to external factors, such as natural lighting and ventilation, others are directly associated with the interior layout and the sensations created by architecture in the people living in that space.

It is always challenging to balance all of the elements that can provide greater comfort and well-being in interior design, particularly in small environments that must be fully optimized since it is not always possible to create large openings to the outside or even to accommodate the whole architectural program in a conventional manner.

Design Before Air Conditioning: A New Book Surveys Early Experiments in Climate Control

September 17, 2020

It’s easy to think of Modernism as inseparable from air conditioning, simply because we are surrounded by so much of it that is. A valuable reminder that this wasn’t always the case is provided in University of Pennsylvania architecture professor Daniel A. Barber’s Modern Architecture and Climate: Design Before Air Conditioning (Princeton University Press), which outlines the story of the febrile, flexible, and often-forgotten early experiments in climate control.

Cross Ventilation, the Chimney Effect and Other Concepts of Natural Ventilation

April 05, 2020

Nothing is more rational than using the wind, a natural, free, renewable and healthy resource, to improve the thermal comfort of our projects. The awareness of the finiteness of the resources and the demand for the reduction in the energy consumption has removed air-conditioning systems as the protagonist of any project. Architects and engineers are turning to this more passive system to improve thermal comfort. It is evident that there are extreme climates in which there is no escape, or else the use of artificial systems, but in a large part of the terrestrial surface it is possible to provide a pleasant flow of air through the environments by means of passive systems, especially if the actions are considered during the project stage.

This is a highly complex theme, but we have approached some of the concepts exemplifying them with built projects. A series of ventilation systems can help in the projects: natural cross ventilation, natural induced ventilation, chimney effect and evaporative cooling, which combined with the correct use of constructive elements allows improvement in thermal comfort and decrease in energy consumption.
