HABITAT AND COMFORT - ARCHITECTURES OF THE AIR

Living in comfort

This design studio proposes comfort as the main issue in the design of the collective habitat. Discussing comfort places the inhabitant and his body, along with their interaction with the environment, at the centre. The body is no longer thought of as an isolated and separate entity but as connected and linked to the world. This interaction takes place through the air.

Design with air

Invisible, almost immaterial, air could be considered the least architectural of the four elements. However, architecture is essentially habitable air that is conditioned to be filled with cultural meanings. The functions of air are many. Like water, it acts as an elemental fluid; like earth, it can become an insulating element; and like fire, it can make environments uninhabitable. Hence the importance of studying strategies to control air in order to put it at the service of human life.

Arrenging matter

The aim is to develop a design that effectively integrates the statics of materials with the thermodynamics of air, both essential elements for significantly improving the comfort of spaces. Solid matter not only arranges and shapes fluid matter but also interacts with it according to the properties of the materials, thereby regulating environments thermally and hygroscopically, attenuating noise, and facilitating processes such as air convection.

Climate responsive habitat

This approach allows the adaptation of the habitat to the environment and incorporates the natural cycles of the seasons by transforming external conditions such as temperature, relative humidity, and air velocity through the design of passive systems. Factors such as the geometry of the space, solar radiation, the presence of vegetation, solar protection, and, most importantly, the openings that create air inlets and outlets, will be decisive in designing this active void and the resulting microclimate

Domestic monumentality

The studio conceives this active void as a necessary volume of air that is no longer residual or simply the negative of the built space, but has its own consistency, is designed with other laws - the laws of thermodynamics - and acquires a common dimension, which escapes the human scale to achieve energy efficiency. We are talking about a kind of monumentality inscribed in domestic architecture. This internal spacing offers the opportunity to renaturalise the interior of buildings through plants, trees and bushes that improve air quality and encourage contact with life and nature. This contact has been shown to reduce stress, improve mood and contribute to people's mental and emotional health and well-being. Rethinking circulation spaces as biophilic environments changes the prevailing perspective: they are no longer spaces to be cared for but spaces that care for us.

Social condenser

The recognition of interdependence and the impossibility of being an autonomous and self-sufficient individual lead to a relearning of how to view the world, not from the narrow and focused perspective of an individual, but through the eccentric lens of shared, communal life. These bioclimatic spaces, strategically placed in relation to the building's circulation flows, also provide a social return. Being situated near inhabited areas, they foster sociability over anonymity and act as social condensers.

Shared habitat

The study focuses on these interstitials areas around the house to explore the social and environmental potential of these transitional bioclimatic spaces, capable of reducing energy demand and generating mutually supportive environments that foster relationships between people. The tempered and bioclimatic condition of these spaces allows us to rethink the house from its internal limit and to review dualities such as interior/exterior, private/communal, owned/shared, open/closed to incorporate other forms of contemporary life in a shared habit

WAYS OF LIVING

Jevons paradox

Currently, the focus on efficiency as a sustainability strategy has led to a situation where, despite dwellings are becoming more efficient per square meter, the overall consumption of resources has not diminished. This phenomenon is known as the Jevons Paradox, in which improvements in efficiency per square meter result in increases in floor area per person, thereby maintaining overall consumption levels. In response, the course syllabus shifts its focus from efficiency to sufficiency in population density, setting a maximum allowable space of 30 m² net per person and defining the minimum number of users per project by dividing the gross area by 40m².

Sharing

To ensure quality of life is not compromised, the reduction in net surface area per person can be offset with shared spaces. To achieve this, each unit could either transfer more private space to the shared spaces or share it with more users. The course syllabus encourages rethinking the various scales of cohabitation, acknowledging that not all functions are suitable to be shared by the same number of users. Sharing can occur at a cluster level, across a floor plan, or throughout the entire building. Consequently, the more space that is shared, the larger the living areas available the users can enjoy. The aim is to match or exceed current standards in a sustainable way.

Minimum net surface areas for private units

• 20 m² for one person (one room)
• 35 m² for two people (two rooms)
• 50 m² for three people (three rooms)

All units will include a bathroom and a kitchenette.

Spatial mechanisms

Spatial mechanisms could be incorporated into the typologies to help perceive the spaces as larger than they are. This can be achieved through the implementation of double circulations, diagonals, interconnected rooms or multiple access points. These features endow housing with contemporary attributes such as porosity, de-hierarchisation, indifferentiation, inclusivity and flexibility.

Biophilia

On the other hand, it is recommended to explore living arrangements in common spaces that foster human interactions beyond the private unit. Organize shared spaces strategically to encourage encounters and redesign transition areas as biophilic environments that promote engagement with life and nature.

Bioclimatic strategies

In contrast to a regulatory framework that promotes only mechanical efficiency and active systems using renewable energy, the collective dimension of these intermediate spaces enables the implementation of environmental and thermodynamic strategies. These include designing buildings with bioclimatic courtyards and atriums that modify the building's form factor and passively lower energy demands. Today, we have the capability to measure, quantify, and simulate fluid dynamics and analyse various parameters to ensure comfort.

WAYS OF BUILDING

Material systems

Depending on the selected site, each group will be assigned a specific material for analysis, which will play a critical role in their future projects. Each team will work with a different material, delving into its manufacturing processes, energy requirements, and raw materials used. The properties and characteristics of these materials will be thoroughly examined. Furthermore, the study will extend to assembly methods, aiming for a comprehensive understanding of the construction systems associated with each material. This accumulated knowledge will lead to the creation of an atlas, which will be shared among all students

Measuring

Each group will work on developing constructive solutions for the project envelopes. How these solutions interact with the spaces will be evaluated, both in the relationship between the interior and exterior and in the thermodynamic intermediate spaces. The purpose will be to analyse and measure the ability of the solutions to provide comfort, focusing on aspects such as insulation, inertia, humidity regulation and noise absorption

Form follows material

The approach involves working within a paradigm where form responds to material, performance, thermodynamics and biohabitability.

To ensure the efficiency and sustainability of architectural solutions, it is proposed to quantify transmittance, inertia, thermal lag, life cycle analysis and cost, using simulation measurement methods.

CLIMATE AS SITE:

The aim of this semester, is to explore how climate shapes architecture. Consequently, instead of selecting a specific physical site, we will engage with a conceptual grid that represents a non-place, thereby emphasizing the importance of adapting to the climate

We will define five distinct scenarios, each representing a climate type according to the classification by the Russian-German climatologist Wladimir Köppen: Tropical (A), Arid (B), Temperate (C), Continental (D), and Polar (E).

Groups will be formed, with each focusing on a specific climate. Using climate charts, we will analyze temperature, humidity, precipitation, and air movement to understand the challenges each climate presents. Additionally, we will examine the mechanisms and strategies of traditional vernacular architecture across different cultures, aiming to achieve comfort and effective adaptation to various climates.. This analysis will culminate in the creation of a climate atlas, which will provide the groups with an in-depth understanding of the various architectural solutions developed to address climatic challenges.

Thereafter, each group will specialise in a specific bioclimate and design an architectural space adapted to the climatic conditions of their assigned bioclimate. In this way, the groups will have the opportunity to explore and understand various bioclimatic design strategies, based on the climatic conditions characteristic of each region

DOCUMENTS

The student groups will have to produce a series of documents, including: site plan, inhabit plan, climate or material atlas, thermodynamics, human vs urban scale, and atmosphere.

This work will be conducted within the framework of integral sustainability, which transcends the mere aggregation of its three dimensions environmental, social, and economic sustainability to represent their common denominator. This means that solutions will be developed to address all needs without compromising any. To achieve this, strategies will be implemented that affect multiple aspects simultaneously, such as:

• Reducing  to influence economic and environmental factors,
• Spacing with bioclimatic intermediate spaces to address social and environmental concerns,
• Sharing to tackle social and economic issues concurrently

Site plan

Each group of students will work on a different site from the various adjacent sites of the conceptual grid, and their climatic chard should conclude with a group model and site plan explaining the relationship of each proposal to its context through different scales..

Inhabit plan

The document will focus on cluster typology with shared spaces at various scales of cohabitation, shifting the emphasis from reflection on dwelling to the transition between private and common spaces, rather than studying them separately

Climate atlas

Each student group will analyse a material, studying its manufacturing process, properties, and perception at different scales (POWERS OF TEN), and will propose a construction system, which will be explained through an axonometric drawing and analysed using a simulation program. The analyses of the materials of all the groups will be compiled into a common atlas for the group

Thermodynamics

This involves developing a perspective section that considers the thermodynamic operation of the building and its behaviour in both summer and winter. The representation will include fluids and comfort parameters such as temperature, relative humidity, air velocity, and thermal inertia

Human scale vs urban scale

A constructive section of the project that explains the relationship between the chosen construction system, human scale and urban scale

Atmosphere

This document features an image or representation of the interior environment that captures the materiality, the influx of natural light, and the appropriation of the space. The choice of technique is flexible; it may include a render, a photograph of a model, or a collage
