U7-Sustainability in architecture

Basic concepts:

3 Pillars:




Green and circular economy:

Circular economy: Focuses on the Reuse, Repair, Remanufacturing and Recycling of materials and products, against the use of virgin raw materials.
Green economy: It improves human well-being and social equity, reduces environmental risks and is resource efficient. It is a model that integrate the social dimension and the conservation of ecosystems.

Four operational principles:

How to act in a sustainable way?Human impact on natural systems must not be greater than nature’s carrying capacity. Renewable resources must be used at a pace that does not surpass their rate of regeneration. Nonrenewable resource usage must be offset by the generation of renewable resources, which will eventually have to take their place. The discharge into the environment must not exceed the receivers’ absorption capability.

-Life-cycle analysis:

It investigates a product’s influence from conception to disposal. To do so, you must calculate the energy consumption and associated emissions to the environment of the numerous processes that allow its use:-extraction of raw materials -manufacturing process -packaging, transportation, distribution -use stage-end-of-life

Ecological footprint:investigates the land necessary to manufacture the resources required to make a specific product, as well as the land consumed by activities and requirements.

_3R:Reduce the use of nonrenewable energy and limited materials. Reuse in the sense of remodeling, rehabilitating, and repurposing what already exists. Recycle refers to the process of transforming materials such that they can be used again in the manufacturing process.

Healthy buildings:

Human biology and the environment are priorities in these buildings, which architects must bear in mind while designing them. In terms of human psychology, architects must be aware of the significance of proportions, dimensions, colors, and natural relationships.Because of how it impacts us to live in a certain environment.Those can be -proportion of space-chromatic atmospheres-texture of materials-exterior views.Sometimes the opposite can happen with the Sick building syndrome with skin reactions, headaches, nausea, eye irritations, and respiratory tract, tiredness, irritability, vertigo.


Climate is important to us as humans. This means that the weather has a significant impact on our physical and mental wellbeing. This is because human bodies are thermal systems that generate heat when chemical energy is converted into mechanical energy. As a result, the less effort we use to keep our bodies warm, the closer we will be to comfort.Interactions:-temperature-sunshine-prevailing winds-rainfall-snow-relative humidity -vapour pressure.

Sustainable design:

Bio-architecture is one example. This style of architecture focuses on the people who live there, as well as the environment and the city’s identity. It is built in an environmentally sustainable manner and features natural-inspired buildings. On the other hand, there is bioclimatic architecture, which is based on a climate analysis of the location where a structure will be constructed.


We have been shown that the use of natural materials in the long run is better that the use of synthetic ones.
