SUSTAINABILITY IN ARCHITECTURE
FOUR OPERATIONAL PRINCIPLES
- The human impact on nature should not exceed the carrying capacity of nature.
- The use of renewable resources must not exceed their rate of regeneration.
- The use of non-renewable must be compensated by the production of renewable resources, which will eventually have to replace them.
- The emission into the environment must not exceed the absorptive capacity of the athmosphere.
Improves human well-being and social equity, reduces the harm to the environment and is resource efficient.
It focuses on the resource cycle and it is based on the reuse, repair, remanufacturing and recycling of materials and products, against the use of virgin raw materials.
consumption of scarce materials and non-renewable energy
in the sense of remodeling, rehabilitate, reuse the existing
is to transform materials that allow use in the production cycle
It studies the environmental impact os a product from its productionto its dismanting, for this, it is necessary to know the energy consumption and the pollution to the environment of the various processes that make its use possible:
- the extraction of the raw materials necessary for its production
- the manufacturing process
- the transport
- its implementation and use
- its end of life
It studies the amount of territory needed to generate the biological resources consumed and to absorb the waste that an activity needs and produces.
Connection between human biology and the environment.
The relation with nature influences positively our mental state. We need to take into account the proportion of spaces, the relation height- with-length of the rooms and the range of colour when constructing a building.
Sick Building Syndrome
Set of symptons that can develop into a chronic illness. This symptons affect a 20-30% of the people living in a building. The risk factors can be: biological, chemical, physical or psychosocial.
The energy and health of a person is largely dependent on the place he lives in. The atmospheric conditions stimulate or depress the physical and mental work of the man. The main elements of the climate environment that influence human confort are:
- The temperature of the air
- The radiation, thermal emission
- The movement of the air
- The relative humidity
There are environmental conditions that are fundamental in the interaction of the building:
- Prevailing winds
- Relative humidity and vapour pressure.
In addition to the environmental problems, the great industrial development has led to the loos of skills and know-how accumulated over centuries.
Baubiologie aims to minimize the negative impacts of constructionsboth on the health of the occupants and the environment.
People-centered, energy-efficient buildings with functional and flexible spaces, using safe and recyclable materials, respecting the territory and its identity.
Characteristics: attention to insulation and thermal inertia, passive installations, water savings and recovery, healthymaterials, acoustic and sunlight control, natural lightingand ventilation, open spaces.
BIOCLIMATIC represents a working method which directs the project to achieve sustainability and bio-architecture objectives.
The control of the micro-climate in the different seasons can be obtained with passive and sustainable measures. We can use:
- Hindering direct solar irradiation throught windows
- Adequate orientation of the building
- Type of building favoring natural cross-ventilation.
- The use of clear finishes to promote reflection
- Thermal inertia of the building.
Traditional materials guarantee a greater well-being compared to synthetic materials. We have to be cautious because they sell some materials with harmfull chemicals as “naturals”.
DO NOT BE FOOLED!
Biomorphism is used as the most consistent project option with bioarchitecture. But not every bio form has bio essence!
The globalization of sustainable constructive solutions that are applied indiscriminately in many contexts does not consider the cultural aspects, local materials, the specific environmental conditions of each site.
The use of “natural” materials as decorative resource for an exclusively aesthetic reason or for efficient installations that are neither dimensioned nor functional reveal a superficial approach to sustainability.
“Recycled” has become a very common term within sustainability architecture, but there are plenty of options more eco-friendly than recycling, such as rehabilitate, re-use, recover…
