Green Building as a process
The BASS commitment to the environment goes far beyond the use of low-impact materials and systems, being a fundamental point the reduction of CO2 emissions throughout the construction process.
We procure responsibly on the basis of Life Cycle Analysis of materials and labels and/or environmental statements of recognised prestige (FSC, BES6001:2008, recycled materials).
In this way we verify the sustainability of all processes in the supply chain, from the main structure to the final finish of the home.
Another key point for the minimization of emissions is the use of low carbon or zero carbon technologies in the conditioning of the home. For each project, a complete feasibility study is carried out that allows us to select the best energy source according to the internal needs of the owners and the environmental conditions of the site. This study allows us to choose between systems such as high-efficiency aerothermal heating for radiant surface air conditioning or other green technologies.
Likewise, the bioclimatic design of the complex minimizes energy needs and therefore considerably reduces the carbon balance during the useful life of the home.
Talking about ecological construction means talking about bioclimatic design, environmentally friendly materials and energy efficiency.
The strength of tradition
The bioclimatic design analyzes the microclimatic characteristics of each place in order to take advantage of natural resources and passively achieve optimum comfort conditions and reduce energy consumption and environmental impact to a minimum.
At BASS we have advanced energy simulation software and design tools such as climograms, which allow us to individualize the study of each home and detect the best strategies.
1. Topographic Integration
Each plot is studied in detail in order to achieve complete integration of the built volume and topographical elements such as slopes, beds, trees, etc..
2. Passive solar design
BASS has an advanced system of climatic data analysis capable of calculating to the precision the schedules of capture and solar protection of the house, designing geometric forms adapted to improve the performance and comfort of the same.
Depending on the climatic data obtained, the orientation of the main façade, its location and the selection of tree species in the gardening design are determined.
Likewise, a correct solar design allows us to promote natural ventilation by means of elements equivalent to solar chimneys.
3. Circular ventilation: the courtyard
BASS modernizes the courtyard, a traditional concept present in the vernacular architecture of the Mediterranean, from the domus of the Roman emperors to the Nasrid palaces of the Alhambra.
This compositional element, thanks to its hygrothermal behaviour, naturally moderates daily thermal oscillations, stabilising them until temperatures closer to comfort are achieved. In addition, it allows the integration of different bioclimatic strategies, especially significant in summer regime:
– Cross ventilation: Regardless of the geometry of the house there is a pressure differential between the courtyard and any of its facades which guarantees cross ventilation in a natural way.
– Radiant cooling: On summer nights, the patio is capable of dissipating a large amount of accumulated heat to the outside by means of radiation, storing this cold in the pavement.
– Evaporative cooling: Shade elements together with the incorporation of water sources or plant elements, achieve a decrease in the daytime thermal sensation, in summer, of up to 10 ºC.
4. Natural ventilation
The combination of the calculation of the openings, the passive solar design and the courtyard, allows us to guarantee the natural ventilation of the house, either for sanitary purposes or to reach during a great part of the year, without any type of active system, the hygrothermal well-being.
The materials used in our construction system have been carefully selected on the basis of three fundamental parameters:
1. Environmental footprint and life cycle analysis (LCA) of materials.
The building process has a high impact on the environment and human health due to the consumption of natural resources and energy, the emissions generated and the impact on ecosystems. Our aim is to minimise the set of effects associated with the extraction, manufacturing, transport, installation and end of life phases of materials.
2. Useful life and durability of materials and construction systems.
Key factors to take into account are the energy incorporated in the production of building materials and systems, their useful life, their recyclability once finished, their autochthonous character, as well as their renewable character. Hence the choice of noble and environmentally friendly materials such as wood, natural cork, lime, silica, magnesium or graphite.
The natural materials and systems used are the best guarantee of aging of our constructions and the best prevention against the most common pathologies in conventional construction (infiltrations, condensations, ascensional humidities or low indoor air quality).
3. Health Benefits.
The set of materials and ecological finishes help to reduce diseases such as rheumatism, allergies and many disorders related to the respiratory system. In addition, the natural bioelectric field of wood provides a state of equilibrium in the human body, something especially beneficial for people suffering from nervousness, insomnia, migraines and headaches. In addition, these materials absorb the electromagnetic waves received from the outside, reducing the stress levels of its inhabitants.
Energy saving is one of the quality pillars of BASS. We approach design, execution and after-sales in a global way, focusing on all those aspects that allow a reduction in energy consumption.
Fundamental aspects of high energy efficiency:
1. Low-carbon technologies.
They represent a significant reduction in emissions and considerable savings in energy consumption. A BASS home is not only comfortable and healthy, it is also easy and economical to maintain.
2. High Performance Thermal Enclosure.
The benefits of a thermal enclosure are:
Great thermal insulation.
It triples the requirements of the recently approved regulations and multiplies the current real estate market tenfold.
Health and well-being.
Thanks to the use of both biocompatible and breathable materials and suitable systems we can minimize, and even eliminate, the presence of electromagnetic radiation.
High acoustic insulation.
The BASS SYSTEM® construction system minimizes acoustic vibrations, making a BASS home a haven of peace. This translates into less stress and a better quality of life.
