Buildings: Renewable Energy Technologies Global demand for heating or cooling of island buildings for residential use, tourist use, offices and public buildings, absorbs, depending on the different cases, between 30 and 40% of electric production and between 10 and 15% of other conventional sources of energy (LPG, fuel-oil, coal...). This involves that 15-20% of the final energy consumed on islands, is used for climatisation, HWC.
Bioclimatic architecture is hard
to define, especially if seen not only from the structural
point of view, but from its relation with the surroundings. It can
even include exchanges of energy, water and wastes once the building
is finished. These concepts have been known since
ancient times and are found in the traditional island dwellings,
which show a huge repertory of building solutions generated
as a reply to an historical water scarcity. It is therefore
an inspiration source for the application of new solutions
that cannot be left behind.
The objective of the building is to
protect the inhabitant from external weather inclemency.
Nevertheless buildings have been transformed to a completely
closed space, without any interactions with the surroundings.
Instead of taking advantage of the climate and its
resources, energy-consuming devices are used to create an artificial
climate.
Bioclimatic buildings take into account
the comfort of the inhabitant, taking maximum advantage
of appropriate climate conditions, and reducing the energy
consumption of the building. To meet these requirements,
the following design criteria should be applied:
1) Solar Gain Control 2) These design aspects should be closely related to the use of active captation elements for the production of clean energy, as well as an overall policy of the building for the recycling, reuse and reduction of wastes. Moreover, the building interacts with its surroundings. Therefore the following aspects should be studied: 1) Building Adaptability 2)
Ecological foot printing and bioclimatic design By Mike Haslam As a designer or builder it is important that we are aware of the energy consequences of decisions made in the siting of a building, its form and the material choice. To give a stronger global perspective to this we should see these figures in the context of Eco-(logical) foot-printing which is about the fundamental inter-dependence of living together on our planet. We must also look at our community designs if we are to reduce our Eco-foot-print – creating communities that are less dependent on the car. This can be achieved through integration of housing with services such as schools and places of employment and through measures such as good connections to public transport and car pooling.Bioclimatic design - which looks at the appropriate passive design strategies to achieve internal comfort conditions - indicates that in our temperate maritime climate, passive solar design can help make these energy savings. Coupled with high levels of insulation and the correct balance of thermal mass, significant reductions in energy use demands can be achieved. This is a major step towards reducing our Ecological-foot-print and in combination with other strategies such as good community design and material choice we can really start to live sustainably.

Introduction to Bau-biology By Mike Haslam
Bau-biology, literally building-biology, started as a recognised
discipline in 1974 in Germany under Dr. Anton Schneider
and has since spread to New Zealand, the USA and in similar
forms to other parts of the world. Bau-biology attempts to illustrate paths and methods towards healthy
building, accordingly there are twelve principles involved
in this and in the creation of a healthy internal environment
- the Bio- climate:[C.ELDOC.6009314] READ 25 Principles

From Grey to Green: Creating Healthy Buildings by Balwant Saini Emeritus Professor of Architecture, University of Queensland, Australia Abstract The climatic unease in urban environments is brought by the overheating of the air, due to the heat, dust, pollutants from the city's activity, and to the network of the city. The center of the city absorbs 10% more solar energy than a corresponding green area, this is due to the concentration of constructions, the asphalt pavement and the high heat conductivity of most materials used, such as reinforced cement.[C.ELDOC.6009315] Design for a Solar Earth.

LET THE SUN SHINE IN The Art
of Daylighting By Daniel McQuillen Daylighting: Shedding
a New Light on Profitability
Innovative, utilitarian & alluringThe Teri complex in Domlur marks a novel paradigm in the creation of an energy-efficient and eco-friendly office space The concrete jungle that the once lush green city of Bangalore is
fast turning into, also boasts of an innovative building complex designed
to derive maximum benefits from nature’s basic elements and minimise
the demands on conventional energy sources. This alluring building complex,
that marks a novel paradigm in the creation of an energy-efficient, eco-friendly
office space, houses the southern regional centre of the New Delhi-based
Tata Energy Research Institute (TERI), an autonomous, non-profit organisation
actively pursuing research into the areas of energy, environment,
biotechnology, forestry and a whole range of sustainable development issues.
