Contributions and reductions in the use of microalgae (R. Cervera, J. Pioz)
This makes associated facilities also depreciated. Considered in this way, the
cost of A-PhBR would be amortized from the first minute construction.
• The educational value of the A-PhBR has a remarkable aspect, showing society
the life cycle of the algae and promoting environmental awareness.
• Contribute to the image and positioning of ecological spirit, which is an
intangible that many organizations appreciate.
Cultivation of microalgae in architecture on one hand makes or produces and on the
other reduces or minimizes. What biomass provides is biomass that can be used to
obtain different products depending on the conditions of cultivation and further pro-
cessing. The microalgae biomass can be the basis for production of biogas and elec-
tricity through co-generation; which can be transformed into value-added products,
such as pharmaceuticals, cosmetics and alimentation for humans and animals; can be
used as bio-fertilizer and bio-stimulant in the agriculture and, ultimately, through a
process of further development and still uncompetitive, in bio-fuel. Subtractive or
fundamental action -minimizing algae and is unchecked technology to other renew-
able—is its ability to capture CO
2
and sink effect. Other qualities to be considered are
those relating to the ability of algae to purify water, thus contributing to the cycle of the
same, and for your help to save energy by thermal regulation as a living organism. All
this makes the A-PhBR today really economical, ecological alternative, and valuable
image, which is competitive for medium to large spaces, especially recommended two
market segments such as public institutions and large companies (Fig.

).
7.3 Building Scenarios of Application for A-PhBR
The city presents various opportunity scenarios for integrating bio-energy pro-
duction and various other products from algae. The greatest potential for insertion
of photo-bioreactors is in buildings; however, the urban scenario also offers
interesting opportunities as described below:
