3. Renewable energy and sustainable urban design
The Preservation of environment and reducing the usage
of traditional energy has become the aim that must be
achieved whenever possible. The designers and
implementers of construction and in cooperation with
specialists in various fields related to construction
should consider in the beginning of the urban planning
project, designs ideas that allow getting internal
environment appropriate for the users of this
construction with the minimum amount possible of
energy especially electrical energy.
4. Renewable energy applications in the construction
1-Solar Power
2-Wind energy
3-Geothermal
4-Biomass (organic materials)
5-Water power
5. Solar power
Is heat that
reaches the
earth's
surface in
the form of
sunlight is
one of the
main
sources of
renewable
energy.
Figure[1]
6. Solar Power :
Solar heat that reaches the earth's surface in the form of
sunlight is one of the main sources of renewable energy non-
exposed to finish and can convert solar energy into other
forms of energy usable across five ways key: use direct
sunlight, focus solar heat, convert sunlight into energy
power. In addition to it main role in the revitalization of
some other renewable energy sources as the solar heat is
one of the cause of the movement of wind and because of it
organic materials grow which are used in turn to generate
clean energy. We can benefit of the sun's rays directly
positively or negatively in the construction as well as can be
benefit from them through converted into electrical energy
is clean in several ways.
Look at Figure[1]
7. Wind energy:
• Energy
received
from the
movement
of the wind
across the
earth. This
energy is a
result of the
heating of
our oceans,
earth, and
atmosphere
by the sun.
Figure [2]
8. Wind energy
• in the past , wind movement was used in the
operation of some equipment such as
windmills to grind grain or raise water for
irrigation . currently , wind power used to
move the turbines to generate clean electricity
that can be used for multiple purposes , where
the distribution of a number of these turbines
in the semblance of farms in the circumference
to construction or around the cities are stored
electricity generated and then distributed
through a network of electricity to buildings .
9. Geothermal
Is the energy
produced
from
geothermal
resources
Figure[3]
10. Geothermal
Geothermal
• Is the energy produced from geothermal
resources,is passed on the wire near the surface
of the earths crust, and can be used directly in
the protection of buildings from severe climate
fluctuations and other by establish buildings of
underground earth shetering. Also can be
obtained by drilling wells to allow the exit of
magma , hot water or water vapor, gases and the
resulting heat used in turn to run turbines to
generate electric power.
Look at Figure[3]
11. Biomass energy
It is the
energy that
can be
obtained
by using
some
organic
materials
such as
plants or
animals
waste
12. Biomass(organic materials)
• It is the energy that can be obtained by using some
organic materials such as plants or animals waste .
and it is a renewable energy because it is not need to
long periods of time for its composition, such as a
caol and petroleum. The oldest ways to get energy
from organic valley is the burning of wood and other
organic dry materials to grt the heat for cooking or
for heating or water heating, which in turn is used to
generate electricity . recently, animal waste or
dermal used through decomposition in the
anaerobic digester of the anaerobic digester to
produce some gases such as methane, which in turn
is used to run turbines to generate energy .
13. Water power
Diversion
of natural
water on
the surface
of the
earth to
kinetic
energy
14. Water power
Diversion of natural water on the surface of the
earth to the kinetic energy was used for some
purposes, but the wider use at present are by
converting the movement of water into electrical
energy, and it is done through three main
methods are:
1- hydro power collects falling water
2- hydro-schemes harness energy from fast
flowing rivers
3- tidal power stations

16. Example
1-Masdar city
• Masdar will employ a variety of renewable power
resources. Among the first construction projects will
be a 40 to 60 megawatt solar power plant, built by
the German firm Conergy, which will supply power
for all other construction activity This will later be
followed by a larger facility, and additional solar
panels will be placed on rooftops to provide
supplemental solar energy totaling 130
megawatts. Wind farms will be established outside
the city's perimeter capable of producing up to 20
megawatts, and the city intends to
utilize geothermal energy as well. In addition,
Masdar plans to host the world's largest hydrogen
power plant
