The document discusses zero energy buildings and renewable energy sources. It defines a zero energy building as one that generates as much energy through renewable sources as it consumes from the grid. It notes that solar and wind energy will be the major contributors for zero energy buildings due to their widespread availability. While biogas can also be used, it requires large quantities of waste and is not feasible everywhere. Geothermal energy has great potential but more research is still needed to fully tap into its capacity. The document concludes that solar and wind will be the primary renewable sources for powering zero energy buildings.

2. REASONS FOR CONCERN
1. Standards of energy efficiency in almost all
part of the world is extremely low.
2. Most of the countries are heavily dependent
on imported oil, a finite resource that is likely
to be increasingly expensive in future;
consumption also has significant
environmental costs.
3. Many of the developing countries have
serious balance of payments problem.

3. Buildings are the Largest Energy Consumer

4. 1. A net zero energy building can be defined as a
building which generates as much energy
through renewable sources as much as it
consumes from the Grid.
2. During the last 20 years more than 200
reputable projects claiming net zero energy
balance have been realized all over the world
which extensively utilise the non renewable
energy sources to earn the tag of ZEB.

10. Various forms of renewable energy
Solar Energy
• The photovoltaics convert the
light energy directly into
electric energy by
photoelectric effect at the
atomic level.
• The solar thermal collectors
chosen for this job are flat
plate collectors with an
efficiency factor of 0.8 and a
linear heat loss coefficient
factor of 3.5.

11. Wind Energy
• The total kinetic energy
available from wind
world-wide is more than
80 times the energy that
is being consumed now.
• The wind turbine costs
are approximately the
same as coal-, natural
gas-, and nuclear-based
electricity.

12. Geothermal Energy
• The temperature of earth
varies proportionally with
depth. We can utilize this
temperature to produce
limitless energy.
• One percent of the heat
contained in just the
uppermost 10 kilometers of
the earth’s crust is
equivalent to 500 times the
energy contained in all of
the earth's oil and gas
resources.

13. Biogas
• It is the most
suitable energy
resource as per
environmental
concern.
• Suitable for rural
areas where plenty
of organic and
inorganic wastes are
available, no proper
discharging channel
is not available.

14. Comparison
Economical comparison
shows that wind energy is
most economical amongst
all renewable resources
mentioned in the graph.

15. Conclusion
• Solar and Wind energy will be the major contributor
of renewable energy for ZEB’s owing to their
widespread availability.
• Biogas can also be used for our energy needs but its
only constraint is that it needs huge quantity of waste
and it is also not feasible everywhere.
• Geothermal energy is an upcoming form of energy
having great potential to generate electricity but a lot
of research still has to be done to tap into its full
potential. IEI ppt (asif,apurva,archana,arpita)
