3.  Zero energy refers to the consumption of zero energy from the production but by utilising the energy generated
by using the renewable sources of energy that are freely available in the atmosphere such as solar energy, wind
energy, rain water harvesting etc.
INTRODUCTION
 A Zero Energy Building (ZEB), also known as a Net Zero Energy (NZE) building, is a building with net zero
energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the
amount of renewable energy created on the site or in other definitions by renewable energy sources offsite,
using technology such as heat pumps, high efficiency windows and insulation, and solar panels.
 In the history of our planet periodically climate change has happened before but for the first time these changes
associated with human activities. Carbon dioxide (CO2) that is emitted during the combustion of fossil fuels
changes the composition of our atmosphere. The uncontrolled use of fossil energy leads to the depletion of
world reserves of non-renewable energy sources. The area, where it is possible to reduce the consumption of
fuel and, consequently, energy consumption and emissions into the atmosphere, is the housing stock, which
according to various estimates consumes 30 to 40 % of all energy.

4.  The goal is that these buildings contribute less overall greenhouse gas to the atmosphere during operations
than similar NON-ZNE buildings.
 The development of zero-energy buildings is encouraged by the desire to have less of an impact on the
environment, and by tax breaks and savings on energy costs that make zero-energy buildings financially
viable.
 The development of modern zero-energy buildings became possible largely through the progress made in
new energy and construction technologies and techniques.
 These include highly insulating spray-foam insulation, high-efficiency solar panels, high-efficiency heat
pumps and highly insulating, low emissivity, triple and quadruple-glazed windows.
 These innovations have also been significantly improved by academic research, which collects precise
energy performance data on traditional and experimental buildings and provides performance parameters
for advanced computer models to predict the efficiency of engineering designs.

1. Parker D.S. et.al. On the path to Zero
Energy Homes. 2001
 Parker and team during times of peak demand, concluded that on
a study of energy consumption as a Zero Energy Home generated
more power than the house uses, thereby reducing power demand
on the utility provider. During times of power outage, the home
generates its own power, allowing the homeowner essential
energy security.
 In a Florida study, a prototype Zero Energy Home outperforms a
conventional model by providing almost all of its own power
needs throughout the year.
2. J. Laustsen Energy Efficiency Policies
for New Buildings. 2008
 According to Lausten The Net Zero Energy Buildings are
buildings that over a year are neutral, meaning that they deliver as
much energy to the supply grids as they use from the grids.
 Seen in these terms they do not need any fossil fuel for heating,
cooling, lighting or other energy uses although they sometimes
draw energy from the grid” The issue of large storage, energy
losses either in storing or converting energy and oversized
renewable resources in autonomous ZEB compared to grid-
connected ZEB become a public discussion.

3. K. Voss, et.al. What is Really New
about Zero Energy
Homes?. 2008
 According to K. Voss while the energy systems used in off-grid
buildings have to be over-dimensioned, especial in term of
storage, in order to provide energy at all times [Goetzberger
1994], in grid-connected projects the goal is simply to have the
total amount of energy consumed in the building over the course
of year offset by the total amount produces. The connection to
the power grid therefore plays a decisive role as a sort of storage
battery for electricity, especially in Europe across seasons.
4. M. Noguchi, et.al. Net Zero Energy Homes
of the Future. 2008
 In this paper,of Noguchi and his team a net zero-energy home
(NZEH) is defined as a house that consumes as much energy as
it produces over a year and after few pages authors describe:
The BIPV/T system is an on-grid application accompanied with
an inverter for the AC/DC conversion. The system allows for
redirection of the locally generated electricity surpluses to the
grid.

et.al
Evaluation of the energy
performance for a nZEB
office Building under
climatic conditions. 2015
 Nicolae carried out a simulation work regarding the design
of a net zero energy office building with a mixed mode
ventilation system which assures the thermal comfort of
the occupants according to the ASHRAE 55/2010
Standard In India, with a rational consumption of energy
and a minimal environmental impact. The study relied on
the use of easily accessible building materials and
customary Air Conditioning (AC) equipment, in order to
meet the requirements.

8. The following are the objectives
 Analysis and design of residential building by ETABS.
 Analysis and design of residential building by using manual method.
 Comparison of results obtained from both methods.
 To use natural resources ( like solar, water and wind energy) more efficiently and reduce a
buildings negative impact on the environment.
 Implementation of zero-energy concepts.
