A zero energy building (ZEB) generates more energy than it consumes, reducing greenhouse gas emissions and reliance on fuels. Key approaches to ZEB include passive solar design, energy simulation, and renewable energy generation methods such as solar cells and wind turbines. ZEB can be applied in various settings, offering advantages like reduced living expenses and environmental compatibility, although it faces challenges due to a lack of skilled designers and limited solar energy availability in certain areas.

3. WHAT IS ZERO ENERGY BUILDING ?
 A zero energy building is a building with zero net energy
consumption.
 Generates more energy than it consumers.
 Building contribute less overall greenhouse gases to the
atmosphere than a similar non energy building.
 Reduce carbon emissions and dependenace on fuels whis is the
ZERO NET-ENENRY CONSUPTION PRINCIPLE.

4. DESIGN AND CONSTRUCTION
 PASSIVE SOLAR BUILDING DESIGN :
Walls, floors and windows distribute heat during winter and reject
the solar heat during summer.
 BUILDING ENERGY SIMULATION :
Predicts the performance of ZNE building depending on the
energy usage before it is built.
 ENERGY SAVING FEATURES :
Include heating and cooling loads, insulation and ventilation
depending on the
climate

6.  To meet these energy needs, it produces or generates energy utilizing
several renewable sources such as solar cells provided at the site.
 Several micro-generation techniques of energy production are used which
may be listed as follows:
1. Wind turbines
2. Solar cells
3. Biogas
4. Small scale hydro-power

7. Design strategies:
 Envelope:
 Orientation/Massing
 Daylighting:
 HVAC and controls:
 Electrical lighting and controls:
 thermal mass::

9. ENERGY HARVEST
 Solar Cells
 Wind Turbiones
 Solar Thermal Collectors linked to Seasonal Thermal Energy Storage
 Solar Thermal Collectors – collects by absorbing sunlight.
 Seasonal Thermal Energy Storage (STES)- storage of heat or cold up to several months.

10. SOLAR ENERGY
1.Solar panels placed on the
rooftop absorbing as much of
the energy from the sunlight.
2.The energy can be used for
cooking, heating, etc………..

11. WIND ENERGY
In some extreme areas where wind energy is abutment and high, small windmills can
also be used to generate electricity for running small equiptment.

12. Thermal energy
1.It is used to maintain the ambient temperature of the building.
2.It can also be used for heating, cooling, etc….

13. Net Zero Energy Building Connected To
Grid
 Building connected to power grid can be termed as “Net Zero” if their energy
consumption is equal to their energy production over a year.

14. Various types of net-zero energy
buildings
 Net Zero Site Energy
 Net Zero Source Energy
 Net Zero Energy Costs
 Net Zero Emissions

15. How to achieve zero energy?
 A ZEB in only possible if three things happen:
 1. The goal is set early and the project team makes integrated
decision.
 2. Energy consumption is cut dramatically.
 3. An investment in on-site power generation is made(PV).

16. Zero Energy Building versus Green
Building
 Green Building is a building process depending on the environment and efficient
resources available.
 Green Building reduces negative impact on the environment.
 Zero Energy Building reduces more energy usage and greeanhouse gases emission.
 Zero energy building may not be considered Green in all areas.

17. Where can “ZERO ENERGY” concept be
adopted ?
 Residential Areas
 Commercial Buildings
 Industries
 New Construction and existing building.

18. Advantages
 1. Reduction in the net monthly expense of living
 2. Higher resale value
 3. Increased comfort in living
 4. Better reliability
 5. Economical even in the long run
 6. Isolation from the future energy rate increase
 7. Environmentally compatible
 8. Lower emission of carbon

19. Disadvantages
 Very few designers or builders have the necessary skills or experience to build ZEB.
 Solar Energy capture is only applicable for sun prone areas.
