INTRODUCTION
Energy crisis
Environmental issues

3. Zero energy building (ZEB)/
zero net energy (ZNE) building
Net energy consumption = 0
Carbon emissions = 0
3
Energy feed to grid = energy consumed

4. WHY ZEB?
Traditional buildings consumes 40%
of the total fossil energy
Buildings are responsible for 47% of national
energy consumption
ZEB design has become a high priority for
architects and multi-disciplinary researchers

5. HISTORY
• First documented attempts
– In the form of solar houses
MIT Solar House (1939) Vagn Korsgaard Zero Energy Home (1973)

ZEB & GREEN BUILDING
ZEB May Or May Not Be Considered "Green"
Environmentally Responsible
Resource Efficient
Green building - Throughout building's Life-cycle

8. 8
METHODOLOGY
Study the economic features of the building
Model the lighting and energy storage system
Achieve energy demands
Describe the passive strategies used in the house
Calculate the house heating and cooling loads
Study the weather and solar radiation data

ELECTRICITY PRODUCTION

15. 15
LIGHTING
To Decrease Destructive Environmental Effects
Minimize Energy Consumption
Uses Fiber Optics And LEDs
Can transmit daylight to different zones of home and is
joined to an illuminator to deliver light at night without
any dazing

ECONOMIC DISCUSSION
Aste (2012) - Economic feasibility of ZEB was discussed
High initial and maintenance cost, but zero running cost
Government subsidies

17. ADVANTAGES of ZEB
• Isolation for building owners from future energy price increases
• Increased comfort due to more-uniform interior temperatures
• Reduced Total cost of ownership due to improved energy efficiency
• Reduced total net monthly cost of living
• Improved reliability
• Minimized extra cost
• Higher Resale Value
17

18. DISADVANTAGES of ZEB
• Initial Costs can be higher
• Lack of skills or experience to build ZEBs
• ZEB may not reduce the required power plant
capacity.
• ZEB by definition do not mandate a minimum
heating and cooling performance level

CONCLUSION
ZEBs are more practical
Implemented in field economically
Substantial reduction in environmental issues
Eco-friendly buildings can be achieved
