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. To achieve this purpose, Renewable Energy Sources like Solar Energy, Wind Energy, Biogas Energy and Geo thermal energy have to be harnessed properly so that the energy borrowed from the Grid can be replenished by these sources. In this paper, an attempt has been made to compare the economic and environmental aspects of energy generated from these resources and to tell us which of the above mentioned non renewable energy resource is the best suited based on the parameters of economic and environmental feasibility.

  • Worst, focus on increasing energy supplies
    Better, focus on reducing demand
    Best, focus on reducing demand with durable assemblies that last centuries

  • Production of energy from renewable sources - this is fine, but the architecture itself can and should reduce the need for electricity.
    And these objects will soon be able to achieve this.
    First of all, due to a significant decline in the total area of the building envelopes, for a large complex of buildings, covered with a transparent roof . And secondly, through use of the clever modern life-support systems of the building.
    Architecture for ХХI century: Large-Span Translucent Buildings - http://blog.dp.ru/post/5274/ .
    The article proposes to consider the idea of creating a rational coatings for large spans ( including translucent coverings) and is about how we can bring a bit useful Green of variety for monotonous Architecture our towns - to build a large and comfortable public spaces and to expand the comfortable environment for life of people in the big city.
    Large-span buildings and structures can be made of the shape and size desired, depending on the combination of features and mutual alignment of the cable and supporting structures.

Zero energy buildings economical and environmental aspects

  1. 1. IEI ppt (MD ASIF AKBARI) MD ASIF AKBARI B.Tech (Civil), KIIT Univ. Assistant Engineer Ashiana Housing LTD +91-9521930692 (Whatsapp) akbariasif12@gmail.com
  2. 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. IEI ppt (asif,apurva,archana,arpita)
  3. 3. Buildings are the Largest Energy Consumer IEI ppt (asif,apurva,archana,arpita)
  4. 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. IEI ppt (asif,apurva,archana,arpita) What is a Zero Energy Building?
  5. 5. IEI ppt (asif,apurva,archana,arpita)
  6. 6. Bayer Material Science building in Greater Noida IEI ppt (asif,apurva,archana,arpita)
  7. 7. Components of Zero Energy Buildings Building's orientation on the site, window and door placement. Wind Effect Stack Effect Combustion and Ventilation IEI ppt (asif,apurva,archana,arpita)
  8. 8. Plantations On The Roof IEI ppt (asif,apurva,archana,arpita)
  9. 9. Insulation on walls and using Light colored roof IEI ppt (asif,apurva,archana,arpita)
  10. 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. IEI ppt (asif,apurva,archana,arpita)
  11. 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. IEI ppt (asif,apurva,archana,arpita)
  12. 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. IEI ppt (asif,apurva,archana,arpita)
  13. 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. IEI ppt (asif,apurva,archana,arpita)
  14. 14. Comparison Economical comparison shows that wind energy is most economical amongst all renewable resources mentioned in the graph. IEI ppt (asif,apurva,archana,arpita)
  15. 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.
