  • Just not seeing the smoke doesn’t mean that there is no pollutionIndia produces electricity majorly from coal and the availability of reserves say that for atleast next 50 years India will be using coal
  • Human body analogous to heat producing machine which has to keep on emitting heat in order to feel comfortable, Either the air can be conditioned or the air flow can be increased, Since ventilation analysis of entire building is not feasible, ventilation analysis of Departmental office is done in the project

    1. 1. GREEN<br />BUILDINGS<br /><ul><li>BY:</li></ul>LOKESH ZOPE – 0715048<br /><ul><li>PROJECT GUIDE: </li></ul>PROF. V. S. NARWANE<br />
    2. 2. WHY DO WE NEED TO THINK ABOUT BUILDINGS?<br /><ul><li>Buildings consume almost one-third of the total energy produced
    3. 3. Problems of energy crisis are impending
    4. 4. Buildings are the places where humans spend </li></ul> their maximum time <br /><ul><li> A conducive environment to work is always</li></ul> beneficial for efficient work output<br />
    5. 5. RESOURCE <br />OPTIMIZATION<br />HUMAN <br />COMFORT<br />
    6. 6. SOLAR GRID-TIE CONNECTION<br />SUN<br />
    7. 7. HOW TO SIZE?<br />SYSTEM REQUIREMENT<br />INVESTMENT<br />

    11. 11. DESIGN PROCEDURE<br />
    12. 12. 1. SYSTEM SIZING<br />Pac = Power required (KWh/yr) = 620000 =340KW<br /> Hours/day of 1Sun x 365 days/yr 5 x 365<br />Pdcstc = Pac = 340/0.97 = 350KW<br /> Conversion Efficiency<br />
    13. 13. 2. ORIENTATION<br />N<br />Tilt angle = 90 – βN<br />Where, βN= 90° - L + δ<br /> δ = 23.45 sin[(360/365)(n-81)]<br />

    19. 19. 4. ECONOMICS<br />Total investment = Cost of inverter + cost of panels + cost of connectors + cost of module maintenance systems + installation charges<br /> <br />Cost of inverters: $4000 x 35 = Rs. 6.5 crore<br />Cost of solar photovoltaic panels: Rs.23700 x 1155 = Rs. 2.7 crore<br /> <br />Total cost: Rs. 9.2 crore<br />Approximately total investment: Rs. 10 Crore<br />The total cost spent in buying power per year: Rs. 72,00,000<br /> <br />Total money saved:<br /> <br />First 5 years: full efficiency (i.e. the system will provide entire power)<br /> Rs. 72,00,000 x 5 = Rs. 3.6 Crore<br /> <br />Next 7 years: 90% efficiency <br /> Rs.72,00,000 x 0.9 x 7 = Rs. 4.536 Crore<br /> <br />Next 13 years: 80% efficiency<br /> Rs. 72,00,000 x 0.8 x 13 = Rs. 7.488 Crore<br /> <br />(The company of the panels provide the product guarantee of above efficiencies)<br />Total saving for 25 years after installation: Rs. 15.622 Crore<br /> Inflation rate of<br /> cost of power<br /> Investment gains<br />
