  1. Human Impact on the environment

  2. When you look at the history of humanity it's basically a relationship between the two most complicated systems on Earth :Human society and nature. • Now , We are causing the devastation to our very foundation of our life system that has given us birth. • We should come out of the illusion that people are separate from nature.

  3. Pollution • Since the industrial revolution, society has had a tendency to assume that the environment can absorb any amount of pollution. • Many of the most disastrous incidents of pollution involve industrial chemicals that are toxic or carcinogenic Pollution from thermal power plant

  4. Pollution and Acid rain • Rain and snow carry the sulfuric acid formed when sulfur reacts with water back to the surface in the form of acid rain. • It causes loss of species diversity in bodies of water. • Destruction of trees and organisms due to low pH levels in ground water. • Extinction of a lot of species. Trees killed due to acid rains

  5. Depletion of Ozone Layer • Chlorofluorocarbons (CFCs) are a class of chemicals involved in ozone destruction. • Coolant in refrigerators and air conditioners propellant in aerosol dispensers release CFCs. • Ozone depletion will cause and increase in the number of people who develop skin cancer and cataract. Ozone layer

  6. Global Warming • Carbon dioxide in the atmosphere influences global temperatures.Global warming during Earth's current interglacial warmperiod has greatly altered our environment and the distribution and diversity of all life. • Global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) between the start and the end of the 20th century • Broader effects are expected to include glacial retreat, arctic shrinkage,  including long-term shrinkage of  Greenland ice sheet, and worldwide sera level rise due to global warming.

  7. Extinction of Species • Over the last 50 years, about half the world’s rain forests have been destroyed for pasture and farmland or for timber • Rain forests have the highest species diversity in Earth • It is estimated that at least 1/5 of the world’s animals and plants will become extinct over the next 50 years

  8. Non-replaceable Resources • Fossil fuels: Fossil fuels like coal, natural gas and petroleum products once used are not replaceable and will add global warming gasses in to the environment. • Loss of top soil: by repeatedly turning over soil to eliminate weeds, by allowing animals to overgraze ranges and pastures, and by practicing poor land management we permit the wind and rain to remove more and more • Pollution and depletion of ground water: Water seeps into aquifers at too slow a rate to replace the large amount of water being withdrawn for unnecessary use (watering lawns, washing cars, and running fountains)

  9. Examples of Disastrous Events • In the early 1970s, Lake Erie was so polluted from large amounts of industrial chemicals that few fish could survive there • The Exxon Valdez ran aground on the Alaska coast in 1989, spilling 11 million gallons of oil and killing thousands of marine animals. Even today the evidence of damage to local wildlife continues to mount • UN estimates by the middle of the century there may be 150 million environmental refugees at any given time from climate change. Katrina

  10. Natural calamities

  11. The 5 components of solving any environmental problem • Assessment • Risk analysis • Public education • Political action • Follow-through

  12. Assessment • The gathering of information • Data collection • Performing experiments • Make predictions

  13. Risk Analysis • Use the information from assessment to predict the consequences of environmental intervention • Evaluate the potential to solve the problem as well as any adverse effects the plan might create

  14. Public Education • Inform the public • Explain the problem in understandable terms • Present alternative actions • Explain probable costs and results

  15. Political Action • The public, through its elected officials, selects and implements a course of action. • Exercise your right to vote. • Write to elected officials. • Support special interest groups.

  16. Global Warming Solutions • Reducing the amount of gas released in the atmosphere : • energy efficiency • renewable energy • vehicle technology solutions • Increase the efficiency of photosynthesis

  17. Why aren't we responding to climate change? • First and foremost : economy >>The greatest weapon of mass destruction is corporate economic globalization. >>People think that, to implement eco-friendly measures is expensive. • Lack of awareness >>Many people still don’t know what is green house effect. >>what extent it is damging our eco-system

  18. Fundamental opportunity cost of economic growth • As the economy grows, it displaces, it encroaches upon the biosphere, and this is a fundamental cost • What would it cost us to take carbon dioxide out of the air and put oxygen back in it, which all the green things do for us for nothing. • What would it cost to pollinating all of the flowering plants. • In our modern globalized world growth continues to be the focus of many corporations and governments who deplete our environment for economic gain.

  19. What BLAZEcan offer? • Blaze considered both environment and economy to design products which keep balance between both of them. • One of its kind is BLAZE occupancy based lighting system. • On an average 30% of the energy on lighting can saved by implementing occupancy based lighting. • There are other indirect benefits from occupancy based lighting. Refer to annexure 1

  20. How occupancy based lighting works (example) Provide light when and where it is required – an egress path for late night workers eliminates unnecessary energy usage after hours.

  21. Estimates average saving potential for different space types using occupancy sensors • Private office 13–50% • Conference room 22–65% • Classroom 40–46% • Restrooms 30–90% • Corridors 30–80% • Store areas (including warehouses) 45–80%

  22. Detection pattern of Occupancy sensors

  23. Features Blaze Occupancy sensors • All occupancy detection sensors feature advanced robust platform along with Day Light Harvesting sensor inbuilt. • Easy installation with out retrofit or reconstruction • On-board management selectable setting for maximum control without requiring advanced technical knowledge • Multiple rooms, HVAC and balcony doors easily accommodated with no additional wiring required • Occupancy detection only requires single occupant movement. Wide range of cost effective and reliable occupancy sensor are available with BLAZE

  24. ROI - Conclusions • Average ROI for 30% saving: 18-24 months Note: Here we have assumed that the Lighting fixtures are ON 12 -14 hours per day and there is a saving of only 30% [averaged considering all the areas in a typical corporate setup] of the energy for Lighting through Occupancy sensors. This also includes savings through indirect savings.

  25. What it contributes to environment • Suppose if you going to save minimum of10000KWh per month for you whole building see how it will help environment 10000 90 90 7.5 450 37.5 Note: Reference for this calculation:
