ECOLOGICAL FOOTPRINT The Ecological Footprint definition is simply

ECOLOGICAL FOOTPRINT The Ecological Footprint definition is simply a way to measure how much we use and consume, in relation to our environment’s capacity to provide and support our needs. It calculates our impact to our environment.

DETERMINING FOOTPRINT The calculation takes into account items such as transportation habits, home size, heating/cooling sources, food consumption, energy usage, water sources, recycling and habits. Essentially, calculating your footprint means analyzing your lifestyle.

The Ecological Footprint is the only metric that measures how much nature we have and how much nature we use. The Footprint helps: COUNTRIES improve sustainability and well-being LOCAL LEADERS optimize public project investments INDIVIDUALS understand their impact on the planet

It measures the requirements for productive areas (croplands, grazing lands for animal products, forested areas to produce wood products, marine areas for fisheries, built-up land for housing and infrastructure, and forested land needed to absorb carbon dioxide emissions from energy consumption).

HYPOTHESIS RESIDENTIAL BUILDING This study investigates the ecological footprint of a residential building as an indicator of environmental degradation. Six blocks were examined. Four of them having eight apartments in each while the rest two blocks have three apartment units in each.

ELECTRICITY Electricity consumption of a typical unit (Block A & B) : Average consumption of a day: 7400 W Summer : 7400 x 8 x 30 = 1776, 000 W Average consumption of a day: 4400 W Winter : 4400 x 4 x 30 = 528, 000 1776, 000 + 528, 000 = 2, 304, 000 W No. of Apts : 6 Total consumption of two blocks per year : 2, 304, 000 x 6 = 13, 824, 000 W

ELECTRICITY CONSUMPTION OF A TYPICAL UNIT (BLOCK C-F): Average consumption on daily basis : 5, 500 W Summer : 5, 500 x 8 x 30 = 1, 320, 000 W Average consumption on daily basis : 2, 500 W Winter : 2, 500 x 4 x 30 = 300, 000 W 1, 320, 000 + 300, 000 = 1, 620, 000 W No. of Apts : 8 (units) x 4(blocks) = 32 Total consumption of four blocks per year : 1, 620, 000 x 32 = 51, 840, 000 W

WATER FOOTPRINT The water footprint has three components: green, blue and grey. Together, these components provide a comprehensive picture of water use by delineating the source of water consumed.

It is possible to use the water footprint to measure the amount of water required to produce all the goods and services consumed by the individual or community, a nation or all of humanity. This also includes the direct water footprint, which is the water used directly by the individual(s) and the indirect water footprint – the summation of the water footprints of all the products consumed.

DIRECT AND INDIRECT WATER USE The water footprint looks at both direct and indirect water use of a process, product, company or sector and includes water consumption and pollution throughout the full production cycle from the supply chain to the end-user.

WATER SUPPLY A part of ecological footprint can be reduced by being conscious of the water usage. Each time you take a 15 minute shower you are using 90 gallons of water. Each time you flush a toilet you use 5 gallons of water. Each day more than 1 billion people walk 3 hours to collect water

WATER CALCULATION Average usage of water person per day : 40 gallons. Water usage person annually : 40 x 30 x 12 = 14, 400 gallons No Of residents : 122 Total usage of residents annually : 14, 400 x 122 = 1, 756, 800 gallons.

GAS FOOTPRINT The study of the carbon footprint of natural gas in order to assess its impact on climatic processes has shown that the carbon footprint of natural gas at the stages of production, transportation, storage, and distribution amounts to not more than 17 kg CO 2. The comparative study has revealed that its value is less than that of gasoline, kerosene, and diesel fuel.

CALCULATION The average monthly consumption per house in each block is 88 CMs while the lowest average value of every house in residential complex is 49 CMs.

WASTE FOOTPRINT A child born in a wealthy country is likely to consume, waste, and pollute more in his lifetime than 50 children born in developing nations. Our energyburning lifestyles are pushing our planet to the point of no return. " George Carey, former Archbishop of Canterbury

WASTE CALCULATION We measured our waste impact by quantifying material that has not been reused, recycled or recovered. On an average each house in residential complex dispatches 5 kgs of waste per day consisting higher amount of plastic (snack packets, polythene, bottles etc).

SOLUTIONS FOR THE REDUCTION OF CARBON FOOTPRINT WATER USAGE: Water-oriented strategies significantly reduce energy use and greenhouse gas emissions. Leakage of pipe lines, unused water flowing from tanks can be counted as the major causes of water footprint.

WATER SOLUTION The problem can be solved by specifying plumbing equipment that prevents leaks-or "real water losses"the most troubling element of what water efficiency experts call "non-revenue water. “ Installing efficient fixtures and appliances can reduce water usage. Specifying high-efficiency toilets with reduced average flush volumes compared to conventional toilets.

ROOF COOLING We can also tweak a little more energy efficiency by choosing roofing materials with the appropriate solar reflectance and thermal emittance values tuned for the location and occupancy of the building. Color choice affects solar reflectivity strongly and choosing the right color for the climate can reduce energy use as much as 2 to 3 percent.

POWER SAVING Within the last couple of years, LEDs have become cheap and effective. Many have energy-guzzling halogen lights in their house. People have them in kitchens and bathrooms – it makes good financial and carbon sense to replace as many as possible with their LED equivalents. Not only will CO 2 footprint fall, but because LEDs are so efficient, it will also help in reducing the need for national grids to turn on the most expensive and polluting power stations at peak demand times.
