SAVE PAPER

•Use refill bottles for shampoo, soaps, cleaning products.•Buying products packed in materials which can be recycled.•Using refills instead of buying new pens.•Carrying own bag while shopping which will reduce plastic bags.•Prefer using fountain pens as they consume plastic only once and only ink is needed to refilled.

MINIMIZING PLASTIC

TRAPING SOLAR ENERGY

•128 kWh of solar radiation lands on one square foot horizontal surface over one year i.e. 460.8 mega joules.•5018111474.688*106 J of solar energy can be captured by land under VIT.•Amount too large to fulfill need of people here.•Heating water using solar water heaters.•Cooking food using solar cookers in mess.•Generating energy using solar panels.•Pool water can be heated using solar pool heaters.•Cover roofs areas with glass PV modules, which can be semi-transparent to provide shaded light.

RAIN WATER HARVESTING

•Average annual rainfall recorded in Chennai is 100 cm.•101.17* 106 liters of water can be saved•Need is about 365.1* 105 liters.•10% of VIT land is enough to fulfill need. •Terrace of the academic block can be used to store water during monsoon . •Tank with a size of 15*10*4 ft3 can store around 17,000 liters of water.• This water can be used in toilets and for watering plants.

•Using sensory shower heads: it will turn off showers when no one is standing under it, with the help of sensor.•Implementing sensory water taps in the cloth washing area as the maximum amount of water is wasted during washing clothes and the running taps just worsen the situation . •Checking toilet leaks.

•Using water meters.•Rinse vegetables etc instead of washing them under tap.

CONSERVING WATER

REDUCING POWER CONSUMPTION•Replace the CFLS and lights with LED lights. •No mercury is used in the manufacturing of LEDs. So they can be disposed of safely as compared to CFL’s.

•Reduce 3.4 buts’/hour.•Uniform dispersion of the light emitted by LEDs providing bright. •Materials can be coloured to complement the particular wavelength of the source.•Use automated lighting controls.•Implementing power switches for the bathrooms

•Skylight can be implemented on top of floor to provide natural light.•Cool roofs- to maintain lower roof temperatures.•Add window films to reflect light, so that the rooms can be kept cool during summers.•Paint front walls of classrooms with soft blue, sage green, purple color to increase concentration and have a calming effect.•Painting ceilings with white to reflect much of light.In gyms try an overall cream with a muted red, such as burgundy to avoid overstimulation.•Solar panels are present on terraces of buildings. For more efficiency, we can use mirrors on sides of each panel which will focus more light on the panels thereby increasing its efficiency.

IMPROVEMENTS IN BULIDINGS

TREATMENT OF WASTE•Sewage water should be treated and the phosphorous and nitrogen containing part can be used to spray over the grass planted.•It increases fertility of soil.•remaining can be treated to produce fertilizers and again used

•Install a drip irrigation system.•Apply mulches. They add organic matter, prevent evaporation, maintain even soil temperature, balance pH, and prevent weeds, chemical-free way to maintain a great garden.•Using native plant species in garden will lessen the water we need for irrigation and chemicals.
