BCIL raises Rs 900 million to fuel growth

Rupees-symbolIn a major breakthrough, BCIL has signed a deal closure for Rs 900 million from a large Bombay-based funding institution. The transaction is a combination of funding in the two premium BCIL projects exceeding over 1 million sft between Bangalore and Chennai.

This is the first major fund that the green major has accepted after establishing itself as an undisputed leader in energy-efficient buildings.

ZedEarth in Bangalore is a half- million sft. development that cuts fresh water demand by 70 per cent, uses no borewells and cuts energy demand also by 60 per cent with a combination of demand-side and innovative supply-side solutions.

ZedRia in Chennai offers over 600,000 sft of similar zero energy developed homes with no dependence on external water supply and sewerage board.

Energy and water harvesting and urban agriculture are unique to each of these zero energy developments. Both projects are under way and will offer a total of nearly 1,000 homes over the next 1 to 3 years.

Are your plants getting the right amount of water?

watering-can-old-manTending to a garden is a liberating experience and lets you bring out the eco-philic side of you. Although looking after a garden is not rocket science, care must be given to all aspects to ensure your plants look healthy and fresh. One such aspect that is generally overlooked by most of us is watering the plants. Although it appears to be a simple activity, it is in fact one of the most misinterpreted, often with disastrous consequences for the plant. When understood and carried out properly, it is capable of significantly influencing the relationship with the garden.

So let’s start at the very beginning. While we say “we’re watering the plants”, we don’t water plants, we actually water the soil.

Yes, that’s right. Plants take in their required amount of water from the soil so watering the soil around the root zone (away from the stem) is most beneficial to the soil micro-organisms, and therefore the plant.

Equally critical is knowing that plants need moist soil rather than wet or submerged soil. Moist soil enables the water to break down necessary components in the soil into a small enough size to be absorbed through the plant’s root system. Over watering can lead to loss of nutrients and minerals and also decrease aeration.

Plants should be watered early in the morning and not late in the evening. Plant diseases are known to spread in wet, dark conditions and when we water in the late evening, water tends to stay on the leaves, making the plant more susceptible to catch mildew (a fungal disease). In daytime, if water does get on the leaves, it has a chance to dry out in the sunlight. Also, plants need water mainly during daylight to produce food, so watering early morning would ensure that they are able to carry out their activity.

Gardens are completely dependent on our watering and so it needs to be planned and regular. Erratic watering stresses the plants. Allowing the soil to dry out completely between watering is not a good idea and works only for specific plants. Most plants require consistently moist soil conditions.

How do you water plants?

For an urban home garden, there are several ways to water from the simple bucket and mug or rose-can (can with a shower-head nozzle) to the more planned drip irrigation mechanism.

Adopt a method that is best suited for you and one that does not waste water. As far as possible, try to harvest rainwater. Reuse grey water – i.e. water used for washing clothes or vessels for use in the garden. But remember this is only if we avoid synthetic detergents and use natural alternatives or other powders.

Mulched soil has greater water retention capacity and also provides nutrients. It is best suited for a garden. If you have a rooftop garden, ensure windbreaks to prevent uprooting of plants.

Paying attention to the health of the soil is the most important aspect of a plant’s health. Ensuring a well-proportioned mix of sand, red earth, compost and soil-building material (like cocopeat) is essential to make the soil loose, porous and to increase its water retention capacity.

The needs of each plant are different and so plan your gardening activity accordingly taking care of each plant to have a healthy and lively garden.

Green Tech and Sustainable methods

11Your tap water is cleaner than you think

Cities waste water for luxury! Most institutions and households in the cities are supplied with soft water. They blindly install Reverse Osmosis (RO) systems, which waste more water than they purify- almost in the ration of 60:40.

All housing and office buildings have single pipe connections,which supply drinking water even for flushing toilets. Not every one uses the modern commode which has dual mode of flushing. At one flush, more than 10 liters of precious drinking water is lost! At ZED we use Low-flow fixtures that curtail the net water demand by as much as 30,000 liters a year of fresh water saved. Grey and black water segregation at source and treatment is also done separately.

1Standby mode is like a leaky tap

2700 million units of electricity is lost annually through appliances in standby mode. Put off your TV sets,set-top boxes,and personal computers. Rural poor has very small standby consumption,followed by urban slums. Urban middle class has the highest standby consumption.

IMG_0319Recycling wasted electricity from lifts

Just like metals and plastics,energy can also be recycled. Elevators and escalators fitted with regenerative drive technology allow the recovery of the energy used to move them up and down. This energy is then converted for use elsewhere in the building;in elevators,as much as 50% of the total energy used can be recovered this way.
