Baroda gets a taste of ZED insights

Picture 156President – ZED Communities, B.S. Harikrishna made a presentation in late November in Baroda to a very discerning audience of architects, urban planners, and students of engineering and architecture. It was at an IGBC event in the once royal city of Vadodara.

He received a standing ovation. At the end of his presentation, Karan Grover, a well-known architect in practice from the town, who is also the chapter chairman for the city, picked up the mike in a moment of enthusiasm at the deep impact that the presentation had made and said, “I make a commitment to get Harikrishna to meet Modi, the Chief Minister.
Let me see how the government can help his company secure a land where they can demonstrate these ZED approaches to energy, water, and waste.” We haven’t yet heard from Karan or the Gujarat Govt. But let’s hope someday there’ll be the opportunity to push such frontiers.

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.

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.

Zed posts – The weekly environmental beat


• On BMW smart energy strategies

BMW recently convened a group of transportation, electric vehicle (EV) and energy thought leaders in Silicon Valley to participate in a dialogue with their senior executives about sustainability, energy and mobility services.

greenbiz.com: Christine Hertzog – how-bmw-driving-smart-energy-strategies

BMW’s guiding view is that sustainability along the entire value chain is inseparable from their corporate self-image. The company has been systematically reducing energy use in facilities through energy-efficient materials, products, and processes; and in vehicles through use of regenerative energy technologies.

1• On green burglary

Is it ok for an unauthorized person to pick up your recyclables? Do you give your recyclables to scavengers when they come begging, or do you put them off?

greencrusador.com: Author – what-is-green-burglary-what-can-we-do-about-it/

Residential neighborhoods have become targets for recyclables by “Green Burglars” when placed beside the house or at curb side. Once the recyclables are placed in a recycle container provided by a designated recycle collector, the contents becomes the property of the designated recycle collector.

zed 1• On Carbon Barometer

A quick look at the aims and benefits of the Bombay Stock Exchange Carbonex.

Times of India: Ahona Ghosh – bse-carbonex

The index is supported by the British high commission and the Carbon Disclosure Project (CDP), a UK-based non-profit organisation is the data partner for BSE. It includes all constituents of a BSE Benchmark Index, which is currently the BSE 100.

light• On Behavioural Science increasing Energy Efficiency

How consumer behaviour to different sales tactics can provide an insight on effective communication on the benefits of Energy Efficiency (EE) and raise awareness to attract more customers.

greenconduct.com: Sam Shrank – behavioral-science-can-increase-energy-efficiency-adoption/

For all the surveys demonstrating consumers’ stated interest in reducing energy consumption and spend, EE is rarely top of mind. Utilities struggle to get consumers to pay attention. If the customer won’t come to them, perhaps it is time for utilities to go to their customers. By combining EE measures with offerings that have higher intrinsic appeal and shifting marketing focus from saving energy to the benefits of the other measure, utilizing a concept known as goal substitution, utilities can attract more customers.

zed 2• On using algae for power and shade

Germany to use living algae for power and shade in a sustainable building, which would also feature the world’s first bio-reactor façade.

ecomagination.com: Ysabel Yates – zero-energy-building-uses-living-algae-for-power-and-shade

The bioreactor facade is made up of glass panels that act like giant Petri dishes to grow the algae. The algae can then power the building by both capturing solar thermal heat and creating biomass that is harvested for energy.

Wind Energy

Can you imagine power coming into your city buildings from both wind and solar energy? Now you can, with the ZED-Winsol, which is a wind and solar hybrid system tied into external power grid. We augment the grid with a solar panel array of 2kW and wind mast of just a kW. The power inverter connected to all 3 sources, detects the source and optimizes the load coming in from solar or wind. Every time a power-intensive appliance like a refrigerator or a grinder is used, it’s tied into the grid. So the impact load is fed from the grid, saving over 70% grid power. The wind mast designed on a Helix platform, helps to pick both vertical and horizontal directional energy and is rated to work at as little as 2.5 meters a second.
The wind factor alternates with the solar power in most evenings generating power through the night and augmenting the grid when needed. In case the grid fails, the safety feature called ‘anti-islanding’ helps the power to stay and it is ‘piped’ into a battery system for storage. This only gets better with ZED using only two batteries instead of the 15 used by most systems. These batteries are 12 volts 150 amp and can be augmented with a separate battery bank to store more power. Want to know more? Email us at zed@zed.in

We’d be better off not planting trees-II: There’s more to it…

English: The Woodside Hotel and the big tree

Image via Wikipedia

I took a factor of 2.5 to cover centralized air-conditioning, the pumps, and the array of cooking and other appliances that help a 5-star hotel serve its customers. That totted up to about 4.5 million units a year. Not much as money goes… about Rs 30 lacs a month, or Rs 3.6 crore a year. I may be wrong on my hazard of these estimates, for I have gone on a certain premise of use of power in the hotel without having had the opportunity to do what one calls a ‘load analysis’.

Power & water crisis-I: Get your home in order, will you?

Wind turbines (Vendsyssel, Denmark, 2004)

Image via Wikipedia

This is a four-part series titled ‘Get your home in order, will you?’ If we stopped fretting over what the government has not done on energy and water, and sort some things at home, more than half the solution will spring before us.

Part 1

The power scene at home

Have you looked at your energy bill recently? What is the amount you pay every month for power? For water? Have you asked yourself what the break up of power used in your house is? Do you realize how much of the power bill is coming out of use of your geysers? How much is consumed by fans, your lighting, your TV set, the grinder and mixer in the kitchen, or worse that electric oven that your mother gifted you on your last birthday? How much of the power is used in your kitchen by the refrigerator, the heating plate, and such other appliances that didn’t even exist 30 years ago? Continue reading
