What is a Sustainable Green Building?

sustainable-green-building

Sustainable Green Building is a concept that has gained popularity at a global level in the past few years. This is due to the fact that for a green building, starting from its construction it is ensured that waste is minimised at every level. The materials used are not only of superior quality but also eco-friendly. According to the experts, this not only minimises our carbon footprint but also results in lower costs in the long run. Hence, we can say that a green building is constructed in such a way that they reduce their overall impact on natural environment and as a result on the human health by:

1. Using the energy, water and other resources judiciously and efficiently.
2. Protecting the environment and improving human health conditions.
3. Effectively minimizing the waste production, pollution and environment deterioration. 4. Using natural resources like natural light wherever possible to effectively manage the use of energy.

In order to achieve the minimum energy consumption level, following features are incorporated in a green building which makes them earth friendly: 

1) The walls are designed to keep out the moisture and humidity in the outside air which makes the building naturally cooler. This reduces the use of air conditioners.

2) Low Solar Gain. Solar gain is the increase in temperature resulted from the solar radiation. With low solar gains, the building remains much cooler which again reduces the need for air-conditioners.

3) Using water efficient faucets ensures that less amount of water is utilised to perform the same function as compared to their traditional counterparts.

4) Rainwater Harvesting systems are installed to catch the natural rain water to  cater to the building’s water needs.

5) Wastewater treatment plants for minimising the waste water expulsion from the building and effective water management with water recycling.

6) Installing hydroponics system to increase the green belt while reusing the water through utilising treated greywater.

7) Creating waste management plants on the site such as compost pits to utilise the building’s biodegradable waste for fertilizers.

8) Installing clean energy sources such as solar panels, solar water heaters etc for electrification.

The green building concept has a vast benefit cover can be effectively employed for various sites, some of which are: 

1. Residential buildings
2. Office Complexes
3. Institutional buildings such as schools, colleges etc
4. Retail buildings
5. Hotels
6. Hospitals
7. Government Buildings

The concept of green building, however new, aims at using natural building materials during  not only construction, but also adopts other methods, such as rainwater harvesting for its water needs, solar energy for the electrification, waste management, etc. Hence making the making green building self sufficient when it comes to the energy requirement. The efficient usage of natural resources and their further recycling, ensures sustainability in the long run.

What are Wastewater Treatment Landscapes?

What are Wastewater Treatment Landscapes

Wastewater Treatment Landscapes or Sewage Treatment Plants Landscapes are the landscape structures which are build in such a way so as to efficiently use the wastewater from the treatment plants while obscuring the Sewage Treatment Plant from plain site and at the same time adding a green space to the complex.

Wastewater management is need of the hour, as with the ever-rising global population, we are already facing a huge water crisis. The most important step in fighting this crisis is the efficient management of water supply. The water once used in bathroom sinks, laundry or shower heads is considered as grey water and it contains organic material that is good for plants. This runoff water can be used for gardening purposes which not only reduces the total freshwater demand but also boosts the plant growth.

In the last decade there has been huge advancement when it comes to environmental engineering research on decentralized, biological remediation of wastewater. Wastewater Treatment Plants or Sewage Treatment Plants are specially designed for the  purpose of regulating hydrologic flows in surface drainage systems. They are spatially and strategically distributed in the landscape and can treat wastewater generated from institutional land uses, residential and corporate complexes.

Once we come to a conclusion that adding a wastewater treatment plant is vital for cost purposes as well as for effective water management, the next question that comes to mind is how we can beautify it. With careful planning, sewage treatment plant landscapes can be designed that are not only pleasing to the senses and but also kind to the environment. These following factors should always be kept in mind while creating a sewage treatment plant landscapes:

Plan

Just as before constructing a building, lots of thought is given in preparing its plan, similarly it is very important that a plan is created for the landscape so as to take into account the drainage between the Wastewater Treatment System, the placement of turfs, vegetation and its placement, landscape accessories etc

Vegetation

Choosing the right kind of vegetation is very important while creating a Sewage Treatment Plants as some plants require more water than the others and also on what kind of vegetation is suitable for the combination of nutrients present in the treated water.

Soil

The kind of soil to be added to the landscape structure also depends on the plantation and the nutrients already present in the treated water.

Maintenance is key factor for any system to be a success, similarly the Water Treatment plant landscape needs periodical maintenance, like checking the nutrients in the water from time to time, cleaning the drainage channels etc.

Reduce, reuse and recycle- what does it mean in terms of water

Reduce, reuse and recycle- what does it mean in terms of water

Most of the sustainable or green movements focus on three R’s. That is reduce, reuse and recycle. In general terms, it means to minimize the wastage, reuse the available resources to the maximum and recycle the waste. These three R’s are equally important in term of water. In today’s scenario, where water is becoming the global concern and the world sees the drought in the near future. In fact some places are facing the drought situations, it is very important for us to follow the path of three R’s in the wellbeing of our planet and our generations. Following in this post we will understand each R in term and its importance and how we can achieve the same.

Reduce:

Reduce

This means that we should reduce the usage to the minimum. Well, we cannot stop the necessary use of water but the wastage of the same can be eliminated. We tend to waste water in many ways: may be in over flushing, long hours of the bath, running it down the drains while filling buckets or simply leaving the taps open while we are busy doing some other activity. These are some very generic scenarios which we do in our day today lives. This wastage can be easily eliminated. The water is available in abundance on planet but the irony is that only 0.3% of the water is available for use. Now, if we waste this water and thus rendering it unusable then we are simply pushing ourselves towards the drought situations. The reduction in wastage is the mantra for sustainability.

Reuse:

Reuse

Another mantra in the three R’s is reuse. This term is very interesting. So far we have tried to reuse our waste to make some good stuff out of them like bottles converted into lamp shades or vases, or newspapers converted into carry bags and so on. But here we are talking about reusing water. How can we reuse water? This may hit our minds because once used, it goes down the drains. Here lies the key area. Instead of letting the used water go down the drains we can direct them for reuse. The used water from bath, laundry or sinks is known as greywater. This can be treated at different levels for removing chemicals from them and can be used again. The water from the sink or bath can be used for mopping, car washing, irrigation of plants, and other non-potable activities. This will decrease the pressure from the fresh water that is used in these activities.

Recycle:

Recycle

This is equally important for the survival of the planet. To give back nature what we take from it. The simple rule is give and take. Nature gives us what we need for our survival. It is equally important for us to give it back what it needs. The rainwater which is the source of fresh water is drained down the sewer lines making it unusable. This rainwater can be harvested to balance the underground tables to combat drought situations. The farms and gardens can be irrigated from the same and it can also be used for non-potable activities of our daily routines. It is true that if everyone follows that path of three R’s in every aspect that definitely we can overcome the critical situations which the world is facing or will face in the future and can also give our generations that path of sustainability.

NEW DELHI

The dry climes of Jaipur haven’t stopped Delhi Metro from trying to build a city forest. Metro will soon start working on its second phase and along with the construction of the line, the agency is developing a “Metro forest”.

“Jaipur Metro has developed a ‘Metro forest’ in 5 hectares of forest land and planted about 3,000 trees. In addition, some trees which had to be shifted from the site have been transplanted here,” said Delhi Metro Rail Corporation (DMRC) spokesman Anuj Dayal.

He added, “DMRC is the general consultant for the second phase, while the actual construction is being done by CEC, a Taiwanese company”. Metro is also introducing a rainwater harvesting system where its viaduct will act as catchment for rainwater.

“Also, a 100 KWP solar power plant has been constructed at the Mansarovar depot, which will produce an energy saving of Rs 1 lakh per month,” said Dayal. Along the 9km elevated route, 12,800 LED lights have been provided under the mission, ‘Save Electricity Build Nation’, he added.
