Why Green?
1. Esencia is the pilot project adopted for Green Rating by GRIHA (Green Rating for Integrated Habitat Assessment) for integrated townships.
2. STP (Sewage Treatment Plant) for re-use of Waste water in horticulture, Flushing etc.
- The sewerage system will be based on conventional water carriage system, in which soil and domestic waste generated by individual buildings/toilets will be collected into a collection chamber, through soil and waste piping system.
- The collection chamber from all units shall be connected to the nearest manhole on the external sewer line planned along the periphery of the building and as per site conditions.
- It is proposed that the domestic Sewage Treatment Plant for recycling so that the treated effluent can be recycled for Toilet flushing, Landscaping. Surplus treated effluent can be disposed in Municipal sewer line as per local site conditions.
3. Water conservation using Rain Water Harvesting and treatment and re-use of rain Water.
- Due to urbanization of the land and sharp growth in population and thus increase in water demand for various uses, the fresh water is becoming scarce in most regions of the area. In certain areas due to almost total dependency on the underground water, the wells and bore wells are getting deeper and deeper. Also due to increase in paved surface/roof areas, the amount of natural/percolation of rainfall is reducing very drastically. Therefore, it has become very necessary to harvest the rain water as maximum as possible.
Out of the various techniques adopted in India, and approved of by the Central Ground Water Authority, the following are the three main classes of rainwater harvesting systems:
a) System that collect direct roof runoff for storage and then reusing for various purposes.
b) Systems that use in-field or adjoining surface catchments to collect run-off and then impounded for irrigation, horticultural, recreational & domestic purposes, after treatment.
c) Systems that utilize the rainwater run-off from various surfaces including Terrace and Roads and green areas etc. for re-charging of the underground aquifer, through various measures.
- In this system, the catchments from roof/terrace areas are further segregated for direct recharging of aquifer through filter media.
- The Catchments from surfaces of road/paved/park/lawns etc. is segregated and then taken to underground, through de sitting chamber/oil and grease separator etc.
4. Treated Bore Well Water as Water Supply to every plot.
The Proposed water supply scheme to cater to the public and domestic water requirement of the project consists of sourcing water from public supply into a common collection facility known as Raw Water Sump. The Raw Water Sump will be constructed in RCC. The Water from this sump shall be treated in the water treatment plant consisting of filtration, softening, and chlorination units, depends upon the quality of water. The treated water shall be stored in treated domestic water sump. The water from this sump will be pumped to overhead tank and from there water will be supplied thru gravity.
5. Solar-based hot water systems.
Minimum 30% hot water requirement of all buildings built by Ansal will be provided thru solar based hot water system.
6. Solar-based Street Lighting.
Minimum 30% of street lights used in the development will be of solar based which may also help to earn carbon credits under Clean Development Mechanism.
7. Green and Eco-friendly Street Furniture.
All street furniture's will be made out of recyclable material, materials having low embodied energy, non hazards material.
8. Garbage and Solid Waste Collection, Garbage and Sorting Bins through out the township.
The wastes that are generated from the day to day activities which are in solid form are categorized as solid wastes. Solid wastes of different types include dry refuse of house and street sweepings, broken furniture, crockery, kitchen wastes, waste automobile parts, discarded parts of electronic wastes & other day to day house hold wastes.
The solid waste generated from the proposed development is in the form of organic and inorganic form. The solid wastes generated are segregated at its point of generation, collected and stored at a common designated place and Organic solid waste will be treated in an organic converter and the product will used as manure for Landscape or used as fuel.
9. Proper Diversion of Wastes and Anti-Dumping Policy.
To implement the above point "escencia" will have an anti dumping policy to insist all inhabitants must segregate and dispose waste at the collection points only. The wastes of different types are properly collected, segregated and sent for recycling, refurbishment minimizing or negating dumping to landfills.
10. Captive power generation
Power generation using BIO-GAS generated from garbage and bio degradable waste.
11. Reduction in Energy Consumed by Utilities such as Water Pumping Stations, Treatment Plants, Street lighting- Hence, lower Maintenance Costs.
All pumps at pumping stations, STPs, street lighting shall be low energy consuming, efficient systems so as to reduce common area loads.
12. Minimum Renewable energy compliance for the township total power requirement under GRIHA
Traffic signals powered by solar energy.
13. Renewable Energy based Traffic Signals within the township.
Traffic signals powered by solar energy.
14. Use of low embodied energy materials and construction technologies.
The total amount of energy required to manufacture a product should be as little as possible.
This includes considering resource excavation and extraction from the Earth, use of manmade materials in production, and complexity of manufacture. The simpler the process, the less harm done to the environment.
Vast amounts of energy are used in the production of building products. One product's "embodied energy," sometimes involves a complex series of processes that contribute heavily to the pollution of our environment, the depletion of nature resources and the degredation of the Earth.
15. EPI* of new residences, new Commercial building, new Institutional building, new healthcare buildings to be proposed as per BEE guidelines.
EPI stands for Energy Performance Index. All buildings to be controlled by Ansals shall follow the EPI norms as specified by Bureau of Energy Efficiency.
16. Water conserving parks and gardens.
Start with the soil in the landscape and garden. Improving the quality of the soil by adding organic matter like compost will enable the soil to soak in and retain moisture.
Make the landscape design eco-friendly by designing it to conserve water naturally. Plant taller shrubs and trees to provide windbreaks and afternoon shade to the landscape plantings and garden sp less soil moisture will be lost through evaporation.
Group plantings according to their water need when designing a landscape. Thos that require the most water should be planted near each other to utilize any water run-off.
17. Warer Efficent Landscaping - Drought Resistant species, Drip Irrigation.
A comprehensive landscaping is planned to provide a better green environment. The main area for landscape / plantation is the on the boundaires, park and open space. On the entire development about 11.8 acre of land is carved out for green spaces.
Selection of the plant species will be done on the basis of their adaptability to the existing geographical contitions and the vegetation composition of the region. During the landscape emphasis shall be given on selection of plant species like nitrogen fixing species, species of ornamental values, species of very fast growth with good canopy cover etc.
- The species will be fast growing and provide optimum penetrability.
- The species that will be wind-firm and deep rooted.
- The species that dorm a dense canopy.
Species that are tolerant to air pollutants like SPM, SO2 & NOx will be preferred.
Trees with high foliage density, leaves with larger leaf area and hairy on both the surfaces.
Ability to withstand conditions like inundation and drought.
Soil improving plants (Nitrogen fixing, rapidly decomposable leaf litter).
Sustainable green cover with minimal maintenance.
18. Trees and Landscaping with large shading area so as to minimize HEAT ISLANDS.
The temperature of urban areas are more when compare to the suburbs. This is due to the re radiation of heat from the buildings, road and foot paths. This effect is called urban heat island. Trees and landscaping with large crown or shading areas would be used and exposed surface of lower absorption would be used so that there is not much temperature difference in surroundings owing to different absorption and reflection properties. This would help maintain constant temperature and reduce heat islands.
19. Annual Water and Energy Audits.
Annual energy and water audits are planned so as to check whether all installed systems are working as efficiently as designed.
20. Construction activity pollution prevention
During Construction, prevention of soil erosion by wind or water so as to minimize dust generation during construction.
21. Pedestrian Infrastructure facilities to enable pedestrians to walk comfortably.
The entire community is connected by a green corridor in such a way that the inhabitants can walk across from one end to another. These corridors will be planted with avenue plantation to create an environment which encourages pedestrian movement.
- wider side walks
- street furniture like benches , trash receptacles will be provided at strategic points
- well lit pathways to encourage usage in night
- all pedestrian ways will be provided with curb ramps to enable physically challenged to pass thru.
22. Public Transport
A well planned public transport connectivity is in place to reduce No of PCU in the community.
23. Avalability of non motorized facilities.
A well planned cycle track is integrated along the 24m and 18m road
24. Road Safety
Road Safety signs and signals will be spread throughout the township to enforce disciplined traffic movement and pedestrian comfort.
25. Availability of parking Spaces
Planned road side parking lots are planned along the internal roads
26. Integrated land use transport system
The community is provided with bus stops, taxi stand, cycle track, etc to achieve efficient transport facilities.
27. Measure of Pollution levels (annual mean concentration of SO2, NO2, SPM and RPM, Noise levels in residential and non residential areas) (macro level).
Air, Noise and Water pollution levels would be checked throughout the township and if they seem to exceed, corrective measures would be taken.
28. Measurement and improving of Average Indoor air quality (micro level)
Measuring and improving indoor air quality of public buildings done by Ansal in the township so as to ensure good and healthier standards of living
29. Measurement and improving per capita carbon emissions
The avg. carbon footprint per person of the township would be calculated and corrected if beyond defined limits.
30. Reduction in transportation within the township with easy access to convenience stores and other basic amenities from every plot
To ensure that convenience outlets are at walking distance for the entire township so as to minimize use of vehicles.
