13.2 Provisions for City And Site Level Greening
In alignment with National Sustainable Habitat Mission, the Administration/Authority shall encourage augmentation of green cover in the city/plot, by following:
(i) Provision of minimum 1 tree / every 80sqmt of plot area for plot sizes > 100sqmt and planted within the setback of the plot.
(ii) Compensatory Plantation for felled/transplanted trees in the ratio 1:3 within the premises under consideration.
(iii) Choice of species for plantation in site and abutting the road to be adopted as per Section 8 of the Urban Green Guidelines, 2014.
(iv) The unpaved area shall be more than or equal to 20% of the recreational open spaces.
13.3 Water Re-Use and Recycling
i. All buildings having a minimum discharge of 10,000 Ltr. and above per day shall incorporate waste-water recycling system. The recycled water shall be used for horticultural, flushing and cooling tower purposes.
ii. The dual pipe system shall be adopted for these buildings.
13.4 Installation of Solar Assisted Water Heating System/ Solar Photo Voltaic Power Plant in Buildings
1(a) No new building in the following categories in which there is a system of installation for supplying hot water shall be built unless the system of the installation is also having an auxiliary solar assisted water heating system:
(a) Hospitals and Nursing Home.
(b) Hotels, Lodges, Guest Houses, Group Housing with a plot area of 4048 sq m.
(c) Hostels of Schools, Colleges and Training Centres with more than 100 Students.
(d) Barracks of armed forces, paramilitary forces and police.
(e) Individual residential buildings having plot area equal or more than 1 kanal (420 sq.mt).
(f) Functional Buildings of Railway Stations and Air Ports like waiting rooms, retiring rooms, rest rooms, inspection bungalows and catering units.
(g) Community Centres, Banquet Halls, Bhawans and buildings for similar use.
1(b) As regards to residential buildings, all houses on a site of one kanal will make provisions for solar water heating system having capacity of atleast 100 Ltr. and on a site of two kanals and above that of atleast 200 Ltr. The existing houses will provide these facilities within two years from the date these orders are notified in the official gazette.
II) Installation of Solar Water Heating System
(a) New Buildings: Clearance of plan for the construction of new buildings of the aforesaid categories shall only be given if they have a provision in the building design itself for an insulated pipeline from the rooftop in the building to various distribution points where hot water is required. The building must have a provision for continuous water supply to the solar water heating system. The building should also have open space on the rooftop, which receives direct sun light. The load bearing capacity of the roof should at least be 50 kg. per sq m. All new buildings of above said categories must complete installation of solar water heating systems before obtaining necessary license to commence their business.
(b) Existing Buildings: Installation of Solar Assisted Water Heating Systems in the existing building shall be made mandatory at the time, if allowed, to above said category provided there is a system or installation for supplying hot water.
(c) Capacity: The recommended minimum capacity shall not be less than 25 Ltr. per day for each bathroom and kitchen subject to the condition that maximum of50% of the total roof area is provided with the system.
(d) Specifications: Installation of Solar Assisted Water Heating Systems shall conform to BIS specification IS 12933. The solar collectors used in the system shall have the BIS certification mark.
III Installation of solar photo voltaic power plant For installation of solar photo voltaic power plant refer Annexure - 2
13.5 Sustainable Waste Management
Zero Waste is a concept of waste management and planning approaches that emphasize waste prevention as opposed to end waste management. This means restructuring production and distribution systems, designing and managing products and processes to systematically follow the 3R rule of Reduce, Re-use and Re-cycle the volume of waste, to conserve and recover all used resources, and therefore eliminating all discharges to landfills, and prevent air, water and land pollution. Zero Waste/ land-fill can be achieved by adopting systematic approach of segregation at source by planning, by collection facilitation and most importantly by creating public awareness.
The green waste can be converted into fuel cakes, kitchen waste into manure, construction & demolition waste into bricks, plastic waste into oil, paper, glass and steel back into the same and all residual inert materials can also be converted into bricks. Achieving zero land-fill is more conveniently possible, if
a) The collection is made from house to house and some segregation is done at household level
and separate wet and dry bins must be provided at the ground level.
b) The recycling is done at decentralized, say, ward or even lower levels.
13.6 Provision of Energy Conservation Building Rule
Competent Authority may require a class of buildings to be compliant with Energy Conservation Building Code ECBC Code 2007 and specify a procedure of its verification.
13.7 Suggested Sustainable Building Materials
The following supplementary building materials (derived or processed waste) may be suitably used while constructing building in combination with conventional resources:
i. Panels, hollow slabs, hollow blocks - Conservation of materials, less water requirement.
ii. Fly Ash bricks, Portland Pozzolana cement, Fly ash concrete, phosphor gypsum based walling & roofing panels, particle wood – Recycled use of industrial/agricultural by-products.
iii. Fly ash/ AAC (Autoclaved Aerated light weight Concrete) panels/ CLC (Cellular Light weight Concrete) panels- Ensures thermal comfort (significant reduction in air-conditioning requirement)
iv. Use of bamboo & rapidly growing plantation timbers- Environmental benefits.
v. Compressed Soil Earth Block and Rammed Earth Walls and Vaults-Environmental friendly.
14 POWER OF RELAXATION
The Chief Administrator, U.T, Chandigarh may relax any restrictions or conditions or norms stated in these rules , interpret or clarify or may issue direction to revise the Rules, if the relaxation or revision is in public interest.
15 REPEAL & SAVINGS
