6 Buildings: An essential sector in climate change Mitigation
Through creation of intelligent green buildings With estimated 60% of global energy consumption, the operation of buildings contributes more to energy use and climate change than either transportation or industry. To meet the emerging climate change and carbon challenge the human settlement needs retrofitting. Buildings have to be planned & designed with an holistic and integrated approach, so that they contribute in enhancement of the City environment, Greenery, Energy & Water efficiency, Human comfort, Quality of life.

7 INDIA’S NATIONAL ACTION PLAN FOR CLIMATE CHANGE
1. National Solar Mission – To increase the share of solar energy and other renewable and non-fossil based energy sources 2. National Mission for Enhanced Energy Efficiency – To promote energy efficiency through star labelling system and energy conservation building code (ECBC). 3. National Water Mission - By 2050 it states that India is likely to be water scarce thus National Water Mission thus aims at conserving water, minimizing wastage and ensuring more equitable distribution through integrated water resource management. 4. National Mission for a Green India - It builds on the Prime Minister’s Green India campaign for afforestation of 6 million hectares and the national target of increasing land area under forest cover from 23% to 33%. 5. National Mission on Strategic Knowledge for Climate Change - To work with the global community in research and technology development and collaboration through a variety of mechanisms and, in addition, will also have its own research agenda supported by a network of dedicated climate change related institutions and universities and a Climate Research Fund. The Mission will also encourage private sector initiatives for developing innovative technologies for adaptation and mitigation. 6. National Mission for Sustaining the Himalayan Ecosystem. 7. National Mission for Sustainable Agriculture. 8. National Mission on Sustainable Habitat – Green Building Design practices with integrated holistic and inclusive approach will help to achieve this target.

13 INTEGRATED APPROACH & PLANNING FOR GREEN BUILDING DESIGN
(SUSTAINBILITY IS NOT BELOW IN THE – LINE ITEM ) Do you think “Integrated Approach & Planning for Green building design” leads to escalate the project cost??? Answer is “NO” In fact, this approach minimizes the regulatory risk & also support Climate Change mitigation measures. This approach also add value in the project by providing long term paybacks & benefits in terms of energy & water savings This approach also defines “Social Responsibility” & contributes in the Sustainable Development & Green Economy. If you are unable to hear the speaker please dial /

14 INTEGRATED APPROACH & PLANNING FOR GREEN BUILDING DESIGN
(SUSTAINBILITY IS NOT BELOW IN THE – LINE ITEM ) As per various Global studies, it was proved that Green Buildings do not require additional cost, if design project team have thorough knowledge of Green & Sustainable parameters, have the capability to incorporate & integrate these features in the planning stage of design. The perception of additional cost remains in the mind set of those people, who consider sustainability parameters as additional features in the project. When establishing a design and a budget for a Green Building, the key point to remember is that “Sustainability is a program issue”, rather than an added requirement. If you are unable to hear the speaker please dial /

15 INTEGRATED APPROACH & PLANNING FOR GREEN BUILDING DESIGN
(SUSTAINBILITY IS NOT BELOW IN THE – LINE ITEM ) The first question in budgeting should not be “How much more will it cost?,” but “How will we do this?” This must be done as early as possible in the project and it must be considered at every step of design and construction. This is done by: • Establishing team goals, expectations & expertise (Architect, Env. Planner, MEP experts, landscape, Site Analyst etc.). We need the complete team on board to start design • Including specific goals in the Program • Aligning budget with program. • Staying on track through design and construction Perhaps the most important thing to remember is that sustainability is not a below in - the-line item. (Need to be treated “First Thought” in the mind) If you are unable to hear the speaker please dial /

16 SYNERGY OF COST WITH CURRENT ENVIRONMENTAL
POLICY & DESIGN REGULATIONS IN INDIA There is no doubt that better understanding of Environmental Policy & applicable design regulations for each region in India, to incorporate specified sustainability parameters of the policy & regulations in the planning stage itself leads to define the exact cost of the project planned. Hence there is no point of additional cost. Under EIA notification 2006 of MoEF, Environmental Clearance is mandatory for all construction projects (more than 20,000 sq.mt BUA). If you are unable to hear the speaker please dial /

17 Design Planning as per NBC (climatology/ orientation)
SYNERGY OF COST WITH CURRENT ENVIRONMENTAL POLICY & DESIGN REGULATIONS IN INDIA The following sustainability parameters have been covered as mandatory part of project design & implementation in India. Site Planning as per NBC (retaining topography, landscape, soil erosion measures etc.) Design Planning as per NBC (climatology/ orientation) Energy Management & design (ECBC/ BEE – building envelope & Energy Efficient technologies) Water Management & design (NBC, BIS, IS, CPCB) Material Management (fly ash notification of MoEF, procurement of Green materials) Construction Management Plan & Compliance monitoring reports is a part of regulatory frame work. **Note – The above parameters are prescribed in the mandatory conditions of Environment clearance issued. If you are unable to hear the speaker please dial /

18 SYNERGY OF COST WITH CURRENT ENVIRONMENTAL POLICY & DESIGN REGULATIONS IN INDIA
In fact, it is also clearly defined in the prescribed Environmental conditions that “Occupancy Certificate” should not be issued to the project until all Environmental Infrastructure & Sustainability parameters have not been installed, commissioned & validated by the Local Corporation bodies. Need & Challenges: Lack of Environmental Policy awareness in the architectural education system (induction of legal policy & Green parameters in the Education syllabus) Intent of Developers to implement the required mandatory norms on the ground (paybacks & benefits understanding required. Govt. incentives schemes may encourage the same) Lack of expertise (Trainings need to be provided to the execution team) If you are unable to hear the speaker please dial /

19 SYNERGY OF COST WITH CURRENT ENVIRONMENTAL POLICY & DESIGN REGULATIONS IN INDIA
Some of the states have already initiated incentive schemes for their regions to encourage Sustainability….. Gujarat Govt. has mandatory RWH policy, Solar policy, & integrated water management facility for recycling & reuse of waste water. Also provides Rs.9.47 for 1 unit of electricity generation under the export policy of Renewable Energy directly connected with grid, it’s a long term payback (Monthly). Thane, Maharashtra has mandatory solar water heater policy & provide tax benefits & various other Green parameters. Tamil Nadu has also well defined solar policy & subsidy/ incentive benefits. RWH(Refund policy), Penalties are also well defined. If you are unable to hear the speaker please dial /

20 SYNERGY OF COST WITH CURRENT ENVIRONMENTAL POLICY & DESIGN REGULATIONS IN INDIA
In Bangalore water Supply & sewerage board proposes tax rebate on RWH filters. (Relaxation of VAT for key components used in the installation). Other tax rebates in the implementation of renewable energy.  The UERC (Uttarakhand electricity Regulatory commission) rebate is paid in addition to the central government investment subsidy, which is 60% of the SWH benchmark costs. PCMC (Pimpri Chinchwad Municipal Corporation) rebate in property tax & builders premium for Green buildings. (GRIHA rated), MNRE incentives to GRIHA rated projects. 0.25% concession in the interest rate by State Bank of India for home loans. Faster Environmental approvals for IGBC & GRIHA Pre- certified projects. Still Govt. needs to streamlined the incentive policies for all the states from Central & Regional level to encourage implementation of Sustainability parameters. If you are unable to hear the speaker please dial /

21 INTEGRATED APPROACH & PLANNING FOR GREEN BUILDING DESIGN
(SUSTAINBILITY IS NOT BELOW IN THE – LINE ITEM ) CONCLUSION Incorporation of all sustainability parameters defined as per legal regulations (EC) in the design planning itself leads to create an integrated design approach & also complement the requirements of Green Building norms in the project design, reduce the regulatory risk & keep no option for “adoption of green” separately. Hence legally compliant projects have no additional cost. If you are unable to hear the speaker please dial /

22 It can be used in residential & commercial structures both.
GREEN BUILDING & GLAZING COMPLIANCE FOR SUSTAINABLE DESIGN & COST EFFICIENCY Can we assume a building without any opening, where there is no outer connectivity? – “No” What we need? – An adequate material in the building opening, which can allow us to view the outer world & also reduce heat gain – i.e. “GLASS” Glass is an excellent green material, if used intelligently. Certain glasses like solar control glasses  can reflect heat or UV rays and maintain optimal temperature inside the building. They let in great amount of natural lights to energize the interiors. Thus glass in buildings substantially reduces the need for artificial lighting and allows day-light to light the interiors. It leads to achieve higher energy efficiency in the Green Buildings. It can be used in residential & commercial structures both. If you are unable to hear the speaker please dial /

23 Climate zone– 5 climatic zones of India as per NBC
GREEN BUILDING & GLAZING COMPLIANCE FOR SUSTAINABLE DESIGN & COST EFFICIENCY For the selection of appropriate Glass suitable to a specific design of a building depends upon following parameters. Climate zone– 5 climatic zones of India as per NBC Building orientation – Maximum openings/larger façade should be in north & south and buffer spaces in the west & east. Wall Window ratio – The ratio of vertical fenestration area to gross exterior wall area. If you are unable to hear the speaker please dial /

24 GREEN BUILDING & GLAZING COMPLIANCE FOR SUSTAINABLE DESIGN & COST EFFICIENCY
SHGC – the ratio of solar heat gain entering the space through the fenestration area to the incident solar radiation, typically ranging from 0.9 to 0.1 where the lower value indicate lower solar gain U value – Heat gain due to temperature difference is expressed by U-Value of a glass. It is the amount of heat transferred (loss/gain),due to a temperature differential of 10C between inside and outside per square meter. Shading design – to reduce insolation & heat gain like pergolas, chajjas, jallis, overhangs, green wall or plantation on east & west sides. If you are unable to hear the speaker please dial /

29 Tangible & Intangible benefits of glass:
GREEN BUILDING & GLAZING COMPLIANCE FOR SUSTAINABLE DESIGN & COST EFFICIENCY Glass with low U value & low SHGC gives good energy performance in tropical climate whereas a glass with low U value and high SHGC gives good energy performance in the cold climate. Tangible & Intangible benefits of glass: Intangible Benefits: Psychological connection to the outside world. Reduce visual fatigue Improve health & Increase productivity Tangible Benefits: Comfortable lighting conditions/ reduction in the load on lighting power Daylight sensor reduce the artificial lighting needs & increase the life of fixtures. Low U value & low SHGC reduces the heat ingress resulting into decrease in HVAC load & energy consumption. Glass has recycled content & provide regional materials credits In LEED, Glass contributes 4 points & in GRIHA it has great impact on criterion 13 & 14 (to reduce conventional energy demand & to optimize energy performance of the building). ** Note – Comprehensive Energy Simulation studies with the help of all the stakeholders leads to reap the maximum benefits.

30 CONSTRUCTION PRACTICES AND POST OCCUPANCY PRACTICES FOR GREEN BUILDING DESIGN
Do you think Sustainable construction practices increase the cost??? “NO” In fact, these practices will keep the site healthy, will not disturb the ecosystem & will minimize the impact of project activities on the Environment, also conserve & preserve natural resources, this will lead to increase in the productivity & healthy/safer environment for construction workers & site project team. Construction Management Plan needs to incorporate the conditions & guidelines to comply all sustainable practices required as per Green Building norms (MoEF guidelines may also be referred) Contractors terms & conditions should be updated accordingly. Responsibility needs to be identified for the implementation & monitoring of the compliances on site. Action plan should be executed & monitored continuously.
