1 Mainstreaming Sustainable Social Housing in India Project (MaS-SHIP) Regional Workshop 2 Testing of the Sustainability Index for mainstreaming sustainable social housing 3 rd April, 2018 Redfox Hotel, Jaipur

2 Introduction The second regional workshop under MaS-SHIP was held on 3 rd April 2018 at the Redfox Hotel, Jaipur, India. The regional workshop brought together the project team, advisory board members, academicians and building professionals from across Jaipur, with a total of 40 participants, to present and discuss the data collected so far against the parameters and the testing of the Sustainability Index assessment methods. The participants of the event came from varied backgrounds ranging from construction industry, private developers, architects, research institutes and academia. The objectives of Regional Workshop-2 were: To present the data collected so far for the selected materials and technologies against parameters of Environmental impact, Resource efficiency, Operational performance, User experience and economic impact. To gain insights from the attendees on the methodology adopted for assigning weightage of attributes in the MaS-SHIP Sustainability Index, for selecting the most appropriate building materials and technologies. Welcome remarks The meeting began with welcome remarks and opening of the agenda by Ms. Zeenat Niazi, Vice President, Development Alternatives. She underlined the intent of the project and the progress made so far. She explained that the project aims at producing two major outputs, one being the Sustainability Index (SI) which will enable building practitioners to assess the sustainability of the building materials and technologies chosen in their housing projects. Subsequently a Decision-Making Tool will be developed that will add value to the results received from the SI and will help other sustainability professionals to make appropriate choices with respect to sustainable building materials and technologies to be used in social housing projects. Keynote Address Mr. Tushar Sagoni, Zonal Representative for Green and Sustainable Committee for Arcasia, in his keynote address, reflected on the general lack of compliance to guidelines in all development projects. Being an architect, he believes the approach to all projects needs to be holistic. In most rating tools, not many points have been given to considerations for local climatic conditions, while the approach should be to Reduce, Reuse, Recycle and Rethink. Passive design measures should be followed. Upon this discussion a B3B Group member observed that the quality of construction cannot be expected from housing projects solely funded by Government bodies but a Public Private Partnership model will help in ensuring the overall Mr. Tushar Sagoni, Zonal Representative for green and quality of construction of the housing projects. Great Sustainable Committee for Arcasia emphasis was placed on the importance of solar-passive design techniques, planning, orientation and use of local materials and knowledge towards overall

3 sustainability of social housing and improving the living conditions of the economically weaker sections of society. Project updates Ms. Pratibha Caleb from DA introduced the project and the scope of the MaS-SHIP study. She went on to explain the sources of data collection and the type of data required under each attribute. She presented the results attained from the surveys conducted with manufacturers, building practitioners and households. Table 1: Source of data against each attribute SL Attributes 1. Embodied energy 2. Critical Resource Use 3. Current Recycled Content 4. Future Reusability 5. Water Consumption 6. Familiarity with the material/technology 7. Modification ability 8.

Noise transmission 17. Thermal Mass 18. Thermal Performance Secondary data Desk research Primary data Manufacturers Building Practitioners Households She spoke of the different social housing projects that were studied and presented the findings of the 150 household surveys that were conducted at the Kiron ki Dhani, Jaipur, under the Rajiv Awas Yojana (RAY) scheme. Responses from the households indicated that a key concern for them with respect to their dwellings was thermal comfort (especially, since their cooling strategies seemed inadequate) and the inability to modify the space within their home because of the cracks that would form when hammering a nail into the walls. Thus a critical learning from the household survey was the aspect of familiarity with the material/technology as well as the modification ability of the same. Ms. Zeenat Niazi then presented the results of manufacturer and building practitioners survey, with emphasis on the analysis of the building materials and technologies against the attributes.

The LGSFS analysis indicated that higher the steel consumption, as in the case of Light Gauge Steel Figure 1: Embodied energy of selected materials and technologies Framed Structures (LGSFS), the embodied energy is much higher, in comparison to more light weight structures manufactured in-situ for example plant and joist. Open Discussion This session was conducted by Mr. Vinay Joshi, President of Rajasthan Affordable Housing Developers Association (RAHDA), who stressed on the importance of solar passive design, planning and orientation according to the sun-path and wind-path as well as strategic window placements in low-cost housing design. The questions raised by the audience were directed towards the high initial economic impact of sustainable practices and how these practices can be incorporated without the added costs. According to Zeenat Niazi (DA) and Sanjay Seth (TERI), the answer lies in market based demands and establishing supply chains for the materials and technologies. Mr. Yash Pratap from Poornima University pointed out that the physical and chemical reaction of building materials is also largely dependent on climatic regions. Hence he questioned the possibility of incorporating the aspect of material behavior and user acceptance in different climate zones to the sustainability index and its subsequent linkage to the Decision Making Tool. Mr. Vinay Joshi, President of RAHDA) Testing the Sustainability Index Ms. Megha Behal from TERI presented the attributes of the Sustainability Index (SI) and the outline of the Decision Making Tool (DMT). It was explained that the short-listed 18 attributes were selected from an initial long list of 29 attributes through feedback from the earlier iteration of the AHP survey. The shortlisting was based on the availability of primary or secondary data sources for measuring or quantifying the attributes as well as multiple stakeholders with relevant sustainability experts. Each attribute has been analyzed in terms of quantity measured, the calculation method, the unit to be used as well as the formula

5 and data source. Following the explanation of the DMT, an exercise was conducted where all participants were sent a link to the AHP survey and were asked to fill in their responses. Analysis of the AHP Survey We received 21 responses from the survey. The majority of the respondent population who filled the surveys were primarily architects.

6 The duration of construction had maximum weightage followed by job creation and construction cost in economic impacts of selecting a building material and technology. Modification ability was given the maximum weightage by majority of the respondents. Water use during construction also came out to be among the important attributes in opinion of the respondents while selecting a building material and technology. However, user acceptance and economic impacts overall accounted for the maximum weights as per the responses.

7 Closing session The workshop came to an end on a high note, with several participants eager to continue to lend their support for the AHP survey as well as for offering their housing projects as pilot for the project. The vote of thanks was delivered by Mr. Arnab Gazi of the B3B group, who had not only supported the project team in conducting the workshop in Jaipur, but has also offered to collaborate with the MaS-SHIP team on applying the SI on one of their housing projects. Highlights of the Regional Workshop The discussion with the participants prompted the inclusion of behaviour/suitability of material according to climate zones B3B group proposed piloting the DMT in one of their upcoming projects. Emphasis was given to the importance of solar-passive design techniques.
