Background In the last several years, a growing body of scientific evidence has indicated that the air within homes and other buildings can be more seriously polluted than the outdoor air. This observation is valid even in the most industrialized and advanced counties where stringent air quality regulations exist. Other statistics indicates that people spend approximately 90 percent of their time indoors. Thus, for many people, the risks to health may be greater due to exposure to air pollution indoors than outdoors. Further, people who may be exposed to indoor air pollutants for the longest periods of time are often those most susceptible to the effects of indoor air pollution. Such groups include the young, the elderly, and the chronically ill, especially those suffering from respiratory or cardiovascular disease. 2. About the IAQ Workshop Considering Indoor Air Quality (IAQ) as a serious issue, many countries have instituted IAQ standards and have come up with strategies that address Indoor emissions and control. These countries have focused not just on residential areas but have addressed commercial offices/complexes, auditoriums and even air conditioning buses/trains. Today there are no IAQ standards in India and research on IAQ and health is rather “thin”. Idea was to get researchers/academia, regulators, policy makers, architects, health specialist, business and MEP designers/ HVAC system designers and manufacturers on the same platform. The focus was to present a roadmap and invite peering and discussions for taking it ahead to the Ministry of Environment & Forests, Government of India. The was conducted as a part of Environmental Management Centre’s (EMCs) Ekonnect Seminar Series and in partnership with Civil Engineering Department of Indian Institute of Technology, Delhi. 3. Programme The workshop had a blend of presentations and panel discussions. The presentations were focused on the following topics: Welcome Address and first presentation was done by Dr. Mukesh Khare (Civil Engineering Department, IIT Delhi). Road map for Management of Indoor Air Quality – by Dr. Prasad Modak (Executive President, EMC, Mumbai) EMC 2 April 12 Proceedings of Workshop on IAQ These two presentations were followed by a Panel discussion conducted by Dr. Prasad Modak. Panelists included J. S. Kamyotra (Member Secretary, Central Pollution Control Board), Dr. Priyanka Kulshreshta (Lady Irwin College, Delhi University), Mr. Mahesh Dhongade (Honeywell Automation India Ltd.) and Mr. Pradeep Kumar (TERI, Sr. Fellow and Associate Director of Sustainable Habitat Division). The panelists reacted to the Road Map and offered their views. During and after the Panel discussions, participants made various observations, shared experiences and made suggestions. Please refer to Annexure 1 for the detailed programme. The workshop was attended by around 35participants. A list of delegates is provided in Annexure 2. 4. Proceedings a. Welcome Address and Concerns on IAQ Dr. Mukesh Khare, Professor, Civil Engineering, IIT Delhi welcomed the participants. After the welcome, participants did self-introductions. Figure 2 Dr. Saha asking a question to Prof. Khare Figure 1 Welcome Speech by Prof. Mukesh Khare, IIT Delhi Dr. Khare then made a presentation on IAQ related concerns and shared some of the relevant statistics especially related to IAQ and health. Research work carried out by IIT Delhi on IAQ was presented. Dr Khare highlighted some of the findings of this research. Mr. C. V. Chalapati Rao (NEERI) commented that most of the research studies presented were set in urban areas, and only few in rural areas. Prof. Khare replied in affirmative but added that, such studies have been conducted in India and referred to work done by Dr. Kalpana Balakrishnan. EMC 3 April 12 Proceedings of Workshop on IAQ Dr. D. Saha (Central Pollution Control Board - CPCB) proposed that IAQ should be considered as an essential part of the quality of life and just like the concept of sanitation, which is today, limited to availability of safe and adequate water and treatment & disposal of sewage. He further added that IAQ was perhaps not explicitly included n the mandate of CPCB and Ministry of Environment & Forests (MoEF). Dr. S. K. Tyagi, from CPCB, informed that CPCB has gone ahead and founded a committee for developing a set of monitoring protocol for IAQ. Prof. Khare was associated with the project. Subsequently, he hoped that this will lead to development of national policy & regulatory framework on IAQ. Dr. Gurnam Singh from CPCB stressed the need for having more inter-ministerial cooperation on IAQ related issues. To this Prof. Khare agreed and stated that these interventions are already built in the road map developed by EMC. Mr. Sanjay Kumar from Indian Railways mentioned that IAQ can be a critical issue given that Indian Railways operates over 3000 AC coaches every day. He asked whether any studies on IAQ were conducted, especially on impact of overcrowding on IAQ. Mr. Sandeep Mukherjee from EMC referred to a study conducted by Awasthi and others in Lucknow, wherein overcrowding in residential areas and IAQ were looked into. Prof. Khare asked Mr. Sanjay to review work done by Dr. Akhiledra Gupta from MNIT, Jaipur as well. Prof. Khare invited Dr. Prasad Modak, Executive President, EMC LLP to present the Road Map. b. Presentation of the Road Map Dr. Modak gave a presentation focusing on the IAQ related problems, studies carried out in India, economic and health implications and evolution of International standards. Figure 3 Keynote Speech by Dr. Prasad Modak, EMC EMC Figure 4 Dr. Priyanka making a point 4 April 12 Proceedings of Workshop on IAQ The key points of the presentation were as follows Dr. Modak stressed on a 3 pronged approach viz. (a) setting up a standards and regulatory framework for IAQ management, (b) source correction by promulgating material based emission standards, and (c) improved engineering control of IAQ He discussed the development of IAQ standards in various countries with special reference to China He then described the IAQ related requirements laid down in (a) National Building Code, 2005, LEEDS standard, IGBC and TERI GRIHA rating systems and AHRAE design codes for HVAC Dr Modak then discussed the linkages between IAQ, ventilation and energy consumption and role played by energy conservation/recovery measures and air cleaning equipment. Need for customized solution (contextualization) and optimization was expressed rather than limiting to segmented standards. He introduced EXPOLIS project of EU where multiple cities and institutions get involved in conducting exposure based IAQ & Health related research linked IAQ and Health impacts. He suggested that a proposal should be made to CPCB/MoEF drawing on the past experience of source apportionment project. Dr. Khare agreed to this. Dr. Modak requested Dr. Khare to prepare a draft proposal and approach MoEF. Establishment of Centre for Excellence in India on IAQ. Here, Dr Modak suggested that facility like INDOORTRAN may be considered as done in the EU. Dr. Modak presented a roadmap of Actions for the (a) Government; (b) for Business and (c) for Researchers / Academia. The roadmap contained probable actions divided into short (6 months to 1 year), medium (1 -3 years) and long term actions (>3 years). Mr. Pradeep Kumar, Sr. Fellow and Associate Director of Sustainable Habitat Division of TERI, Delhi observed the following: Compared to monitoring, modeling, measurement and exposure assessment mitigation of poor IAQ is more difficult and has to be addressed. We need studies on Indoor vs. Outdoor air pollutant concentrations Since India is a diverse country with different locations, climatologically diverse division, house building practices, natural ventilation etc. having one single uniform IAQ standard will not be applicable. Prof. Khare replied to Mr. Pradeep Kumar that there are several researches, conducted by him and that Prof. R.S. Patil of IIT Bombay that focus on Indoor /Outdoor pollutant relationship. Mr. Sandeep Mukherjee from EMC replied to Mr. Pradeep Kumar saying that perhaps the focus of the indoor air quality standard should be on exposure of individuals, and not on concentration. This way the location bias could be overcome. EMC 5 April 12 Proceedings of Workshop on IAQ Dr. Saha shared his experience that in 1995 he was in Canada, and found a METONE monitor which report PM1 and PM2.5 in a building. He then requested METONE to provide one such equipment for Agra Regional Laboratory of CPCB, which they happily installed. He commented that manufacturers of IAQ monitoring and control should be contacted on similar basis to set up pilots. Taking cue from Dr. Saha’s and Dr. Gurnam Singh’s query, Dr. Modak emphasized how inter ministerial collaboration is required to tackle IAQ related issues. He added that municipal corporations under the Ministry of Urban Development (MoUD) are responsible for publishing their environmental performance in an Environmental Status Report (ESR). Also Ministry of Environment & Forests (MoEF) comes up with yearly Report to Citizen of India - Status of Environment Report (SoER). IAQ could be a part of both the reports. He emphasized how a cinema hall chain, say like PVR could boast on its IAQ related performance in advertisements. This could leverage on their brand and hence sales. He further gave examples of industry’s participation in source control and IAQ improvement, like Suzlon Earth One and Godrej's effort in obtaining Green Guard rating for furniture. Dr. Tyagi and Dr. Gurnam Singh added that in line with BEE rating of energy consumption of buildings a star rating based IAQ monitoring & reporting scheme could be developed, which could be used for reporting IAQ to general public. c. Panel Discussion Dr. Modak invited the following panelist to come on dais and introduced them to the audience. Dr. Priyanka Kulshreshtha, Professor, Lady Irwin's College for speaking on IAQ and health Mr. J. S. Kamyotra, Member Secretary, Central Pollution Control Board to bring in the regulatory perspective into consideration Mr. Mahesh Dongade, Manager, Honeywell India Automation Ltd. to comment from industry’s point of view specific to Air Quality Cleaning Mr. Pradeep Kumar, Sr. Fellow and Associate Director of Sustainable Habitat Division of TERI, Delhi to speak on Building Codes and Rating Systems Dr. Priyanka Kulshreshtha spoke on the relationship between Indoor Air Quality and Disease Adjusted Life Years (DALY). She concluded that her research showed that there was a positive correlation between high indoor pollutant levels and more DALY. Mr. Mahesh Dhongade from Honeywell discussed about Honeywell’s effort and equipment in IAQ sector. He emphasized the need of relating IAQ to energy consumption and opined that these are not necessarily antagonistic in nature. EMC 6 April 12 Proceedings of Workshop on IAQ Mr. Pradeep Kumar shared his experience on IAQ esp. through the TERI GRIHA programme. He also added points from practical experience on difficulties of measuring and monitoring IAQ. Dr. Modak asked Mr. Kamyotra to comment on the points raised by other speakers. Mr. Kamyotra stressed that focus should be on Indian context in understanding the IAQ problem as well as in proposing solutions. Regulations alone will not work and we need a multi-pronged strategy. Dr. Modak then opened the floor for discussions. Figure 5 Mr. Mahesh Dhongade from Honeywell making a point on IAQ & HVAC designs Figure 6 Dr. Priyanka Kulshreshta speaking on IAQ & DALY relationships Figure 7 Ms. Madhumita Ghosh Ray from Paharpur Business Centre describing their biological air filtration system Figure 8 Mr. Pradeep Kumar making a point on Building Codes during his Speech Dr. Saha asked Mr. Mahesh from Honeywell to share their experience / research on IAQ and related aspects and suggested that companies like Honeywell should generate IAQ data as part of the BMS. Mr. Mahesh replied by saying that Honeywell will certainly consider this possibility. EMC 7 April 12 Proceedings of Workshop on IAQ Mr. Pradeep Kumar started a discussion on IAQ, thermal comfort and productivity. He concluded that since productivity is affected by many aspects other than IAQ and /or thermal comfort, it is not possible to associate these terms directly. Dr. Saha asked whether it is possible that just by aligning the buildings in a specific direction it was possible to reduce accumulation of pollutants in a building. Mr. Pradeep answered that alignment it affects the natural ventilation and hence a requirement laid down in building rating systems. Mr. Pradeep shared his experience, that his team in year 2000 monitored Paharpur Business Centre. They have a plant based indoor air cleaning system. He said that at that time they have monitored CO, CO2, PM2.5, PM1 etc. His conclusion was that under the Indian pretext, both HVAC design and IAQ should focus on dust concentration and not just on CO2. Ms. Madhumita Ghosh Ray from Paharpur Business Centre (PBC) described their unique plant based air cleaning feature. She stated that they monitor the indoor air pollutant levels including CO, CO2 and PM2.5, and these parameters are well under check. To this Mr. Sandeep Mukherjee from EMC asked that since the building depends on biological entities for cleaning its air, have PBC monitored biological parameters in air like pollens, bacteria and spore in air. To this Ms. Saghita Ghosh Roy from CPCB answered that during a study captioned “Epidemiological Study on Effect of Air Pollution on Human Health (Adults) in Delhi” in Delhi (Winter 2008) the bacteriological parameters at PBC were monitored. However, Mr. Mukherjee stressed on the need for more frequent monitoring of such parameters. Prof. Khare added that IAQ should be used as ‘Sustainability Indicators’ of a building and /or of a project. For this purpose a set of direct/proxy indicator should be developed, and these should be used in design rating programme. Same or similar indicators could be used in building performance rating system like LEEDS and GRIHA. Dr. Modak requested Mr. Kamyotra to sum up and give his observations. Mr. Kamyotra reiterated that there is a need to adopt India centric technology to measure and monitor IAQ, and similar pragmatic approach is required while setting a standard. He also emphasized that there is a distinct need to change habit and got back to our traditional roots, which where environment friendly. He reiterated CPCB’s concern on IAQ, and said CPCB is working towards development of a monitoring protocol for IAQ. He questioned about difficulties in establishing definitive relationship between IAQ and health. He added that it is important to monitor and develop a standard on IAQ; however at the same time economic concerns should also be included into decision making process. He concluded by saying the proverb “Jaan hai to Jahaan hai” should be reversed to “Jahaan hai to Jann hai”. EMC 8 April 12 Proceedings of Workshop on IAQ d.
