recertification of green buildings could become another require- ment in certification schemes to assure that favorable IAQ levels are attained and maintained。
In conclusion, the following long-term actions can help promote favorable IAQ in green buildings: (1) Requiring indoor air quality guidelines for key pollutants and awarding credits for their reduction or avoidance; (2) Developing an IAQ index or metrics; (3) Requiring or awarding credits for emission testing of products used in green buildings; (4) Conducting monitoring of IAQ in green buildings; (5) Accounting for cross-category impacts of solutions in other categories on IAQ; (6) Requiring regular recertification based on IAQ levels; and (7) Overall, developing incentives to improve IAQ and in ways that benefit building occupants, employers, and owners, and that create higher recognition of IAQ in green building projects。
1。10。 What are the research gaps related to green buildings and IAQ?
Strengths and deficiencies of current green certification schemes relative to IAQ have been identified and discussed in this paper。 This section looks at opportunities for research to bridge the knowledge gap between green building practice and potential, enabling green buildings to create and promote better IAQ。 The list of research priorities below does not include issues that affect buildings more generally, such as the links between building products and practices, indoor air quality, and health effects。 While this research is also needed, the points below are as specific to green buildings as possible。
1。 Determine attributes of green buildings that can improve IAQ, and specific actions that can make a building green or healthier relative to IAQ。
2。 Evaluate the effectiveness of existing and new credits for pro- moting IAQ in green buildings, and the relationship between credits awarded and measurable effects on IAQ。
3。 Develop key performance indicators, such as acceptable indoor air quality levels, for certification and re-certification of green buildings。
4。 Identify green consumer products and building materials that have improved or impaired indoor air quality in green buildings, and investigate their emissions。
5。 Assess attributes of green buildings relative to IAQ as expected and rated by the building occupants。
6。 Conduct controlled comparative studies of IAQ in green build- ings with matched conventional buildings, and controlled intervention studies of conventional buildings converted into green buildings, and measure differences in IAQ。
2。 Conclusion
Green buildings have the potential to promote more favorable indoor air quality。 On balance, based on available but limited data, perceived IAQ is better in green buildings than in conventional buildings。 However “green” does not necessarily guarantee good indoor air quality。 Certification schemes may provide inadequate incentive in the credit system for improving indoor air quality。 Also, certain green practices and green products could actually impair indoor air quality。 The focus on ventilation as a primary method for IAQ control overlooks opportunities for source control and expo- sure reduction。 Given that people spend most of their time indoors, and that people are the most valuable asset in a building, it seems practical and prudent to make investments in overall green build- ing programs and inpidual buildings to ensure healthful IAQ。
本文研究的关注，绿色建筑可能会促进能源效率和其他—方面的可持续性，但不一定是居住者的健康和福祉通过更好的室内空气质量（IAQ）。我们探索绿色建筑室内空气品质的挑战以及机会问十个问题—室内空气品质改善的机会在绿色建筑和他们的节目。我们的重点是室内空气品质，同时识别—组织的因素很多，影响人体健康和建筑物的健康。我们从一开始绿色建筑室内空气品质的概述，以及是否和如何解决室内空气品质的绿色建筑认证。下一个，我们检查是否有绿色建筑比传统的空气品质高的证据建筑.然后，我们确定所谓的绿色做法和绿色产品，可以有意想不到的对室内空气品质的不利影响。展望未来，我们提供即时和长期的行动，以及一套研究问题，可以更有效地促进绿色建筑室内空气品质。本文支持对室内空气品质的绿色建筑的重要性，越来越多的认可，并有机会提高—要求。正如世界绿色建筑委员会（95）和其他人所强调的，人是最对组织有价值的资产，努力提高空气质量可以改善健康，福祉，生产力，和盈利能力。
