1. CIBSE working groups, UKIEG and UCL want to hear your views!
Deadline: 5pm GMT 9th April 2020. 

This survey aims to summarise views of professionals working in the UK built environment sector on air quality metrics. Given we spend on average 60 years inside buildings, indoor air quality (IAQ) has a significant impact on our lives- health, wellbeing and productivity (1,2,3). Different sources [building certification schemes (BREEAM, LEED, WELL), Building Regulations (Part F), World Health Organisation (WHO) recommended indoor air pollution levels] have varying threshold levels for different pollutants.  

We have developed this short survey to understand how you are using two common indoor air quality metrics (CO2 and TVOC) in building design and operation. CO2 stands for carbon dioxide. TVOC stands for total volatile organic compounds. 

By completing this survey, you agree that your personal details will be used for research purpose of the survey to provide background information on respondents in report. Your personal details will not be shared without your prior permission.  During the duration of the survey, they will be protected in line with UCL GDPR regulations. Only the line of occupation and companies could be used to provide an overview of the participants in the survey. Your names and e-mails will only be used for distribution of the survey results. Once your views are collected, you will receive a summary of the findings in the form of a joint CIBSE, UKIEG and UCL report. Once the data is collected, a summary of respondents will be prepared. Once the report is shared, all personal information (names, organisation, e-mail) will be deleted permanently. 

The Data you provide directly will be stored by Survey Monkey on their servers in the United States. We have taken all necessary precautions to ensure that your rights in terms of data protection will not be compromised by this. 

Should you have any questions about the survey, your personal details, information handling please contact the data protection officer at: ucqbdn1@ucl.ac.uk
