CPD PROGRAMME Responsible monitoring of built environments Continuing professional development (CPD) is the regular maintenance, improvement and broadening of your knowledge and skills, to maintain professional competence. It is a requirement of CIBSE and other professional bodies. This Journal CPD programme can be used to meet your CPD requirements. Study the module and answer the questions on the final page. Each successfully completed module is equivalent to 1.5 hours of CPD. Modules are also available at www.cibsejournal.com/cpd This module explores the recently published TM68 Monitoring indoor environmental quality and its guidance on the ethical approach to measurement, monitoring and data management The measurement of indoor environmental quality (IEQ) and the responsible management of resulting data is fundamental not only to control the building services systems, but also to assess and improve the opportunities for success in creating safe and responsible built environments. This CPD will draw selectively on the recently published Technical Memorandum 68 Monitoring indoor environmental quality (TM68), and will specifically focus on the guidance on the ethical approach to measurement and monitoring of built environments, as well as the increasingly challenging task of responsible data collection and management. The much misattributed and misquoted adage If you cant measure it, you cant manage it provides a suitably succinct reminder of the need for a robust and appropriate sensing, monitoring and data management regime for building services systems. There has been much written about the performance gap, and there are increasingly urgent demands on building operators to moderate energy usage, operational costs and environmental impact while maintaining safe and healthy built environments. The publication of the new TM68 is, therefore, a particularly well-timed addition to the CIBSE catalogue. Although the TM does not profess to be an encyclopaedic reference, it effectively provides an excellent framework by covering key requirements for environmental measurement, monitoring and associated data management in buildings. (Much of this article is based on abstracted and abbreviated text taken from the TM for more complete detail, see the TM, freely downloadable for CIBSE members.) TM68 provides an overview of how data collected in real buildings can convey meaningful information about IEQ by providing primers on current technologies and recommendations. It notes that priority has been given to factors that directly impact occupants comfort and wellbeing. The initial chapter provides a summary of the most important issues to be considered before embarking on an IEQ monitoring project, such as stakeholders involvement, ethical considerations and privacy issues, among others. The following four chapters thermal comfort, air quality, luminous quality, and acoustic quality examine units and performance metrics, available instruments and sensors, practical sampling considerations, and reallife case studies. These four chapters are not considered further in this article which is not to diminish their importance or the quality of the work, but simply in order to focus on some of the more novel aspects covered in the TM. The final chapter of the TM provides a rare contextualisation for built environment professionals of continuous sensing systems and data management this will be explored in more detail later in this article. For those who are research active, the potential impact of measurement on building occupants has long required a formal assessment prior to any activity being undertaken. The TM gives an early airing to ethical issues that, historically, may not have been seen as relevant to, or previously given the priority by, practising building services engineers as much as they are today.
