简要总结
To enable the Netherlands to reach the 2030 carbon emission goals, older homes need to be renovated to become more energy-efficient and comfortable. This project aims to provide shallow renovations of window films. These shallow renovations can be completed in 1-2 days and cost significantly less than a deep renovation. The study aims investigate how such window films can affect humans (low-e film and thermochromatic) if applicated in real life.
详细描述
This study consists of one screening session (1.5 hours) and two testing sessions (5.5 hours each)
Screening session:
In the screening session, a questionnaire about general information as well as a medical questionnaire that asks about, current health status, lifestyle, morningness-eveningness chronotype, use of contraceptives, and sleep quality are completed. This data is necessary to assess the eligibility and to analyse the collected data with consideration of possible effect of lifestyle.
Testing sessions:
Subjects will be exposed to 2 different conditions (window film vs. no window film) in two days (11:15- 16:45) to assess the window film(s) influence on visual and temperature comfort, sensation and perception. The exposure rooms are low-e film room (film 1) or a thermochromic film room (film 2), compared with no film room (control). These films will be applied to windows. 2 cognitive cognitive tests, 2 vision tasks and fill in questionanires at set times are performed. Also wearable sensors as mentiond in Part 3 section 2 to measure their physiological parametersm suchs as skin temperature, heart rate and physical activity. Lastly, every hour a saliva sample by spitting into a tube to measure the cortisol level in the saliva is provided. Saliva is collected to measure cortisol changes caused by the environment. The samples are then stored immediately in a -20 freezer, after it is transported to the storage lab they will be centrifuged for 2 mins at 1000g and then stored in a
