The main objective of the coursework is to
 develop an understanding of the factors which determine thermal comfort in indoor domestic spaces. At the end of this coursework, the student should be able to:  Have a basic understanding of some experimental methods such as monitoring, observations and estimates.

 Demonstrate an adequate level of academic report-writing skills, including analysis and presentation of data, and clarity in assumptions for graphs and calculations.  Demonstrate a good understanding of thermal comfort theory/variables, as well as a basic knowledge of the main thermal comfort standards.

For this exercise you are to install a datalogger in the main living space of your current home to record temperature and relative humidity over time. The datalogger will be set to sample conditions every 15 minutes, and collect one week’s data, including a weekend and periods when the heating system is operational. While the logger is installed keep a diary of when the heating is on, when windows are open and when moisture production occurs. Record you thermal comfort vote at different times during the week.

If you are unable to attend the seminar and collect the logger, email Dr Marcella Ucci (m.ucci@ucl.ac.uk) as soon as possible to make alternative arrangements. When you collect your logger, MAKE

A NOTE OF THE SERIAL OF YOUR LOGGER AND
INPUT it in Column Q of the Excel file ‘ede2014 student list’ on Google Docs https://docs.google.com/spreadsheet/ccc?key=0AtWXXUz5dygidEYwdjhiNDhKUGo 4bUxxNkhzWk9HaEE#gid=0 .
The serial number is written on a label on the back of the logger below U12-012. An example serial number is #1080773.
EDE staff will monitor outdoor temperature and humidity for central London, where most of the class lives. This will be converted to be in EXCEL format, and will be distributed to the class at the end of the monitoring period.

Once you have the down-loaded your data onto a PC, convert the data into an EXCEL spreadsheet, and plot out the results. EXCEL software can be found on most of college’s PC clusters, including the cluster at Central House. Plot out the data over the whole period of monitoring. Also plot out representative days to illustrate how your living space responds to the changing outdoor conditions and to periods when the heating is on and off. Consider how you are presenting your data: sometimes it is clearer to have temperatures on one graph and absolute humidity on another. Further suggestions on data analysis are provided in the ‘Additional Notes’ section at the end of this document.

Armed with these results and using the tools provided (see Notes), write a report on the thermal performance of your living space, and the comfort...
