Surveys Hobo's Surface Temperature Hypothesis
Conclusion Building Vital Signs Arch 502 Home
In order to study the building, we needed to use some devices that could record environmental data instantly or for long periods of time. The devices we used were HOBOs, a spot pyranometer, and a pyranometer.
HOBOs
HOBOs are used to record temperature data for long or short periods of time. For our study, we placed HOBOs in and around the building to collect this data. The HOBOs recorded data for a period of two weeks at 12 minute intervals. Within these two weeks, the outside conditions ranged from sunny to overcast skies, and temperatures ranged from mid 30s to high 70s. This was a very good combination of conditions for testing. After the test period was up, we downloaded the information and made charts to compare the data. From the data collected, we can tell if the building has excessive heat gain and heat loss.
Spot Pyranometer
The Spot Pyranometer is used to take surface temperatures of objects such as walls, floors, ceilings, and just about anything else. For our purpose, we took readings of the floor, walls, and ceiling. The reading were taken at three different times through out the day with various sky conditions. From the readings we were able to tell where the most heat gain was and also where heat was being lost.
Licor Meter–Pyranometer
The Licor Pyranometer is used to find out how much of the sun's radiation is penetrating the building through the glazing. With this device, we can tell what windows need to be better protected from the sun and how much heat the windows are letting in.
