Methodology

Hypothesis

This experiment seeks to look at the relationship between a green wall and its surroundings. In this experiment we will be testing how a green wall effects CO2, temperature, and humidity in a building in relation to the outside of the building. We believe that the green wall will help to lower CO2, temperature, and humidity in a building. We believe it will lower CO2 because it is an essential part to photosynthesis in plants and it will help to reduce temperature and humidity because it will help create a cooling effect due to evaporation. Along with the green wall we will be testing two different wall panels: Wood and Concrete. We will be looking out how well the material works with the green wall and we believe that the wood panel will work better with the green wall because it is an organic material and is used in sustainable design because of its ability to filter carbon out of the air (carbon sequestration). 

Preconditioning

  1. Establish a place of testing, pick somewhere that you can adjust the overall room temperature and also make sure the box isn't being direct hit by sunlight.
  2. Power on and make sure the Arduino Uno is reading for the DHT11 Temperature and Humidity Sensor & PM2.5 Air Quality Sensor
  3. Conduct a 1 minute experiment, making sure that the readings you are receiving from the sensors are at a consistent level.
  4. If the external and internal temperatures are a few degrees off, let the box sit for a few minutes, and repeat step 3.
  5. Make a general condition that you will use for every one of your experiments, ie. have both the inside and outside of the box be at 70°F / 21°C
  6. Once both the internal and external data read the same, attach the wall panel which holds and separates the green wall to the material we are testing.

First Test

The first test will be the baseline of the changes of the conditions throughout the day.
  1. Upon completing the preconditioning of the box, our first test will simply be an empty box with nothing attached.
  2. Let the box sit for 12 hours with the Arduino Uno controls on reading.
  3. Collect and compile the results from the various Arduino Uno readings.

Subsequent Tests

Here is when we put the green wall on to spot the effects it has in the interior and maybe exterior space of the box. We'll conduct an experiment that hosts just the green wall to compare it to the first test we did without any green wall.
  1. ​Complete the preconditioning of the box.
  2. We will attach the green wall by itself to the wall panel and then onto the box.
  3. Let the box sit for 12 hours with the Arduino Uno controls on reading.
  4. Collect and compile the results from the various Arduino Uno readings.
  5. When ready to do another test, repeat steps 1-4. Difference being instead of simply the green wall, attach the material to the wall panel as well.
