 Module
2, Model House with Building Material Experiments,
demonstrates how energy use in a house is
impacted by the selection of materials. This is a tabletop module, the
central part of which is a model of a house.
- The
walls of the house are made of an insulating material with proper
siding.
- The
left and right side each has a window. One window has
standard glazing, the other window has low-e glazing.
- The
roof of the house is composed of two removable layers. The
first layer is a thin wood or metal covering, the second layer is
insulated (foam board with protective coating on the
surface).
- A
small temperature sensor is installed inside the house to provide
temperature readings during experiments. A panel on the backboard of
the module displays the present temperature, and shows the recent
temperature history inside the house on a scale that clearly shows the
trend. A digital readout of the temperature is also provided.
- This
module also displays samples of standard and energy efficient building
materials that can be used at home or school.
Module
2 is designed so that students can see how temperatures inside
a
house are affected by the types of materials used in constructing the
house. For example, the model house has a
door so that a student can put her hand inside the house and feel heat
entering the house through the two types of windows. This
way, a person can feel for herself the difference in heat transmission
between standard glazing and low-e glazing. To verify that
the two lamps release the same amount of heat, a person can place her
hand outside the model house in front of each window.
