10. Evaluate heat transfer and its relationship to home heat

Which of the following roofs would be the most effective at reducing energy

• albedo of .3 and thermal emittance of .3

• albedo of .6 and thermal emittance of .6

• albedo of .3 and thermal emittance of .6

• albedo of .6 and thermal emittance of .3

A roof with an Albedo of .7 would be a surface that is

• highly reflective and cooler

• highly absorptive and cooler

• poorly reflective and cooler

• highly reflective and hotter

The process whereby plants surrounding a home transport water into the atmosphere where it evaporates and cools the air is called

• evaporation

• condensation

• evapotranspiration

• transpiration

The arrangement of windows and doors on the elevations of a building is called

• solar gain

• fenestration

• albedo

• passive convection

Shading the fenestration of a house

• helps to control solar gain when extra heat is not needed

• is best when it is external shading.

• can include trees, awnings, and porch roofs

• all of these

Which of the following R-values is most effective at insulating against heat or cold transfers?

• R 13

• R 22

• R 38

• R 49

What can account for almost 50% of heating and cooling costs in a home?

• air leaks

• dirty filters

• lack of window blinds

• all of these combined account for half of heating costs

A passive method for keeping a home cool is

• using shade trees

• blinds for windows during the day

• venting hot air spaces

• all of these

Which passive cooling method uses a system of pipes that utilizes the constant subterranean temperature of the earth to heat or cool air/fluids within a structure

• solar chimney

• solar collector

• air conditioner

• ground tubes

Which of the following is not a passive cooling system?

• solar chimney

• thermal chimney

• air conditioning

• ground tubes
