1. The architectural classifications of passive heating systems -- direct gain, indirect gain, and isolated gain -- are based primarily upon:

(a) the relative proportions of shortwave to longwave radiation inherent in each system type

(b) the thermal efficiency of the systems

(c) the relationship of solar collector elements to the occupied building spaces

(d) the magnitude of design heat loss that the system can offset

 

2. Indirect gain passive heating systems include these common approaches:

(a) Trombe walls, water walls, and roof ponds

(b) Trombe walls, phase change walls, and sunspaces

(c) south-facing windows, clerestories, and skylights

(d) Trombe walls, water walls, and curtain walls

 

3. Thermal storage is a critical element of most passive heating systems:

(a) because solar heating is so powerful its effect must be spread out over time

(b) because the greatest need for heating usually occurs at night when there is no solar resource available

(c) because it is required in order to meet the latent heat loss requirements of most buildings

(d) because it is required by the Florida Building Code

 

4. In a properly designed isolated gain passive heating system:

(a) there will be no barrier between the sunspace and the main building

(b) the wall between the sunspace and the main building will be uninsulated masonry

(c) the wall between the sunspace and the main building will be an insulated construction [isolated gain]

(d) the sunspace will be used to grow exotic tropical plants

 

5. List two of the several "conditions" necessary for a climate control system to be honestly classified as a passive system:

(a) the system uses no purchased energy

(b) system components serve multiple purposes (a concrete floor is used for structural, architectural, and thermal reasons)

or ........ the system is so tightly integrated into the architectural whole that it can not be easily separated from the whole;

or ........ the design of the system will be primarily the responsibility of the architect (versus a consultant)
