Heat the building OD Support the weight of the building QUESTION 2 Assuming that a foundation is well constructed to perform its structural role, which is a building performance problem that can occur with an improperly designed and constructed building foundation? OA. Energy loss O B. Moisture infiltration Excessive resource consumption D. All of the above QUESTION 3 What building common building material is typically used to minimize heat transfer through a building foundation? O A. Caullk O B. Heat tape O C. Infiltration D. Insulation

Explanation / Answer

Q.1 (D)

Purpose of the building foundation is to support the building by transferring the loads from the building to the soil in a safe manner.

Q.2 (D)

The improper design is a design which is not optimum for the requirements. So if a foundation allows energy transfer, then there are energy losses. If it is overly designed for the loads, then it increases the cost. If not insulated against moisture, then there may be moisture infiltration.

Q.3 (D)

Insulators are needed to control the thermal environment inside a building. Air is the cheapest thermal insulator, so a low-density material with low conductivity is used. Foam plastic and glass fiber batts are the most common materials used.

Q.4. (C)

Fly ash can be replaced up to a certain percentage because it has the cementing properties in the presence of lime. Also, it increases the workability.
