Architects are becoming increasingly interested in building designs that rely less on air conditioning and more on balancing thermal properties.
A
It is most efficient to plan and build affordable, low-energy housing units in 10- to 20-story blocks.
B
Post-planning is rare, which is unfortunate because it is effective in balancing the need for air conditioning.
C
Business and markets, rather than planning and design, are the main forces behind building development and the push for air conditioning.
D
The correct answer is C.
Explanation: This statement highlights that business and market demands often prioritize immediate development and cost-efficiency, leading to a reliance on air conditioning rather than focusing on sustainable building designs that balance thermal properties. While architects are interested in reducing reliance on air conditioning, external factors like market pressures can hinder innovative designs.
