In the context of building healthy homes, efficiency improvements target what main factors?

Efficiency improvements in the context of building healthy homes primarily focus on energy and resource use. The goal is to create homes that not only meet the needs of their occupants but also minimize environmental impact. This involves using materials, systems, and designs that reduce energy consumption and optimize the use of resources. This might include implementing energy-efficient appliances, better insulation, and sustainable building materials, which ultimately lead to lower utility bills and a reduced carbon footprint.

By prioritizing energy and resource efficiency, builders can enhance the overall livability and sustainability of homes. This focus also contributes to healthier indoor environments by often utilizing non-toxic materials and improving air quality through better ventilation systems. In contrast, while costs, timeframes, design, and capacity do play roles in home building, they do not encapsulate the broader objective of improving efficiency related to energy and resource use, which is central to creating healthy, sustainable living environments.
