What is the difference in yearly cost savings between using re-glazed units and new aluminum windows?

The correct choice indicates that the difference in yearly cost savings between using re-glazed units and new aluminum windows is $1,200. This figure likely reflects an analysis of the operational and maintenance costs associated with each option.

When considering the financial performance of re-glazed units versus new aluminum windows, several factors come into play such as energy efficiency, durability, and potential maintenance costs over time. Re-glazing typically involves applying new glazing to existing frames, which can be more cost-effective upfront compared to purchasing new windows, but may not always provide the same level of energy efficiency or longevity as completely new installations.

By calculating the yearly cost savings, one can assess the long-term financial implications of each option. In this scenario, a difference of $1,200 suggests that re-glazing is a financially advantageous route compared to the installation of new aluminum windows over the course of a year, factoring in energy savings and other associated costs. Understanding the long-term view of these expenditures is crucial for making informed decisions in architectural projects.
