Renaissance architecture has had a big impact on modern buildings in many ways. Here are some important points to think about:

1. Symmetry and Proportion:

   • Renaissance architects focused on balance and harmony, which were inspired by ancient designs.
   • Many skyscrapers we see today often use these same ideas and look symmetrical.
   • A special concept called the Golden Ratio, about $1.618$, came from the Renaissance. This number helps create attractive designs in buildings today.

2. Columns and Arches:

   • A lot of modern buildings use classical columns and arches that go back to Renaissance styles.
   • You can see Corinthian, Doric, and Ionic columns in important buildings like the U.S. Capitol, built in 1800.
   • In a survey from 2018, about 45% of new public buildings in the U.S. included classical designs inspired by the Renaissance.

3. Use of Domes:

   • The dome of St. Peter’s Basilica, created by Michelangelo, set a standard for beautiful dome designs.
   • Today, many buildings use domes not just for looks but also for their purpose, especially in places like museums and city halls.
   • About 30% of civic buildings today have domes that take inspiration from Renaissance architecture.

4. Materials and Techniques:

   • Renaissance builders liked using strong materials like marble and brick.
   • Modern buildings still use these materials to make them last longer and look better.
   • The use of glass in today's buildings also relates back to the Renaissance, which emphasized large windows to let in light and create open spaces.

5. Cultural Legacy:

   • The Renaissance was important for developing ideas that focus on people and community.
   • Buildings designed with public spaces in mind are being used more now, with a rise of over 60% in urban areas since the late 20th century.

In conclusion, Renaissance architecture has made a lasting mark on modern buildings. Its influence can be seen in design ideas, the materials used, and the way buildings engage with communities.
