Demonstrating leadership skills
By mentioning your experience leading multidisciplinary teams, you're showcasing your leadership and teamwork skills. It's one thing to excel at your job, but managing others effectively is a whole other ball game. This tells your employer that you're not just a great architect, but also a capable leader who can take charge of a project and guide a team towards successful completion.
Showcasing specialization and experience
When you highlight your specific area of expertise - here, sustainable design - and back it up with a solid experience record, you're telling potential employers two important things. First, that you have a niche skill set that could be of value to their firm. Second, that you've been practicing this skill for a significant amount of time, implying a level of mastery and reliability. It's a powerful combination that can visually distinguish your resume from a pile.
