LEED Gold Mercy Corps headquarters an international organization that helps people around the world survive and thrive after a crisis. The project was built in very close proximity to an active light rail line; in addition, it was imperative that the site remain clean and secure for the Saturday Market, held adjacent to the site on weekends. The initial design called for a very complicated and expensive curtain wall design on the East wall. Initial pricing was in the $1.8 million range. This system also had several shortcomings in terms of water resistance and thermal performance. By switching to a simpler system, the cost was reduced by $724,000 while the system’s water resistance and thermal performance was improved substantially.
