Architectural engineers have the artistic vision to understand what an architect is trying to accomplish, and they use their specialized engineering skills to build structures that are durable, economical, and healthy. They are the 'master builders' and thus are indispensable members of the design team: Architectural engineers analyze the site, building orientation, and exposure; design the heating, cooling, lighting, and power distribution systems; ensure fire protection; and determine how water and waste will be managed.
