State government, healthcare (Concord Hospital), and granite quarrying heritage (the granite for the US Library of Congress came from Concord) shape the economy. Quality triple-pane Low-E systems reduce heating bills 25-35% versus original single-pane windows; they also improve sound dampening, reduce UV fading of furniture and floors, and add measurable resale value.
