On filing for a building permit, a Leadership in Energy and Environmental Design or International Codes Council checklist will have to accompany the building application. A knowledgeable third party may “rate” the proposed project for expected performance. Before the interior finishes are applied, the building will be checked by a third party to see that established benchmarks are met. A final inspection verifies performance and other features called for in the drawings and specifications. The rating standards are practical and foster good design, specify energy-saving techniques and systems and reward the best, most efficient use of all resources. Documents filed at completion are reviewed by national organizations to determine level of achievement.
