Existing Buildings

Existing building systems are constantly changing, bringing forth new issues that impact comfort, energy efficiency, and indoor air quality. Building energy audits, existing building commissioning, measurement & verification, and ongoing commissioning offer opportunities to save money, finance capital needs, and increase building valuation – all while improving the health, comfort, and productivity of building users.
