Service and Maintenance: Extending the life of VAV units

 · Today''s VAV boxes and VAV valves require very much lower pressures to operate them with 20Pa being typical, which would show a significant energy saving over the original units. This saving (200 - 20 = 180Pa) related to a building of, say, 40,000m2 with an airflow of 15 litres/sec/m2 would achieve a reduction of 308,000kwh per annum, or in terms of CO2 emissions a staggering 132,440kg.
