Retro and on-going commissioning tool applied to an existing building: Operability and results of IPMVP

摘要: The new building thermal regulations, mainly published to reduce greenhouse gases emissions, leads a continuous improvement of envelopes. On the other hand, technical performance air-conditioning plants, ensured by commissioning procedures, becomes key point for control energy needs in buildings. essential work Annex 40 International Agency Energy reports on “Commissioning Building HVAC systems Improved Performance”. In this annex, test IPMVP, Performance Measurement and Verification Protocol, which is significant commonly used tool, carried out among many others. This paper aims present detail methodology IPMVP application results four different calculation options applied an existing equipped with innovative device, where outdoor airflow rate controlled indoor CO2 rate. provides helpful advice service company determine most adequate option terms accuracy, cost speed execution according available parameters (measurements, software) saving measure.
