Use of simplified system models to measure retrofit energy savings Conference Paper uri icon

abstract

  • The retrofit of dual-duct constant volume systems (DDCV) with energy efficient variable air volume systems (VAV) has become common in recent years. In general, the energy savings from such retrofits are estimated by developing a temperature dependent regression model using whole building pre-retrofit energy consumption data. Model predictions are then compared with measured post-retrofit consumption, to determine the savings. In cases were the pre-retrofit energy consumption is not available such a method cannot be implemented. This paper describes a method that can be used to calculate savings in such cases. The method is based on use of a simplified calibrated system models.
