from the RP-1547 results, which is a theoretical approach to Standard 62.1-based CO2 demand controlled ventilation. * 1711-WS: "Advanced Sequences of Operation for HVAC Systems - Phase II Central Plants and Hydronic Systems." The second phase of RP1455 that includes chilled water and hot water plants and distribution systems. Conclusions It is expected that most DDC system manufacturers will preprogram the ASHRAE Guideline 36 sequences into their systems so that they can be used directly or easily adapted for most any HVAC system application. Therefore, the plugand-play benefits of configurable controllers are realized without sacrificing energy performance and occupant comfort. Guideline 36 is expected to be published in 2015 or early 2016. But that should not prevent the RP-1455 sequences from being used right now. They are currently available by downloading the RP-1455 reports from the ASHRAE website, or by downloading the review draft of Guideline 36 at http://gpc36.savemyenergy.com/. Engineers can duplicate some or all of the sequences in their control specifications. Manufacturers should also start programming the sequences into their systems right now in anticipation of their being specified by engineers and to gain an advantage over their competitors.
