Technical Committee: 6.1 Hydronic and Steam Equipment and Systems
The drive towards high performance buildings has seen energy standards continue to increase their minimum efficiency targets to hydronic equipment. This session explores the recent changes to Standard 90.1-2016 on efficiency targets of hydronic pumps and the upcoming U.S. DOE pump efficiency legislation. A look at the European Union efficiency legislation around hydronic pumping equipment and how they compare to North American levels is presented.
1 New Standards from ASHRAE and U.S. DOE for Commercial HVAC and Plumbing Pumps
This seminar outlines for both ASHRAE 90.1 -2016 and the Department of Energy – Energy Conservation Standard for Pumps, what these changes are and when they will effect the industry. The seminar comments on the implications of the changes to our industry from an energy conservation and cost stand point. Finally, the seminar suggests how these changes could ideally be applied.
2 Future Pump Performance Regulations in EU and USA
Huge energy savings can be achieved when using variable speed drives on pumps in variable flow systems. However most systems are still equipped with fixed speed pumps due to first cost. For this reason, pump performance regulations are about to be adopted in EU and USA. These regulations comprise the combined unit consisting of the pump, motor and VSD i.e. the Extended Product. Methodologies have been developed which rates the Extended Product according to the overall efficiency. This presentation gives an overview of these regulations and highlights the differences between the US and EU regulation.
