B&G VRF whitepaper

HVAC system design requires methodical assessment of the options. Engineers must evaluate safety, costs, efficiency of VRF versus hydronics

With heating and cooling among the largest costs in commercial buildings, HVAC system selection is an important component in both new construction and retro t projects to keep costs in line and realize energy-efficiency targets. Hydronic systems provide water-based heating and cooling, a proven, cost-effective and sustainable medium.


PLEV Whitepaper

Bell & Gossett introduces new hydronic pump
selection criteria to maximize system efficiency Presented by: Xylem Applied Water Systems

This paper explains the importance of using B&G’s Part Load Efficiency Value (PLEV) calculation when selecting centrifugal pumps for hydronic systems.



imageHydronic systems: Technologically advanced and highly efficient In head-to-head comparisons, hydronics outperform VRF systems

This paper explores the operational performance and efficiency differences between variable refrigerant flow (VRF) HVAC systems and geothermal/hydronic pumping HVAC systems.




How to read a pump performance curve 

White Paper Series: Part 1 – How to read a pump performance curve Presented by: Xylem Applied Water Systems Understanding how to read a pump curve is critical in selecting the right pump for an HVAC or water system in a commercial building. Selecting the right centrifugal pump for the facility will, in turn, maximize pump




Pump cavitation and how to avoid it »

Pump cavitation and how to avoid it Best practices in pump system design Presented by: Xylem Applied Water Systems Cavitation is not a new phenomenon that can impact a pump system, but it is an issue that is growing. While no official figures exist, it is not misleading to say that in the last five




A Systems Approach to Energy and Water Efficiency in Commercial Buildings »

As the complexity of building systems continues to increase, the challenge of designing, installing and operating these systems also increases. New building codes continue to raise efficiency standards for new and existing buildings; economic conditions pressure organizations to cut energy costs wherever possible; and new corporate sustainability initiatives require steady efficiency improvements.



Efficiency Island Technical Review »

Presented by: Xylem Applied Water Systems Pumps that perform at a best efficiency point are becoming a thing of the past. Why operate at a single point when you can experience optimal efficiency across an entire island? This white paper introduces the concept of Efficiency Island and reveals how pump efficiency in HVAC systems can
