Ensuring Central HPWH System Success

Central heat pump water heating (HPWH) systems are the cutting edge in all-electric multifamily buildings in California. These systems promise to significantly lower carbon emissions of buildings while reducing energy costs and providing the same satisfactory hot water delivery performance as gas systems. Accordingly, the California Energy Commission (CEC) has partnered with consultant Ecotope to create Title 24 prescriptive and performance compliance options enabling further market penetration. The groundwork is set for this to become a mainstream technology!

The Growing Features of Beyond Efficiency's Hot Water Distribution System Models

As I introduced in my previous article, we at Beyond Efficiency are in the process of developing simulation models for hot water distribution systems. We believe that these tools will support industry practitioners ranging from researchers to Title 24 consultants, to building designers, and everybody in between.

Introducing Beyond Efficiency’s New Hot Water Distribution Simulation Tools!

The built environment has a hot water distribution problem. There historically haven’t been any analytical tools available for hot water distribution systems. Utilities and states couldn’t compare different distribution system approaches and use that analysis to decide what systems to encourage and discourage. California’s Title 24 can’t reward builders for installing advanced, well-designed systems because there aren’t any models they can implement to let builders demonstrate that their systems perform well.
