Case study describing a zero energy ready home (ZERH) that was recently completed featuring an innovative wall system. This highly insulated (high-R) light-frame wall system, called the extended plate and beam (EP&B), is for use above grade in residential buildings. 

The Florida Solar Energy Center (FSEC) has completed a fourth year-long evaluation on residential hot water heating systems in a laboratory environment (east central Florida, hot-humid climate). This report contains a summary of research activities regarding the evaluation of two residential electric heat pump water heaters (HPWHs), a solar thermal system utilizing a polymer glazed absorber and a high efficiency natural gas system.

This case study presents a cold-climate project that examines an alternative approach to ground source heat pump (GSHP) ground loop design. The innovative ground loop design is an attempt to reduce the installed cost of the ground loop heat exchange portion of the system by containing the entire ground loop within the excavated location beneath the basement slab.

Tankless water heaters can deliver large quantities of hot water under changing load conditions and at a relatively constant temperature, like storage water heaters, but without suffering the standby loss (tank heat loss) of the storage water heaters.
