New Construction Builders Challenge: Sealed Attic and High Efficiency HVAC in Central Florida: A Year in Review Monitored Prototypes - Springwater Homes
In 2010 the Florida Solar Energy Center (FSEC), with funding from the Building America program, was involved with a new Builders Challenge builder located in Rockledge, Florida -- Springwater Homes (see figure 1). The newly constructed home in March 2010, features a sealed attic with R-27 roof deck insulation (shown in figure 2). Selection of the HVAC system, an important aspect to achieve high efficiency levels in buildings, ended with one of the highest residential equipment systems available in the U.S., the Nutone IQ Drive (SEER 21). The house was confirmed with a HERS index of 53 using the EnergyGauge simulation program. By April 2010, FSEC researchers had installed a variety of sensors and a data logger to investigate the power consumption of the mechanical HVAC equipment but most important the humidity characteristics inside the sealed attic.
