HVAC

The use of high performance HVAC equipment can result in considerable energy, emissions, and cost savings (10%-40%). Whole building design coupled with an “extended comfort zone” can produce much greater savings (40%-70%). Extended comfort includes employing concepts such as providing warmer, but drier air using desiccant dehumidification in summer, or cooler air with warmer windows and warmer walls in winter. In addition, high-performance HVAC can provide increased user thermal comfort, and contribute to improved indoor environmental quality (IEQ).

HeatSpring instructors and courses are geared toward high efficiency systems and written for the leaders the industry.

Building & Powering an Award-Winning Net Zero Energy Home

Can a home be beautiful, powered entirely by solar energy, use sustainable heating and cooling systems and save it’s owners roughly $3,500 a year? Why, yes it can. Just ask Joanne Coons, who built her award winning, single-family, Net Zero Energy Home in 2010. Sustainable Woman Joanne talks Net Zero standards, efficient appliances and goods, her […]

Deep Boreholes in GSHP Systems: Pressure Considerations & Installation Practices

Factors such as space limitations are forcing engineers to utilize deep boreholes to meet design requirements for Ground Source Heat Pump (GSHP) systems.
In such cases, hydrostatic pressures must be considered to ensure successful installation can take place. This short course, led by expert Ryan Carda, P.E., focuses on the necessary calculations along with the recommended […]
