7 Steps for Designing an Economical Net Zero Energy Residence and Tools to Help – Free CEU Webinar

Seven steps for transforming a conventional house to an economical, net zero energy home are presented. The energy and economic impacts of infiltration sealing, wall/roof insulation, windows, heat pumps, fresh air ventilation, water heating, appliances and solar photovoltaic systems are covered. An example 2000 square foot house is sequential transformed from conventional construction to high performance, coupled with the economic and financial (monthly payments) performance. The performance of solar powered electric vehicle (EV) are included with the presentation. ZEROs (Zero Energy Residence Optimization software) is used as the basis for the simulation results. ZEROs (see BuildEquinox.com/Zeros) is free-to-use, online software developed by Build Equinox that is used for modeling home performance throughout North America, Europe and Asia.

Lessons Learned

1) Understand energy and moisture flows required for maintaining a healthy home relative to house design, climate and occupant activities.
2) Learn how to find an economically optimal house design based on Life Cycle Costing.
3) Compare financing (monthly payments for mortgage, insurance, real estate taxes and energy) for a conventional home and a high performance, healthy, net zero energy home with solar powered transportation.
4) Develop an initial familiarity with ZEROs (Zero Energy Residential Optimization software) energy, IAQ (healthy environment), comfort, solar PV, economic, and financial simulation capabilities.
