Long Term Operation of Renewable Energy Building
Abstract
As part of a renewable energy
project, a building was designed and
constructed to demonstrate several
renewable energy technologies at the
Wind Test Center of the Alternative
Energy Institute (AEI). The systems
are passive and active heating,
solar hot water, daylighting,
passive cooling, and generation of
electricity from a 10 kW wind
turbine and 1.9 kW of photovoltaic
panels, each connected to the
utility grid through inverters.
Since 1991, 16,900 kWh have been
purchased and 31,300 kWh returned to
the utility grid. A significant
portion of the purchased power has
been used in charging our electric
van. The building does not have
auxiliary heating or cooling systems
powered by fossil fuels. A data
acquisition system monitors
building, exterior, and system
temperatures as well as power
outputs of the wind and PV systems.
The data are sampled at 1 Hz and
averaged each 15 minutes. Annual,
seasonal and diurnal patterns are
shown in graphical format.
Temperatures for the coldest days of
winter and hottest summer days are
also presented.
