DFW Solar Home Tour 2012

Irving West Library
Tour Hours 10am-4pm

Texas’ First LEED Certified, Net Zero Energy Library: When applied to a home or commercial building, net zero energy means that the building generates as much electricity as it consumes on an annual basis.

Solar PV
kW: 346
Installation date: April 7, 2011
Installer: Applied Solar LLC (http://www.appliedsolar.net/)
Equipment: 1,444 SolarWorld 240 watt panels, PV Powered 75 kW inverter, PV Powered 260 kW inverter, Wattsun
AZ225 tracker, 12 Enphase D380 microinverters.

Electric Vehicle (EV) Friendly
Charging Stations including two Level 2 charging stations (these are Blink stations). The other EV charging is Level 1. They are all powered by renewable energy.

Host Comments:

Solar: The city received a $1.1 million grant from the Texas State Energy Conservation Office to offset
the solar system installation. A kiosk in the entryway will show how much electricity is being generated through
the solar panels, and there will be times when the library will be putting electricity back into the energy grid.
Renewable Energy – The library’s renewable energy systems include 144 geothermal wells for heating and
cooling; 1,444 solar power panels mounted as part of covered parking will generate electricity to run the
building. The geothermal system will provide an estimated $60,000 savings in annual energy costs, compared to a
traditional heating, ventilating and air conditioning system.

Green Building: Not only is the West Irving Library equipped with the latest in technology, its construction and design incorporate the latest in green building techniques such as drought tolerant landscaping and electric car charging stations. The library has many components that contain recycled materials such as its roof decking and structural steel. The ceiling tiles and carpet also contain recycled materials. In addition, more than 75 percent of the construction waste was recycled and very little waste was sent to the landfill. This net zero energy library has many environmentally friendly stories to tell that distinguish it from every other facility in Texas.

Daylight Harvesting: The north facing walls have large windows to allow maximum daylight to penetrate the building. The use of natural daylight will reduce energy costs.
