Abstract
There are provided coated articles that include two or more infrared (IR) reflecting layers (e.g., of or including NbZr, Nb, NiCr, NiCrMo, and/or a nitride thereof) sandwiched between at least dielectric layers, and/or a method of making the same. The coating may be designed so that the coated articles realize green glass side reflective coloration in combination with a low solar factor (SF) and/or a low solar heat gain coefficient (SHGC). Such coated articles may be used in the context of monolithic windows, insulating glass (IG) window units, laminated windows, and/or other suitable applications, and may optionally be heat treated (e.g., thermally tempered) in certain instances.

1-22. (canceled)
A coated article having green glass side reflective coloration and including a layer system supported by a glass substrate, the layer system comprising:
- a first dielectric layer comprising silicon nitride;
- a first infrared (IR) reflecting layer comprising metal nitride on the glass substrate over at least the first dielectric layer comprising silicon nitride;
- a second dielectric layer comprising silicon nitride on the glass substrate over at least the first dielectric layer comprising silicon nitride and the first IR reflecting layer comprising metal nitride;
- a second layer IR reflecting layer comprising metal nitride on the glass substrate over at least the second dielectric layer comprising silicon nitride;
- wherein the second dielectric layer comprising silicon nitride is located directly between and contacting the first and second IR reflecting layers;
- a third dielectric layer comprising silicon nitride on the glass substrate over at least the second IR reflecting layer comprising metal nitride;
- and
- wherein the coated article has no metallic infrared (IR) reflecting layer based on Ag and/or Au;
- wherein the coated article:
- has glass side/exterior reflective green coloration comprising a glass side/exterior a* value of from −4.0 to −16.0 and a glass side/exterior b* value of from +7.0 to −15.0;
- and (i) if measured monolithically has an SF value of no greater than 0.40 and an SHGC value of no greater than 0.42, and/or (ii) if an insulating glass (IG) window unit having two glass substrates has an SF value of no greater than 0.25 and an SHGC value of no greater than 0.27.
