At the risk of sounding like a dick, resources for "state-of-the-art lighting design, by space type, that go beyond (ASHRAE standard) efficiency levels" are called "Architectural Lighting Designers", and they can be found practicing this blend of art and science world-wide.
In all seriousness, lighting design efficiency can be boiled down to a couple of simple metrics such as LPD, but when it comes to really getting aggressive one must use caution to ensure that the other goals of lighting design are not compromised. Issues such as contrast, task illuminance, uniformity and (gasp!) aesthetics are all part of the equation, and cannot be fully understood by simply multiplying the number of luminaires in the space by their load. These other issues are a product of the luminaire distribution, the volume, and the materials within it. ASHRAE and the folks at PNNL do a good job of making sure that with each proposed LPD reduction in the standards, there are multiple ways to meet those goals, in terms of luminaire selection and layout. But when really pushing the boundaries, it takes a little bit of design and investigation to ensure that the lighting is serving the needs of the building occupants.
