With regards to the first part of your question, yes, there is a strategy for the selection of the sites for Hindu Temples that involves vastu shatra (more information) which describes the theoretical flow of energy on the basis of vaastu purusha. Sites for temples themselves are selected on the the local geography and specifically "near water, in forests and gardens, on mountaintops and in valleys, and especially in caves" which are believed to be places where the gods play and are happy.
With regards to the second part of the question, I couldn't find anything in peer reviewed journals as to the validity of the claims that there is any "energy" actually being manipulated. Doing a journal search I was able to find results on vastu shatra from the stand point of architecture, anthropological studies, or religion. There is a chance that there might be some research that has been published in a foreign language journal, but most likely the primary sources of discussion of the energies involved are going to be religious or spiritual texts or discussions about Hindu architecture.
One thing to note on my read is that this appears to be fairly new from the Western society standpoint at large when compared other systems such as feng shui so there is a chance that there hasn't been enough interest in it to do a proper analysis as well in the same way that you can find research into the feng shui.
