Narrative:

We taxied out for a max gross take off weight; completed all check lists and all systems were normal. On take off I called for N1; auto throttle did not engage; the first officer advanced throttles to take off power and hit the N1 several times to try to get the map to update. After takeoff called for LNAV at 1;000 ft. Called for center autopilot but it would not engage; called for climb power and VNAV would not work without auto throttles; then called for flaps up. After flaps came up; we got the eec illuminated. I had the first officer; who is a training center instructor; run the QRH for the left eec. While running the QRH; we got a call from a flight attendant and were told that the cabin was extremely hot. Within two or three minutes we received 3-5 calls from the cabin reporting the heat. We then realized we had no control over the cabin temperature. On the last call from the flight attendants they stated the emergency exit lights were illuminating in the back. We told approach that we were returning and declaring an emergency. The relief pilot informed the flight attendants we were returning and to prepare the cabin. We discussed we might have a bus failure. The relief pilot and first officer at different times both checked for circuit breakers below the relief pilot panel. The relief pilot even moved his bags and flight kit for a second look. The first officer ran the QRH check list for an overweight landing and we accomplished all normal check lists. Briefing the approach; we found that the auto brakes and speed brakes would not arm. Made overweight landing on the runway; and while taxing back to the gate we started getting control of the air conditioning system. While at the gate in the aircraft; I used my cell phone and called dispatch and maintenance control and discussed in length the problems we had. At the same time we had station maintenance in the cockpit for a discussion in length of the problems we had. We entered all problems in log book and returned to hotel.
