Why don’t you do it first?

Yesterday I took time out from my writing work and went to the library to return 4 overdue books. The library was built quite recently and looks modern with a huge, maybe 10m high and 20m wide glass window on one side instead of a wall. It also houses a concert hall and training gym.
After I was complained about my overdue books a little more than I had expected, by a chubby gray-haired librarian with glasses perched on her nose over which she looked me in the eye and told me never to do this again, I went up the stairs to the lobby. I looked up the huge glass window again. A suspicion occurred to me. How much heat escapes from this window to the cold outside?? I walked closer to the window to check the glass. Very thin for its size. A single plate, not double. There seemed nothing at all designed to keep the cold out. Now I couldn't control my curiosity. I walked up to a receptionist girl and asked.
"Do you happen to know what the electric consumption of this building is?"
"Pardon?" she said.
"I would like to know how much electricity is used away in this building." I rephrased.
"Sorry, I have no idea." she said with a look that betrayed her "sorry".
So I went to the information desk and asked the same question to a girl in the same uniform sitting in front of the counter.
"I am very sorry, but such data is not available here. I'm not sure but there is a disaster control center downstairs. I think they control all the electricity so they may know it."
I went down stairs and asked over the window a man in a uniform of security guard.
"What?" he said.
I rephrased the same question again a bit more smoothly than before.
"Do you happen to know, by any chance, how much electricity is used in this building?"
He looked shocked as if he heard something he should not have heard. He went deeper in the office to a man in a green work clothing and whispered something to him. Then the green man came up to me and asked
"May I ask what you would like it for?"
"Well... I... I am doing a kind of research."
"What kind of research may I ask?"
"I am investigating energy consumption in public facilities." Trying to make it sound scientific.
"Are you with college? (大学関係の方ですか？）"
"Yes, actually I am, a kind of." I replied feeling a bit guilty because I am not.
"So in what form would you like to know? We very unfortunately do not have statistical data here."
"Oh, in that case, I would be more than happy if you let me know just for last month in the unit of kilo-watt-hour."
He went deeper in the room again and looking earnestly into a notebook and then came back and said very coldly. "310,000 last month."
"In kilo-Watt-hour?" I asked again. "Yes." very bluntly he said and went back inside before listening to my thank you.
On my way back I thought over this number again and again. This is an incredible number. When I came home I started to investigate about it on the Internet as usual, forgetting about the report I was writing. According to Tokyo electric power company, TEPCO, the average electricity consumption per household is 3,600 kwhr per year. Monthly consumption is 300 kwhr. So the 310,000 kwhr used by the library building amounts to the electricity used by 1000 households. Can you believe it? To maintain a supposedly cool facade with a huge window, it is a bit too much.
I heard that the government, growing impatient about sluggish progress of CO2 reduction, is discussing a sort of tax on houses with low energy efficiency. Before blaming citizens, why don't they start thinking about their own facilities?
