IDEA:

1.Energy consumption of elevator

Because I live in a high rise, 48th floor. I need to take the elevator every time I go out or come home. At school I occasionally take the elevator and occasionally take the stairs. I want to count the energy I consume by taking the elevator in a week.

So I need to calculate 1. The energy required to run the elevator one floor 2. the energy required for the elevator buttons 3. the energy consumed by the floor display The units of these energy should be joules The problem is that I don't know how to measure these energy consumptions directly.

Process

Direct experience:

• What have you (or will you) measure? How? What were the results?
• Some domains have specific energy and power units (electron volts, tons-of-oil-equivalent, etc). What units are appropriate for your topic?

1. Calorie burning——Kcal

   I will use the smartwatch to record my consumption of climbing stairs. Although I've been climbing stairs for half a month, I haven't bought a watch yet (I'll buy now)

2. Electricity consumed by elevators——kwh

   I may not be able to measure the consumption of the elevator directly, but I will go to the relevant information to calculate this figure.

Context:

• What does Smil say about your subject (if anything)?

Chapter 3 Energy in human history

Chapter 5 Energy in everydaylife

• What does the IEA/EIA/UN/etc. say?
• What are other data sources you can use? Papers? Journals? The more specific to your topic the better.

One way to get a very rough ballpark figure would be to take the total energy used by a building’s elevators in a given workday and divide that by the number of tenants. At the request of the Green Lantern, a ThyssenKrupp consultant ran simulations for typical five-story, 16-story, and 42-story office buildings. In each case, the energy use per tenant came out to about 0.3 kWh. Is that a significant amount of energy? It’s about as much as you’d save in four hours by replacing an incandescent bulb with a CFL .

Most elevators stay on all day, even if there’s no one using them. The average standby power rating is between 0.8 and 2 kilowatts, which can really add up: Analysts at ThyssenKrupp who studied a 16-floor office building in Ohio found that roughly one-third of the elevator bank’s daily energy consumption occurred during nonbusiness hours. Keeping elevators well-lit is an issue, too: Bulbs might add 1,750 kWh a year per cab.
