prepare an energy audit report to complement the in-class energy audit activity. write a 2-page report (total) summarizing the findings of the activity for the class room and for your personal habits. In your report, emphasize the implications of energy audits.
1. Identify basic room statistics (2 point per footprint) 10
2a. List items that consume power and for each item listed, search for the power consumption of each item (10 points for min 10 items including the modes, 10 points for listing power for each item) 20
2b. Estimate how much each item is used, on a average daily, weekly, and yearly basis (5 points per each daily, weekly, yearly calculations) 15
3. Generate a yearly total electricity consumption value for each user. Report this value across various denominators (1 point each per footprint, volume, number of users for day, number of users per peak, 1 point for answering in kWh) 5
Part II: Improvement Analysis
1. Figure out how much the power consumption in the room costs per year, based on SRP’s EZ-3 plan. Compare this to SRP’s Time-Of-Use plan. (5 points per writing down EZ-3 hour and price data, 5 points per writing down Time-Of-Use hour and price data, 5 points for calculating power on both plans, 5 points for commenting on results) 20
2. Create a list of potential improvements (reductions in use) for the items you listed in your inventory. What improvements are the most significant (2 points per improvement at least 1 supply side and 1 demand side improvement) 10
3. Estimate how much each of these improvements (min. 5) would cost, how much energy it would save and what the payback period for that improvement would be. Report the total power and economic savings associated with the improvements. (5 points per completed item) 25
Part 1: Inventory
1. Record basic statistics for the room: footprint, volume, number of users from 8AM-1PM, 1PM-3PM, 3-6PM, 6-8PM and 8PM-8AM.
2. Utilizing the table below, list all the items that consume power. Do not forget non-obvious lights, fans and appliances that are built into the walls.
a. For each item, determine its power in various modes. An example is listed in the table (light on vs. light off). For many products power consumption will either be listed on the back as Watts (W) or as separate Voltage and Current values (V, A). Be sure to include phantom load! (If you do not know what this is, search Wikipedia.) (min. 10 total for credit, including various modes of operation)
b. Estimate how much each item is used on a average daily, weekly, and yearly basis, taking into account that different items might have different modes (charging, sleeping, off, on, etc.), or consume more power in different stages of operation. [Note: answer needs to be in kWh] Put all of this information into the table below.
Device Power Used (watts) Daily Use (hours) Weekly Use (hours) Yearly Use (hours) Yearly Energy Use (kWh)
Ex. CFL light (on)
Ex. CFL light (off)
3. Generate a yearly total electricity consumption value. Report this value across various denominators, such as footprint, volume, number of users for entire day and number of users for highest peak use time. [Note: answer needs to be in kWh]
Part II: Improvement Analysis
1. Figure out how much the power consumption in the room costs per year, based on SRP’s EZ-3 plan. Compare this to SRP’s Time-Of-Use plan. You need to obtain data on peak/non-peak hours and price/kWh for peak/non-peak hours for EACH plan. To do this, visit https://www.srpnet.com/prices/home/tod.aspx. Be sure to comment on the differences in cost between the two plans, if any exist.
2. Create a list of potential improvements (reductions in use) for the items you listed in your inventory. There should be a minimum of 2 improvements, 1 behavioral and 1 technological, but additional improvement suggestions are welcomed. Be sure to comment on the implementation 2 of these improvements.
3. Figure out how much each of these improvements would cost, how much energy it would save and what the payback period for that improvement would be. Report the total power and economic savings associated with the improvements. Be sure to comment on the feasibility of these improvements. Would you recommend one over the other or both?
