1. (60 points) A facility is located in Oklahoma City, OK. The natural gas consumption from May-15 to Apr- 16 for the facility is given in the table below. Month MMBtu Consumption Energy Cost May-15 721 $5,004 June-15 325 $2,182 July-15 436 $2,896 August-15 342 $2,276 September-15 304 $1,906 October-15 317 $2,011 November-15 854 $5,182 December-15 1,346 $9,156 January-16 2,054 $13,743 February-16 3,143 $19,842 March-16 2,779 $18,981 April-16 1,524 $9,862 The production area of the facility is 250,000 sq. ft. and the average roof height is 35 feet inside the production area. The office area measures 50,000 sq. ft. The facility is air conditioned with four rooftop package units. A list of these units is given below. The maintained temperatures in the office area are 70 F and 75F in winter and summer respectively. During winters, the production area is heated by 15 forced-air unit heaters. These heaters are used very rarely and manually controlled by employees. The facility has many CNC machines in the production area, thus the environment is oily. The area also has frequent hail storms.

The average natural gas cost is $5.45/MMBtu. Production area operates 2 shifts of 8 hours each (from 6 am to 10 pm) a day, whereas office area operates 8 hours (from 8 am to 4 pm) per day. The facility operates 5 days per week, 52 weeks per year. Deliverables: A. List at least five possible recommendations that could be made for the facility based on the description above. B Write the Recommended Action section for each response to part 1. C. Calculate energy and dollar savings for only one recommendation you identified in part 1. Show calculations similar to that done in the example assessment recommendations (ARs). See AR examples in CANVAS, Module 13, third line. 1. (60 points) A facility is located in Oklahoma City, OK.
