3yron Courts - CT2 Addendums and Parking CO exhaust system Page 1; <br />~ <br />~ <br />~ <br />~ From: Byron Courts <br />~ To: Leonard Lodder <br />Date: Tue, Jun 8, 1999 4:13 PM <br />Subject: CT2 Addendums and Parking CO exhaust system <br />Craig gave me the info this afternoon. Thanks <br />Basement parking- Exhaust system. Can we ask PK and their Mechanical sub to VE the duct work? I still think that there is savings in shortening <br />the runs and making the changes that you mentioned under the TOD site. <br />Interface has selected constant volume fans that are run by time clock . <br />We have saved operating costs in our other properties by installing CO sensors and VFD fans. This allows the fan horse power to be set for the <br />actual CO concent~ation . <br />At the bank of California this change had a payback of 2.and'/z years. Can we ask PK to VE this change and develop the energy savings <br />numbers? <br />Please let me know what you think. Byron <br />CC: Craig Lewis <br />
