25 CHANGING THE SCHEDULE kw Red: Spring Break 2011 (March 28-April 02) 5am - 5pm Reduced Schedule Fri, Mar 25, 2011 Sat, Mar 26, 2011 Sun, Mar 27, 2011 Mon, Mar 28, 2011 Tue, Mar 29, 2011 Wed, Mar 30, 2011 Thu, Mar 31, 2011 Fri, Apr 01, 2011 Sat, Apr 02, 2011 Sun, Apr 03, 2011 Mon, Apr 04, 2011 Tue, Apr 05, :00 3:00 6:00 9:00 12:00 15:00 18:00 21:00 0:00 Spring break was used as a test Morning start was changed from 5am to 6am Evening shutdown was changed from 10pm to 5pm This saved $250/wk (or $13,000 per year) in fan electricity alone

26 COMMISSIONING A quality assurance process Occurs between early design phase through occupancy Ensures that the building operates as intended Building staff are prepared to operate and maintain Why is it needed? Increasing complexity of building control systems Lack of contractual coordination between trades Technical staff in the field who looks out for the owner Construction Manager Plumbing Mechanical Engineer Architect Electrical Engineer General Contractor Controls Engineer

27 ONGOING COMMISSIONING Requires a full-time energy watchdog Nights, weekends, holidays You can t turn things off when you aren t around Someone to put eyes on all the dampers, valves, VFDs, boilers, chillers, and plug loads Potential for 10-25% savings 31

28 RETRO-COMMISSIONING 32

29 TYPICAL FINDINGS FROM RCX Missing or broken equipment/components Incorrect thermostat settings and control sequences Incorrect or missing BAS schedules for fans, pumps, lights, and other key components Malfunctioning control sensors such as outside air temperature sensors, supply air temperature sensors, damper position, etc. Heating and cooling systems fighting each other (excessive reheat).

38 HIGH IMPACT NATURAL GAS EFFICIENCY HINGE Bonus Projects shall include the following functions: Projects may be an accumulation of energy saving measures all located within the same building but does not include facility wide improvements. Incentive and Allowable Percentage Adjustments: Projects that achieve savings of over 50,000 therms and less than 100,000 therms per year of natural gas savings will qualify for $3.50 per therm saved and up to 90 percent of Total Project Cost. Projects that achieve savings of over 100,000 therms per year of natural gas savings will qualify for $4.50 per therm saved and up to 90 percent of Total Project Cost. Projects must be a custom incentive and not currently listed as a standard incentive in the base Department of Commerce Standard and Custom Incentive Program. 42

39 HYBRID BOILER ECRM 4: Add a Condensing Boiler Supplement the two original boilers with a high efficiency modular condensing unit. This will run at peak efficiency during most of the low-load heating hours. ECRM 4 Annual Savings kwh kw therms Energy % $ Estimated Cost Add a Condensing Boiler ,632 9% $18,133 $50,000 Gas for heating $75,000/yr Full engineering analysis is necessary. Isolate the two old boilers with valves. AKA: Shoulder Boiler or Front-Loaded Boiler Full upgrade is always an option if funds allow.
