The document summarizes the Rowland Hall HVAC retrofit project. It will involve converting the building from a constant air volume (CAV) system to a variable air volume (VAV) system, upgrading existing equipment, and installing new controls. The project team is listed, along with phases of the work, potential disruptions, safety procedures, and contacts for issues. The retrofit is expected to improve energy efficiency by at least 15% compared to the old pneumatic system.

3. The W’s What Conversion from CAV to VAV Installation of Phoenix Valves Upgrade of existing Phoenix Valves Installation of VAV boxes Installation of Occupancy Sensors Conversion from Pneumatic Control to DDC ● Installation of new thermostats ● Installation of new electric actuators Sold-state sensors and controllers used in DDC systems have considerable energy-efficiency advantages over conventional pneumatic systems. Substantial advantages are realized in calibration and maintenance, but the critical value lies in the accuracy and reliability of the DDC systems. These features can yield operational energy savings of 15% and greater when compared to the conventional pneumatic system. The inherently precise positioning of valves and dampers with EMCS control loops and blocks are responsible for these energy savings.

4. The W’s Why The air handlers and exhaust fans are running at their mechanical limits. System is sized for VAV in a CAV building Fan motors failing prematurely Mixing boxes are 40 years old Risk Avoidance Scheduled Replacement will be much shorter and a comprehensive plan can be developed. Emergency Repairs will take longer, leave us open to further failures and provide no time to plan.

5. The W’s When 24/7 365 we know there is no good time We are here to work with you Starting now through July-2010 Where Unfortunately everywhere Offices, labs, classrooms, etc

6. How? Phase 1 – Abatement and Duct Cleaning The contractor will put up containment, complete abatement activities, remove containment, perform a final cleaning. You may be out of your office or lab for up to 3 days. Majority of this work will take place over the Holiday period from 12/12/2009 – 1/4/2010 Phase 2 – Construction You will receive a notice that construction activities are going to begin in 2 weeks. Your lab and office will not be closed but ladders and equipment will be in the way. Some areas may be inaccessible during this time. Supply and exhaust will be shut down at various times during their activities. Each fume hood will need to be emptied of any materials being stored in it. The hoods will be retrofitted with sash position sensors and stainless steel covers over the bypass. Phase 3 – Final Air Balance We will return to each area for a final air balance to make sure the system is functioning properly. This is expected to take place in July of 2010.

7. EH&S EH&S will oversee the project and perform field assessments which includes the following Assist in asbestos abatement specifications. Collect background air samples. Air monitoring during abatement work activities. Conduct work site visits. Perform clearance air monitoring.

8. Los Angeles Air Conditioning, Inc. At Los Angeles Air Conditioning we specialize in replacing worn out inefficient equipment! We have completed a number of projects on campus and look forward to working with all of you on this one. We have been in business for 50 years, and pride ourselves on being: Efficient - well managed / scheduled / coordinated considerate of our surroundings knowledgeable

9. Building Security If you see something out of the ordinary question it! Contractors will be working in all areas but have no reason to open cabinets, desks, or lockers. UCI staff carry ID and trades support wear blue shirts with their trade and name on their shirt

10. Adapting to your input! Facilities has added full duct cleaning to the project in response to the concerns raised during the last construction project. Noise Although not anticipated the contractor is aware that noise from construction may become an issue to both teaching and research being conducted in the building. Should the contractor be required to cease work for the class period or day, work will be moved to night or weekend to complete that area. There will not be extensive hammering; however the occasional need to affix anchors may require a roto-hammer be used. Outages No electrical, water, gas, or vacuum outages are anticipated. There is a possibility of HVAC outages and air imbalances throughout the construction process. Occupants experiencing trouble with fume hood ventilation, or too hot/cold calls will be provided contact information both via a building wide email and signs posted throughout the building.

11. How you can help us! When you receive notice that your office or lab is scheduled for abatement or construction activities. Clear off desk and counter tops the best you can. Secure personal belongings If your thermostat is covered we may need to talk about rearranging. If you encounter a problem with fume hood alarms, too hot/cold, etc please call Matt Gudorf @ 949-241-2360 I will interface with the contractor to resolve the problem or let you know when activities will return to normal. If you encounter water leaks, bathroom problems, lights not working, etc please call the service desk at 949-824-5444
