ECM No. 04.02 Outside Air Control and Economizers Buildings 3 Installed as part of ECM 22

ECM No. 04.07 DDC Controllers

Install DDC controllers on the energy management system as part of ECM 4.00.

ECM No. 04.13 Operational Enhancements Buildings 4 Installed as part of ECM 4.00.

ECM No. 05.04 Domestic Hot Water Heater Replacement

Replace existing domestic hot water heaters with new hot water heaters.

ECM No. 06.01 Sewer Conservation Buildings 1 Apply for sewer abatement for the cooling tower evaporative losses.

ECM No. 09.00 Variable Frequency Drives

Install VFDs on all new pumps and air handling units as part of ECM 22.

ECM No. 11.01 Vending misers Buildings 3,4 Add vending misers to vending machines.

ECM No. 14.01 Boiler Replacement

Replace boiler as part of ECM 21.04.

ECM No. 15.06 Cooling Tower Replacement and Upgrades Buildings 1 Install new cooling tower on existing dunnage.

ECM No. 19.00 Real-Time Metering Buildings 1, 2, 3, 4, 5 Install real-time metering at the main electrical service.

ECM No. 21.02 Renewable Energy Systems – Solar Thermal System Buildings 3 Installation of 16 evacuated tube solar thermal collectors on the roof of Building 3. The system should include solar thermal storage tank and connection to existing domestic hot water tanks in Building 3. System is expected to meet MassCEC grant eligibility requirements under the Com-monwealth Solar Hot Water program and should be capable of registering useful heat energy for Alternative Energy Credits as a Class I renewable energy system. Preliminary analysis has found that the Academic Building Lower Roof (Level 5) has an additional uniform load capacity of ap-proximately 8 pounds per square foot (psf), and approximately 15 psf for the concrete roof deck at the previous greenhouse location. The existing W18x40 beams along Grids 3.1 and 9.9 be-tween Grids F and G appear to control the uniform load capacity as they are subjected to drifting and sliding snow loads from the adjacent roofs. The existing roof framing may require reinforcing and/or supplemental framing based on the actual solar hot water framing configuration. The SER for the roof mounted solar hot water system shall apply the new solar hot water loads based on the actual framing configuration and verify the capacity of the existing roof framing. A summary of the proposed layout and the structural analysis shall be submitted to the owner for review. In-stallation of solar thermal collectors shall also be coordinated with other contractors for the re-moval of existing greenhouse and replacement of existing roof.

ECM No. 21.04 Renewable Energy Systems – Geothermal System Buildings 2, 3, 4, and Parking Lot #1 Installation of 120, 6-inch diameter by 500 feet deep, closed loop geothermal wells in Parking Lot #1. Scope of work includes trenching, piping, plumbing, monitoring systems, mechanical pump-ing and heat exchangers for complete ground source heat pump system for Buildings 2, 3, and 4.

Installed system is expected to register useful heat energy for Alternative Energy Credits as a Class I renewable energy system.

ECM No. 22.00 Air Handling Unit Replacement Buildings 1, 2, 3, 4 Replace existing air handling units.

ECM No. 22.00 Makeup Air Unit Replacement Buildings 3 Replace existing makeup air unit AHU-1.

ECM No. 22.00 Computer Room Cooling Unit Replacement

Replace existing units CRU-1 and CRU-2 in the Server Room.

ECM No. 22.00 Exhaust Fan Replacement
