Scope Of Work
Lopez Engineering, Inc. (LEI) evaluated the existing condition of the heating, ventilating, and air conditioning system (HVAC) at the Department of Energy NNSA-SC facility 20381 in Albuquerque, New Mexico.
The evaluation resulted in the retrofit design of the HVAC system. Design deliverables included, a specifications package, as built project drawings, cost benefit analysis, and special reports. LEI performed the feasibility study, prepared the construction drawings, and performed construction management. Phase I of the project is complete with Phase II scheduled to begin in 2005. Phase I retrofit design encompassed demolition of old HVAC units and installation of new outside air handling unit with hot and chilled water cooling coils, ventilation ductwork, booster pumps where required and VFDs for supply/exhaust fans. New exhaust fans and related ductwork were also installed. A new open protocol DDC energy management system was specified to control the HVAC system.
Phase II of design included installation of ceiling mounted fan coil units in areas of deficient temperature control and ventilation. Fan coil units were connected to the air supply installation from Phase I. A new T-bar ceiling with new energy efficient lighting fixtures were specified to replace inefficient lighting. Modifications to existing fire protection and public address speakers were made to accommodate the new ceiling.
