HVAC management
Facilities are served by many different kinds of heating, ventilating and air conditioning (HVAC) systems, both for human comfort and to meet processrequirements. HVAC systems are generally designed to compensate for heatloss and heat gain, to provide ventilation and control of temperatureand humidity.
An energy management program for an HVAC system should begin with anassessment of the established HVAC systems or getting the optimum design for the un-established systems to determine their type, functionand operating procedures.This assessment will help identify areas of energywaste and opportunities to improve efficiency.Since HVAC systems vary widely from plant to plant, performance improvementsand energy cost savings will also vary widely.
Three important factorsdetermine the energy use of an HVAC system:
• The required indoor thermal quality and air quality;
• The internal heat generation from lighting and equipment;
• The design and layout of the building.Our group can serve the following activities:
- Initiation of a project by owner or developer
- Organizing a design team
- Determining the design criteria and indoor environmental parameters
- Calculation of cooling and heating loads
- Selection of systems, subsystems, and their components
- Preparation of schematic layouts; sizing of piping and ductwork
- Preparation of contract documents: drawings and specifications
- Competitive biddings by various contractors; evaluation of bids; negotiations and modifications
- Advice on awarding of contract
- Monitoring, supervision, and inspection of installation; reviewing shop drawings
- Supervision of commissioning
- Modification of drawings to the as-built condition; preparation of the operation and maintenance
- Manual
- Handing over to the property management for operation
- Design the building management system (EBM).
