Energy Systems Modeling and Design

Before you make changes to an existing facility, one should first assess what you have – to make sure it suits all your functional needs (function is always considered first), as well as your energy needs (reducing energy is considered after function). Once you understand present conditions, you can perform computer modeling to estimate savings from various energy reduction strategies, design the appropriate changes, followed finally by proper installation and implementation of the reduced energy building systems.

Loureiro has strong experience in this whole chain – from assessment, to modeling, to design, to implementation. Here are but some of the areas we have worked from start to finish:

• Lighting System Analysis and Evaluation (e.g., energy efficient lamps, occupancy sensors, building lighting timers, day lighting control)
• Compressed Air System Analysis and Design (demand, generation, and distribution)
• HVAC System Analysis and Design (overall and sub-system efficiencies)
• High and Low pressure Steam System Analysis and Design (demand, generation, and distribution).
• Process Ventilation Analysis and Design (Indoor Air Quality (IAQ), Demand Control Ventilation (DCV), Energy Efficient Heat Recovery (ERG), controlled make-up air)
• Incorporating LEED into new construction or existing building projects
• Mechanical-Electrical evaluations of utilities, power distribution, utility bills, ASHRAE 90.1 baseline comparison.
• Building Water Efficiency (Low flow fixtures, domestic hot water heating, Energy Policy Act of 1992)
  We can also assist with project bidding and installation, making us your one-stop energy systems change company.

Here is but a partial listing of software we use as we model municipal, industrial, commercial, and institutional facilities:

• Trane Trace - a very comprehensive whole building simulation program that complies with Appendix G for Performance Rating Method of ASHRAE Standard 90.1-2007 for LEED analysis. This program was also the first simulation software approved by the IRS for energy-savings certification under EPAct.
• Department of Energy’s (DOE) AirMaster +
• DOE MotorMaster+
• DOE Steam System Assessment Tool (SSAT)
• DOE Pump System Assessment Tool (PSAT)
