Net-Zero


New US Trends in Facilities Mechanical Engineering
  • Renewable energy and net-zero buildings.
  • Re-use/recycle energy that is disgarded.
  • Variable frequency drives/energy systems and multiple smaller HVAC devices to replace larger ones.
  • Super insulated envelopes and ASHRAE Standard 90.1.
Large Facility Energy Management
  • Benefits of renewable energy price stability over investing in a natural gas CHP system.
  • Benefits of eliminating a steam system used to heat one or many buildings.
  • Benefits of eliminating pneumatic controls and replacing them with a modern DDC system.
  • Energy recovery at a central chiller plant to reduce a simultaneous heating load.
  • Energy recovery at building level to reduce a cooling or heating cost.
  1. We show any facility state of the art lighting technology and controls to reduce energy use related to lighting. A lighting efficiency upgrade is the first energy saving affordable technology for any facility to do first.
  2. Plug in power loads: Controlling plug in loads with smart power strips that turns equipment off when not in use or by computer software.
  3. Super performing thermal envelope. We show any facility where to insulate and air seal from ASRAE data to achieve a maximum return on investment.
  4. Natural Ventilation verses controlled mechanical ventilation. Our company will explain how retrofitting a CAV system with a DDC system that controls an economizer, VFD’S and zone VAV’S. The new 2007 ASHRAE energy codes are designed to save facilities more energy than the 2004 ASHRAE energy codes.
  5. High efficiency HVAC systems. We show your facility some of the many ways how to improve the efficiency of your existing HVAC systems. One example is multiple ceiling mounted radiant heating units in warehouses or buildings with a high ceiling as opposed to using convection units. Another example is multistage compressors and VRF high efficiency AC units.
  6. Passive solar heating and cooling. We show your facility how to implement passive solar thermal heating during the winter months. Passive solar cooling is a white roof.
Natural Ventilation vs Controlled Mechanical Ventilation

Energy savings from demand mechanical ventilation and natural building ventilation as opposed to uncontrolled constant mechanical ventilation. Our company will explain how retrofitting a CAV system with a DDC system that controls an economizer, VFD’S and zone VAV’S (reduces energy consumption). The new 2007 ASHRAE energy codes are designed to save facilities more energy than the 2004 ASHRAE energy codes. Kitchens, walk in freezers and coolers in commercial buildings consume large amounts of energy and our company can show you how to make drastic reductions in their energy use.
