How BEMIS Can Help Optimize HVAC Efficiency and Save Money

Thu, Mar 03, 2016 @ 03:26 / by Jim Newman posted in HVAC, Retrofit, Energy Codes, energy efficiency, Energy Audit, Energy Use Index, building automation, BEMIS


In a recent study, The American Council for an Energy Efficient Economy (www.aceee.org) found that “Commercial buildings could save up to $60 billion if investments in energy efficiency were ramped up by just 1-4%.”

When I was interviewed a year and a half ago and posted this blog in advance of my talk at NFMT Vegas 2014, there weren’t many companies promoting, or providing, building energy management information systems. Building Energy Management Systems (BEMS) and Building Automation systems (BAS) were definitely part of the conversation, but there wasn’t much out there at that time about Building Energy Management Information Systems (BEMIS). Today they are becoming increasingly popular, and it’s easy to see why.

NREL_slide_75_crop.jpgA quality BEMIS will have a software-based front end that can run reports as well as conduct diagnostic testing and provide a clear picture of the building’s performance – through easy-to-understand visuals.  And today’s BEMIS does more than simply offer reports. It provides feedback, incorporating the tools and reporting capabilities from the BAS as well as fault detection, diagnostic tools and automated system optimization technologies.

ASHRAE bEQ Updates Include “As Designed” Rating for New Buildings

Tue, Apr 14, 2015 @ 10:48 / by Jim Newman posted in Codes & Standards, bEQ, Building Energy Quotient, Energy Codes, ASHRAE, Energy Audit


With more and more cities and states adopting Energy Use Index (EUI) requirements, the popularity of the ASHRAE Building Energy Quotient (bEQ) voluntary building energy labeling program has been growing. While independent of other rating systems, it actually complements those existing green building and energy rating and labeling programs.

LEED-Certified Buildings: Energy Efficient or Not?

Wed, Apr 09, 2014 @ 12:33 / by Jim Newman posted in Codes & Standards, Energy Codes, LEED Guidelines, LEED 2009, ASHRAE, USGBC, Green Building, LEED Cerified Buildings, LEED Certification, LEED Certified, Sustainability


Today's LEED certified buildings are more energy efficient than their predecessors.There has been some heated discussion lately about how much energy LEED® certified buildings use. When the US Green Building Council (USGBC) first came out with its Version 1 LEED Guideline in 2000, a building could earn LEED certification without any points in the energy section.

Energy Performance Disclosure/Energy Use Index – What Does it Mean?

What Does an EUI Mandate Mean to Facility Managers and Building Owners?

We have been hearing a lot lately about Energy Performance Disclosure and Reporting Mandates for public buildings, sometimes referred to as the Energy Use Index (EUI).

Six Reasons I Still Go to ASHRAE Conventions

Wed, Feb 13, 2013 @ 01:51 / by Jim Newman posted in HVAC, Codes & Standards, Energy Codes, ASHRAE, Sustainability, Energy Audit


I recently returned from the ASHRAE Annual Convention in Dallas (#ASHRAE, #Dallas2013). For me, ASHRAE conventions make it easy to keep up with new developments and new ideas in heating, cooling, ventilation, filtration, Standards and more. Since HVAC can amount to more than 70% of a building’s energy use, and I am an energy efficiency consultant, I need to stay on top of new ideas, codes, Standards and best practices.
