Before investing in the right technology for your building or portfolio, it’s important to understand how energy management systems and building automation systems are used in many buildings to improve operations and minimise energy spend. One thing we realised in our exchanges with hundreds of energy professionals is that the terms EMS and BMS / BAS are often used interchangeably, when in fact they are actually fundamentally different. To clear up the confusion, we put together this handy infographic.

Green building certifications are essential in meeting global climate targets, but here's the issue: certifications like BREEAM and LEED refer to the intended energy performance of a building, in the context of its design and construction stages. But happens once that building is occupied? The building’s energy performance on paper starts to look very different from the daily reality of its actual use. In fact, according to a RIBA CIBSE database, buildings tend to consume between 1.5 and 2.5 times the amount of energy originally predicted by their designers. That means even smart or green buildings on paper could be running inefficiently in practice - and costing you money. This discrepancy is called the energy performance gap, and our latest free guide is all about closing it using the combined powers of building automation technology and real-time energy analytics.

There are 6 variables that drive an occupant’s thermal comfort:
  • air temperature
  • surface temperature
  • humidity
  • clothing insulation
  • activity level (metabolic heat)
  • air velocity
The problem? These factors simply don’t tell the full story behind the maintenance involved in optimising temperature in office buildings, commercial buildings, primary schools or university campuses. Thermal comfort depends on other factors as well, like climate and occupant preferences – for example, occupants in Denmark may be more susceptible to humidity and heat levels than occupants in Portugal. The biggest challenges for Commissioning Agents and Facility Managers lie in finding a temperature which is satisfactory for the majority of their occupants, all who may have slightly different preferences, and doing so without sending the energy bill through the roof.
