KBA Presents: Lighting Controls Tech Session with Eric Trutsch

On May 4th Eric Trutsch presented a lighting controls tech session to the KBA team. Eric has over 15 years of experience with electrical low voltage and power systems, and has been a commissioning professional with KBA since 2014. His session was geared towards how to test interior lighting controls, to include occupancy and daylight harvesting. The following is a summary of the major types of interior occupancy sensors presented by Eric:

What are the major types of interior occupancy sensors?

1.      Passive Infrared (PIR)

a.      Detects a change in temperature when a person enters a room

b.      Detects major motion (across lines of detection and in line-of-sight to sensor)

2.      Ultrasonic

a.      Detects a frequency shift from emitted and reflected sound waves

b.      Detects minor motion, such as typing on a keyboard

c.      Motion does not need to be in line-of-sight

d.      Can be activated by ‘unintended motion’, e.g. duct noise

3.      Dual Technology

a.      Uses both PIR and Ultrasonic technologies

b.      Both technologies must be activated to turn the lights on

c.      Only one of the two technologies is required to keep the lights on

d.      Self-adaptive to automatically adjust sensitivity and timing

4.      Vacancy Sensors

a.      Lights must be manually turned on

b.      Lights are kept on by the occupancy sensor

c.      Required by Title 24

d.      Occupancy sensors can be used as vacancy sensors

e.      Vacancy sensors cannot be used as occupancy sensors

If you would like more information about testing lighting controls, don’t hesitate to give us a call! Eric, or another member of our technical team, will be happy to answer any questions you have.

Let's Talk Recommissioning

Did you know that the BCxA recommends recommissioning every 3-5 years, and in California recommissioning is required on all state buildings over 50,000 square-feet on a recurring 5-year cycle?

Recommissioning benefits include:

  • Higher appraised building values
  • Reduced operating expenses
  • A utilized O&M staff
  • Improved indoor environmental quality
  • Increased energy efficiency performance

For more information on recommissioning, check out our flyer:

KBA has 10 experienced CxA's ready to help with your recommissioning project. Contact us today for more information. 

KBA's Summer Celebration

This past weekend KBA employees and their families gathered for our annual summer party. Unusually for Seattle, temperatures reached a record high of 96 degrees making it a scorcher!

Hosted this year by Jeramy Bromley, everyone enjoyed a delicious taco bar whilst staying cool in the shade of the huge maple tree that shelters Jeramy’s back yard.

A great way to mark the start of summer and celebrate everyone’s hard work so far this year – well done KBA!

KBA Releases White Paper

KBA is excited to announce the release of our white paper titled, 'Commissioning School Projects; What's Working, What's Not?'

Paper Synopsis
'Over the past 20 years, Building Commissioning (Cx) has been increasingly applied as a quality assurance process to the construction of many public schools. Today it is common practice in many areas, and a code requirement in others. In Washington State for example, all buildings must be commissioned in order to comply with the state Energy Code, and since 2001, commissioning of school projects has been a requirement as part of a package that also mandates value engineering and constructability reviews. Now that numerous schools have been commissioned, and with commissioning in many areas commonplace, it is a good time to survey the various stake-holders regarding school commissioning's value and effectiveness. This paper reports on the results of such a survey and suggests ways in which we might improve our approach to school project commissioning.'
