Are Hidden Energy Losses Costing You?

Posted on Monday, May 16, 2016 in @ Home, @ Municipalities, @ Work

Are Hidden Energy Losses Costing You? Key Points Leaky ducts, failed steam traps and poorly-tuned controls can increase heating and cooling loads. Phantom load and personal appliances waste electricity and reduce overall energy efficiency. With a little investigation, you’ll likely discover these and other hidden sources of energy waste. When it comes to improving energy…

Getting in Tune with LEDs

Posted on Monday, April 11, 2016 in @ Home

Getting in Tune with LEDs Key Points Color-tunable LEDs can deliver light in color temperatures ranging from warm to cool. Correlated color temperature (CCT) measures the color temperature of the light emitted from a bulb. Three types of color-tunable products are available: dim-to-warm, white-tuning and full-color tuning. LEDs are well known for their efficiency, long-life,…
