True or False: Saving Energy in the Workplace Automatically Drives Productivity

Bob Best

Short answer: False. Corporate sustainability programs often have a halo effect, perpetuating the myth that green initiatives inherently improve employee engagement. But not all sustainability measures are created equal when it comes to employee impact. Energy savings drawn from reduced heating or cooling requirements can be offset, for example, when employees are too hot or   …Continue Reading

Protect School Air Quality During Energy Efficiency Retrofits, Says EPA

Linda Hardesty

The US Environmental Protection Agency (EPA) released new guidance to help school districts protect indoor air quality while they conduct energy efficiency upgrades. These renovation and construction activities can create dust, introduce new contaminants and contaminant pathways, create or aggravate moisture problems, and result in inadequate ventilation in occupied spaces. EPA’s Energy Savings Plus Health:   …Continue Reading

‘Supercharger’ Makes Heat Pumps Viable for Cold Climes

Linda Hardesty

The US Department of Energy says up until now, heat pumps have only been popular in more mild, Southern regions, and have failed to gain traction in cold climates. This is because as air temperatures drop, air source heat pump performance suffers. However, the DOE has been working with Mechanical Solutions (MSI), a small business   …Continue Reading

DOE Wants 75% Increase in LED Lumens per Watt

Linda Hardesty

The US Energy Department is offering $10 million to support research, development and manufacturing of solid-state lighting (SSL) technologies, both LED and OLED. Today, available LED technology is about 150 lumens per watt; DOE’s target is 250 lumens per watt – a 75 percent increase. The funding opportunity is open to applications in the following   …Continue Reading

4 Guidelines When Designing for Net-Zero Energy

Linda Hardesty

When designing a net-zero energy building that produces all of its own renewable energy onsite, there are four points to consider, according to an article in Autodesk’s blog Line/Shape/Space. 1. Clearly express the end goal from the beginning and make sure all stakeholders are on-board with the energy-performance target. It should be included in all   …Continue Reading

McKinstry Conducts $10M Energy Efficiency Project for CU-Boulder

Linda Hardesty

McKinstry is conducting an energy efficiency project for the University of Colorado Boulder that will save the university an estimated $573,000 annually. Construction of the project began in September and addresses updates to the MacAllister Building. A technical energy audit performed by McKinstry in early 2014 revealed several opportunities for energy saving measures, including new   …Continue Reading

Amano is a member of Aledia’s Scientific Advisory Board. Aledia is a developer of next-generation LEDs based on its WireLED nanowire   …Continue Reading

Optimization Strategies for the Chiller Plant

Eric Erpenbeck

Healthcare, commercial, and institutional facilities often use a chiller plant to provide chilled water for air conditioning. It should come as no surprise that chilled water generation is a major contributor to a facility’s utility costs. Organizations are well served to seek ways to optimize their facilities for the best possible performance and energy usage,   …Continue Reading
