Improvements to cooling systems are one of the most effective ways to increase your bottom line and meet sustainability goals, especially if your building requires a lot of cooling. Schools, data centers, offices, clinics, warehouse/distribution centers and others can make great candidates for capturing the...
We often speak of new construction commissioning as a quality assurance process for new buildings, beginning from conception and design and continuing through construction and into initial occupancy. Some see it merely as a necessity for obtaining LEED points and complying with energy code. Others...
A client recently asked my opinion on power over ethernet (POE) and DC microgrids for their next building upgrade project. They received a hard sales pitch on POE lighting and controls and wanted some rational counterpoints. Here’s my two cents, after talking to a folks...
As an energy efficiency consultant, my primary job is to recommend energy projects to my clients. More often than not, they base their decision to implement the project on its cost-effectiveness. For energy retrofit projects, establishing payback is fairly easy – the project costs $X,...
In heating, ventilation and air conditioning (HVAC) systems, airflow reported at the variable air volume (VAV) box is actually a measure of total pressure. It gets converted into an airflow by a multiplier that is generated during testing, adjusting and balancing (TAB). This multiplier is...
We don’t usually do consumer product reviews here at kW. But I have to admit that, I love my new Costco/Koda LED ceiling fixture so much I’m making an exception. Why? Because it is the perfect hallway lighting fixture for my home, and so far,...
The next milestone in Assembly Bill 802 (AB 802) reporting is here. Last year was the first year the legislation took effect, requiring building energy benchmarking for many buildings in California. Another year in expands the population of buildings now required to benchmark. In addition,...
As trade tensions continue to escalate between the United States and China, the lighting industry can’t help but be impacted. Most of the big brand lighting manufacturers headquartered in the United States manufacture vast swaths of their lighting products offshore. So it’s no surprise the...
Energy efficiency is in the spotlight more these days when the topic of climate change arises. It’s not obvious how the two are linked. Let’s look at exactly what it means to increase a building’s energy efficiency and how it helps reverse climate change. What Is...
We’ve recently seen an uptick in city and county building inspectors asking for mechanical acceptance forms prior to granting an occupancy permit. This trend demonstrates that perhaps code enforcement is catching up to code. As of the 2013 California energy code, effective July 1, 2014, mechanical...
