Google bets on massive heat pump system in pursuit of LEED Platinum at new campus

Adele Peters, writing for Fast Company: At a construction site on Google’s new Bay View campus–a few miles from its headquarters in Mountain View, on NASA-owned land near the San Francisco Bay–cranes lift tubing high in the air and drop it into holes that descend 80 feet into the ground. It’s a step that will … Continue reading Google bets on massive heat pump system in pursuit of LEED Platinum at new campus

Net-Positive Earth Moving Equipment?

Massive earth moving equipment ranks among some of the heaviest and most costly machinery in the world, outside of experimental particle physics, of course... Not surprisingly, the mostly diesel-powered mammoth vehicles typically employed for major infrastructure projects require a great deal of that diesel fuel to get the job done. Considering that in many such … Continue reading Net-Positive Earth Moving Equipment?

California: It ain’t easy being a green builder (but there are some real opportunities)

San Diego's Building Industry Association played host to an outstanding and dynamic presentation earlier this morning on the topic of energy and the 2016 California building codes that went into effect at the beginning of this year. The panelists included a great mix of building professionals and thought leaders that don't merely speculate on the … Continue reading California: It ain’t easy being a green builder (but there are some real opportunities)

Without constant monitoring, solar PV efficiency remains limited

Solar panels leveraging photovoltaic (PV) technology to convert sunlight into electricity are notoriously inefficient. According to research by the International Energy Agency, one way to improve PV efficiency is through the implementation of Statistical Performance Monitoring combined with some advanced machine-learning. In their report, the researchers identified 4 different methodologies for improving solar panel efficiency, … Continue reading Without constant monitoring, solar PV efficiency remains limited

Why does actual building performance differ so much from energy modeling?

Energy modeling is not exactly a brand new science, but it certainly hasn't been around very long, either. In essence, energy modeling is a software-based approach to predicting how much energy a given building will use based on its location, orientation, wall/roof/slab design, windows, doors, etc. In California, for example, energy modeling is a critical … Continue reading Why does actual building performance differ so much from energy modeling?
