Mr. Yost’s wife first noticed the issue and began … Continue reading How a Building Scientist tackles mold on the exterior of his home
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 aspect of designing any project and carries a great deal of influence on the permitting process. In Europe, there are very real country-wide energy usage agreements that set measurable goals for building performance. Continue reading “Why does actual building performance differ so much from energy modeling?”
Sanjoy Malik, writing for Green Biz, discusses an issue that is something most building owners, developers, operators and other stakeholders aren’t too familiar with. However, for those of us with experience in improving/optimizing existing buildings, the issue can be a real deal breaker. What’s the problem? Since de-regulation of the energy utilities, the data produced … Continue reading Untapping the Big Data of Energy Management through innovative business models
On December 8, 2016, an office building in Boulder housing two local high-tech firms had to be evacuated after the partial collapse of the second floor due to a beam whose structural integrity had been negatively impacted. Nearly 280 people were temporarily relocated until repairs could be made. But before repairs can be made, someone … Continue reading Tenants and Boulder city officials alike anxiously awaiting forensic engineering report 7 weeks after partial collapse
