Recently, in a chemistry lab at Colorado State University, Eugene Chen and Miao Hong achieved a technological breakthrough that could lead to truly recyclable plastics. In their study published in Nature Chemistry in November 2015, Chen and Hong “describe synthesizing a polyester that, when simply reheated for an hour, converts back to its original molecular state, ready for reuse”.
Considerations when specifying foam insulation
Foam insulation in its various forms – polyeurethane (typically sprayed) or polyisocyanurate and polystyrene (typically rigid) – has proven its ability to improve energy efficiency and occupant comfort. With consistent R-values per inch that exceed traditional insulations like fiberglass and cellulose, and the added benefit of better air barrier functionality, foams have become increasingly popular, especially in “green” buildings.
Many Options for Net Zero Homes
As the cost of photovoltaic (PV) solar panels continues to fall, and the impacts of climate change continue to alarm, we find more homeowners pursuing Zero Net Energy (ZNE) homes, with many options for getting there. The trick is to understand a home’s energy demands upfront, to make sure there is adequate area for the PVs, and to improve energy efficiency, which helps keep the PV system ‘right-sized’.
Maximize Your Energy Potential in Conceptual Design
We can provide your project team with conceptual energy modeling feedback with the ground-breaking Sefaira energy modeling software. Able to plug into Sketch Up and Autodesk Revit the program gives instant feedback on energy use and inefficiency sources. By using a quick Sketch Up model or a detailed Revit model, Sefaira provides tools to find options to meet your project's energy efficiency goals.
