Light Emitting Diode Coating Can Drive Down White LED Light Prices

Scientists in the US created a new light emitting diode (LED) coating from a relatively inexpensive metal organic framework (MOF) in the form of a film coating. This new alternative may be used as an alternative to existing white LED coatings, which are made of more expensive rare elements.

Residential HVAC Maintenance for Energy Efficiency

Proper maintenance is essential to achieving persistent energy savings with a high-efficiency HVAC system. Commonly, issues such as improper refrigerant charge, coil fouling, and clogged filters decrease a system’s performance from its rated efficiency. However, with proper maintenance, the detrimental effects of these problems can be mitigated.

Green Building Water Efficiency Strategies: An Analysis of LEED NC2.2 Project Data

This study analyzes project compliance paths used by a sample of projects that earned water efficiency (WE) credits under LEED for New Construction v2.2. The sample of 448 projects that earned at least one of WE credits 1, 2, and 3 indicate that credit 3 (Water Use Reduction – 90%) and credit 1 (Water Efficient landscaping – 96%) were earned much more often than credit 2 (Innovative Wastewater Technologies – 13%).

Modeling Microinverters and DC Power Optimizers in PVWatts

Solar photovoltaic (PV) module-level power electronics have become increasingly popular for residential and commercial installations. These systems have several benefits over traditional central inverters, such as: Increased design flexibility, Monitoring of system performance as detailed as real time energy production of each panel, Improvement of energy capture from single panels not producing electricity rather than entire strings…
