ORNL has developed a new thermal energy storage design utilizing low conductivity organic phase change materials.
Buildings are energy intensive and contribute to carbon dioxide emissions while accounting for one-third of energy consumption worldwide. Heat pump technology can assist in electrification and decarbonization efforts.
Concrete floor slab flatness and levelness are parameters often specified in construction documents that contractors must meet to ensure a high quality of construction. However, the measurement of these parameters is cumbersome and time-consuming.
Making existing buildings more airtight is critical in reducing the nation's energy consumption and carbon output. Most current methods of locating building leakage sites are disruptive to occupants and none of the methods can measure the flow of individual leakage sites.
A novel molecular sorbent system for low energy CO2 regeneration is developed by employing CO2-responsive molecules and salt in aqueous media where a precipitating CO2--salt fractal network is formed, resulting in solid-phase formation and sedimentation.
Household refrigerators typically consume 1.5–2.0kWh of electricity per day, and more than 100 million refrigerators are used in US homes, resulting in significant primary energy consumption and carbon emissions.
Building Science Advisor is a web-based tool that allows users to quickly and reliably evaluate the moisture durability of their building wall designs and select the most energy-efficient and moisture-safe design.
