Commercial closed-cell insulation foam boards reduce their thermal resistivity by up to 30% due to gas diffusion in and out of foam cells.
Wind or hydro power are predominantly large-scale with giant generators to convert wind or water captured by turbines into electricity. But residential-sized wind turbines could generate power for a whole house.
There is a strong drive to improve the electrical performance of a power module for power electronics applications including transportation, buildings, renewables, and power delivery.
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.
Wireless charging systems need to operate at high frequency, at or near resonance, to maximize power transfer distance and efficiency. High voltages appear across the inductors and capacitors. The use of discrete components reduces efficiency, increases system complexity.
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.
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.
Technologies for optimizing prefab retrofit panel installation using a real-time evaluator is described.
This solid-state thermal switch can significantly increase the functions of the thermal mass in buildings by actively controlling the thermal resistivity of insulation layers to optimize the energy storage and utilization to shed, shift, and shape HVAC loads on demand.
