Comparison of the environmental, energy, and thermal comfort performance of air and radiant cooling systems in a zero-en...
In an experimental study set in Singapore's tropical climate, we evaluated the thermal environmental performance, energy consumption, and thermal comfort of air and radiant cooling systems, operating at an operative and air temperature of 26 °C. 78 participants across five groups answered thermal comfort surveys in a crossover study design. Environ...
Quantifying the electric service panel capacities of California's residential buildings
This study seeks to quantify the size distribution of existing installed electrical service panels within California's residential buildings, a potentially significant barrier to future decarbonization efforts. A large sample of historical building permit data was collected for municipalities throughout the state, from which permitted panel upgrade...
A holistic platform for accelerating sorbent-based carbon capture
...
Reducing carbon dioxide (CO2) emissions urgently requires the large-scale deployment of carbon-capture technologies. These technologies must separate CO2 from various sources and deliver it to different sinks1,2. The quest for optimal solutions for specific source-sink pairs is a complex, multi-objective challenge involving multiple stakeholders an...
Anthropogenic heat from buildings in Los Angeles County: A simulation framework and assessment
Anthropogenic heat (AH), i.e., waste heat from buildings to the ambient environment, increases urban air temperature and contributes to the urban heat island effect, which leads to more air-conditioning energy use and higher associated waste heat during summer, forming a positive feedback loop. This study used a bottom-up simulation approach to dev...
Implementation of desk fans in open office: Lessons learned and guidelines from a field study
Desk fans allow individual thermal adjustment in shared spaces which increases occupants' thermal satisfaction. When associated with the increase of room conditioning system setpoint temperature, they can also reduce energy use. In comparison to other Personal Comfort Systems (PCS), low-power desk fans can be very efficient for cooling. Nevertheles...
Energy flexibility quantification of a tropical net-zero office building using physically consistent neural network-base...
Building energy flexibility plays a critical role in demand-side management for reducing utility costs for building owners and sustainable, reliable, and smart grids. Realizing building energy flexibility in tropical regions requires solar photovoltaics and energy storage systems. However, quantifying the energy flexibility of buildings utilizing s...
Weather effects on the lifecycle of U.S. Department of Defense equipment replacement (WELDER)
...
Extreme weather has a direct and significant impact on buildings and infrastructure, resulting in billions of dollars of damage each year. This problem continues to grow as climate patterns change and buildings are exposed to new and different hazards than what they were designed to withstand. In order to better plan for the long-range sustainment,...
Defining weather scenarios for simulation-based assessment of thermal resilience of buildings under current and future c...
In response to increasingly severe weather conditions, optimization of building performance and investment provides an opportunity to consider co-benefits of thermal resilience during energy efficiency retrofits. This work aims to assess thermal resilience of buildings using building performance simulation to evaluate the indoor overheating risk un...
Methodological issues with deforestation baselines compromise the integrity of carbon offsets from REDD+
The number of voluntary interventions seeking to generate carbon offsets by reducing deforestation and forest degradation, generally known as REDD+ projects, has increased significantly over the past decade. Offsets are issued based on project performance in comparison to a baseline scenario representing the expected deforestation in a project area...
