A static rooftop shading system for year-round thermal comfort and energy savings in hot climates.

In sun-drenched regions, balancing solar exposure for thermal comfort and minimization of cooling energy presents a key challenge. While passive shading mitigates summer heat gain, it also hinders winter solar benefits, a problem that is echoed by active systems such as photovoltaic panels. Existing adaptive solutions, adjusting to seasonal sun angles, offer flexibility, but introduce complexity, maintenance demands, and potentially higher costs.

Local Weather Station Design and Development for Cost-Effective Environmental Monitoring and Real-Time Data Sharing.

Current weather monitoring systems often remain out of reach for small-scale users and local communities due to their high costs and complexity. This paper addresses this significant issue by introducing a cost-effective, easy-to-use local weather station. Utilizing low-cost sensors, this weather station is a pivotal tool in making environmental monitoring more accessible and user-friendly, particularly for those with limited resources.

A Field Study of Nonintrusive Load Monitoring Devices and Implications for Load Disaggregation.

Evaluations of nonintrusive load monitoring (NILM) algorithms and technologies have mostly occurred in constrained, artificial environments. However, few field evaluations of NILM products have taken place in actual buildings under normal operating conditions. This paper describes a field evaluation of a state-of-the-art NILM product, tested in eight homes.

Smart Homes as Enablers for Depression Pre-Diagnosis Using PHQ-9 on HMI through Fuzzy Logic Decision System.

Depression is a common mental illness characterized by sadness, lack of interest, or pleasure. According to the DSM-5, there are nine symptoms, from which an individual must present 4 or 5 in the last two weeks to fulfill the diagnosis criteria of depression. Nevertheless, the common methods that health care professionals use to assess and monitor depression symptoms are face-to-face questionnaires leading to time-consuming or expensive methods.

Facilitating energy savings with programmable thermostats: evaluation and guidelines for the thermostat user interface.

Unlabelled: Thermostats control heating and cooling in homes - representing a major part of domestic energy use - yet, poor ergonomics of these devices has thwarted efforts to reduce energy consumption. Theoretically, programmable thermostats can reduce energy by 5-15%, but in practice little to no savings compared to manual thermostats are found. Several studies have found that programmable thermostats are not installed properly, are generally misunderstood and have poor usability.
