<p>A proper heating, ventilation, and air conditioning (HVAC) demand management system plays a prominent role in managing energy intake and taking a significant step towards sustainable housing with the goal of achieving net-zero emissions. Through experiments and simulations, this study investigated the viability of a recently developed adaptive cloud-based Smart Dual Fuel Switching Systems (SDFSSs) controller for residential hybrid HVAC systems. These systems consider various temporal parameters such as weather condition, building thermal demand, fuel price structure, and equipment capabilities into account to optimize space heating system operation, thereby lowering operating costs and greenhouse gas (GHG) emissions. Results show that by integrating SDFSS with existing ASHP technology, GHG emissions could be reduced by over 80 to 90% by 2030 with carbon pricing of $170/tonne. The results of this study could form a modelling and policy framework for different communities and regions. SDFSS would facilitate progressively and cost-effectively transitioning from existing fossil fuel-dominated heating systems to the low-carbon alternative of electric heat pumps powered by clean electricity. Due to the SDFSS’ responsiveness to the random and intermittent nature of renewable energy supply, hybrid heating systems equipped with SDFSS would facilitate wider penetration of renewable energy. Consequently, net-zero emissions could easily be achieved at a greatly accelerated pace before 2050.</p>

“…This makes bifacial PV modules markedly more sensitive to the albedo magnitude and variations than monofacial modules; hence, reliable information about the surface albedo has become important to determine the most suitable PV technology at any site, to obtain reliable simulations of the envisioned system's energy output, and to assess the economic feasibility of any solar power project. Difficulties exist because the calculation of the reflected irradiance on a tilted surface is generally performed following several simplifying assumptions that do not apply in practice (Gueymard et al 2019;Kamphuis et al 2020).…”

Owing to the persisting hype in pushing toward global carbon neutrality, the study scope of atmospheric science is rapidly expanding. Among numerous trending topics, energy meteorology has been attracting the most attention hitherto. One essential skill of solar energy meteorologists is solar power curve modeling, which seeks to map irradiance and auxiliary weather variables to solar power, by statistical and/or physical means. In this regard, this tutorial review aims to deliver a complete overview of those fundamental scientific and engineering principles pertaining to the solar power curve. Solar power curves can be modeled in two primary ways, one of regression and the other of model chain. Both classes of modeling approaches, alongside their hybridization and probabilistic extensions, which allow accuracy improvement and uncertainty quantification, are scrutinized and contrasted thoroughly in this review.
