Nowadays, increasing the penetration of renewable heat technologies is an important approach to minimise global primary energy use and reduce CO2 emissions for a sustainable future. Thermoelectric pumps, which have some unique characteristics in comparison with conventional vapour compression can be integrated solar thermal storage form promising technology. However, currently, reliable numerical model TeHPs suitable building simulation lacking benefits achievable TeHP thanks integration are unclear. To solve these issues, this work, experimental apparatus consisting water-to-air unit tank modelled tested first time, under scenarios without storage, respectively. The results found that developed could well predict output performance unit, deviations within 12%. Additionally, when combined better than terms maximum temperature achieved testing box, response speed coefficient (COP) unit. This work not only paves way following building-integrated simulations units, but also provides guidance design systems include storage.

ABSTRACT Renewable energy sources are extensively studied due to their clean and sustainable nature. Human needs can be classified into four categories: heating, cooling, electricity, transportation. Heating electricity have garnered more research attention because of larger share the variety technologies used. To address supply issues, societies considered solar energy, but its reliance on various factors, especially climate, means it doesn't always meet in some regions. This study proposes integrating thermal photovoltaic (PV/T), ground source heat pump (GSHP) systems, controlled dynamically adjust renewable supplied. The system is tested a residential apartment across different climatic cities Iran assess individual collective climate impacts. Results indicate that ST contributes 100% hot humid climates, 59.2% dry, 30.1% temperate humid, 32% cold climates. Meanwhile, PV 2057, 2986, 3441, 4188 kWh/year for heating demand, respectively. In Chabahar, with alone meets needs.

Solar Photovoltaics (PV) is an important contributor to a sustainable energy transition and consists of increasingly affordable accessible technology. Although solar PV policies in industrialized countries have mainly benefited affluent households, non-homeowner market segments often remain underdeveloped. In this paper, we review barriers enablers for investments investigate sustainability aspects its institutional environment. We use focus group data from Flanders (Belgium) residential markets (including social, rental, collective housing), public sector schools, health social care facilities), commercial markets. They common that they are mostly governed or mediated by organizations, very specific regulatory conditions apply. Our main finding that, even times high prices, the savings potential not sufficient condition organizations engage investments. Major include diseconomies scale, split incentive problems, internal organizational barriers, legal uncertainty. Important sharing frameworks framework contracts purchasing. conclude with recommendations on quality, capacity building, development, mechanism design, justice ensure sustainability.
