Green energy extraction for sustainable development: A novel MPPT technique for hybrid PV-TEG system
PublikacjaThe Photovoltaic (PV) module converts only a small portion of irradiance into electrical energy. Most of the solar energy is wasted as heat, resulting in a rise in PV cell temperature and a decrease in solar cell efficiency. One way to harvest this freely available solar thermal energy and improve PV cell efficiency is by integrating PV systems with thermoelectric generators (TEG). This cogeneration approach of the hybrid PV-TEG...

Locality in a sustainable urban housing development
PublikacjaEwolucja koncepcji zrównoważonego rozwoju miasta charakteryzuje się odejściem od uniwersalnego modelu na rzecz wielu modeli rownoważenia ze szczególnym uwzględnieniem ich społecznych aspektów. W modelach tych kluczowego znaczenia nabiera skala lokalna. Idea miasta zwartego oznacza w skali lokalnej dążenie do intensyfikacji zabudowy i wielofunkcyjności środowiska mieszkaniowego oraz do realizacji wspólnotowego modelu życia.
