The decarbonization of buildings and communities has become a requirement for sustainability. In this regard, South Korea set target net-zero-energy buildings, wherein all public with floor area exceeding 500 m2 must cover 80% the primary energy consumption using renewable systems by 2030. This study investigated improvement maximization from through sharing between retrofitting an existing community. feasibility achieving positive balance was via simulations. community is comprised two...
This study developed a hybrid louver window system (HLWS) that integrates window, natural light and LED technology to address the high electricity consumption cooling energy due heat generated by use in vertical farming buildings. The HLWS comprises transparent double glazing, diffuser, multiple horizontal slats within air cavity, which effectively transmit indoors distribute it achieve required amount of light. dynamically adjusts intensity based on real-time variations maintain target...
This study analyzed the heating and cooling performance of an office building in Daegu, Korea, equipped with amorphous-Si (a-Si) building-integrated photovoltaic (BIPV) windows. EnergyPlus was used to simulate compare loads models for clear glass double-layer, heat-absorbing low-emissivity (low-e) double-layer In addition, impact changes operation time, temperature settings, air infiltration from entrances, internal load were also as these all have a large on loads. Finally, three types...
With global efforts to strengthen various energy-saving policies for buildings reduce greenhouse gas emissions, in South Korea, new laws and regulations have been force since May 2015 install shading devices public include the solar heat gain coefficient (SHGC) reduction performance of evaluation building performance. By making a ventilated air layer outer glass inner lower temperatures surface, it is possible amount flowing into while maintaining same level light transmission as plain...
This study employs an inverse grey-box (IGB) modeling approach, which combines measured data and the physics of systems to predict performance shallow underground thermal energy storage (UTES) with top side insulation. A simplified IGB model UTES was developed using network analysis. Experimental studies were conducted for vertical horizontal configurations. Detailed models representing field experiments TRNSYS simulation tool calibrated from experimental setup. The 4 Resistance 2...
Due to increased grid problems caused by renewable energy systems being used realize zero buildings and communities, the importance of sharing self-sufficiency also increased. In this study, performance an energy-sharing community was investigated improve its efficiency self-sufficiency. For a case smart village selected via detailed simulation. thermal for cooling, heating, domestic hot water produced ground source heat pumps, which were integrated with storage (TES) solar systems. We...
This study conducted an experimental investigation of improved shallow vertical and horizontal configurations underground thermal energy storage (UTES). Detailed models representing the field experiment were developed in TRNSYS simulation tool calibrated using measured data. Additionally, a simplified inverse model UTES for predicting system performance, which incorporates top side insulations as with actual system, was network analysis. The 4 Resistance 2 Capacitance (4R2C) trained tested...
Due to the wide-spread use of photovoltaic (PV) systems, interest regarding economic benefit and energy-sharing from surplus electricity has been raised. In this study, decentralized thermal electric convergence energy prosumers for an community are proposed. For system, a simultaneous heating cooling heat pump (SHCHP) system integrated with network is proposed, performance operating savings proposed were investigated. A smart village located in Busan Eco Delta Smart City was selected as...
