Research activities previously performed on shorter simulation timeframe had shown that building-integrated photovoltaic/thermal double-skin façade (BIPV/T-DSF) could maintain a comfort temperature within a building, by adopting a fan-assisted ventilated air cavity in summer, and a non-ventilated air cavity during winter in order to reduce overheating phenomena in the air cavity and consequently in the building.
In this paper, a naturally-ventilated BIPV/T-DSF commercial type of building was studied using TRNSYS simulation for enhancing the indoor thermal performance. The TRNSYS building model was calibrated by using in-situ experimental results taken from the existing published studies. Comprehensive comparisons among the naturally-ventilated BIPV/T-DSF, single-skin BIPV/T façade and non-ventilated BIPV/T-DSF for whole year period were presented thoroughly in terms of annual energy demand as well as comfort operative temperatures for commercial buildings in Sydney. Comparative analysis showed that the naturally-ventilated BIPV/T-DSF could significantly reduce cooling demand throughout the year and maintain a better operative temperature in summer compared to the single-skin BIPV/T facade, whereas the non-ventilated BIPV/T-DSF could always reduce heating demand as well as maintain a better operative temperature in the relative cold periods.
Industry misconceptions around high cost and poor market interest in energy efficient homes continue to obstruct the mass adoption of low carbon housing. Josh’s House demonstrates that low carbon housing is accessible and cost effective. The Star Performers series showcases how...Read more
A rapid review on green-rated office buildings, and their operational energy use, found that the conclusions of six studies ranged from the certified buildings performing worse, similarly or much better than the non-certified buildings in terms of energy usage intensity. Two...Read more
In response to feedback, high-income households can reduce their energy use to a larger degree than low-income households (17% vs 3% reduction). This and other insights were gained by two rapid reviews into research, both Australian and International, on digital services and...Read more
Maintaining indoor thermal comfort is crucial for the health and productivity of building occupants. Building envelope plays a major role in influencing the impact of outdoor climate and controlling the indoor thermal conditions.
Buildings are major consumers of energy for heating and cooling. The number of buildings is growing rapidly with demand for energy. To reduce consumption, governments worldwide have implemented codes, standards, and building practices.
This book focuses on the challenge that Australia faces in transitioning to renewable energy and regenerating its cities via a transformation of its built environment. It identifies innovative and effective pathways for decarbonising the built environment from applied research undertaken by the Co-Operative Research Centre for Low Carbon Living.
This paper explores potential future implications of climate change on building energy expenditures around the globe. Increasing expenditures result from increased electricity use for cooling, and are offset to varying degrees, depending on the region, by decreased energy consumption for heating.
