Abstract Buildings are an important part of society's environmental impacts, both in the construction and use phase. As energy performance buildings improve, materials become more as a cause impact. Less attention has been given to those materials. We explore, alternative for conventional buildings, biobased circular building practices. In addition design, we analyze effect urbanization. assess potential close material cycles together with related impact, between 2018 2050 Netherlands. Our results show limited until 2050, result slow stock turnover growth stock. At present, end‐of‐life recycling rates low, further limiting circularity. Primary demand can be lowered when shifting toward or construction. This shift also reduces carbon emissions. Large‐scale implementation construction, however, drastically increases land area required wood production. Material differs strongly spatially depends on degree Urbanization higher replacement rates, but constructed dwellings generally small compared scenarios rural developments. The approach presented this work used strategies aimed at closing sector lowering buildings' embodied different spatial scales.

Abstract Energy sustainability and interconnectivity are the two main pillars on which cutting‐edge architecture is based require realization of energy intelligent devices that can be fully integrated into buildings, capable meeting stringent regulatory requirements operating in real‐world conditions. Luminescent solar concentrators, particularly those near‐infrared emitting reabsorption‐free quantum dots, considered good candidates for semi‐transparent photovoltaic glazing, but despite important advances optical property engineering strategies, studies finished suitable operation still lacking. In this paper, first example a assembled dot luminescent concentrator‐based glazing demonstrated meets all international standards building elements. It also shown these functioning as efficient Visible Light Communication (VLC) receivers even under full sunlight, thus combining wireless connectivity functions realistic solution smart, sustainable buildings.

As urbanization continues to accelerate globally, energy demand in cities is reaching unprecedented levels, contributing greenhouse gas emissions. In response, the concept of net-zero building (NZEB) becoming a sustainable solution for urban needs. NZEB aims achieve footprint by balancing it consumes with produces, primarily from renewable (RE) sources. This comprehensive literature review-based study explores role RE synergies context NZEBs, including discussions on definition and development RE-synergies achieving trends clusters climate change impacts their performance evaluation, policy regulatory frameworks, challenges possible solutions related NZEBs. It has been identified that while customizing definitions align regional supply important, same highly dependent architectural micro-climate features. The assessment effects practices should involve evaluating equilibrium, occupant comfort, interactions grid. There are still some technical, policy, socio-economic need more attention provide further enhancing development/performance NZEBs goal.

Refurbishing existing buildings to reduce energy use is a priority worldwide greenhouse gas emissions. Millions of around the globe have old roofs that are poorly insulated, but with large roof surface areas could potentially provide significant renewable generation. Often, photovoltaic panels simply added onto regardless thermal integrity. However, due weathering, frequently need repairs over their useful life. We evaluate comprehensive methodology using EnergyPlus and TRNSYS simulation tools how best combine solar electric generation improved insulation achieve cost reductions, improve efficiency utilization at time accessed. Advantages combining efforts into single intervention has not been fully explored in building research. further incorporate important impacts PV stand-off arrays on performance from shading long-wave irradiance skies. These influences comfort implications for insulated structures increasing summer heat waves associated climate-related warming. They also strong interaction installed levels. With an example analysis Milan, Italy, we considered three typical residential types wide-use world (single-family, multi-family, apartment complex) different geometries, levels constructions. evaluated two options: re-roofing (roof repair/replacement) refurbishment (energy improvement). optimized via state-of-the-art simulations considering both documented costs. was quantified detail, exploring array affects performance, influence previously considered. This particularly uninsulated where upper floors can experience excessive summertime heating. Both heating cooling needs determine optimal what savings- related costs- be obtained depending differing parameters. found appropriate cost-effective option net primary buildings. Savings alone varied 3% (apartment 17% (single-family). When adding systems initially uninsulated, savings range 55% 80% Shading reduced loads by complexes provided predicted improvements floor dwellings next exposed roofs.
