The Solar Decathlon is a competition for universities from all over the world to design, build and operate small experimental solar powered houses. Its first edition took place in the US in 2002. Since 2010 it is in practice in Europe with four competitions and 65 net zero or net energy plus houses build and tested in 10 disciplines (decathlon). The lecture provides an overview and initial experience and findings from the 22nd edition of the competition in Wuppertal, Germany. It represents a profiling on densification in the existing urban environmental, resource efficiency and carbon neutral energy supply towards climate neutrality.

From large generating facilities to modest neighbourhood substations, public power structures are an exercise in dichotomy. Captivating yet mysterious, designed with both powerful function and beauty in mind. Quietly playing a role in the development of cities and supporting the activities of home worldwide, the magic of heritage power plants, pumping houses and substations is often hidden behind metal gates and pressed brick facades punctuated with oversized steel windows and carved decorative ornamentations.Efforts to achieve global goals of carbon-neutrality paired with advancements in infrastructure, utility distribution and alternative energies now forces the reconsideration of many unique historic resources.Brimming with astounding potential, power generation facilities present unique challenges that can be deterrents to redevelopment. Adaptive reuse celebrates the contributions of those who designed, constructed and operated the architectural and engineering marvels that powered the world while deterring exceptional building materials from languishing in landfills.As an increasing number of sites are decommissioned how can they be positioned to power new experiences for generations to come? What redevelopment tools are available to incentivize the adaptive reuse of industrial heritage, specifically public utility architecture? How do government-led approaches to adaptive reuse differ?

Cultural heritage monuments are, to a large extent, public goods of collective consumption, and their preservation is in the public interest of the society as a whole. The benefits arising from the owner's investment and resulting from the existence and the use of a cultural heritage monument are usually not ``consumed'' solely by the owner, but, to a greater or lesser extent, by the whole society or a particular group. In the case of the renovation and remediation of cultural heritage buildings, the life-cycle costs are determined in the operational phase, before the intended renovation or remediation. They should be used to select an economically sustainable solution, with the maximum potential to preserve the cultural and historical value. The paper presents the application designed for the elaboration of plans for the renovation and remediation of cultural heritage monuments, developed in the form of a web interface. The application processes data at the level of individual structural elements. For faster and more comfortable users' work, a database of type objects is used, which combines primary data from the level of structural elements.

The construction industry is responsible for 40 % of the energy consumption and 36 % of the CO2 emissions, and buildings are responsible for a significant part of energy consumption in Europe.Thus, a growing concern regarding environmental impacts in the construction sector is in place. Reducing these impacts and optimise the design process is a major priority, and technology needs to be integrated along with the design to allow for better buildings performance. Building Information Modelling (BIM) methodology is one of the technologies that is revolutionising how the supply chain delivers the construction projects, allowing for an overview of the whole life cycle, keeping track of the data along the process, and potentiating more advanced simulations and supported decisions.The tool proposed in this paper aims to integrate different types of sustainability analysis, namely Streamlined Life Cycle Assessment (LCA), Carbon Footprint, Life Cycle Cost (LCC) and Level(s) framework with BIM. This involves defining adequate Product Data Templates (PDT) and a database structure for BIM objects, including the necessary parameters to enable designers to do holistic and dynamic assessments from early design stages to a complete LCA. Also, considering the importance of using BIM to visualise different scenarios, a graphical interface will be developed to show the key sustainability indicators and support decision-making for more sustainable buildings. The results achieved show that technology must be taken to meet Climate most ambition targets and reduce the impact of construction.

The lack of standard practices and platforms for assessing refurbishment strategies towards Circular Economy (CE) and their impact in global warming constitutes a challenge for the decarbonization of existing building stock. Incorporating data and feedback from designers and practitioners since early design stages is important to feed a multi-criteria dynamic process with multiple dimensions, which must be assessed under a life cycle perspective. To tackle this issue, this paper introduces a new methodology to support the implementation of tailored refurbishment strategies for increased recovery, reuse and recycling of construction materials. The final objective is to build a methodological framework for sustainable refurbishment design in a BIM environment, which aims to facilitate standardized practices in the construction sector, regarding CE, with a positive impact in the mitigation of global warming and the decarbonization of the building stock. To test the development of this methodology, a case study building in Lisbon, corresponding to a 1919 - 1945 archetype is analysed, making use of its BIM model, where BIM standardization criteria and circularity indicators are discussed, in order to be implemented as a Plugin for Circularity.

The climatic data on which the current generation of the Eurocodes are based are mostly about 20 years old, with some exceptions of recent updates at a national level. The second generation of the Eurocodes for structural design is expected to be nationally implemented within next few years and operational National Annexes should be subsequently developed and the climatic maps revised. Some models for extreme climate actions are still missing within Eurocodes including wind action effects due to non-synoptic storms, which are common in most of the world and are of increasing importance in Europe.The aim of this contribution is to analyse how the impact of anticipated changes in European climate could affect the assessment of design weather parameters, including the partial factor design approach for structures according to Eurocodes, based on current knowledge concerning projectionmodels of future climate in Europe.

The construction sector plays an important role in climate change. Thus, there is a pressing need to construct buildings that reduce heat losses, use natural and local materials, exploit renewable sources and ensure high comfort levels with a minimum environmental impact. Reed, considered carbon-neutral and a carbon dioxide sink material, has been used for centuries for diverse uses. Its properties and high availability made it a popular building material, as seen in Portuguese vernacular architecture. Knowing the properties of the reed is a crucial step to ensure successful heritage conservation, optimising these materials, and developing innovative solutions. This paper studies the potential of using giant reed from different Portuguese regions as a thermal insulation material. Giant reed board prototypes (15 x 15 x 5 cm, about 235 kg/m3) were built. Their thermal performance was tested in a hotbox, according to ASTM C1363‑19. The results show that the giant reed harvested on the northern coast of Portugal has better thermal performance than reeds from other regions. However, regardless of the region of the country where the giant reed was harvested, it has a satisfactory thermal resistance (Re ≥ 0.30 (m2.ºC)/W), allowing its use as a thermal insulation material in the buildings.
建筑行业在气候变化中扮演着重要角色。因此，迫切需要建造减少热损失的建筑，使用天然和当地材料，利用可再生能源，并在对环境影响最小的情况下确保高舒适度。芦苇被认为是碳中性和二氧化碳吸收材料，几个世纪以来一直用于各种用途。它的特性和高可用性使其成为一种流行的建筑材料，正如在葡萄牙本土建筑中看到的那样。了解芦苇的特性是确保遗产保护成功、优化这些材料和开发创新解决方案的关键一步。本文研究了利用葡萄牙不同地区的巨芦苇作为保温材料的潜力。建造了巨大的芦苇板原型(15 x 15 x 5厘米，约235 kg/m3)。根据ASTM C1363‑19，在热箱中测试了它们的热性能。结果表明，产自葡萄牙北部海岸的巨芦苇比产自其他地区的芦苇具有更好的热性能。然而，无论在哪个国家的哪个地区，它都具有令人满意的热阻(Re≥0.30 (m2.ºC)/W)，可以用作建筑物的隔热材料。

The environmental impacts, including those related to greenhouse gas emissions, of the construction and deconstruction of buildings come more and more into focus of governments and professional building owners. In new constructions these so-called embodied impacts are often more important than the environmental impacts during 50 years use phase. How did the environmental impacts caused by construction materials and building technologies and their supply chains change during the past three decades? What might be expected in the future? How did LCA contribute to the past development and how did LCA practice evolve during this period? Finally, are current LCA practices suited to support the transformation of the building stock towards net zero greenhouse gas emissions?In a first part, the past as well as the potential future development of the environmental impacts caused by the manufacture of selected key construction materials and their supply chains will be presented. The main measures which lead to lower impacts in the past and which will be needed to further reduce environmental impacts in the future will be named. Current trends will be assessed against their effectiveness to reach net zero greenhouse gas emissions of buildings and the built environment.In a second part the history and evolution of LCI data collection and data management will be discussed. Several aspects will be covered such as information sources, modelling and methodology, environmental impacts (pollutants and resources) covered in the LCIs, IT resources and solutions, and information policies.

One Planet Sustainable Buildings and Construction Programme (SBC), led by the Ministry of the Environment, Finland and co-led by RMIT University and UN Environment Programme was initiated in 2015. Work on circular built environments commenced in the second iteration of the programme’s work plan. SBC was the first global programme that worked on circularity and responsibly sourced materials in the buildings and construction sector. In 2020, the SBC programme published a range of reports focusing on the state of play for circular built environments across specific regions, tied together with a global report. The present focus of the programme is on Africa, Asia and Latin America, where case studies are collected following a common framework.These case studies together with a global survey provide reliable performance data for responsibly sourced building materials in the Global South. The underpinning premise through this process is to support related SDGs across the social, environmental, and economic considerations and enable countries to achieve their targets under the Paris Agreement. This paper presents key findings from this study, largely derived through case studies in the Global South. The results show that not all stages of the building life cycle are addressed through local examples.

This paper is to provide some insights to professionals on the evolution of smart city, to present its concept and appropriate elements based on the author’s 40+ years of experience in international building development projects.With the oil crisis in the 1970s, the use of alternative energy sources such as solar energy and energy saving measures were explored to combat the threat of fossil fuel supply. The concept of intelligent building to improve the productivity of the occupants and energy saving was then emerged in 1980s, followed by the focusing of the built environment like green building and sustainable construction in the 1990s. Various metrics were developed by different countries for assessing green building provisions e.g. LEED in a more structure manner. Building resilience has recently become popular for abating the increasing natural disasters. The features of intelligent building, green resilient building and smart city will be illustrated by making references to developments which were designed and project managed by the author.On a more macro scale, with the rapid advancement of ICT in recent years, the concept of smart city has been advocated. The various definitions of smart city would first be depicted. Based on these definitions, the attributes of smart building and the respective features were suggested. The appraisal of the designed provisions of a mixed development project in Southeast Asia was then illustrated with suggestions on further elements to enhance its smart city characteristics.
