Climate adaptation, mitigation, and protecting strategies are becoming even more important as climate change is intensifying. The impacts of climate change are especially tangible in dense urban areas due to the inherent characteristics of urban structure and materiality. To assess impacts of densification on urban climate and potential adaptation strategies a densely populated Viennese district was modeled as a typical sample area for the city of Vienna. The case study analyzed the large-scale densification potential and its potential effects on microclimate, air flow, comfort, and energy demand by developing 3D models of the area showing the base case and densification scenarios. Three methods were deployed to assess the impact of urban densification: Micro-climate analysis (1) explored urban heat island phenomena, wind pattern analysis (2) investigated ventilation and wind comfort at street level, and energy and indoor climate comfort analysis (3) compared construction types and greening scenarios and analyzed their impact on the energy demand and indoor temperatures. Densification has negative impacts on urban microclimates because of reducing wind speeds and thus weakening ventilation of street canyons, as well as accelerating heat island effects and associated impact on the buildings. However, densification also has daytime cooling effects because of larger shaded areas. On buildings, densification may have negative effects especially in the new upper, sun-exposed floors. Construction material has less impact than glazing area and rooftop greening. Regarding adaptation to climate change, the impacts of street greening, green facades, and green roofs were simulated: The 24-h average mean radiant temperature (MRT) at street level can be reduced by up to 15 K during daytime. At night there is only a slight reduction by a few tenths of 1 K MRT. Green facades have a similar effect on MRT reduction, while green roofs show only a slight reduction by a few tenths of 1 K MRT on street level. The results show that if appropriate measures were applied, negative effects of densification could be reduced, and positive effects could be achieved.

The construction industry is one of the most environmentally detrimental industries in the world, impacting directly the use of raw materials, their determination of use involving the whole lifecycle, as well as all their surrounding environment. However, within the building sector, the transition from a linear to a circular economy is still at an early stage. Business models need to be reconsidered to include new and improved methods and innovative services that could lead to a net reduction in the use of resources and minimizing the waste disposed on landfills. In this context, an important role in buildings’ circularity is “deconstruction”, which is understood as a well-considered selective dismantlement of building components, in prevision of a future reuse, repurposing, or recycling. It represents a sustainable alternative to common demolition, which tends to be an arbitrary and destructive process, and although faster and cheaper, it typically creates a substantial amount of waste. The purpose of this article is to analyze the deconstruction potential of buildings and the strategies to apply in order to keep the impacts on the urban environment low. The article aims to facilitate the implementation of circular economy strategies for buildings by proposing common principles for deconstruction as a sustainable alternative to demolition and defining the key points to be applied during the design and planning process regardless of the type of construction system or material used.

Energy efficiency in buildings undeniably plays a vital role in addressing climate change. At the level of building planning, a thorough analysis with thermal dynamic calculations can be carried out to assess energy demand and resulting CO2 emissions of buildings due to the high level of detail usually provided at this stage. In urban planning design on the other hand, energy and resource-related parameters are usually not quantified, as at this stage of the planning process other urban planning factors predominate the concepts. However, numerous aspects that are determined at the stage of urban planning cannot be changed anymore later on in the process even though, they can have a significant impact on the energy demand. This includes the structuring of the building blocks, density and height of the buildings, orientation and inclination of the surfaces as well as greening of the outer shell and availability of direct solar radiation. This paper describes the analysis of parameters, which have a significant influence on energy and resource consumption of urban developments. This includes new developments as well as the existing building stock in order to provide quantifiable indicators for refurbishment and densification measures. The simulation tool CityCalc, which has been developed in a previous research project provides the environment for the analysis. To validate the approach, the identified parameters are analysed in an exemplary case study for a Viennese urban development area. The results aim at identifying and quantifying the key influencing parameters of urban planning design on the energy and resource efficiency of new and existing urban development areas in order to gain essential insights for the integration of climate-relevant factors for future planning processes.

In 2018, the revised Energy Performance of Buildings Directive (EPBD) included for the first time the application of a smart readiness indicator (SRI). Based on the fact that load shifting in and across buildings plays an increasingly important role to improve efficiency and alleviate the integration of renewable energy systems, the SRI is also aimed at providing an indication of how well buildings can interact with the energy grids. With the clustering of buildings into larger entities, synergies related to the integration of renewable energy and load shifting can be efficiently exploited. However, current proposals for the SRI focus mainly on qualitative appraisals of the smartness of buildings and do not include the wider context of the districts. Quantitative approaches that can be easily applied at an early planning stage are still mostly missing. To optimize infrastructure decisions on a larger scale, a quantifiable perspective beyond the building level is necessary to evaluate and leverage the larger load shifting capacities. This article builds on a previously published methodology for smart buildings with the aim to provide a numerical model-based approach on the assessment of whole districts based on their overall energy storage capacity, load shifting potential and their ability to actively interact with the energy grids. It also delivers the equivalent CO2 savings potential compared to a non-interactive system. The methodology is applied to theoretical use cases for validation. The results highlight that the proposed quantitative model can provide a meaningful and objective assessment of the load shifting potentials of smart districts.

In urban areas, summer temperatures are continuously increasing, and cities are aiming at implementing measures to mitigate the urban heat island (UHI) effect. Reducing sealed surfaces and adding plants have been shown to be beneficial for urban microclimates. Green roofs are thus a viable alternative to standard roofs made out of materials that completely seal the top layer. However, roofs are, at the same time, also ideal for the integration of photovoltaics (PVs), as they are mostly unshaded. With both applications competing for the same surface area, solutions must be found that symbiotically combine the benefits of vegetation and renewable energy. Using an interdisciplinary study, various designs were developed for prototypical applications to integrate PV systems into rooftop gardens, with a specific focus on retrofitting flat roofs. The prototypes were analyzed and tested based on structural design aspects, suitable plant choices, and energy output. The results showed that the concurrent integration of PVs and green roofs into the same surface area can be achieved with lightweight construction, which is particularly suitable for existing buildings. The system can contribute to much-needed urban renewable energy generation, the mitigation of the UHI effect, and the provision of recreational spaces.

Urban strategies and the way cities are planned have changed throughout history, adapting to the needs of the inhabitants, infrastructure requirements, and advances in technology. Uses and customs of people and cities are changing and can evolve much faster than in the past, with the result that urban planning is often too slow to adequately meet the current needs of society. In this context, the development of pop-up environments for temporary developments could be a solution to meet the needs of flexibility, adaptation, and resilience of a city. This allows the urban planner to consider systems from a short-term perspective, fulfilling current needs without compromising the development of potentially different activities in the future. The purpose of this research work is to outline the general requirements of pop-up environments in urban developments that allow for adequate integration into urban planning strategies. Based on an extensive evaluation of the existing literature and a series of case studies, the paper analyzes the key elements that define the framework conditions of urban planning strategies for temporary developments that generate a positive impact on the overall urban system.

Building refurbishment plays a key role in the de-carbonization of the European building stock. Whilst the renewal of the thermal envelope increases energy efficiency during the operational phase, the type of material is highly relevant for the overall environmental impact of the refurbishment. Expanded polystyrene (EPS) is most widely used for external thermal insulation systems but is also a material based on fossil resources. Thus, alternatives made from renewable raw materials must be more widely used in order to reach the climate goals. However, comparable data on long-term material effects over the life cycle are needed for developers and planners to make informed decisions. In a Viennese case study for the largest social housing property manager in Europe, two different façade systems have been analyzed to assess the overall environmental impact of the materials. In a comprehensive life cycle assessment, a Multi-Active Façade system based on recycled paper has been compared with a conventional external thermal insulation composite system (ETICS) using EPS. It shows that whilst the evaluation during the operational phase alone results in a similar ecological footprint of the ETICS, the analysis over the whole life cycle provides a clear positive indication for the novel Multi-Active Façade.

As urban densification is on the rise and the population of cities are increasing, strategies for eco-friendly urban development plans are needed in order to ensure the long-term sustainable growth of our cities. Quality of life and socio-economic considerations are in this context equally important as environmental factors such as energy efficiency, resilience and a future proof mobility concept. Especially large scale urban developments require long-term planning as the actual implementation phase can take decades for completion and advances in technology can significantly change over time. However these developments offer the unique opportunity for research and innovation, as accompanying studies can support the projects throughout the whole life cycle ranging from planning to implementation and monitoring during operation. To discuss the challenges and opportunities of large scale urban development projects, two Austrian case studies, that differ in time, scale and overall context have been selected: The solarCity Linz in the county of Upper Austria and the Aspern Seestadt in the City of Vienna.

With the third revision of the Energy Performance of Buildings Directive (EPBD) issued in July 2018, the assessment of buildings now has to include a Smart Readiness Indicator (SRI) to consider the fact that buildings must play an active role within the context of an intelligent energy system. In order to support the development of the SRI, this article describes a methodology for a simplified quantitative assessment of the load shifting potential of buildings. The aim of the methodology is to provide a numerical, model-based approach, which allows buildings to be categorized based on their energy storage capacity, load shifting potential and their subsequent interaction with the grid. A key aspect is the applicability within the Energy Performance Certificate (EPC) in order to provide an easy to use calculation, which is applied in addition to the already established energy efficiency, building services and renewable energy assessments. The developed methodology is being applied to theoretical use cases to validate the approach. The results show that a simplified model can provide an adequate framework for a quantitative assessment for the Smart Readiness Indicator.

The exodus from rural areas and subsequent migration into cities results in vacated housing and infrastructure substance, leaving behind valuable assets from a resource as well as building-heritage point of view. At the same time thousands of persons entitled to asylum are distributed on a quota-based and highly regulatory approach over the Austrian municipalities. From a spatial planning as well as from an architectural position, this raises several questions, which have been addressed in a research project funded under the Austrian Ministry of Europe, Integration and Foreign Affairs: (1) Can persons entitled to asylum be involved in the upgrading and refurbishment of vacant buildings with the purpose of creating their own living spaces? If so, which conditions are necessary for a successful cooperation? (Strategic point of view). (2) Which requirements must potentially adequate empty buildings fulfil in order to be suitable for this purpose? What are the relevant criteria related to building structure, location and infrastructure in this context? (Object-related point of view). (3) What would be the underlying business model based on a cooperation between local small and medium sized enterprises and persons entitled to asylum? (Economic point of view). The purpose of this paper is to present the different approaches of spatial planning and architecture, resulting in a subsequent common methodological approximation towards the joint topics of rural exodus, conservation of building stock and living space for persons entitled to asylum. Due to the sensitivity of the topic of migration and the complexity of the associated framework conditions, the assessment has been limited to an exemplary case study of a single rural municipality in Austria. The empirical results support the following findings: (1) Persons entitled to asylum are not perceived as a potential target group by the real estate market. (2) The requirements of local companies involved in building refurbishment actions do not match the potential of persons entitled to asylum, both from a quantitative as well as qualitative point of view. (3) The concept of matching rural vacancy and subsequent upgrading as well as refurbishment of buildings and the renewal of village centres in cooperation with persons entitled to asylum is currently not supported by the present legal framework conditions. Developing effective synergies between persons entitled to asylum creating their own living spaces and the declining rural population and subsequent building vacancy in rural Austria necessitates a viable legal, infrastructure related and market driven framework.

The waste heat generated from the use of air conditioning systems in cities significantly contributes to the urban heat island effect (UHI) during the summer months. Thus, one of the key measures to mitigate this effect is to limit the use of active cooling systems. In the city of Vienna, air conditioning units are common in nonresidential buildings, but have so far been much less installed in residential buildings. This is mainly due to the fact that the Viennese summertime climate is still considered to be relatively comfortable and planning guidelines related to energy efficiency are already strict, resulting in high-quality buildings in regard to thermal performance. However, during the last decade, an increase in summertime temperatures and so called “tropical nights” has been recorded in Vienna and subsequently the postconstruction installation of air conditioning systems in residential buildings has significantly increased. In a study undertaken for the City of Vienna, a series of passive design measures have been simulated with current and future climate scenarios in order to determine the most effective combination of architecturally driven actions to avoid the use of air conditioning systems in residential buildings whilst maintaining comfortable indoor temperatures.

In Nigeria, there is an estimated deficit of 17 million housing units. Power supply is insufficient, and the electricity supply for about 60 million Nigerians relies on private generators, causing noise, pollution, and high expenditures for mainly imported fuel. Altogether, current challenges clearly demonstrate the need for effective energy efficiency policies targeting also the building sector. The Nigerian Energy Support Program began in 2013, among others, with the objective being to support the Nigerian Government in developing the Nigerian Building Energy Efficiency Code. This paper presents two preparatory activities carried out in order to come up with suggestions for a legal framework well suited for the situation on the ground: the Case Study Building Analysis carried out in collaboration with a Nigerian developer and the Nigerian Building Energy Efficiency Guideline, elaborated together with stakeholders. The results of preparatory activities pointed out that the code must put emphasis on climate adaptive design and must define requirements and procedures in a clear and simple way to allow for effective enforcement. Only then can energy-efficient mass housing be feasible in Nigeria. The paper concludes with a description of the Nigerian Building Energy Efficiency Code (BEEC), officially approved and launched by the Federal Minister of Power, Works and Housing on 29 August 2017.

INTRODUCTION The University of Applied Sciences in Vienna has offered university degree programs in the field of construction for more than twenty years and has thus gained great expertise in developing its curriculum. Founded in 1996, the department of Building and Design consists of six university degree programs. A major strength of the department is the possibility to adapt to recent challenges in a timely manner. As shown in Figure 1, in the winter term 2008/2009, the master's degree program, Sustainability in the Construction Industry, was held for the first time; it was transformed into the master's degree program, Architecture—Green Building, in 2016. In 2013/14 the bachelor's degree program, Architecture—Green Building, started with the first students graduating in 2016. For ten years the department has focused on sustainability within the building, planning and designing processes.

Educational buildings could play leading roles in increasing high-performance building refurbishments across Europe. The city of Vienna has substantially modernized its schools in the last decade, however mostly single refurbishment measures have been undertaken. This is missing the potential of comprehensive and more energy-efficient actions as well as functional adaptations, which become ever more important as school and learning systems are changing. Institutional framework conditions, budget constraints as well as the lack of a coherent methodology have been identified as the main barriers in this context. The research question addresses how qualitative aspects, such as architecture and function, as well as quantitative aspects, such as energy consumption, could be combined in a methodology that can be easily applied by relevant stakeholders. What would a methodology that actively supports stakeholders in their decision-making process for more comprehensive school refurbishments look like? This paper describes a potential approach and its application in a case study. The proposed methodology supports the development of energy- and functionally optimized refurbishment concepts, with a focus on the synergies between energy-related optimizations and state-of-the-art functional room concepts in order to do justice to the changing learning requirements in schools.

This paper deals with climate change mitigation and addresses waste heat reuse as a measure which is until now considered only to a limited extent. The City of Vienna serves as a case study to explore potentials to improve the urban heat supply using waste heat as an additional energy source. As no observation data about waste heat and detailed heating demand is available, this data is derived from proxy data for estimating waste heat reuse potential and residential heating demand patterns. Heat requirements for manufacturing and service provision is explored and, based on the distribution of the companies within the city, mapped as waste heat sources. Employees per company serves as proxy data to allocate the heat volume. Waste heat share and temperature ranges is reviewed from literature. Heating demand is mapped based on floor space of the buildings by age class and building type. Merging supply and demand maps allows to quantify the residential heating demand coverage through local waste heat in the potential supply areas within different distance ranges and housing density classes. In high density housing areas, only a small share of the demand can be covered by waste heat supply even within 250 m distance from sources due to few companies which could provide waste heat. In medium to low density housing areas in Vienna’s outer districts with more industry, a higher share of residential heating demand near the sources can be covered by waste heat within a 250 m distance. Within a 500 m distance, around half of the residential heating demand can be covered only in low density housing areas near the waste heat sources.
