This paper explores the most influential aspects regarding the environmental and economic performance of zero-energy and zero-emission buildings and proposes a pathway for transition in building solutions. A representative zero-energy office building in Norway is investigated with alternative design solutions to achieve zero-emission status i.e., the extensive use of locally generated energy through photovoltaic (PV) panels and the use of materials with low embodied emissions, such as low-carbon concrete and wood. A life cycle environmental and economic assessment is performed to evaluate specific indicators during the building life cycle: cumulative energy (CED), global warming potential (GWP), and equivalent annual cost (EAC).

Aesthetic Preference as Starting Point for Citizen Dialogues on Urban Design: Stories from Hammarkullen, Gothenburg
This article sets out to describe the role of aesthetics in citizen dialogues during the upgrading of a local swimming pool in Hammarkullen, Gothenburg. The swimming pool became an important project because of its role in a larger neighbourhood renovation project that allowed the municipality to focus on citizen engagement and inclusion.

Hva er egentlig et smart bygg? Nå finnes det faktisk et svar!
Alle virker å være enige om at fremtidens bygg er smarte, men hva er egentlig «smart» og finnes det en definisjon på innhold? Dette var spørsmålet partene i Powerhouse-samarbeidet stilte seg for ca. ett år siden, og som nå har resultert i en veileder for smarte bygg – åpen for bruk i bransjen for aktører som ser nytten av et funksjonsbasert rammeverk.

Impacts of future weather data typology on building energy performance – Investigating long-term patterns of climate change and extreme weather conditions
This work aims at answering two research questions: does a method of generating future weather files for building performance simulation bring advantages that cannot be provided by other methods? And what type of future weather files enable building engineers and designers to more credibly test robustness of their designs against climate change?

Public private collaboration in a zero emission context
This aim of study connected to this report is to answer the following research question: «What are the key drivers of success and failure when it comes to public private collaboration in a zero-emission context?» In this regard, a narrative literature review is conducted to find relevant scientific articles and cases. The cases are studied and results are obtained. Results show various success factors and barriers in public private collaboration in the context of zero emission neighborhood. The results are presented.

Responsive building envelope concepts in zero emission neighborhoods and smart cities – A roadmap to implementation
Responsive building envelopes (RBEs) are expected to play an important role in the design of ZENs and future smart sustainable cities. RBEs are useful to optimize the balance between several energy flows at single- and multi building scale, as well as to actively manage both on-site renewable- and purchased energy in addition to improving user experience and indoor comfort by providing an interactive interface with the outdoors. This article provides a review of the potential and the requirements associated with using RBEs to manage complex interactions between buildings, clusters of buildings and utility grids.

From Zero Emission Buildings (ZEB) to Zero Emission Neighbourhoods (ZEN): A Mapping Review of Algorithm-Based LCA
The building industry is responsible for approximately 40% of energy consumption and 36% of greenhouse gas emissions in the European Union (EU). The most efficient way of reducing a building’s environmental impact is addressing it in the design stage. Here, design freedom is the greatest, but uncertainty is high and there is a nearly limitless number of design options.
