Nielsen, B.F, Woods, R. & Lerme, W. (2019):

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.

Predictive rule-based control to activate the energy flexibility of Norwegian residential buildings: Case of an air-source heat pump and direct electric heating

The building energy flexibility potential of a Norwegian single-family detached house is investigated using predictive rule-based control (PRBC) and building performance simulation (using IDA ICE).

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?

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.

Influence of occupant behavior and operation on performance of a residential Zero Emission Building in Norway

Influence of occupant behavior on a residential ZEB was analyzed.
Occupant behavior may change the annual energy balance reliability by 20%.
Occupant behavior may result in grid stress variation from −5% to +13%.
Window openings and DHW would not change significantly the ZEB energy performance.

Using a segmented dynamic dwelling stock model for scenario analysis of future energy demand: The dwelling stock of Norway 2016–2050

A dynamic and segmented dwelling stock model is applied for energy analyses.
A case study was conducted for the Norwegian dwelling stock 2016–2050.
More advanced and/or frequent renovation give limited additional energy savings.
Use of local energy sources, e.g. heat pumps and PV, has a large future potential.
User behaviour is likely to strongly reduce the real energy savings in the system.

The impact of Zero Energy Buildings on the Scandinavian energy system

We analyse cost-optimal integration of ZEBs in the Scandinavian energy system.
We capture impact of short-term uncertainty on long-term investment decisions.
ZEBs reduce the investments in the electricity and heating sector.
The Scandinavian electricity sector is capable of integrating ZEBs with PV.
The operation of the flexible hydropower is changed with ZEBs.

Analysis of the impact resolution has on load matching in the Norwegian context

Generation of energy at building level has an increasing interest in Norway, as in rest of Europe. Load matching is the correlation between the buildings generation and load, which in most cases aims at optimization of the amount of self-consumption. When analysing generation in relation to load, it is of interest to study the choice of resolution and what impact this has on load match indicators. This study analyses the importance of choosing the right resolution, starting with hourly measurements, and going down towards one-minute resolution.

Thermal conductivity of cement stabilized earth blocks

Thermal conductivity of cement stabilized earth blocks (CSEB) increases with bulk density.
Thermal conductivity of CSEB slightly varies with the addition of cement.
Compressive strength of CSEB increases with increasing cement content.
