Abstract
The Zero Village Bergen consists of a total floor area of ca. 92 000 m2, with more than 700 dwellings divided between terraced houses (68% of total floor area) and apartment blocks (25%) and some area dedicated to non-residential purposes such as offices, shops, and a kindergarten (7%). The project is currently in the planning phase and the strategy for achieving the ZEB-O goal1 is based on three steps: first, minimize energy demand through energy efficiency of the buildings; second, maximize PV generation on the buildings' footprint; and third, consider additional measures onsite and nearby (e.g. local heating system with biomass based cogeneration). At the current stage the project has reached the evaluation of step two, and the results are presented in this report, together with some useful insights for step three.

Zero emission building and conversion factors between electricity consumption and emissions of greenhouse gases in a long term perspective
Authors:
Publication Year:
2014
Abstract
The CO2 emissions from a building’s power system will change over the life time of the building, and this need to be taken into account to verify whether a building is Zero Emission (ZEB) or not.
This paper describes how conversion factors between electricity demand and emissions can be calculated for the European power system in a long term perspective through the application of a large scale electricity market model (EMPS). Examples of two types of factors are given: a conversion factor for average emissions per kWh for the whole European power system as well as a marginal factor for a specific region.
Zero Emission Building Concepts in Office Buildings in Norway

Zero emission buildings (ZEB) are buildings with a minimized energy consumption and renewable energy supply with zero greenhouse gas emissions. There is no common accepted definition of zero emission buildings. This is due to issues in defining the boundary of a balance in terms of building site and time frame of this balance. Further, there is no standard on accounting for emissions (on material, components, system, and building level) nor is there a standard for emissions from other building related environments. In this paper the goals for ZEB are specified and implications for components are discussed.

This paper presents a case study of a single-family house, where the effect of using thermal energy storage integrated in the floor is evaluated regarding GHG-emissions during the life cycle. The house has a lightweight wood frame construction, is well insulated, and fulfils the Norwegian energy regulations from 2010. Different floor configurations have been studied, both regarding energy demand and emissions. Floors with PCM panels have been compared with a reference case without thermal energy storage integrated in the floor, and have also been compared with concrete and wood as replacement for the PCM panels. The effect of changing the thickness of the PCM, concrete and wood has also been investigated (5 mm, 25 mm and 50 mm), as well as the effect of changing the emission factor of the energy supply to the building. The simulations have been carried out with three different climates: Oslo in Norway, Prague in the Czech Republic and Rome in Italy.
