Abstract There is an increasing interest in development of coupled multi-layer window structures. This is to optimize thermal properties and to develop systems with a better climate protected solar shading system. The risk of condensation on the inside of the exterior glass layer in a multi-layer window structure might be a challenge and is often questioned. The risk of condensation will depend on both window properties and indoor and outdoor climate conditions. The air gap between the inner and outer part have to be ventilated with outdoor air to give the window a "drying out" capacity. The U-value of the…


This report deals with how to define what a Zero Emission Building (ZEB) is with explanation and analysis of different parameters related to embodied emissions of CO2 equivalents. The report can be used as a guidance tool on how to assess embodied emissions, and also on what parameters should be evaluated in such an assessment. Different ambition levels for ZEBs may include life stages, operation, material, construction and end-of-life and can be documented according to EN 15978. Calculation procedures should include system boundaries, embodied emissions from materials, transport, the construction process and waste handling according to the ambition level. CO2 eq…


I ZEB, og som en del av arbeidspakke 5 "Konsepter og strategier for nullutslippsbygg", er det gjennomført en studie av to energikonsepter for boligområdet Ådland i Bergen. Ådland ligger ved Flesland rett sør for Bergen sentrum. ByBo AS ønsker å bygge ut fra 500 – 800 boliger på området hvor både de enkelte boligene og området som helhet skal oppfylle kriterier for nullutslippsbygg. I ZEB er det definert ulike ambisjonsnivå for nullutslippsbygg. Den gjennomførte studien anbefaler et ambisjonsnivå ZEB-O som et gjennomsnitt for Ådland området. ZEB-O betyr at området skal være selvforsynt med energi, inklusive elektrisitet og varme, over et…

Addressing the problem of knowledge integration across the building sectors, a critical stance is taken and tested conceptually, as well as experimentally within an interdisciplinary frame that draws together a number of key literatures from architecture, building science, urban studies, and STS. Empirically, the thesis is supported by a set of interviews and questionnaires that form a grounded case of Switzerland, which evaluates the assumptions and practices around sustainability policies and carbon reduction strategies for buildings and the built environment. As an article based dissertation comprised of four articles that are summarized below, the thesis aims to constructively connect theoretical…

This thesis investigates how the occupant behavior influences the performance of residential net zero emission buildings (Net-ZEB) in cold climates such as in Norway, and proposes guidelines for better design, operation and control strategies. The thesis focuses on the occupant related variations in the internal gains and the domestic hot water use, and studies their influence on the building’s heating needs, its heating system performance and finally, its interaction with the onsite renewable generation and the grid. The application of the tightly insulated envelope in Net-ZEB significantly reduces the space heating needs. This increases the share of the occupant-related heat…
