Contractor Perceptions of Very Energy Efficient New Multi-Story Residential Buildings
- 2014

In: World Sustainable Building 2014 Barcelona Conference. - : GBCe. - 9788469718155

Conference paper (peer-reviewed)abstract
- To facilitate design of policies and strategies which aim to promote a sustainable development of the built environment, a deeper understanding of factors influencing the decisions taken in construction projects is needed. This study investigates Swedish contractors’ perceptions of the new-build of very energy efficiency multi-storey residential buildings (e.g. passive houses). The results of interviews with twenty selected contracts managers disclose several perceived disadvantages and risks associated with such buildings which influence the interest to invest in high energy efficiency. These include several cost and market-related issues as well as issues relating to the performance of the buildings. Without market intervention it seems unlikely that very energy efficient multi-storey residential buildings will diffuse to any substantial degree within the Swedish construction industry.

Regionalization of buildings-stock description as basis for evaluating energy conservation measures - South East Norway and South West Sweden
- 2014

Conference paper (peer-reviewed)abstract
- This paper presents a description of regional building stocks in the South West of Sweden and the South East of Norway and provides a first validation by means of modelled Final Energy Demand, which is compared with available statistics. The aim of the work is to provide a basis for modelling the assessment of effects and costs of various energy conservation measures applied to the existing building stocks of regions within a country. The aggregated descriptions of the national building stocks of Sweden and Norway through representative buildings are downscaled to the regions. We conclude that the uncertainty in the methodology applied is higher for the regions than for the national level, due primarily to less data available for validation than on the national level. This uncertainty raises concern about how targets on increased energy efficiency and emissions reductions and are going to be monitored, if such targets are to be fulfilled.

Refurbishment certification schemes: aspects of productivity and sustainability
- 2014
-
In: Conference Proceedings for World SB14 Barcelona. - 9788469718155 ; , s. 223-231
-
Conference paper (peer-reviewed)abstract
- Sustainability rating tools can be analysed in a productivity perspective. Government regulations, including taxes and fees that make firms internalize negative environmental externalities, reduce the gap between sustainability and productivity. Productivity measurement methods for new construction are difficult to apply to refurbishment projects, and there is no consensus on measuring the sustainability of refurbishment processes. The purpose here is to investigate how sustainability concepts in building certification schemes for refurbishment are related to productivity, using BREEAM Refurbishment Domestic Buildings and LEED for New Construction and Major Renovations as examples. A set of criteria for analysis is developed here. While this BREEAM scheme has its focus specifically on refurbishment, the LEED version has less that is specific to refurbishment processes. These schemes mainly focus on post-refurbishment assessment. Long-term productivity is related to economic sustainability, and recent refurbishment versions of certification schemes in Germany and Japan recognize more than environmental sustainability.

Rebuilding and a conscious and courageous leadership reduced energy consumption more than 80 percent
- 2014
-
In: Sustainable Buildings. Results. - Madrid : GBCE. - 9788469718155
-
Conference paper (peer-reviewed)abstract
- Akademiska Hus AB has the ambition to halve the energy cost from the year 2000 to 2025. Between 2006 and 2010 the Natural Science Building was renovated completely, and a new presence- and pressure controlled air treatment system was installed. The results show that the investments reduced the heat energy consumption with about 80 percent and the building electricity consumption with about 85 percent. Akademiska Hus AB Region North, had in 2010 built the most energy efficient office building in the region, and still the building is one of the most energy efficient buildings in Umeå. The conclusion of the project is that it is possible with quite easy and also viable investments build more energy efficient than the building Code and the building industry in common requires. A strategic work, ambitious objectives and a conscious and courageous leadership seems to be just as important.

A methodology for spatial modelling of energy and resource use of buildings in urbanized areas
- 2014
-
In: World Sustainable Building Conference WSB14 Barcelona. - 9788469718155
-
Conference paper (other academic/artistic)abstract
- This paper presents and discusses a methodology for modeling energy and resource use ofurban building stocks. The methodology integrates and further develops methodologies for energy,carbon and resource use analysis on building stocks with the aim of applying these to a case study ofthe City of Gothenburg, Sweden. Integrating geographical information systems (GIS) in themethodology for modeling of the building stock, allows assessment of the contribution and effect ofvarious strategies to meet environmental goals for municipalities, portfolio owners, such as housingassociations and institutional investors. The methodology identifies different development strategiesincluding various options for refurbishment, add-on and new construction, which are evaluated withrespect to their potential environmental impacts related to the life-cycle of the building, includingconstruction and end-of-life options.
