Oseberg viking ship – ODS

In this video we have animated two different vibration patterns of an historic artefact, the Oseberg Viking ship.
What you see is the deflection pattern of 60+ measurement points on the ship coupled together to show how the ship moves under de facto load conditions. Real deflections is in the micro meter range so here they have been magnified for us to see.
In this case the load is caused by floor vibration due to visitors walking more or less in random around the artefact.

This animation/analysis can be used for improving computer models of the ship’s structural dynamics.



Portalen – Lillestrøm

The location south of the railway station in Lillestrøm takes a quantum jump now when Portalen is ready. The new landmark of 50,000 square meters contains hotels, business areas, an office building and two apartment blocks with 144 apartments.

The builder through Jernbanegata AS is OBOS Forretningsbygg AS. Portalen is OBOS’ largest single project ever, with a project cost of over 1.5 billion NOK. The project owner for the residential area is OBOS New Home, project management for Scandic Lillestrøm has been Chinma Holding, while Øyvind Moen AS and OBOS Prosjekt have assisted the building management in addition to OBOS Forretningsbyggs’ own resources. Veidekke Entreprenørs total contract has a value of NOK 821 million excluding fees, and is also Distrikt Oslo’s first project built after the BREEAM-NOR classification.

In recent years, the ten-acre plot has served as a parking lot, but with different owner constellations, efforts have been made to achieve good finances in various project plans. OBOS Forretningsbygg contacted LPO Arkitekter in the fall of 2012, with a wish to get about 50,000 square meters of land in which 40,000 square meters would be above ground.

– There were clear indications about the disposals. OBOS Forretningsbygg wanted an office building in the south, a hotel closest to the train station and homes and shops located in the center. We had a very good internal process that led to this concept, says Beate Bruun of LPO Arkitekter, who won the architectural competition just before Christmas in 2012.

Kvartal 33

One of Lillestrøm’s latest housing projects has brought a new level of modernism and modern architecture to the house buyers in Skedsmo Municipality.

1,800 square meters of business, the quarter is a great place to live and work.
Builder Veidekke Eiendom and contractor Seby are both pleased with the project, which has also been well received by the users.
– We are very pleased with the terms and qualities we deliver to our customers here. And the way Seby has handled the customers has also been fantastic, says project manager Herman Engesgaar in Veidekke Eiendom and the construction company Kvartal 33 AS.
Project manager Jo Andersen in Seby says that the contractor is also pleased with the development and that the residents also have good reason to be.
– I do not want to say that this is normal housing standard. If you look at the outdoor areas, with granite, a great playground and with the architecture we have here, this is a step up from normal living standards. It’s not often you see so expensive outdoor areas in a housing project, says Andersen.

Harvard HouseZero: Design Intelligence as a Platform for Sustainability

Harvard, Snøhetta and Skanska Technology develops ambitious research project, retrofitting an existing pre-1940s building to achieve unparalleled levels of energy efficiency.

Tuesday, May 23, 2017 — The Harvard Center for Green Buildings (CGBC) at the Harvard University Graduate School of Design, in collaboration with Snøhetta and Skanska Technology, are retrofitting CGBC’s headquarters in a pre-1940s timber-framed building to become one of the world’s most ambitious sustainable buildings. As a first-of-its-kind research project, HouseZero demonstrates how to transform a challenging building stock into a prototype for ultra-efficiency, rapidly reducing the level of reliance on energy-intensive technology while simultaneously creating comfortable indoor environments.

HouseZero attempts to address the global environmental challenge of climate change by focusing on existing buildings, which account for energy inefficiency and carbon emissions on a vast scale worldwide. Through intelligent design that generates inspiring work spaces and a comfortable indoor climate, HouseZero achieves groundbreaking reductions in energy use and carbon footprint.

To realize this ambition, the design of HouseZero is driven by highly ambitious performance targets, including 100% natural ventilation, 100% daylight autonomy, almost zero energy required for heating and cooling, and zero carbon emissions, including embodied energy in materials. Once completed, the building will produce more energy over its lifetime than was used to renovate and operate it. This measure considers the building’s total life-cycle, including the embodied energy for construction materials, building operations and equipment plug-loads over a 60-year lifespan.

“Before now, this level of efficiency could only be achieved in new construction,” said Ali Malkawi, professor of architectural technology at the Harvard Graduate School of Design, founding director of the Harvard Center for Green Buildings and Cities and the creator of the HouseZero project. “We want to demonstrate what’s possible, show how this can be replicated almost anywhere, and solve one of the world’s biggest energy problems — inefficient existing buildings.”

Acoustic quality
Acoustic quality as part of the spatial experience of HouseZero has been a major focus. Solutions that condition spatial acoustics through both absorption and diffraction are implemented in the interior. Treatment of the existing structure, from exposure of the beams to creation of double height spaces, has positive effects on both volume and acoustics. The addition of the facetted stairwell is designed to reduce potential disturbance to the working spaces from human circulation.

Christian Krohgsgate 32

The contracting company Bunde Construction AS has been providing the refurbishment on behalf of the property company Anthon B Nilsen Eiendom AS and OBOS Forretningsbygg, who have equal shareholdings in the property Christian Krohgsgate 32 AS with an area of 11,300 square meters. The apartment building was purchased from Aberdeen in December 2014.

Christian Krohgsgate 32 are listed in 1935 as business premises with six floors, and has primarily served as storage up until around 2000. The building is made of reinforced concrete, and bricked with kammerstein of bims. To avoid internal columns, the skeleton is constructed as frame structures over 10.6 meters span. All floors are decorated for factories and warehouses, and the sixth floor is designed as a large fanlight hall. The old building was built in 2000 by the NCC for the Police Immigration Unit, which was located here for a decade.
– We assisted Westerdals Oslo ACT finding new premises and during the inspection here we found out that the building is well suited to their purpose. It has good heights, is robust and has a good amount of daylight, which is well suited for teaching and classrooms. That it is column-free between the floors, is also beneficial, says director of development Fredrik W. Baumann in Anthon B Nilsen Eiendom AS (ABNE) to Byggeindustrien.

Frogner school and youth center

At Frogner in Sørum municipality the first construction phase of a large-scale educational and multipurpose facility is completed – half a year ahead of schedule.
Students and teachers could make use of the new school buildings already in March 2016, while the official opening took place on this year’s school start on August 18. The first construction phase consists of three school buildings that are connected by a culvert, renovation of the existing primary school and outdoor facilities. The project is carried out in a collaboration contract between Sørum municipal property company KF and Betonmast Romerike, which has been the turnkey. L2 Architects have designed the buildings.
To reduce the scale the project is divided into several smaller volumes. The school buildings and the cultural center are gathered around a central square, which is aimed at Frogner city center.
– We have put particular emphasis on good daylight in all teaching areas and workplaces for the teachers by selecting large windows. Large ceiling height in all classrooms are also selected for optimum conditions in terms of light and air, says civil architect Jon Flatebø in L2.
There is great emphasis on universal design, which is step-free access between all buildings. Outdoors there are universally designed walkways, and it will be built a bridge across the valley between indoor swimming pool and building B. That way, you get direct access from the parking lot and into the school building. Indoors energy have been used and effort to get luminance contrast (grayscale contrast) on transitions in materials and stairs. The culvert that connects the three school buildings makes it possible to get through all the buildings without having to go outside.

Munkerud School

A worn and not very functional school and an increased demand for school places, made it most expedient to build a new elementary school in Nordstrand in Oslo.

The old school from 1959, which was extended several times over the years, was laid across the hilly site which is characterized by steep peaks.
– Increased population growth and a very poor condition was behind the decision to build a new school, where LCC-analysis formed the basis for the decision on demolishing and rebuilding. The new school can accommodate 840 students, approximately 200 more than at the old school, says project manager Nina Rønning in Undervisningsbygg Oslo KF.
