Integrated Energy Design implemented in high-rise block construction in Norway

Atelier Oslo

In Norway, near Lervig Brygge in Stavanger, we participated in developing and designing 4 high-rise blocks between 12 to 18 storeys in a total of 159 homes with 150 parking spaces and matching shopping and communal area.

We participated from initial design sketching to the main project where low energy consumption was of outmost importance.

Of noteworthy integrated energy design solutions:
• Optimization of the building’s passive qualities including accumulation of cold and heat, passive solar heat, natural ventilation and daylight.
• Recycling of ventilation air, exhaustion of kitchen and bathroom, heating of water for domestic use and central heating water.
• Individual measurement of consumer spending for each apartment.
• Securing a healthy indoor climate, the construction will be finished in 2014 and will abide with the standards of energy certificate B according to Norway standaed NS 3031 with a maximum consumption of energy of 115 KWh/m2 per year.

Draw up design in collaboration with Esbensen A/S in which Thorkil Jorgensen Consulting Engineers were assisting advisors for Esbensen

Building 17.000 m2 sustainable nursing homes in Denmark
The nursing home centre consists of 201 homes divided into 11 sections. It was rebuilt into a low energy consumption class 1 according to the Danish standard. This meant an optimization of the passive qualities of the building, superior isolating of the building’s exterior walls and general isolation of the building along with controlled recycling of heat from ventilation. These are some of the noteworthy extra sustainable initiatives: Green roofs, fascines as well as accumulation of rainwater. Furthermore, it was suggested to establish 900 m2 of solar cells. Also a universal upgrade of the homes, equal to contemporary and future conditions, was part of the overall project. In the future, Faelledgaarden will mirror that the domicile is home to a variety of people with different backgrounds, ethnicities, qualifications, religion, story of life and interests. Designing phase from January 2011 to June 2011 including the building permit project and main project. Project follow-up until August 2011. The project was completed in collaboration with Esbensen A/S. Building owner is Copenhagen municipality. Architect: JJW Client: Esbensen, 2011

Building owner counseling concerning energy efficient district cooling for Post Danmark A/S

As building owner advisors, we received an assignment on behalf of Post Danmark A/S to study the profitability of joining Copenhagen Energy district cooling program instead of using Post Danmark’s own compressor cooling machines and seawater as coolant.

Back then, the estimated cooling capacity was about 1.2 MW which was used as comfort and server cooling.

The study contains an evaluation of existing and future cooling loads, evaluation of the lifespan of cooling machines and efficiencies, and COP values. Cooling surfaces real usage in order to utilize remote cooling. Phase out of non eco-friendly coolants, securing the safety of the energy supply to server rooms with and without remote cooling.
Data from previous energy consumption and yearly maintenance costs for existing machines was gathered and registered. Costs for new internal installations for district cooling such as a remote cooling unit, piping and BAS were made using rough pricing calculations.

A complex task with many aspects which we solved in collaboration with Esbensen.

Low energy buildings class 1 Almen+, Rammeaftale 2, senior housing, Copenhagen in Denmark
AlmenBolig+ is a new concept developed by KAB which has been approved by the Ministry of Welfare. The project’s goal is to establish a new generation of cheap common family residences catering to independent self-motivated residents, and a new generation of nursing homes. The rent of the homes must be lower than found in traditional common new buildings. So far the whole test project consists of 2.000 homes which will be constructed over a 4-5 year long period. The group has been given 250 homes, total 20.000 m2, which are made from prefabricated modules into low-priced family and nursing homes. The buildings will be constructed in 2 and 3 storeys on different localities on Amager, Copenhagen Denmark. AlmenBolig+ will be constructed as low energy consuming homes, energy class 1. In Denmark each home has its own heating system and is supplied with a recycling heating system with heat pump. The necessary supplementation of heat will be delivered as district heating.

Low energy consumption class 2 Dahl Advokater in Viborg, new office headquarter
The domicile is 3.700 m2 large divided into 3 storeys with an interesting architecture. The building is categorized as a low energy consumption class 2 building. The energy supply consists of natural gas supplemented by hot air pumps. In the heating season, the building is ventilated through balanced mechanic ventilation via preheated fresh air intake in the fronts and central extraction connected to heat pumps in the technician room. The heat pumps use the extracted air to produce heat which is used to preheat the fresh air intake. The rest of the surplus heat from the heat pumps is used as supplement to the central heating. Outside of the heating season, the building is ventilated through natural/hybrid ventilation utilizing the same fresh air intake while the stack effect in the atrium is discarded via automated mechanic controlled toplighting.

Indoor climate Indoor climate inspection, Njalsgade 13 and 15, Copenhagen in Denmark
Indoor climate inspection and subsequently draw up of a report for a 7.800 m2 large office block on behalf of Vej og Park on Amager. The report contains data concerning the thermal indoor climate, the cause of the poor indoor climate and a solution model with budget. Contract price for improvement, 2,2 million USD. To simulate the thermal indoor climate, we used the software program named BSim which calculates the temperature difference hour per hour in a given zone based on the data gathered from the construction of the building, the internal heat load and typical climate conditions.
