Monitoring is important, especially in cold climate!

Greenlandic houses need lots of focus in respect of energy potential and indoor climate. A bachelor thesis on “Design, installation and testing of a monitoring system with a focus on energy efficiency and indoor climate for a new building in Sisimiut, Greenland 2013” by Soren Peter Nielsen describes a new single family house and the design of monitoring system of indoor climate with multiple sensors (CO2, temperature, RH, etc), ventilation system and energy (air flows, oil meter, electricity, etc.).

Abstract of the master thesis.

The contractor has prioritized energy efficiency and indoor air quality for the newly built house. As most houses in Greenland, the house has potential risk for poor thermal comfort, high energy consumption and is exposed to the risk of damage from humidity. Therefore it has been important to set up a monitoring system that is be able to provide information on the building’s characteristics, such as insulation, ventilation, energy consumption and indoor climate including temperature, carbon dioxide concentration and relative humidity.

The main idea behind the monitoring system is to “trim” the house performance as much as possible, while making sure to get the best possible indoor climate. In this particular house a ventilation system is installed, which is one of the fi rst for Greenlandic households. The data collected by the monitoring system will be able to tell how a ventilation system works in such an environment.

This paper will describe the design, implementation and usage of the monitoring system and give an overview of some of the potential risks associated with building in the Arctic. Due to the fact that the building was not fully constructed in the summer of 2013, the monitoring system is not physically installed yet.

The monitoring system has been designed to be affordable and robust enough to operate under Arctic conditions without any breakdown or loss of data. Furthermore, all available data is accessible online for both researchers and for the residents. All data is being stored both on a web server and on a portable ash drive large enough to contain at least one year of measurements. In addition the project will serve as a base for further building research in the Arctic and for investigation of solar heating for private households in the Arctic. The project is funded by the Technical University of Denmark (DTU) and the Commission for Scientific Investigations in Greenland (KVUG).

The house itself consists of three floors: A basement, ground and first floor. The basement is mainly used for storage and will not be included in the monitoring system. The ground floor has an area of 99,2 m2 and the first floor is 54,5 m2. The orientation of the house is South West, which enhances the possibilities to set up a solar heating system in the future. The overall goal for the construction is to build a house that is energy efficient and at the same time, healthy to live in. The monitoring system will monitor these two crucial aspects.
