Blower door tests of a group of identical flats in a new student accommodation in the arctic

A new student accommodation for engineering students “Apisseq” was built in the town of Sisimiut, Greenland in 2010. Its purpose is not only to provide accommodation for students. Thanks to its complex monitoring system it enables researchers to evaluate the building’s energy performance and indoor air quality (IAQ) as well as performance of some single components. In summer 2012 a blower door test was performed on all 37 living units out of which 33 are identical single room flats and 4 are larger double room flats.

Energy and Air Infiltration Monitoring of Manufactured Homes in Cold Dry Climates

Single- and double-section manufactured homes were instrumented in 2001-2003 to measure continuous energy usage and air infiltration with respect to the environmental conditions of a windy cold dry climate. The test site near Arlington, Wyoming, USA is ideal for testing the energy (and structural) performance of manufactured housing due to the naturally occurring high winds (in excess of 35 m/s annually) and temperature extremes (+35 to -35C). Tests included tracer gas monitoring, pressurized leakage tests, and infrared (IR) video scans.

A comparison of residential ventilation codes and standards requirements in cold climate areas of the United States of America, Canada and selected northern european countries

The study reviewed each Code/Standard with respect to requirements relating to acommon set of ventilation factors and criteria. The main factors include the following:1. Protection against Depressurization - given the increase in more tightly built homes,how do the differing C/S protect against combustion gas spillage into the dwelling.2. Ventilation Capacity - what are the requirements for total mechanical air changerates, and high and low airflow capacities?3. Contaminant Removal - what exhaust requirements are there for specific rooms inthe dwelling?4.

Dynamic buffer zone - Controlling moisture and heat flow

The building envelope is primarily an environmental separator, which allows indoor spaces to bemaintained at different conditions from the outside environment. Intentional humidification during the heating season is a common practice in cold climates. Moisture escaping from a humidified building due to air leakage through flaws in the air barrier system can negatively affect the durability of the building envelope.
