Associations between house characteristics and inspector-assessed subjective indoor dampness (yes/no) and measured floor and ceiling joist timber moisture were measured, using the 2005, 2010 and 2015 New Zealand House Condition Surveys, involving 1572 timber-framed houses. We conducted logistic (dampness) and linear regression (moisture) for each survey separately and mutually adjusted for other house characteristics (ventilation, insulation, subfloor defects, building envelope condition (BEC) defects, tenure, number of occupants), climate zone (latitude), rainfall and outdoor temperature.

The identification of indoor air pollutants is useful for exposure analysis and air quality management as we spend 80-90% of our time in built environments. We present the results from a study of indoor aerosol composition across a range of residential housing stock in Wellington, New Zealand.

A low-cost, low power consumption indoor environment monitoring device, called SKOMOBO (SKOol Monitoring Box), was developed. SKOMOBO includes the sensors to monitor temperature/relative humidity, carbon dioxide, particulate matter (PM) and motion (PIR). SKOMOBO was developed using the open source software on Arduino Pro Mini.

The purpose of this study was to determine the environmental impacts associated with a deep energy efficiency refurbishment using life cycle assessment. A prototypical refurbished model of an office building located in Auckland, New Zealand was used as a case study. The refurbishment included major changes to the building envelope with additional insulation, modified wall-window ratio, solar shading as well as technical replacement of the lighting and HVAC system.
