Full Description

Current building regulations are designed toensure that buildings, including newly built and retrofitted residentialdwellings, are more energy efficient. This has raised concerns and practicalchallenges in relation to maintaining acceptable indoor environmental and airquality. However, there are minimal data available regarding long-term indoorair pollutant concentrations in low-energy residential buildings. The majorityof studies to date have focused on using the traditional research approach thatuses research-grade equipment; however, this approach has limitations in theability to obtain longer-term measurements. The current study usescustomer-grade sensors with the capability of remotely transmitting informationto conduct a longitudinal monitoring campaign. These sensors have beeninstalled in four rooms per dwelling in highly-energy efficient Irishdwellings; two habitable rooms (living room and bedroom) and two wet rooms(kitchen and bathroom). The sensors collect indoor environmental and airquality data; temperature, humidity, CO₂, VOCs, radon and airpressure. The sensors will be collecting data continuously for 18 months, twowinter periods (heating season) and a summer period. While data collection isstill ongoing, a cumulative of 43,120 days worth of data has already beencollected. This paper presents the data from a sample of 20 randomly selecteddwellings. The initial findings highlight a considerable distribution of datawithin dwellings, demonstrating the ability of long-term monitoring campaignsto capture indoor air pollutant fluctuations. Data analysis is still ongoingand is focusing on identifying temporal trends in indoor environmental quality,accounting for factors including occupants activities, buildingcharacteristics, seasonal variations, and the effectiveness of the ventilationsystem (natural vs mechanical ventilation systems).
