3-year monitoring of ventilation, indoor air and electricity use in a single-family house

Description

Monitoring data from a single-family house (two storeys, 150m² floor area) in central Sweden, 2019-2022. A long term study was conducted with a 4-person family living in a newly-built Nordic home. Ventilation system interventions allow indoor conditions and energy consumption to be compared year-on-year, with alternative ventilation hardware and operational modes. Data also covers period of Covid-19 disruptions. • Hourly electricity metering, supplemented by rooftop photovoltaic solar panel production through two years. • Approx 8-minute interval differential pressure meter readings for whole house ventilation flows, using various ventilation systems and operational modes. • Approx 10-minute interval indoor environmental quality monitoring (temperature °C, CO2 concentration ppm, relative humidity %, particulates µg/m³) in master bedroom and in open plan livingroom/kitchen.

Steps to reproduce

Electricity data obtained via property's smart metering. Airflow data obtained from air handling unit main ductwork, using two differential pressure gauges supplied by Luvian AB. Room air conditions obtained from wall-mounted (1,1m height) Luvian LAQ units with NDIR sensor of Winsen MH-Z19 type. Ventilation systems were 1. multizone exhaust ventilation with demand-control functions (2019 to June 2020); 2. mechanical ventilation with heat recovery by flat-plate exchanger (July 2020 to June 2021); 3. MVHR with rotating wheel mositure recovery heat exchanger (July 2021 on).
