Performance Evaluation of a Nearly Zero-Energy Office Building in Temperate Oceanic Climate Based on Field Measurements

Abstract

This field study evaluated the building performance of a nearly zero-energy office building near Brussels, Belgium, located in the temperate climatic zone. The building’s thermal comfort and energy parameters were monitored from May 2018 to April 2019. The time-integrated thermal discomfort, primary energy use, and greenhouse gas emissions from the building were then analyzed using the monitored data. The case study evaluated the HVAC system performance with an air-cooled chiller with water cooling coils and a water boiler with water heating coils. The findings indicated an indoor overheating degree of 0.05 °C and an indoor overcooling degree of 0 °C for the observed period. The building’s primary cooling energy use was found to be 37.54 kWhPE/m2.a and primary heating energy use was found to be 46.08 kWhPE/m2.a for the monitored period. The cooling and heating greenhouse gas emissions were 10.14 kg.CO2e/m2.a and 8.34 kg.CO2e/m2.a, respectively. The observed data also indicated that the HVAC system in the building was operational throughout the monitoring period from May 2018 to April 2019, including a 24/7 schedule. Finally, the paper provided implications for practice and future work based on the study findings.

A systematic review on role of humidity as an indoor thermal comfort parameter in humid climates

“…However, this index is based on operative temperature and ignores relative humidity. Another disadvantage of the existing IOD index is that there are no recommended threshold values for limiting short-term and long-term overheating [91,92]. 5.…”

“…3. Therefore, the paper was a strictly qualitative and review-based study, and new thermal comfort assessments and models must be validated by comprehensive experimental field studies with quantitative measurements [92] and qualitative surveys.…”

Performance dataset on a nearly zero-energy office building in temperate oceanic climate based on field measurements

“…1 (a). The dataset from the monitoring campaign is deposited in an open access repository [2] . This dataset includes three different Excel files in .xlsx format that represents multizonal hourly indoor and outdoor ambient temperature values (°C), monthly cooling and heating energy use (kWh/m 2 ), and monthly cooling and heating energy emissions (kg.CO 2 e/m 2 ).…”

“…The monthly cooling and heating GHG emissions were calculated using the monthly energy used data.
