Renovation strategies for the energy consumption of a 1954 single-family house using IDA-ICE
This study was conducted to fulfill the requirements of the owner of an old single-family house to study sustainability practices for implementing energy renovation strategies. The owner’s objective was to renovate instead of building a new project. The focus was to make the building more energy efficient, creating a sustainable environment less vulnerable to climate changes. In this study an energy model of an existing building was created and validated using a calibration method. The calibration process was necessary to achieve a reliable and valid model that was used to calculate energy consumption. The calibrated energy model was utilized to evaluate the energy consumption of a single-family house build in 1954 and study different alternatives applied in the renovation of the building to reduce energy consumption. The goal was to improve the energy performance of the calibrated model using energy strategy combinations which were based on the following parameters: improved insulation, improved infiltration rates, an air-to-water heat pump retrofit, ground-source heat pumps with solar photovoltaic panels and a mechanical supply and exhaust ventilation with a heat recovery system. The energy consumption of the entire building was calculated using IDA-ICE, an energy simulation program. Additionally, source materials such as Motiva’s energy calculations examples, the regulations of the Ministry of the Environment to determine the building’s energy savings, and documents published by Rakennustieto and the Housing Finance and Development Center of Finland were used. According to the results, using a combination of renovation strategies reduced energy consumption. The base case building energy consumption was 158 kWh/m2 year. After the renovations, the energy consumption was 38 kWh/m2 per year. Improvements in the U-values and the installation of a geothermal heat pump with solar panels was the best option for reducing energy consumption. Using this combination, it could be possible to reduce the final energy use by ...
