- Abstract
- This project consists of a thorough study of an energy efficient and moisture safe row-house, located in the Nordic climate of Sweden. Climate and site analysis, building scale design decisions and finally the evaluation and optimization of its energy performance were different steps of a holistic process aiming at the architectural quality, energy efficiency, comfort and the well-being of users. The final house design is addressing the spatial requirements of the on-going population increase, that is imminent in the developing countries, but while doing so, it exerts minimum impact on environmental resources and avoids ecological damage.

- This project consists of a thorough study of an energy efficient and moisture safe row-house, located in the Nordic climate of Sweden. Climate and site analysis, building scale design decisions and finally the evaluation and optimization of its energy performance were different steps of a holistic process aiming at the architectural quality, energy efficiency, comfort and the well-being of users. The final house design is addressing the spatial requirements of the on-going population increase, that is imminent in the developing countries, but while doing so, it exerts minimum impact on environmental resources and avoids ecological damage. The passive house standards had to be reached by applying passive heating strategies to reduce the heating demand. Increasing thermal insulation thickness and thermal mass elements in the house had a significant role in reducing heat loss and keeping the house warm in winter nights. Other passive house standards, U-values of envelope elements as well as the window-to-wall area played an important role. The moisture risks had to be avoided and the wooden construction proved to function well under the climatic conditions. An innovative method of timing the shading and nighttime natural ventilation was included as a passive strategy for natural cooling. Time period, position and type of shading was optimized according to hourly data and the correlation of internal and solar gains, and their impact on the operative temperature. To ensure summer wind cooling, the interior spatial distribution and circulation areas were designed to exploit the stack effect and cross ventilation by the opening of specific windows. A water retention technique was achieved by coupling recirculated hot water with electrical water heater. The overall energy intensity would finally be assessed and further minimized by the use of an active photovoltaic system on the roof, to exploit the renewable energy of the sun. (Less)
