TU Delft, 2017
In this project, an energy analysis was conducted on a building in Delft, Netherlands, along with its surroundings, to inform the design of a new building optimized for climate performance using the stepped strategy of reduce, reuse, produce. The primary goal was to develop an energy-neutral design and evaluate the building’s projected energy consumption.
The retrofit interventions include a closed greenhouse, a curtain wall in front of the southeast balconies, two glass solar chimneys flanking the same balconies, a ventilation cavity, urban wind turbines, a heat pump system, and PVT panels on the roof. Energy performance simulations were conducted using Uniec and Ces software.
Heat accumulated in the greenhouse is extracted using Fiwihex devices and stored in a seasonal storage system capable of maintaining hot water at up to 80 °C, complemented by a cold storage of 20 °C of equal capacity. A heat pump with a COP of 4 serves as a backup energy source, ensuring consistent performance under varying conditions.
The project demonstrates how integrated design strategies and innovative technologies can achieve energy neutrality while maximizing the use of renewable resources.
