Abstract

This research is about the spatial integration of a self-sufficient renewable energy system in selected urban blocks in the neighbourhood Ramplaankwartier in Haarlem, providing the heat demand of the residential buildings located in these selected urban blocks. Solar energy production and thermal energy storage are the selected energy production and storage methods included in this report. These methods are the result of a literature study and its demarcation results. Based on a spatial analysis resulting in energy potentials, ten configurations are set up for the integration of a renewable energy systems. These configurations are divided over three categories with different principles for an energy transition project: (A) 100% gas replacement using the commonly applied placement of panels on roofs. (B) 100% gas replacement using an analysis of energy potentials (C) Configurations aiming for minor spatial impact on the selected urban blocks taking into account the wishes of inhabitants.These ten configuration were assessed on their quantifiable spatial & energy characteristics using a set of selected/modified spatial & energy indicators. Secondly a perceptual analysis was employed on a pilot group of inhabitants during an information night. During a presentation of the configuration results questionnaires were filled in by inhabitants.The results of the quantifiable and perceptual analysis are compared using the the following criteria: energy potential, spatial impact, inhabitants acceptance, amount of m2 used energy production panels & necessary additional technologies. The configuration (C.4), using PVT + large scale heat pump + pit thermal energy storage, is the optimal solution of the investigated energy solutions.Purely based on the energy characteristics replacing 100% of the gas use, the best option would be (combination of configurations C.3 & C.4) using PVT + large scale heat pump + latent thermal energy storage.If spatial/visual impact in the public space of an energy transition project is not possible or there is an aim for zero spatial/visual impact of stakeholders, then the B.1 or C.2 configuration, using flat-plate collectors + pit thermal energy storage (without covered parking), is the best option.This thesis hopes to contribute to speeding up the process of energy transition projects, replacing the gas produced heat demand with a renewable produced heat demand, for the existing built environments in the Netherlands.
