Methodology for holistic retrofitting in commercial buildings

This guideline provides the methodology for holistic retrofitting in commercial buildings for the interested stakeholders, along with different steps need to be followed.

The guideline considers technical, energy, legal and economic aspects forming a holistic retrofitting solution for commercial buildings, with the aiming to reduce primary energy consumption of the target building and increase the share of Renewable Energy Sources. Following the methodology of retrofitting, a consumption down to less than 80kWh/m2 per year is achievable project and even more aggressive reduction could be possible depending on the solutions adapted in target building.

This guideline collects all the good practices from EcoShopping project, including the implementation of a pre-retrofit assessment of the building, identification of the most suitable kit of HVAC and Renewable Energy System, lighting and insulation solutions along with a proper Operation and Maintenance control through an Intelligent Automation Unit. Once the retrofitting solutions are chosen, the steps to be followed in order to correctly finalize the process of deployment on the site are explained. After the implementation of the selected solutions for different retrofitting areas, a validation and verification protocol is outlined to evaluate if the real actuation of the retrofitted building corresponds to the expected performance and verify the achievement of the desired energy efficiency and comfort level.

This document is a handy and practical guideline which allows users to follow different steps of the retrofitting process, furthermore, 18 appendixes are also included offering a wider picture of different retrofitting steps, aiming to enable the end user to have a well-informed decision making with information provided in details.
