This document will introduce the steps for the retrofitting assessment, definition and deployment:
1. Project Setup and Pre-retrofit Survey
2. Energy Auditing and Performance Assessment
3. Identification of Retrofit Options
4. Site Implementation and Testing
5. Validation and Verification
It aims to give an overall concept to guide the user in the different processes and decisions as the assessment of the retrofitting needs, the evaluation of the different retrofitting actuation possibilities, the economic and energetic analysis of each actuation and the decision making of the suitable retrofitting level according to the economic conditions.
The “Project Setup and Pre-retrofit Survey” includes four key activities: analysis of legal framework, benchmarking, surveys, analysis of investment and benefits.
Especially for the pre-retrofitting surveys, as part of Ecoshopping methodology, play an important role and affect greatly the filtering of the retrofit options identified. It is essential to collect the needs and requirements of both owners and end-users, and to identify current dissatisfaction or desired issues that could be simultaneously improved without additional costs. The surveys mainly include owner requirement and end user assessment. The template “Appendix 7. Owner questionnaire” created in Ecoshopping as part of the Ecoshopping methodology can be used as a mean to gather and define building owner’s requirements toward the retrofitting scope and the future market positioning of the building. On the other hand, energy consumption in a building depends on the indoor environment conditions (temperature, ventilation, lighting, etc.) and building operation, which are also tightly related to the particular indoor comfort of the occupants and the indoor air quality regional/national regulations. Opinion from the end users towards the current indoor comfort level can be assessed by using the “Appendix 8. Comfort Questionnaire”, with which, parameters should be improved in order to achieve a better indoor environment can also be identified.
The identification of all the possible options is needed for the best choice of the suitable retrofit option according to the particular conditions. The process for identifying the different retrofitting options has a special consideration in the cases with a staged approach. The key of the staged upgrade approach is to complete improvements to building systems in the order that reflects the influence of one system on another. A simple workflow is introduced in current topic to analyse the retrofit options. Different technologies were introduced.
A Gantt Chart example is provided, monitoring and awareness issues are also included as part of the implementation.
General steps to perform the post-retrofitting assessment is introduced.
