ENKLA - Energi Kartläggnings Modell anpassad för Bostadsproduktion - Ett Metod förslag åt Peab Bygg

The law of Energy audit in large companies came into force in Sweden the year of 2014, as a response to the EU's developed Energy-Efficiency Directive. However, the law is not clear for companies such as the construction companies, because of their dispersed operations of both offices and construction sites. One of these companies, Peab, expressed a help on how to identify energy out on the building construction site, as it was unclear in the law how this task should be accomplished. That is where this thesis comes into the picture. The goal of this thesis is to develop a model that will help Peab to map out their energy usage at the construction site for the erection of houses. The thesis process started with a literature study, to find out more about the law and its background. As there were no clear guidelines on how to proceed in the mentioned problem, the process was made by trying different approaches until a workable method was found. This was done through a number of site visits to the chosen case study, the project Landningsbanan, as well as tutorials and meetings with workers at Peab. When the first draft of a model was produced, further investigations were made of how it could be developed to a useful and beneficial tool for Peab. The resulting model, made in Excel, should be easy to use and not cause any greater workload, this in order to expand the possibilities that it actually will be used. Hence, it got the suitable name ENKLA, (Energy Mapping Analysis), which is the Swedish word for easy. In ENKLA information about the current project is to be filled in, the values of energy used and its cost based on bills, as well as which part of the building process that is current during the given month. The model will then present results in different units in both table and graph form, to be useful for many different roles within the company. Another application of the model is to predict energy consumption by inserting possible values, before a project has started. ENKLA is useful both for energy mapping of various projects and to find possible energy efficiency measures. A further thought with ENKLA is to collect measured values from different projects and thereby to provide a database with expected values from projects of house production for Peab Construction. With the standard values the expected energy consumption can be estimated from the very beginning in a project
