District and Building Characteristics

A set of tools for evaluating retrofitting scenarios, especially the potential energy savings and associated costs, were collected and analysed in order to identify tools that could support decision makers. The tools were analysed and compared based on their scope, type of user interface, target group of users, and building use types that they are applicable to. The tools’ operation method, data input need and  level of detail were also considered. In addition, the form of results, the tools’ advantages and disadvantages were also compared which may assist with the decision making on which tool is most suitable for a given project or a certain type of user. The most significant disadvantages were that some tools were found to be applicable for only residential or commercial buildings, whereas some of these tools can be used to analyse several types of buildings. Some of the tools need advanced expert knowledge, while others are only applicable in the USA due to some pre-defined input data, thus restricting the target group of users. With regards to the results, the tools can be classified into two main types: one type is based on comparing retrofitting scenarios, specified by the user, to a base case building and defining associated costs and savings; while the other type offers pre-defined refurbishment scenarios in the form of listed recommended measures that can be compared.

Evaluating alternative design solutions is made easier by the help of the availability of different online modeling tools. There are different criteria under which these tools can be classified. The table below classifies the modeling programs according to the required details of input data and the knowledge of expertise needed to run the models.

Reset wheel: responsible retrofit guidance wheel This Wheel depicts more than 50 measures that can be used for the retrofitting or the refurbishment of traditional buildings. It encourages exploration of the measures, advantages, concerns about their performance and possible interactions between them. http://www.responsible-retrofit.org/wheel/
MIT design adviser A Tool for early-stage design with few data needs. It is a web-based platform. http://designadvisor.mit.edu/design/
E2Rebuild-European Retrofit Adviser Microsoft Excel sheet based Tool for retrofitting residential building stock. Intervention packages are related to the building envelope. http://www.e2rebuild.eu/en/events/workplan/pd/retrofitadvisor/Sidor/default.aspx
NBI-Deep REtrofitScoping Tool Quick analysis for non-residential buildings for the USA climatic zones. http://nbideepretrofittool.twgi.com/Bundler.aspx
CASAnova This implements the EN 832 standard. It predicts the energy consumption of buildings and allows for a quick analysis of the energy performance of the envelope in relation to building energy consumption. This is not suitable for analyzing comfort levels. http://nesa1.uni-siegen.de/index.htm?/softlab/casanova_e.htm
Simergy This calculates the building energy loads/consumption for all type of buildings.  It is suitable for very detailed level calculations, it has a GUI and some templates to make it easier to input the data.  This tool provides heating, cooling, lighting loads and overall energy consumption. http://simulationresearch.lbl.gov/projects/gui
EnergyPlus This calculates the building energy loads/consumption for all type of buildings. It is suitable for very detailed level calculations. It provides heating, cooling, lighting loads and overall energy consumption. http://apps1.eere.energy.gov/buildings/energyplus/
ESP-r ESP-r is a modelling tool for building, equipped to model heat, air, moisture light and electrical power flows at user specified spatial and temporal resolution. Model was developed by Strathclyde University, Scotland. http://www.esru.strath.ac.uk/Programs/ESP-r.htm
