Energy Evaluation with ARCHICAD

SUSTAINABILITY – Industry-first Fully BIM-integrated Energy Evaluation

GRAPHISOFT continues to innovate in “green”, uniquely offering the best workflow for sustainable design, integrated in its BIM authoring tool. The built-in Energy Evaluation functionality of ARCHICAD 16 is based on entirely new technology, which allows architects to perform reliable dynamic energy evaluation of their BIM model within ARCHICAD, relying on BIM geometry analysis and accurate hour-by-hour online weather data of the building’s location.

ARCHICAD's Energy Evaluation functionality offers an easy-to use workflow for performing dynamic building energy calculations on projects of any size.

General Modeling Conventions
General Modeling Conventions

It is recommended to keep in mind a couple of modeling conventions and practices when creating a building model for energy evaluation. In this clip we will present the most important modeling guidelines and conventions.

Working with Zones
Working with Zones

In this movie we will present how to model Zones for energy model analysis in ARCHICAD. A separate Zone has to be created in every conditioned space of the building, using either the Manual or the Inner Edge Zone construction method.

Energy Model Review
Energy Model Review

In this movie we will run the Energy Evaluation and get familiar with Energy Model Review. The automatic model geometry analysis turns the ARCHICAD Building Information Model, so called BIM, automatically into a Building Energy Model, so called BEM.

Structures List Display
Structures List Display

The Structures tab page of the Energy Model Review palette lists the space boundaries on the building's external and internal structures, with all their physical properties that are relevant to the energy simulation.

Opening List Display
Opening List Display

The Openings tab page of the Energy Model Review palette lists the space boundaries on the building's external openings, with all their physical properties that are relevant to the energy simulation.

Building Energy Model Visualization

The Energy Model Review palette enables you to visualize the energy model in different ways.

Customizing Model Review Colors
Customizing Model Review Colors

A separate color is assigned to each space boundary category in Energy Model View. These Energy Model Review Colors can be freely customized.

The U-value Calculator
The U-value Calculator

U-value refers to the heat transmission coefficient of the selected structure. Structure items are listed with default U-values. The U-value Calculator calculates the average heat transmission coefficient value based on a simplified algorithm.

Thermal Property Assignments
Thermal Property Assignments

In this video we will show how we can assign thermal properties to ARCHICAD structures.

Material Catalog
Material Catalog

The Material Catalog is an extensive database integrated within Energy Evaluation that contains building material information relevant to the energy calculations.

Working with Composite Structures and U-values
Working with Composite Structures and U-values

In this movie we will create a new insulation type for the ground floor and then we will modify the U-value of this floor.

U-value Override
U-value Override

The Energy evaluation in default uses the U-value calculator to define the Heat Transmission Coefficient from the various thermal properties, but you can also overwrite the U-value.

Defining Infiltration
Defining Infiltration

Infiltration refers to the air permeability of the selected structure. The unit of infiltration is liter per second, per square meter.

Defining Surface
Defining Surface

In this movie we will show you how to set the Surface settings in the Structure list. The Surface material property determines the solar energy absorption properties of the selected structure.

Setting Up Glazed and Frame Parameters
Setting Up Glazed and Frame Parameters

The Openings tab page of the Model Review dialog box lists data for all of the openings on the building shell. In this movie we will become familiar with how to set up the glazed and opaque parts of the openings.

Setting Up Shading and Shading Devices
Setting Up Shading and Shading Devices

In this movie we will show you how we can set the vertical and horizontal shading and also how we can choose various shading devices for openings.

Environment Settings: Location and Climate
Environment Settings: Location and Climate

In this movie we will set up the location and climate date of the project. ARCHICAD offers an easy location set up and helps to get climate information quickly.

Environment Settings: Grade Level, Soil Type, Surroundings
Environment Settings: Grade Level, Soil Type, Surroundings

In this movie we will discover more settings in the Environment Settings dialog box. The connection of the ground with the building can be modeled in two different ways for Energy Evaluation.

Working with the Operation Profile
Working with the Operation Profile

The Operation Profile is an ARCHICAD attribute, assigned to your building for Energy Evaluation purposes. The Operation Profile associates predefined schedules to each Occupancy type, by Hour, for a whole year.

Working with Building Systems
Working with Building Systems

In this movie we will present how we can set the heating, cooling hot-water generation and ventilation type of the projects for Energy Evaluation.

Defining Energy Source Factors and Energy Cost
Defining Energy Source Factors and Energy Cost

In this movie we will specify the energy-related settings.

Working with Green Energy Building Systems
Working with Green Energy Building Systems

In this clip we will provide the green system data for building systems that recover energy or utilize sustainable resources.

Run Energy Simulation and Review the Report
Run Energy Simulation and Review the Report

Once all necessary input data are obtained by meanings of geometry analysis and user input, we can start the Energy Evaluation calculation.

Saving the Energy Performance Report
