Integrating Performance Modeling Into the Design Process

Authors Jeff Cole and Micheal Hatten present how to integrate performance modeling throughout the design process.  Starting with the basic four design strategies (Climate, Use, Building Design, and Systems) they outline how to optimize each of those four strategies throughout all the parts of the design process.  Below is a simplified outline of the presentation. 

4 integrated design strategies to consider throughout all phases of design

    -Climate:  see it as a resource, not a limitation

    -Use:  Small adjustments can create a significant difference

    -Building Design:  Orientation, form, and selection of materials are interrelated with opportunities of natural design strategies.

    -Systems:  Integrating climate into load scheduling will make a large difference in energy consumption.

Pre Design

    -Research climate, wind roses, and sun paths early in the process can inform many design choices that will enhance the sustainable aspect of the building.

    -Identify the components of projected use and programming that will impact the sizing of mechanical equipment and consider how these can be modified.

Conceptual Design

    -Think about the seasonal impact of the climate and way that they can be used as resources instead of limitations.

    -With a greater occupancy analysis and more detailed programming, consider the indoor quality.  For example if a lot of lighting is needed to do a specific task, develop a way to use natural daylighting to minimize the need for electric lighting.

    -Form an overall HVAC strategy; include passive systems that will impact the loads for sizing the mechanical units.

Schematic Design

    -Use research and strategies from conceptual design phase to inform the building design.

    -Create the form to take maximum advantage of daylight, natural ventilation, and view from within the building.

    -Develop different exterior shading options to help optimize building performance.

Design Development

    -Use performance modeling to inform decisions about what type of mechanical equipment and use the information to appropriately size the units.

    -Consider integrating daylighting and electric lighting with the use of sensors.

50 Strategies to Get 50% Energy Reduction

All building design choices are related to each other.  An example of this is daylighting design choices on building orientation, sun shading, window choices, and many more design elements.  Using these connections and relationships with other design elements can significantly reduce the building’s fossil fuel consumption.

These 50 strategies, ranging from ways in which architects design buildings, to information on alternative transportation and its’ impact on the world can be used by anyone.

Each strategy includes an overview, typical applications, emerging trend, links to additional resources, and important relationships to other carbon reduction strategies, with an emphasis on integrated design.

ArchiCAD Launches Energy Modeling Tool

For those of you using Graphisoft's ArchiCAD, there is good news in the way of energy efficient design.  Graphisoft recently launched a new energy modeling tool called EcoDesigner that works directly with ArchiCAD to help quickly analyze building energy performance.  Pitched as a "one-click evaluation for architects," EcoDesigner allows an ArchiCAD user to make quick simple decisions about building usage, material performance, etc. and then quickly see the results of such decisions - including yearly and monthly energy usage, basic carbon footprint data and more.
