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.

Understanding the 2030 Challenge and Integrated Design

We've all heard about the 2030 Challenge, but how do we make it happen? 
How can integrated design help? 

Buildings create a substantial demand for energy and materials that produce by-product greenhouse gases.  Immediate action to slow, and then reverse, the rate of greenhouse gas emissions over the next couple of decades is key toward stabilizing the current trends in climate change.  To accomplish this, Architecture 2030 has issued the 2030 Challenge, with the goal of "zero net energy" buildings by the year 2030.  

Introduced by Architecture 2030, an independent non-profit organization established by architect Ed Mazria in response to the global-warming crisis, the 2030 Challenge targets the global building community to adopt the following changes:

  • immediate reduction of 50% in fossil fuel energy use for all buildings
  • an equal amount of existing building area renovated annually to reduce fossil fuel energy consumption by 50%
  • rapidly increasing fossil fuel energy reductions, with a 60% reduction in 2010, adding an additional 10% reduction every 5 years, until carbon neutral buildings are the norm by 2030, so
              70% in 2015
              80% in 2020
              90% in 2025
              carbon neutral in 2030!
  • these reductions are based on a comparison to the 2003 CBECS National Average Source Energy Use and Performance Comparisons by Building Type.  Click here for a copy of the 2030 Challenge Target Table.   

These targets may be achieved through integrated and innovative sustainable design strategies, new technologies, and building materials.  Designers practice with numerable constraints: the client's program, occupant's needs, building codes, zoning requirements, site limitations, climate considerations, building systems, equipment, technologies, and materials.

Those adopting the 2030 Challenge are encouraged to achieve the reductions called for largely through proper design--building shape and orientation, natural heating and cooling, daylighting and ventilation strategies, and by using passive strategies before adding active, such as solar panels.

Fundamental innovations needed to meet the 2030 performance goals will have to come from designers learning to rethink the way they design buildings, and begin to see these constraints as energy saving opportunities. 

The Integrated Design Lab can help with design solutions, consulting, energy modeling and analysis for any designers adopting the 2030 Challenge, and help your projects meet the targets outlined by the initiative. 

There are no penalties if a firm fails to achieve reductions for 100% of their projects, however, Architecture 2030 urges firms to have a clear implementation plan that will assist design team members to reach the outlined goals.  Architecture 2030 has also issued a set of recommended immediate actions for firms interested in the 2030 Challenge:

  • Inform all partners, employees, consultants, and clients that the firm has adopted the 2030 Challenge, explain what this entails and why the firm has committed to its targets.
  • Establish energy efficiency as a central tenet of the firm's design philosophy and require energy wise practices in the firm's day-to-day activities.
  • Require that all employees become educated in the design of energy efficient buildings.
  • Hire consultants and engineers who have adopted the 2030 Challenge (or contact IDL-Bozeman)
  • Engage clients in discussions relating to energy efficiency.
