Schematic Design

Ecotect and IES Virtual Environments, among other software tools, allow very quick analysis of alternative building forms and mechanical systems, allowing you to test alternative ideas, and develop a single idea in an iterative design process. (See Resources.)

Further develop energy optimization strategies with the design team. Look at reducing loads while creating a comfortable environment within the shell. Look at reducing east and west exposures, and at providing south windows with exterior shades to make a design feature out of passive techniques. Discuss highly efficient system design at this stage, before your design is finalized—for example: 

• double wall systems 
• ground-source heat pumps 
• underfloor air distribution. 

Option 1: Computer Simulation

Develop multiple iterations of your project design to analyze the energy impact of each change. 

Try negotiating a special contract with a vehicle-sharing company for low-emitting or fuel-efficient vehicles.

The program also must have a minimum two-year contract and designated preferred parking for the shared vehicles. 

All cars included in the vehicle-sharing program must be qualified as low-emitting or fuel-efficient by ACEEE. 

Implement a vehicle-sharing program in which one low-emitting or fuel-efficient vehicle is provided per 3% of

Option 4: Vehicle-Sharing Program

Research tax incentives offered by federal, state, or local governments for purchasing alternative-fuel vehicles. This could help offset some of the initial costs.
