Schematic Design

Some easily implemented strategies include: 

• daylighting and controls, especially if you are pursuing IEQc6.1: Controllability of Systems—Lighting;
• installing Energy Star appliances;
• energy recovery ventilation, which is especially useful in moderate to harsher climates; 
• and variable speed controls on pumps and fans.

If you are pursuing an additional point or two by complying with Section 3, select the strategies you anticipate pursuing. 

Option 3: Prescriptive—Advanced Buildings Core Performance Guide

Follow EAp2 steps for compliance and documentation.

Option 2: Prescriptive—ASHRAE Advanced Energy Design Guides 

By this stage, the architect should have seen a visual presentation by the energy modeler on multiple building forms with energy-use comparisons. This will help hone in on the most energy-efficient design that also supports the building program.

Consider other techniques to upgrade the building envelope and insulation, such as: 

• High performance glazing
• Spray-foam insulation
• Additional roof insulation
• Highly-reflective roofing application
• green roofs  
• exterior shading devices.

Daylighting makes for welcoming spaces, and can save energy both through reduced electric lighting and reduced cooling load due to the reduced electric lighting. Consider an atrium and skylights to serve ventilation and light functions. Integrate spatial programming within the atrium to utilize the space. See LEEDuser’s daylighting strategy for more.

Ventilation is one of the largest energy end-uses. Look at alternative means of ventilating your building. Consider naturally ventilated spaces, mixed-mode ventilation for moderate climates, and demand-controlled ventilation for mechanically ventilated spaces.

Google SketchUp is good for shading studies, and plug-ins are available for IES and EnergyPlus to support energy analysis of Google SketchUp models.
