Energy Star suggest these steps to ntegrate energy efficiency into the design approach

As guidelines for an integrated design approach, I found this set of rules from EnergyStar to incorporate energy performance into the building design:

These guidelines are a strategic management approach, not a technical reference, to incorporate energy performance in the building design process. It is a set of suggested actions for design professionals and building owners to establish and achieve energy goals. These guidelines encourage best practices for energy design as part of the overall design process, and can help translate design intent to top energy performing buildings.

• Start Right – Set energy goal and assemble design team
• Pre-Design – Investigate energy design concepts
• Schematic Design – Simulate and compare energy strategies
• Design Development – Confirm that your design energy meets the target
• Construction & Bid Documents – Include energy goal in specs
• Follow Through – Commission building, rate operational performance, and apply for ENERGY STAR

Kansai Electric Power Building

Project Outline

This building was designed to house the Head Office functions of Kansai Electric Power Company. Built as Phase I of the “Nakanoshima 3-Chome Joint Development Project”. One of the basic concepts for this building is a "model building for environmental symbiosis". In areas around windows, the outer frames (columns, beams) protrude by about 1.8m outwards from the window surface. This not only constitutes a shaded exterior but also provides functions such as a natural light intake from the large window surfaces, shielding of sunlight by the canopy, introduction of natural ventilation via the eaves, and space for installation of solar panels. Besides these, we have also introduced a task-ambient air conditioning system, internal heat storage and other technology for environmental symbiosis. The building also features a “communication well” (a three-floor atrium in the high-floor office zone), the aim of which is to communicate widely.

How do we structure the Energy PROJECT?

As a general guideline, it appears that we first have to define best practices in energy efficient buidling/ town planning.

The next step could be to evaluate existing buildings based on our best practices priniciples. That's after the first presentation.
