The AEDG prescriptive requirements include: 

a maximum allowable window-to-wall ratio;
continuous insulation on the outside of walls;
roofs and floor-slab minimum thermal performance;
minimum window and door thermal performance;
minimum boiler and chiller efficiencies;
and mandatory use economizers or heat recovery ventilation.

If your project team is not comfortable following these guidelines, consider switching to Option 1, which gives you more flexibility.
