Recommendations:
- Natural ventilation
- Light coloured building materials and cool roofs (with high emissivity) - minimises conducted heat gain
- Window overhangs (designed for this latitude) or operable sunshades (extend in summer, retract in winter)
- Organize floorplan so winter sun penetrates into daytime use spaces with specific functions that coincide with solar orientation.
- Use high mass interior materials like slab floors, high mass walls, and a stone fireplace to store winter passive heat and summer night 'coolth' .
- High mass interior surfaces like stone, brick, tile, or slate, feel naturally cool on hot days and can reduce day-to-night temperature swings.
- Trees (neither conifer nor deciduous) should not be planted in front of passive solar windows, but rather beyond 45 degrees from each corner.
- High performance glazing on all orientations should prove cost effective (Low-E, insulated frames) in hot clear summers or dark overcast winters.
- Traditional homes in hot dry climates used hign mass construction with small well shaded openings operable for night ventilation to cool the mass.
- The best high mass walls use exterior insulation (like EIFS foam) and expose the mass on the interior or add plaster or direct contact drywall.
