Orientation-independent plans Home plans that are adaptable to many lots regard- less of orientation should emphasize shading glass areas and avoid a disproportionate number of unshaded windows on any one side. Example 01-1 is a plan similar to many being built today, but with better shading provided. Front and back porches structurally shade most of the glass. A few unshaded windows remain - one in the front (master bath), two on one side (family room and second bath), one on the other side (bedroom 2) and one on the back (bedroom 1) - but overhangs and other shading devices (Chapter 7) can help protect them. Ventilation of the main living areas, kitchen and master bedroom is possible. Bedrooms 2 and 3 require additional openings for ventilation when the doors are closed.

North-facing single family home plans North-facing sites may be the best orientation for an energy-efficient, comfortable home. Example NF- 1 shows a two-story plan with thick block walls indi- cating space for exterior insulation. Note that the overhanging second floor balcony shades the first- floor south-facing glass. There is no unshaded west glass. The Florida room should remain unconditi- oned and can serve as a screened porch in summer. North-facing glass is shaded from direct sun by the projections. Walls create wingwall effects for ventilation in bedrooms 2 and 3. All rooms have good ventilation potential. 1290 SQ. FT.+ 'Q 240 50. KT. Florida room 680 SQ. FT. Plan NF-1, 1st floor Plan NF-1. 2nd floor House Plan Exam~les Plan NF-2a is a simple, small rectangular plan with a hip roof and two-car garage that will fit on most lots. Shading on the west side is provided by the garage and a screened porch. Tinted glass or an alternate shading method should be used on the three small east windows. Closets in bedrooms 2 and 3 act as wingwalls. Cross-ventilation potential for each room is good. 17x1 4 Q 1275 SO. FT. N Plan NF-2a SCREENED 1) PORCH Plan NF-2b varies slightly from NF-2a. It adds wall area but reduces shading problems for the east windows, while maintaining reasonable cross-ventilation potential. A different interior layout is shown in the south-facing plan SF-2, which would also be effec- tive on north-facing lots. i~~ 1275 SO. FT N Plan NF-2b
