4. Aristotle said in 350 BC: “…homes should be airy in summer and sunny in winter. A house promising these qualities would be longer than it is deep and the main front would face south”

5. Energy Saving Landscape Goals Building/Home layout relative to sun, wind, and views Buffers: climatic, acoustic and visual Landscaping that includes shading Reduced site paving

6. Integrated Design Taking advantage of climate and other natural system characteristics  Surveying and Planning needs to happen in schematics “Whole System” Thinking  Designing with Natural Systems requires thinking of the site and the building as a whole system Choosing a team  Include professionals in the goal setting and decision making  Owner, including their financial team!  Civil Engineers  Landscape Architects  Architects  Contractors/landscape installers  PME Engineers

7. The Building as a System Energy Use Human Comfort Durability

8. Early Decision Making Common issues to address early and “greenly”  Size and Location of mature landscaping versus energy needs  Orientation can effect the ENERGY STAR and HERS score of buildings/homes  The use of passive solar design means: –generally unobstructed exposure on the south –shade on the East and West –the southern exposure should have low height/low maintenance plantings (maintained to bottom of window sill) –the roof is shaded from a direction other than south  Shade HVAC equipment for better performance in cooling season  Shade hard surfaces areas (especially those with thermal mass) around the building can reduce building air conditioning needs  Don’t shade Renewable Energy System installation areas on a roof with mature landscaping  Size and Location mature landscaping versus durability needs  Buildings need air movement around them, mature, unkempt landscaping can block air movement  Plantings can destroy building and hard surface site elements, over time, if not maintained  Land Clearing  Choose responsible fuels to power heavy equipment

True / Solar South = Geographic South Point where earth’s axis passes through Constant; Does not change Compass / Magnetic South Determined by earth’s molten magnetic core Always changing What is Orientation ?

12. Early Decision Making Size and Location of mature landscaping versus energy needs  The use of passive solar design means: –generally unobstructed exposure on the south –shade on the East and West –the southern exposure should have low height/low maintenance plantings (maintained to bottom of window sill) –the roof is shaded from a direction other than south

13. Early Decision Making Size and Location of mature landscaping versus energy needs  Shade HVAC equipment for better performance in cooling season

14. Early Decision Making Size and Location of mature landscaping versus energy needs  Shade hard surfaces areas (especially those with thermal mass) around the building can reduce building air conditioning needs Selecting and planting trees www.ces.ncsu.edu/depts/hort/consumer/factsheets/trees-new/index.html Selecting and planting trees www.ces.ncsu.edu/depts/hort/consumer/factsheets/trees-new/index.html

15. Early Decision Making Size and Location of mature landscaping versus energy needs  Don’t shade Renewable Energy System installation areas on a roof with mature landscaping

16. Early Decision Making Size and Location mature landscaping versus durability needs  Buildings need air movement around them, mature, unkempt landscaping can block air movement  Plantings can destroy building and hard surface site elements, over time if not maintained
