Energry and Resource Conservation

Environmentally Sound Development disturbs existing site as little as possible: adaptive reuse, redevelopment of disturbed sites, use existing infrastructure
Site Analysis and Assessment Climate, Solar Altitude and Solar Access, Wind Patterns, Topography, Soil Characteristics, Groundwater and Run-off, Vegetation, Adjacent Land Use, Circulation, Utilities
Solar Altitude and Solar Access Building orientation, passive solar for heating, lighting, and photovoltaics
Climate Plan for microclimates
Wind Patterns Avoid damming cold-moisture air or blocking cool breeze
Topography Building proportions, wind patterns, drainage strategies, gravity-fed lines
Soil Characteristics Texture and load-bearing capacity, footings, and erosion
Vegetation Plant communities, run-off, and solar access
Main goal of Site Development Minimize energy and resource consumption during construction and occupation
5 Steps to guide initial conceptual design 1. Area takeoffs of impervious surface (>20% requires mitigation) 2. Alternative designs to minimize resource cost 3. Topo/hydro impacts (cut/fill, erosion, siltation, groundwater, pollution) 4. Development and maintenance costs 5. Compatibility Index
Minimize transportation needs Develop near amenities, include amenities, support alternative trans, consolidate trans networks
Utilities Locate development in or adjacent to existing, use gravity, consolidate corridors
Building orientation Solar access and align with landscape contours
Construction methods and materials eliminate unnecessary site disruption, use recycled or regionally available materials, albido affect
Bioclimatic Design relating temperature and humidity conditions to design for human comfort
Plateau Hot/Arid: balance extremes, shelter
High Slope Cold: control wind and promote solar gain
Low Slope Temperate: strategic wind and sun by seasons
Bottom land Hot/Humid: air movement
Hot-Arid Region Moisture conserving plants, prevent heat build-up, deflect hot winds, trap cool air, favor eastern slope base
Temperate Region Promote shade and evaporative cooling in warm season, block wind (NE/NW) and promote heat gain in cool season, favor southeast military crest
Hot-Humid Region Maximize breeze, shade, high ceilings, favor top of eastern slope
Human Comfort Temperature 68-80 degrees Fahrenheit
Human Comfort Humidity 80-20%
Human Comfort Wind Velocity 28 MPH
Cold Regions Control winter winds, promote solar gain and storage, favor south-southwest mid of slope
