1.1. Shade in site. Analize climate to determine shading and radiation needs. Climate analysis of weather files indicates required design strategies to achieve thermal comfort in indoor spaces (Fig. 1) but can also help to determine when solar radiation is an asset or liability in outdoor spaces. The sun shading chart in Climate Consultant combines solar geometry with outdoor temperature in one diagram making it more useful.
1.2. Determine the placement of the analysis points using a grid or strategically located points (Fig 3).
1.3. Select the points option in Ecotect’s 3d editor. Place these points in the desired positions.
1.4. Select Sun Path Diagram Tool under “Calculate” in Ecotect and place the cursor in the points. Ecotect draws the perimeter of the building mass in the sun path diagram permitting to determine their shading effect during the whole year.
2. Orientation of buildings.
2.1. Radiation of surfaces is calculated using Ecotect to determine best building orientations. A visual analysis is done but total irradiation per surfaces can also be calculated to determine the most efficient surface .
2.2. Orientation and Energy Use.
HEED is used to determine the optimum orientation as a function of energy use. The same building is rotated in different schemes and yearly energy use in the BEPS window or different schemes in the energy costs screen can be compared. All other variables being equal, the building with the lowest energy consumption should be selected.
