| Presented by: Joanne Frisch |
| THE SOURCEŠ |
| The sun -a star that is the basis of the solar system, that sustains life on Earth | |
| Distance from Earth: 150 million kilometers | |
| Diameter:1,390,000 kilometers | |
| Mass: 330,000 times that of Earth. | |
| AIM: maximize this resource of energy for: | |
| ELECTRICAL POWER LIGHT HEAT | |
| CONSIDER: existing and proposed buildings |
| Factors that affect quantity, quality and timing of solar energy availableŠ |
| CLIMATE | |
| AIM:-maximize heat gain in winter | |
| -minimize heat gain in summer | |
| -consider snow, ice and rain | |
| "LATITUDE" |
| LATITUDE | |
| IMPORTANT FACTORS: latitude, season, | |
| time of day | |
| Solar altitude angle is measured between | |
| horizon and position of sun above horizon | |
| Sun is at highest point in daily path at noon |
| "ORIENTATION:" |
| ORIENTATION: | |
| RE:-latitude of Montreal (45.5¹ N) | |
| -orientation of site | |
| -buildings¹ relationships with one another | |
| -shaded areas, interior vs. exterior spaces, eg: Lore Krill Co-operative Housing Project | |
| Old vs. new, public vs. private -Vancouver, B.C.; 2002 | |
| -Henriquez Partners Architects | |
| SUN STUDIES December 21, 12:00 A.M. vs. June 21 12:00 A.M. |
| December 21, March21, June 21, September 21- 3:00PM |
| December 21, 8:00 A.M., 12:00 A.M., 3:00 P.M., 6:00 P.M. |

| Passive Vs. Active Solar Gain |
| "RE:" |
| RE: LIGHT | |
| Side light | |
| -comes in mostly from South façade | |
| -utilizes light reflected from the ground, from other buildings and from interior spaces | |
| Shading | |
| -overhangs, balconies | |
| -light shelves, | |
| -insulated shutters and shades |
| "Top light" |
| Top light | |
| -skylights, atria, litria | |
| -minimal glare | |
| -open up space | |
| -enables high development density | |
| while retaining contact with | |
| nature and sunlight | |
| -light reaches multiple levels | |
| "RE:" |
| RE: HEAT | |
| solar radiation enters mostly through | |
| South facing glazing | |
| thermal mass | |
| natural convection |

| "ACTIVE SOLAR GAIN" |
| ACTIVE SOLAR GAIN | |
| collect, store, distribute | |
| -solar hot water heating | |
| -auxiliary heat sources | |
| -equipment to be incorporated into design | |
| Photovoltaic (PV) | |
| -materials generate direct electrical current when exposed to light | |
| -basic collector is a photovoltaic cell | |
| -ideal but battery storage is not yet cost effective | |
| Slide 16 |
| "GUIDELINES:" |
| GUIDELINES: | |
| -Consider existing buildings | |
| -Maximize passive solar gain i.e. top light and side light from the South | |
| -Maximize thermal mass in buildings | |
| -Use solar energy system that has some auxiliary mechanical equipment | |
| -Think of technical requirements and design process as ONE |
