Since you probably don't want to look at the south views anyway, the glazing could be twiinwall polycarbonate which is efficient and looks good and is easy to work with.</div><div class="gmail_extra">Performance and design data and examples on low mass sunspaces here:</div><div class="gmail_extra"><a href="http://www.builditsolar.com/Projects/SpaceHeating/Space_Heating.htm#LowMassSS">http://www.builditsolar.com/Projects/SpaceHeating/Space_Heating.htm#LowMassSS</a></div><div class="gmail_extra">Low mass sunspaces basically give you all the gain of windows or collectors with the added benefits of no worries about overheating, useful extra sq footage, and good looks.</div><div class="gmail_extra">Note Nick Pine's three story sunspace at the link above.</div><div class="gmail_extra"><br></div><div class="gmail_extra">You could use a Trombe wall, but they are not very efficient, and unless you need the stored heat they don't have any advantage over regular collectors or windows.</div><div class="gmail_extra">If you search this page for Trombe, there are several examples and a Thermal Storage Wall Design Manual by Alex Wilson.</div><div class="gmail_extra"><a href="http://www.builditsolar.com/Projects/SpaceHeating/Space_Heating.htm">http://www.builditsolar.com/Projects/SpaceHeating/Space_Heating.htm</a><br></div><div class="gmail_extra"><br></div><div class="gmail_extra">On the north wall, I'd consider including good thermal shades with side "energy tracks" to block the flow of air around the edges -- we use some from Symphony Shades and like them. Power up/down would be nice - especially for ones that are hard to reach.</div><div class="gmail_extra"><br></div><div class="gmail_extra">Gary</div><div class="gmail_extra"><br></div></div>
