The dilemma comes in on which glass to use on the southern exposure. Any thoughts on how we might reconcile these competing needs?
To maximize energy efficiency, a house should have a simple, compact shape, with the long axis running east to west. Place 40 to 50 percent of the total glass area on the south side of the house and minimize window

To maximize energy efficiency, a house should have a simple, compact shape, with the long axis running east to west. Place 40 to 50 percent of the total glass area
Because the sun rises in the east and sets in the west, the side of the building that is utilized for solar gain needs to be facing the south to take maximum advantage of the sun''s potential energy.
Solar panels should face true south, not magnetic south. The difference between these directions, called magnetic declination, can vary by up to 30 degrees depending on your location.
The strategic use of south-facing glass in passive solar buildings is both art and science. By carefully selecting the size, glazing type, and shading system for these windows, passive solar design can
Normally for a high summer sun, low solar irradiance occurs on a vertical surface at mid-day and high solar irradiance occurs on a vertical surface shortly after sunrise for an east facing location and just before sunset
Generally, the south-facing windows should have a high solar heat gain coefficient of 0.55 or greater and a low U-factor of 0.35 or less to maximize heat gain and minimize heat loss.
They need to be brightly reflecting toward the outside, so that solar radiation admitted through the glass is reflected by the shade back out through the window.
Summary: Choosing the optimal orientation for photovoltaic glass is critical for maximizing energy efficiency. This guide explores industry best practices, real-world case studies, and data-driven insights to help
In order to increase this you would need some solar input into the house. If the sun is straight up most of the time, not much of it can be expected to enter through vertical glass. With slanted glass you could expect to
