“About one-fifth of all the heat that enters the average house comes through windows. …external shading is by far the most efficient method for controlling interior heat build-up. The air-wash between the shading screen and the window is also very effective. The screen should have a light-colored finish… Insulation boards placed next to the window pane at night, will help prevent heat losses through glazed openings. Overhangs and horizontal sunshades placed above south-facing windows serve effectively as heat reducers.”

“Glass… is not required for the collection of solar heat. The National Physical Laboratory of Israel… has perfected a highly polished metal surface coated with a molecular-thin black layer of special paint, which absorbs more than 90 percent sunlight. The polished metal radiates very little of the heat it receives. …A south-facing wall fitted out with these plates would really "drink in" solar heat, windows, or no windows.”

“A face at the window,
A tap on the pane;
Who is it that wants me
To-night in the rain?”

“A wind of only 15 mph may increase the heat loss from a window surface by 47 percent or from a concrete wall by 34 percent. Therefore, heating plans have a critical relationship with windbreaks and with wind baffles.”

“Even through the shut window pane, the world looked cold.”

“Open the window of your mind. Allow the fresh air, new lights and new truths to enter.”

“The cold blast at the casement beats;
The window-panes are white;
The snow whirls through the empty streets;
It is a dreary night!”

“Are we not wasps who spend all day in a fruitless attempt to traverse a window-pane — while the other half of the window is wide open?”

“He had the effect on her of a window being thrown open and fresh air and sunlight being let in”

“He who looks through an open window sees fewer things than he who looks through a closed window.”
