Design Matrix; V Absorptive surfaces and smaller open spaces radiate less heat to buildings Open spaces have to be seen in conjunction with built form. Above comments says that we can not, always, express the column space of a initial matrix as span of the pivot columns of the echelon form of this matrix.

In mathematics and computer sciencea canonical, normal, or standard form of a mathematical object is a standard way of presenting that object as a mathematical expression.
The distinction between "canonical" and "normal" forms varies by subfield. In most fields, a canonical form specifies a unique representation for every object, while a normal form simply specifies its form, without the requirement of uniqueness. The canonical form of a positive integer in decimal representation is a finite sequence of digits that does not begin with zero.
More generally, for a class of objects on which an equivalence relation is defined, a canonical form consists in the choice of a specific object in each class. For example, Jordan normal form is a canonical form for matrix similarityand the row echelon form is a canonical form, when one considers as equivalent a matrix and its left product by an invertible matrix.
In computer science, and more specifically in computer algebrawhen representing mathematical objects in a computer, there are usually many different ways to represent the same object. In this context, a canonical form is a representation such that every object has a unique representation. Thus, the equality of two objects can easily be tested by testing the equality of their canonical forms.
However canonical forms frequently depend on arbitrary choices like ordering the variablesand this introduces difficulties for testing the equality of two objects resulting on independent computations.Matrix vector products - Vectors and spaces - Linear Algebra - Khan Academy
Therefore, in computer algebra, normal form is a weaker notion: A normal form is a representation such that zero is uniquely represented. Theoretical Understanding Open spaces in any complex are integral part of built form.
The question is-how should they be positioned and how much should there be? After all, any built mass modifies the microclimate. An open area, especially a large one allows more of the 'natural' climate of the place to prevail. So obviously, large open spaces allow for freer air movement.
The built pattern is also important. It can increase, decrease and modify air speeds. Open spaces gain heat during the day.
6 Open Spaces and Built Form
If the ground is hard and building surfaces are dark in color then much of this radiation is reflected and absorbed by the surrounding buildings. If, however, the ground is soft and green then less heat is reflected. Shading by surrounding buildings and trees can reduce heat gain to some extent.
For summer shading, the building will have to be tall because of the high solar altitude. In winters, on the other hand, since the sun is at a lower altitude even low buildings would shade large areas. Heat loss at night by re-radiation also increases with more open spaces. During the day, buildings receive radiation from the sun and sky.
At night this heat is reradiated to the sky. The greater the exposure of the buildings to the sky, the more the heat loss. So not just the roof, the walls also lose heat. If, however, buildings are tightly packed then all walls face each other and have little exposure to the sky.
Then, heat loss occurs only from the roof.
Building Design In hot-dry climates, compact planning with little or no open spaces would minimize heat gain as well as heat loss. When heat production of the buildings is low, compact planning minimizes heat gain and is desirable. This is how traditional settlements were often planned. However, in modern cities, buildings produce much heat of their own.

In such cases heat loss becomes important. In fact, the phenomenon of heat build up in cities leads to the formation of heat islands. The size and scale of open spaces must, therefore, be optimized. If the open space is too large, then there can be too much heat gain.
