Integration of Energy with Ecology and Environment:

Architects and developers have little direct say upon social provision but they need to be
aware of divisions that they perpetrate or help break down, where they can however, have
influence is in another triangular set of relationships. The various international agreements
on the environment and climate change mean that building design has three distinct
perspectives to consider – energy, ecology, and environment.
The concentration upon low energy design is no longer sufficient if true sustainability is to be
met, but conversely, sustainable development that does not have at its centre an energy
strategy is also invalid.
Designers now need to incorporate into master
plans the regenerative potential of ecosystems and to
consider in a holistic fashion the environmental
resource implications of their development
decisions.
It's a tall order, especially with inadequate
information on lifecycle impacts and a construction
industry that appears reluctant to innovate in the
housing sector.
But it's possible to extract indicators from complex
picture and use these to highlight good practice at a
local level.
For example, with energy, one could relatively
easily model different designs against CO2
emissions and other pollutants per year, with
environmental resources, one could measure water
use, and with ecosystems, one could use a single
species (such as the blackbird or toad) as an
indicator of local biodiversity. By using indicators to
model or monitor performance. The full complexity
of sustainable development could be reduced to
measurable parts. It will not tell you the whole
picture, but as a design or management tool it
could point in the right direction

Sustainability

Sustainable development... Is the development that meets the needs of the present without  
compromising the ability of future generations to meet their own needs? There is no future for  
sustainable housing without a culture change in society. Resources conservation can’t be  
achieved without a fundamental review of the type, form and location of housing.  
Housing is not sustainable if it’s cold, damp unhealthy, expensive, and if the community is  
unsafely and unhealthy. The priorities are:  
• Staying warm, living in a safe neighborhood and keeping water bills down.  
• The conservation of natural resources (land, energy, water)  
• The sensible reuse of man made resources  
• Maintenance of ecosystems and their regenerative potential.  
• Equity between generations, people and classes.  
Provision of health, safety and security.  
Sustainable housing will probably display a list of features:  
• Healthy, comfortable, secure homes.  
• Designed in ability to upgrade.  
• Low energy design exploiting renewable energy sources.  
• Super insulated homes.  
• Low water consumption.  
• Public transport oriented urban design.  
• Pedestrian friendly streets  
2.1 key factors considered for sustainable  
buildings  
Sustainable houses offer enhanced comfort, lower energy or water bills, greater self reliance,  
improved health and more relationship with nature.  
Three factors in particular are emerging as essential construction requirements of the sustainable  
house:  
9 Thickness of perimeter fabric.  
9 Air tightness linked to high levels of insulation  
9 Efficient boiler systems.  
Housing form and layout should be generated by the need to achieve simple social pleasures:  
such as having access and views to attractive gardens, each home should have good orientation  
for solar gain so that living spaces have a pleasant and warm ambience for the family, in urban  
areas each home should be connected to a good transportation system, and should be a linkage  
to a clear framework of supporting communy facilities.  
As for the houses the DETR (the Department of the Environment, Transport and the Regions), In  
England they suggest that these are likely to be super- insulated, of high thermal mass, air tight in  
construction and made from building materials based upon no toxic, low embodied energy  
principles.  
In addition, the sustainable house will feature water collection from the rain, sewage treatment,  
waste recycling and local energy generation.

Old Architectural Sketch 2

Bramante, Donato (14441514)
Untitled, Uffizi, UFF 1714 A, Approx. 15.5 _ 16.6cm, Ink on paper
Bramante was one of the first of the great High Renaissance architects, influencing numerous
prominent architects of Rome such as Peruzzi and Sangallo. He is best known for reviving the architecture
of classical antiquity, which had begun with the works of Alberti (Allsopp, 1959). Vasari
reported that Bramante spent much of his time studying and sketching the buildings in Rome
(Vasari, 1907).
Born Donato di Angelo di Anthonio da Urbino/Pascuccio, it is speculated that he studied with
Piero della Francesca and/or Andrea Mantegna. His first notable building was S. Maria Presso S.
Satiro in Milan. In Rome, some of Bramantes most celebrated and influential projects were for
Pope Julius at the Vatican, where he designed the Cortile di S. Damaso and the Cortile del
Belvedere. With an interest in centrally planned churches similar to Leonardo, he also designed a
Greek cross plan for St. Peters with a vast central dome. His expressive building of the classical tradition
was the Tempietto of S. Pietro in Montorio, 1502.
Bramantes design for the Tempietto was sited in the courtyard of the Church and Monastery of
San Pietro in Montorio. It constitutes a diminutive temple acting as a Martyria, standing on the place
presumed to be St. Peters Martyrdom. Small and circular, it revisits antique forms appealing to contemporary
Christians preferences, crowned with a hemispherical dome resembling the Pantheon.
This small monument displays simple proportions where the width of the dome is equal to the height
of the interior cylinder (Allsopp, 1959).
This sketch on the facing page (Figure 1.1) exhibits a small shrine-like structure, representing an
example of a centrally planned building. The sketch reads as an elevation of an octagon-shaped
dome on a raised foundation. In plan, the building presented appears to be shaped in the form of a
cross with small projections containing porches; it is vaguely reminiscent of Palladios Villa Rotunda.
Bramantes concern with the reference to a shrine led him to draw this sketch demonstrating its volume
from the exterior, rather than interior space. Here, he used the porch to accent the central
domed space, stressing the qualities of a monument, a temple from antiquity.
The buildings organization describes an octagon within a Greek cross imposed within a square,
but the sketch presents an image somewhere between a perspective and an elevation, as the face of
the porch has been drawn slightly taller than the side porches. To stress the central altar and promote
a three-dimensional effect, Bramante employs shading on the side of the octagon, further confusing
the flat façade of the elevation. The sculptural figures on the roof have been drawn with the same lack
of complexity as the scale figures standing on the stairs. Although the sketch does not appear to be
hurried, Bramante describes the stairs with minimal detail. The set on the left display some definition,
while the other set of stairs have been represented simply by double diagonal lines. This technique
concentrates the focus to the center, and emphasizes the fact that the building was designed to
be viewed equally well from all angles.
The sketch suggests a self-reflexivity, as it refers to the many centrally planned structures designed
by Bramante. It also recalls the three-dimensional/volumetric qualities of Bramantes concern for a
buildings mass. The architectural historian James Ackerman wrote about the volume of Bramantes
walls: [W]e sense that where the earlier architect drew buildings, Bramante modelled them (1961,
p. 27). Although this design for a small building may not be directly related to the Tempietto, it is representative
of a theme, one that Bramante explored throughout his career.

Peruzzi, Baldassare (14811536)
Study of a sepulchre, Uffizi, UFF 159 A, 12 _ 13cm, Brown ink and wash
A prominent architect of the high Renaissance in Rome, Baldassare Peruzzis approach was influenced
by the work of Bramante and Raphael. His peers respected him for his revival of the art of stage
design, and for his expertise in the art of perspective drawing. Peruzzi arrived in Rome in 1503 from
Siena. He began as a painter under Pinturicchio, and was commissioned in 1509 by the Sienese
banker Agostino Chigi to design the Palace Farnesina. The palazzo reflects his strong sense of proportion
and his interest in the principles of mathematics as set down by Alberti. Different in plan than
other Roman palaces of the time, Villa Farnesina has two wings flanking a central loggia, containing
frescos by Raphael.
Much of Peruzzis experience was obtained in the Vatican Workshop assisting Donato Bramante,
and, later, collaborating with Raphael until 1527 when he fled to Siena precipitated by the Sack of Rome. Bramante had envisioned a rebuilding of St. Peters based on a Greek cross plan, and Peruzziplan suggested a variation (Allsopp, 1959). Other projects designed by Peruzzi individually or in collaboration,
in addition to St. Peters, include: fortifications near Porta Laterina and Porta S. Viene,
Palazzo Pollini, San Nicolٍ in Carpi, and the Palazzo Massimo alle Colonne in Rome. He died in
Rome in 1536, and Serlio, who included Peruzzis drawings prominently in his treatise, heralded his
influence on architecture.
This ink and wash sketch (Figure 1.3) demonstrates a three-dimensional study of what seems to be
a sepulcher, or tomb chest, with an apsidiole form. This small projecting chapel structure consists of
a self-contained entity, possibly planned for an interior wall of a cathedral side aisle. Drawn freehand
in perspective, or a version of an elevation oblique, the sketch appears somewhat distorted, obviously
not calculated or measured. Because this view employs washes for shadows and a completed composition,
Peruzzi was able to interpret and evaluate the proposed solution. The sketch, then, suggests
the importance for Peruzzi to quickly comprehend three-dimensional relationships. The sketch acted
as a method of evaluation to represent either an image from his minds eye or an emerging design
solution. Although the ink techniques are minimal and scratchy, the sketch contains enough information
to visualize the form as a whole.
Peruzzi must have understood the sketch as part of a process. Although showing the aedicule as a
whole, the technique of the lines are quick and loosely constructed, suggesting not a solution, but a
momentary snapshot of a thought in the process. The columns are straightened by additional lines in
a method of making and matching, numbers are sprinkled over the top and other façades, and pentesting
lines appear in the background (Gombrich, 1969, p. 29). These elements, which appear on and
around the sketch, suggest the little value given the image by Peruzzi after the information was conveyed
in a dialogue of the design process. Even though the columns are not straight and the distances
between the columns are irregular, the sketch conveys a compositional whole, displaying proportions,
relationships and symmetry. The ink wash provides depth that enhances the three-dimensional illusion,
helping to judge the final effects of the whole. Being both a definitive view and a design in
process, the sarcophagus/tomb-chest stand has been drawn and redrawn in a search for its relationship
to the columns and figures. This reveals how the design was still fluid and could be reevaluated when
seen in conjunction with other elements.
This sketch gave a quick proportional and compositional view to Peruzzi, allowing him to see the
whole at a decision point in his thinking
