Designing
Sustainable Buildings Designing
a sustainable building requires taking a larger
view of building design, and a different view of
the design team than is most common today.
Evaluating a building as a whole system that
operates in harmony with its natural environment
and is as energy, material, and water efficient as
possible, requires the participation of architects,
engineers, landscape architects, construction
contractors, and operations staff, all of whom may
be working independently throughout the building
design process. Common goals for efficiency and use
of the natural space in and around the building
site must be conveyed to all team
members. |

Elements
of a Sustainable Building Credit:Material
collected from the Collaborative for High
Performance Schools 1 Healthy,
safe and secure. Good indoor air
quality is essential. It requires
minimizing pollutant sources and providing
adequate ventilation and air
filtration. 2 Thermal,
visual, and acoustic comfort. Thermal
comfort means that building occupants
should not feel too cold or too hot as
they work or learn. Visual comfort
requires that quality lighting makes
visual tasks, such as reading, following
presentations, and working on the
computer, easier. Lighting for each room
should be designed, not simply
specified. Daylight and electric lights
are integrated and glare is minimized.
Visual comfort also means providing a
connection to the outdoors and visual
stimulation through the use of windows at
eye level to offer views. Acoustic comfort
means that occupants can hear one another
easily. Noisy ventilation systems are
eliminated, and the design minimizes the
amount of disruptive outdoor and indoor
noise affecting the occupants. 3 Energy
efficient. Energy-efficient buildings
save money, while conserving non-renewable
energy resources and reducing atmospheric
emissions of pollutants and green-house
gases. Heating, ventilating, and
air-conditioning (HVAC) systems use high
efficiency equipment; are right
sized for the estimated demands of
the facility; and include controls that
optimize system performance. The
buildings lighting system uses high
efficiency products; optimizes the number
of fixtures in each room; incorporates
control devices that ensure peak system
performance; and successfully integrates
electric lighting and daylighting
strategies. The walls, floors, roofs, and
windows of the building are as energy
efficient as cost effectively possible.
The building shell is integrated and
optimizes insulation levels, glazing,
shading, thermal mass, air leakage, and
light-colored exterior surfaces to
minimize the use of the HVAC
systems. |
