ENERGY CONSERVATION

1 2PROJECT:
JAN,2009
ENERGY CONSERVATION IS THE PRACTICE OF DECREASING
THE QUANTITY OF ENERGY USED. IT MAY BE ACHIEVED
THROUGH EFFICIENT ENERGY USE, IN WHICH CASE ENERGY
USE IS DECREASED WHILE ACHIEVING A SIMILAR OUTCOME,
OR BY REDUCED CONSUMPTION OF ENERGY SERVICES.
ENERGY CONSERVATION WILL RESULT IN INCREASE OF
FINANCIAL CAPITAL, ENVIRONMENTAL VALUE, NATIONAL
SECURITY, PERSONAL SECURITY, AND HUMAN COMFORT.
INDIVIDUALS AND ORGANIZATIONS THAT ARE DIRECT
CONSUMERS OF ENERGY MAY WANT TO CONSERVE ENERGY
IN ORDER TO REDUCE ENERGY COSTS AND PROMOTE
ECONOMIC SECURITY. INDUSTRIAL AND COMMERCIAL USERS
MAY WANT TO INCREASE EFFICIENCY AND THUS MAXIMIZE
PROFIT.

VEGETATED ROOFING
Vegetated roofing is one of the
most exciting developments in
sustainable building
design. Depending on load
capabilities and other application-
driven requirements, green roofs
can be planted with herbs, grasses,
flowers, even trees, in an exciting
variety of colors, textures, scents
and heights. Patios and walkways
can become a useable part of the
roof environment.
Insulating qualities mean
reduced energy costs for building
owners

Reduce storm water run-off which
in turn, reduces the stress on urban
sewer systems and decreases run-off
related pollution of natural
waterways .
Air quality improvement – lower
rooftop temperatures mean less
smog from the “urban heat island
effect.”
Noise pollution reduction – studies
show noise levels in a building can
be reduced by as much as 40
decibels
Extended life of the roof system due
to moderated temperature swings
that cause a roof system to expand
and contract as well as protection
from everyday wear and tear.

EXTERIOR SOLAR CONTROL
THE GENERAL CONCEPT IS TO INTERCEPT DIRECT SUN
BEFORE IT ENTERS THE BUILDING. ONCE DIRECT SUN ENTERS
THE BUILDING, THE ONLY WAY IT CAN GET BACK OUT IS
THROUGH REFLECTION OR INDIRECTLY BY CONVECTION
AND LONG-WAVE RADIATION.
LOUVERS AND BLINDS ARE COMPOSED OF MULTIPLE
HORIZONTAL OR VERTICAL SLATS. SLATS CAN BE EITHER FLAT
OR CURVED. WITH DIFFERENT SHAPE AND REFLECTIVITY,
LOUVERS AND BLINDS ARE USED NOT ONLY FOR SOLAR
SHADING, BUT ALSO FOR REDIRECTING DAYLIGHT.
WHILE FIXED SYSTEMS ARE DESIGNED MAINLY FOR SOLAR
SHADING, OPERABLE SYSTEMS CAN BE USED TO CONTROL
THERMAL GAIN, REDUCE GLARE, AND REDIRECT SUNLIGHT.

1 35PROJECT:
JAN,2009
OPERABLE SYSTEMS (WHETHER MANUAL OR
AUTOMATICALLY CONTROLLED) PROVIDE MORE FLEXIBILITY
BECAUSE THE BLINDS CAN BE RETRACTED AND TILTED,
RESPONDING TO THE OUTDOOR CONDITIONS.
LOUVERS AND BLINDS PERFORM WELL IN ALL CLIMATES.
FOR COMMERCIAL BUILDINGS IN HOT CLIMATES, THE
SYSTEM MAY BE MORE ENERGY-EFFICIENT IF PLACED ON
THE EXTERIOR OF THE BUILDING WHILE BLOCKING SOLAR
RADIATION. FOR BUILDINGS IN COLD CLIMATES, THE SYSTEM
CAN BE USED TO PROVIDE MORE DAYLIGHT AND ABSORB
SOLAR RADIATION.

These are essentially constructed

placed in a median strip between

Depending on the setting, they
may be confined to narrow cross-

capacity to low intensity storms.
Raised medians can be retrofitted
by excavation and curb cuts to
allow water to enter.

BIO (VEGETATED) SWALES
A VEGETATED SWALE IS A BROAD
,SHALLOW, TRAPEZOIDAL OR
PARABOLIC CHANNEL, DENSELY
PLANTED WITH A VARIETY OF
TREES, SHRUBS, AND GRASSES. IT
IS DESIGNED TO ATTENUATE AND
IN SOME CASES INFILTRATE
RUNOFF VOLUME FROM
ADJACENT IMPERVIOUS
SURFACES, ALLOWING SOME
POLLUTANTS TO SETTLE OUT IN
THE PROCESS.

1 47PROJECT:
JAN,2009
A VEGETATED SWALE IS AN ALTERNATIVE TO STANDARD BELOW GROUND
STORM WATER SEWERS.
THEY INTERCEPT OR RECEIVE IMPERVIOUS SURFACE RUNOFF AND BLEND
INFILTRATION AND SLOW CONVEYANCE OF STORM WATER.
THE SOIL MATRIX OF THE SWALE CAN BE AMENDED TO ENHANCE
INFILTRATION AND PERCOLATION.

1 48PROJECT:
JAN,2009
THESE SYSTEMS CAN BE ENGINEERED TO ABSORB THE HIGH FREQUENCY
LOW INTENSITY STORMS BUT CAN CONVEY THE LARGE STORM EVENTS WHILE
PROVIDING VEGETATIVE FILTERING.
BIO SWALES CAN DISCHARGE TO GROUNDWATER, STORM SEWER INTAKES,
OR DIRECTLY TO SURFACE WATER.

1 49PROJECT:
JAN,2009
GRASS SWALE
GRASS SWALES ARE ESSENTIALLY CONVENTIONAL DRAINAGE DITCHES. THEY
TYPICALLY HAVE MILDER SIDE AND LONGITUDINAL SLOPES THAN THEIR
VEGETATED COUNTERPARTS. GRASS SWALES ARE USUALLY LESS EXPENSIVE
THAN VEGETATED SWALES. HOWEVER, THEY PROVIDE FAR LESS INFILTRATION
AND POLLUTANT REMOVAL OPPORTUNITIES. GRASS SWALES ARE TO BE USED
ONLY AS PRETREATMENT FOR OTHER STRUCTURAL BMPS.

1 50PROJECT:
JAN,2009
WET SWALE
WET SWALES ARE ESSENTIALLY LINEAR WETLAND CELLS. THEIR DESIGN OFTEN
INCORPORATES SHALLOW, PERMANENT POOLS OR MARSHY CONDITIONS
THAT CAN SUSTAIN WETLAND VEGETATION, WHICH IN TURN PROVIDES
POTENTIALLY HIGH POLLUTANT REMOVAL. A HIGH WATER TABLE OR
POORLY DRAINED SOILS ARE A PREREQUISITE FOR WET SWALES. THE
DRAWBACK WITH WET SWALES, AT LEAST IN RESIDENTIAL OR COMMERCIAL
SETTINGS, IS THAT THEY MAY PROMOTE MOSQUITO BREEDING IN THE
SHALLOW STANDING WATER. INFILTRATION IS MINIMAL.

1 51PROJECT:
JAN,2009
DRY SWALE WITH FILTER MEDIA
THE DRY SWALE (OR BIO-SWALE)
CONSISTS OF AN OPEN CHANNEL THAT
HAS BEEN MODIFIED TO ENHANCE ITS
WATER QUALITY TREATMENT CAPABILITY
BY ADDING A FILTERING MEDIUM
CONSISTING OF A SOIL BED WITH AN
UNDER DRAIN SYSTEM. THE DRY SWALE
SYSTEM IS SIZED TO ACCEPT THE ENTIRE
WQV AND ALLOW IT TO BE FILTERED
THROUGH THE TREATMENT MEDIUM
AND/OR INFILTRATE THROUGH THE
BOTTOM OF THE SWALE. THE DRY SWALE
SYSTEM IS DESIGNED TO DRAIN DOWN
BETWEEN STORM EVENTS WITHIN ABOUT
ONE DAY. SINCE THIS SYSTEM IS DRY
MOST OF THE TIME, IT IS THE PREFERRED
SYSTEM FOR RESIDENTIAL APPLICATION.

1 52PROJECT:
JAN,2009
THE MOST EFFECTIVE METHOD TO MINIMIZE STORM WATER RUNOFF
VOLUME IS TO REDUCE THE AMOUNT OF IMPERVIOUS AREA.
TO MINIMIZE IMPERVIOUS SURFACES AND TO ENCOURAGE THE NATURAL
PROCESS OF EVAPORATION AND INFILTRATION, CONSIDER SUCH METHODS
AS INSTALLING GREEN ROOFS AND PAVING WITH PERVIOUS MATERIALS.
STORM WATER MANAGEMENT PLAN
THE STORM WATER DRAINAGE SYSTEM SHOULD BE DESIGNED SUCH THAT
80% OF AVERAGE ANNUAL TSS (TOTAL SUSPENDED SOLIDS) ARE REMOVED.
ANY STORM WATER LEAVING THE SITE SHOULD BE TREATED BEFORE LETTING
INTO THE MUNICIPAL DRAIN. RAINWATER HARVESTING SYSTEM SHOULD
INCORPORATE FILTRATION MEDIA TO REDUCE TSS LEVEL. (LEEDS
