TRIPLE BOTTOM LINE
PLANET: Impact on air, water, land and global climate.
PEOPLE: Impact on a person happiness, health, and productivity
PROFIT: impact on a corporation’s bottom Line

THE BUSINESS CASE FOR GREEN BUILDINGS
33 Green Buildings in California
$150-$250 Cost/ft2 20 years Life time

The Costs and Financial Benefits of Green Buildings
O&M SAVINGS
ENERGY SAVINGS
HEALTH & PRODUCTIVITY
EMISSIONS SAVINGS
WATER SAVINGS
5
ENERGY SAVINGS
Integrated Design High performance lighting Increased ventilation effectiveness Commissioning Heat Island reduction measures
Supply optimization - optimized utility systems capacity
On-Site generation
DEMAND SIDE SUPPLY SIDE
$0.025/ft2/yr $0.44/ft2/yr
20yr PV OF ENERGY SAVINGS
$5.79/ft2
Key assumptions/limitations: • 10% peak demand reduction by
green buildings. • 30% energy use reduction in green
buildings. • Average Building energy use of 10
kWh/ft2 per year
6
EMISSIONS SAVINGS
$0.044/ft2/yr
20yr PV OF EMISSIONS SAVINGS
$1.18/ft2
Key assumptions/limitations: • Average Building energy use of 10 kWh/ft2
per year • 36% emissions reduction in green buildings. • CO, ROCs, and VOCs are not evaluated. • Market values for traded emissions are used
in the calculations.
Air pollutants associated with energy and burning of fossil fuels
NOx
principal cause of smog.
PM10
principal cause of respiratory illness &
contributor to smog
SO2 or SOx principal cause
of acid rain
CO2
principal greenhouse gas
$0.005/ft2/yr $0.033/ft2/yr $0.013/ft2/yr

WATER SAVINGS
Efficiency of potable water use through better design/technology.
Better leak detection. More efficient appliances. Aggressive audits
Gray water use Storm water use Recycled/reclaimed water
use
DEMAND SIDE SUPPLY SIDE
20yr PV OF WATER SAVINGS
$0.51/ft2
Key assumptions/limitations: • Water cost assumed to include: Fresh water price. Sewerage treatment price. Marginal costs associated with: Water supply expansion and treatment. wastewater capacity and treatment. Impact of climate change on the cost of
future water supplies.

HEALTH & PRODUCTIVITY SAVINGS
Green buildings attributes correlated to increased productivity
20yr PV OF Health & Productivity SAVINGS
$36.89/ft2
Key assumptions/limitations: • Employee cost is 10 time the cost of
space per employee and therefore 1% productivity increase will reduce property costs by 10%
• Assumed employee cost is $66,478 and space cost $6.477

Key assumptions/limitations: • Assumed O&M costs = 12.25/ft2/yr or
$3,039 per person per year
Commissioning

Buildings meet and maintain
performance targets.
better management of upgrades and
maintenance through anticipation of
equipment failure, leaks

GAP REASONS
People are still hooked to the historical data – Green Costs are coming down for 3 reasons
105 Suppliers and Manufacturers from 27 countries
Have Green characteristics in their products 70% Have products made of recycled
content and/or are non-toxic 50%
McGraw hill construction (2013)
1 Supply Chain is getting mature
Life Cycle data provided 30%

RECOMMENDATIONS
1. A similar study to that of state of California should be done in the GCC region to confirm its findings within our local context.
2. Municipalities should encourage building green by passing 50% of the estimated 10 times ROI of building green to developers/owners in the form of incentive programs and subsidizing schemes.
3. EDUCATION..EDUCATION...EDUCATION…. the more people know about the benefits of building green, the more feasible it becomes: • Knowledgeable professionals = more efficient designs • Knowledgeable policy makers = More holistic green regulations • Knowledgeable suppliers = Green products benefits communication • Knowledgeable end users = better green buildings rental premiums
