Business case for building green
Design & construction costs
Operating costs
Risk mitigation
The report, “The Business Case for Green Building: A Review of the Costs and Benefits for Developers, Investors and Occupants,” examines whether or not it’s possible to attach a financial value to the cost and benefits of green buildings. Today, green buildings can be delivered at a price comparable to conventional buildings and investments can be recouped through operational cost savings and, with the right design features, create a more productive workplace. This report http://www.worldgbc.org/activities/business-case/ was produced in partnership with PRP Environmental along with the following sponsors: Skanska, Grosvenor, and the Abu Dhabi Urban Planning Council/Estidama.

By greening our built environment at the neighbourhood and city scales, the green building industry can deliver on large-scale economic priorities such as climate change mitigation, energy security, resource conservation and job creation, long-term resilience and quality of life.
There has been an overall trend towards the reduction in design and construction costs
associated with green building as building codes around the world become stricter, supply
chains for green materials and technologies mature and the industry becomes more skilled
at delivering green buildings
Green buildings have been shown to save money through reduced energy and water
consumption and lower long-term operations and maintenance costs. The energy savings alone typically exceed any cost premiums
associated with their design and construction within a reasonable payback period
Sustainability risk factors can significantly affect the rental income and the future value of real estate assets, in turn affecting their return on
investment. Regulatory risks have become increasingly apparent in countries and cities
around the world, including mandatory disclosure, building codes and laws banning
inefficient buildings

Why build, lease or own green?
Source: World Green Building Council – The Business Case for Building Green, A Review of the Costs and Benefits for Developers, Investors, and Occupants
With so many drivers for green buildings at play, and many parts of the world still at the nascent phase of green building, there can be no doubt that the business case for green building will continue to evolve as markets mature. Green building is something that tenants, investors and policy makers will come to demand and expect over time – indeed we have already seen this momentum grow globally where in more and more places, green is now becoming the status quo.

Rental income decrease
Future value of real estate assets
Regulatory risks; mandatory disclosure, building codes and laws banning inefficient buildings.
Resilience to Extreme weather events and insurability to climate change
Changing tenant preferences and investor risk screening may translate into risk of obsolescence for inefficient buildings.
Sustainability represents an assortment of risks and possible rewards for real estate investors.

EDGE : Adaptation groups used for classification of embodied energy in construction materials •Energy-intensive, high cost materials, such as aluminum, steel and glass.
•Both electricity and fuel sources used have a significant influence on the impact, as do the efficiency of the process and the use of recycled content. Group 1
•Fuel-intensive, lower cost materials, such as cement , bricks and kiln-dried timber. Fuel source and technology significantly affect the impact. Group 2 •Input-related products such as concrete blocks and gypsum –based products ,where the input materials such as cement & gypsum have the greatest effect on
impacts.
•Use of alternative raw materials such as ground granulated ballast furnace slags (GGBS), pulverized fuel ash (PFA) or flue gas desulfurized (FGD) gypsum has a strong influence over impacts.
Group 3
•Electricity-intensive, high cost goods such as flooring and board products. Electricity source and recycled content have the most influence on impacts. Group 4
•Low- cost, less-processed products such as aggregates, straw, etc. These materials are generally produced locally, with predictable production processes and lower impacts. Group 5
