CASE STUDY PARAMETERS
The case study quantifies the cost premium for LEED Gold above the cost of a doing the same
hotel on the same site without pursuing LEED. For example the credit for Public Transportation
Access was considered zero cost because the site met the requirement. However, the Bicycle
Storage and Changing Room credit called for program space and equipment not typically in the
program, therefore a cost was accessed. Both hard and soft costs were analyzed. Incentives
and utility cost reduction paybacks were also factored in.
RESULTS
The final analysis shows a 1.2% soft cost & hard cost premium to the project to pursue LEED Gold.
After factoring in the Oregon incentives, the premium is eliminated. The energy and water conservation
measures continue to pay back approximately $60,000 in savings each year. After 10 years, the
property will save over $675,000 dollars in operating costs. Isolating the cash outflows and inflows
related to LEED, the project realizes a 28.8% return on investment for funds spent on green initiatives.
The property will benefit from a 30% reduction in energy costs and 26% reduction in water and
sewer charges. It will also provide a healthy indoor environment to guests and employees. The
green initiatives that will be achieved and verified via LEED certification will set the property apart
from others. It will give the property the ability to gain market share from the growing number of
groups and individuals who are concerned about the environmental performance of the hotels
they choose.
