Energy and Climate Breakthroughs in the Real World – A Mixed Used Development 
in Ohio 
 
The Marina District development on the banks of the Maumee River in Toledo, Ohio, is a new high 
density residential neighborhood combined with a destination-oriented entertainment district to be 
filled with a collection of clubs, restaurants, and entertainment options along the waterfront 
providing added appeal and access to Toledo’s important boating community.  It is a major factor 
in the revitalization of the city center. The housing is available for both rental and purchase 
targeted at moderate income residents. On the surface this is an attractive example of a “new 
urbanism” development becoming increasingly popular in the USA as an alternative to the 
anonymous suburbs that have dominated development for the past fifty years. 
 
Beneath the surface, the Marina District is an example of energy and environmental excellence 
second to none. The developer, Larry Dillin, will explain how he saw the growing concerns over 
energy in the USA were becoming a major factor in customers’ decisions in the coming years and 
could be a significant source of competitive advantage in a tough real-estate market. A team 
consisting of some of the world’s leading experts in efficient construction and community energy 
services was invited to develop an energy concept for the site that would meet multiple goals.  
Among these were to substantially reduce the cost of energy for years to come, to ensure supply 
would be at least as reliable as traditional networks, and to create dramatically less greenhouse 
gases. At the same time, a project with hundreds of millions of dollars at stake in a risky real-
estate market could not afford to experiment with approaches with unacceptable commercial risks. 
Recommended energy solutions must have minimal technical risk, and be acceptable in the eyes 
of relatively conservative potential clients. Finally, the impact on construction costs should be 
minimal to ensure the modest market rents and prices could be maintained. 
 
An integrated energy plan was developed that viewed the entire development as a single energy 
object to optimize the efficiency not only of the individual buildings, but also of the various options 
for supplying heating, cooling and electricity to the entire site. The value of different measures, 
economically, technically and in terms of their potential to reduce market risk or create competitive 
advantage was balanced. Toledo has about 3,500 heating degree days and less than a third that
