Your new home - cost of energy = affordability
Multi-tenant Buildings -
Integrated solar thermal collectors were used in Hamburg Bramfeld, Germany primarily to pre-heat domestic hot water in this attractive housing complex built in 1995. All total, 3000 square meters (approximately 32,292 square feet) of rooftop space was used for solar collection. In addition to the solar collectors a 4500 square meter reservoir system was included to store the captured heat for later use.

Balancing Design with Demand -

Many factors must be taken into account during the initial design phase of a construction project. This is especially true in situations where numerous people will share the same space. While the overall cost of the project is paramount, the quality of life issues as well as the aesthetic aspects also weigh heavily in this process. Adding alternative energy technology to the equation brings additional complexity to the mix with almost every facet of the design being exposed to scrutiny.

One of the most intrusive requirements that solar collection imposes onto the architect is the need for large amounts of unshaded space where the sun's energy can be gathered. Typically, this translates into larger rooftops lines than what might have been chosen. The roof is then covered with solar panels  which may be considered less attractive than many other architectural treatments. In addition, the entire community will require a southern orientation which tends to create a bland homogenization of style.


The Economies of Scale -

In spite of the previously cited challenges, there are numerous advantages that can be leveraged to the homeowner and developer's betterment. Due to the nature of this type of residential neighborhood, it is possible to design long, uninterrupted roof lines that allow for continuous solar collection space. Perhaps the most extreme example of this is when additional electrical generation capacity is designed expressly for resale. This additional revenue can then be used for whatever purposes the development chooses.

Assuming that the cost to build additional generation capacity is low enough that the investment makes financial sense, it is now within the power of the development to set the cost of home ownership within their association. This is truly a disruptive mechanism as applied to the concept of affordable housing. Even more to the point, in many urban areas the ability to subsidize the cost of housing with electricity resale might now allow anyone who wishes to become a stakeholder in their community.
