Although there are substantial opportunities for reducing water and energy consumption and improving sustainability of California’s multifamily housing, there are also several significant barriers.

First Costs

The most frequently cited barrier to energy efficiency adoption is “first costs.” First costs” refers to the initial investment for improvements and can include energy audits and assessments, equipment procurement, systems design and construction, testing and other activities needed to identify and implement efficiency improvements. Utility incentives such as rebates for energy efficient equipment may help reduce out of pocket costs and financing programs can help to spread those costs over the life of the improvement.

Higher Costs of Retrofits

It is generally true that the cost of retrofitting existing buildings is higher on a per measure basis than new construction. However, the benchmark should be “cost effectiveness” – i.e., will a measure pay for itself? The cost-effectiveness threshold varies, depending on the length of time that any property owner tends to hold a building. Increasingly, real estate investors are including consideration of the green profile of a building’s market value, since energy efficiency and other types of “green” and sustainable measures have the potential to increase tenancy and reduce vacancies, thereby reducing holding costs; reduce energy, water and other operating costs; and attract socially conscious tenants and investors.

Split Incentives

Multifamily housing is characterized by a mix of common spaces and tenant spaces. A signif
