The for-sale residential sector has lagged far behind the commercial, industrial and for-rent residential sectors in embracing and incorporating sustainable or “green” technology, despite increased availability of techniques and products and increased demand from investors and home buyers. Why?
Terramor, a village at Ladera Ranch, a 4,000-acre master-planned community in Orange County, California is a master-planned community sits in an acutely land-constrained and desirable market and is one of the largest photovoltaic communities in North America. The project’s master developer, DMB/Rancho Mission Viejo (“RMV”) challenged builders competing to purchase home sites in Terramor to pursue as many green innovations as possible but required that they employ green principles and materials in site planning, water conservation, energy, materials and resources (including recycling over 60% of their construction waste) and indoor environmental quality. RMV selected ten of 13 competing builders: seven of these had no previous experience with green products or practices and were able to incorporate them with varying degrees of struggle and success. And at the same time, RMV was ramping up to conduct follow-up Terramor homebuyer surveys about the green features of their homes, village and community.
Schweitzer + Associates analyzed the costs and benefits of various home-builders’ approaches to going green at Terramor as well as the value Terramor home buyers placed on green components in their homes and communities. Research from January 2005 to 2006 included in-depth, multi-level interviews with the master developer, three of ten homebuilders and six of its planning, architecture, engineering, landscape, green compliance and market research consultants. Schwietzer + Associates also conducted homebuilder surveys to which seven of the ten Terramor builders responded: Centex Homes, K. Hovnanian, MBK Homes, Pulte Homes, Shea Homes, Standard Pacific Homes and William Lyon Homes. Important lessons learned included:
- Designing and building with nature by respecting the location’s existing natural systems and features (water, topography, solar and wind orientation, climate and vegetation) not only results in a superior project but costs far less. Homebuilders experienced total net green cost premiums averaging 5% (after utility rebates and state incentives); from $2.02 to $11.40/sf for multi-family attached and $2.82 to $6.61/sf for single-family detached homes which included both direct and indirect total costs.
- With little effort to educate homebuyers on the long-term cost savings of green features, 75% of homebuyers would pay over $25 per month in their mortgage for green features; 35% were willing to pay more than $100 per month in their mortgage for green features; or $3.60 to $14.40/sf (which translates to $9,000 and $36,000 over 30 years, respectively).
This study indicates that of all the equity participants in the creation of for-sale residential product (land owner, master developer, investor, homebuilder and home owner), only the homebuilder expects a short-term hold and therefore is focused on the short-term costs and benefits. This may explain why homebuilders are the slowest to embrace green principles. They are resistant to incorporating green elements because they don’t understand them fear their higher initial cost, fail to grasp the long-term cost benefits to home owners and are unable to quantify and market these benefits effectively so as to recapture their up-front costs. With improved understanding of total costs and informed marketing, homebuilders can be rewarded for going green and will realize that green and profitability are not mutually exclusive. Buyers want green and will pay for it.
