地区住宅建筑商协会与水、天然气和电力公用事业公司成立了一家合资企业，旨在建设一个理想的节水节能住宅，由此产生了一种新型的建筑商项目。通过结合关键词经济、H20和能源，ECH20能源的名称为科罗拉多州丹佛项目而生。该项目得到了地区贷款机构的认可，帮助支撑了低迷的建筑市场，并为更多潜在买家提供了购房机会。包括人物、照片。

A joint venture by the area homebuilders association and the water and natural gas and electricity utilities for the purpose of constructing an ideal water and energy-conserving home resulted in the creation of a new kind of builders' program. By combining the key words economy, H20, and energy the ECH20NERGY name was born for the Denver, Colorado program. Accepted by area lenders, the program helped buoy a sagging construction market and provided more potential buyers with the opportunity to purchase a home. Includes figure, photographs.
