How much space does a person need to live comfortably? Not that much, according to tiny home enthusiasts. And tiny homes are certainly one way to combat the increased demand for affordable homes in urban areas. The students of Laney College in Oakland, California, have designed and built a solar-powered net-zero tiny home to help […]
With all the talk about the need for greater sustainability, itâ€™s nice to things actually being done in that direction. Dwell Development has recently completed a small, sustainable home community called New Rainier Vista. […]
It has now been a year since the Net-Zero Energy Residential Test Facility (NZERTF) in Washington DC has been built and its energy harvesting capabilities began to be monitored. The home was built on the campus at the National Institute of Standards and Technology (NIST), where scientists and researchers conducted a computer simulation that replicated the energy consumption of a family of four. The results showed the home to be a success, since after a year the home generated 13,577 kWh of energy. This is about 491 kWh more than was needed.
Last week, the Zero Net Energy (ZNE) house was unveiled in Clovis, California. The three-bedroom, two-bathroom home has a living area of 2,064 square-feet and was built as a join effort between BIRAenergy Consulting and De Young Properties. Pacific Gas and Electric (PG&E) offered technical assistance to the builders in trying to find ways of getting the home to use only one-third of the energy needed for a house built to minimum code. ZNE House was built to become a model for future net zero homes in the area.
The house features numerous energy-efficiency improvements, which are in accordance with Californiaâ€™s Long-Term Energy Efficiency Strategic Plan. This plan stipulates that all new residential construction in California will be net-zero by the year 2020. The house will not be made available for purchase yet, as it will serve as a prototype to study how well it functions and what improvements have yet to be made.
A Miami Beach home, located at 2020 Alton, has been awarded LEED Platinum, with the score of 120/89.5. The project is a joint effort of developer Matthew Lahn of the Florida Green Home Design Group, architect Ari Sklar of Sklarchitecture, and general contractor Robert Arkin. The project also has an -8 HERS score, has been named an Energy Star Qualified Home, and has received the National Green Building Standard Emerald rating, which indicates that the house saves 60% or more of its energy use.
Vermont-based Vantem Panels, one of the United Statesâ€™ first producers of SIPs (structural insulated panels) and one of three American producers of urethane panels, has released the first affordable net-zero energy kit homes: SmartHomze.
With an estimated $150 per square foot cost of construction (not including permits, site work, or foundation), SmartHomze are significantly more affordable than typical green homes that range between $200 and $250 per square foot and more in line with construction costs for an average new home that doesnâ€™t include sustainability features.
