Abstract The utilisation of natural energy not only can reduce consumption in buildings but also lower carbon emissions from the use fossil fuel for building services. It is believed that with appropriate design and a good attitude users, role renewable reducing will be maximised. This study proposed implementation Zero Energy Buildings (ZEB) concept initial stage by considering buildings’ form...

Over the past 20 years, net-zero energy house (NZEH) construction costs have steadily decreased because of many reasons, such as technical progress, energy-saving design obligations, and dramatic cost reductions in renewable systems, especially solar power systems. Currently, NZEH are estimated to be about 5% higher than similar-sized houses. These additional mainly for installing PV which can ...

A 2715 ft2 (252 m2), two story, residential home of the style typical of the Gaithersburg, Maryland area was constructed in 2012 to demonstrate technologies for net-zero energy (NZE) homes (or ZEH). The NIST Net-Zero Energy Residential Test Facility (NZERTF) functions as a laboratory to support the development and adoption of cost-effective NZE designs, technologies, construction methods, and b...
