nZeh working towards net zero energy affordable homes Information session on Energy Efficiency in the Building Sector 7th October 2013
nZeh a collaborative research project bringing together stakeholders in the sectors of Building construction Sustainable development to design, implement and monitor a prototype affordable near net-zero energy residential home
What is a net-zero energy home? An energy efficient, grid connected unit enabled to generate energy from renewable sources to compensate its own energy demand so that its net energy consumption is ZERO.
Through the study of a new build prototype affordable home, the cost implications and potential for energy efficiency within the local context is better understood. nZeh will help advance the industry’s knowledge and assist with both new constructions, retrofitting of existing buildings and the achievement of near self-sufficiency at district level where possible. LOCAL CONTEXT…….

Benefits • Direct cost savings from lower energy consumption • Better environment and quality of life • Owners of low energy houses value the non-energy benefits even more than the cost savings themselves • better air quality • higher comfort levels • a better house - easier to sell • taking responsibility for the environment and future generations
