Howland Green Business Center - Ontario

The First Building of Its Kind in Canada

The mission of Howland Green Homes Ltd. is to build beyond net-Zero. This ambition objective was achieved Markham, Ontario, Canada where the company developed the Howland Green Business Centre, a commercial building that will produce more energy than it will consume.

Dave de Sylva Eng., President of Howland Green Homes, was set on environmentally-conscious development that goes above and beyond the current building codes.

The net zero energy or zero energy standard describes a building’s ability to self-generate energy by renewable, onsite means which offset any energy it consumes. 

To go beyond net zero, or to become ‘net positive’, a building must generate more energy than needed for its annual operation. Howland Green is setting the bar high for building development, not only with regards to ensuring a clean ecological footprint but also in terms of economic and energy efficiency.

  • Insulated Concrete Forms, totaling 20.32 cm (8 in) of EPS foam insulation
