Howland Green Business Center - Ontario

Howland Green Homes Ltd. new mission is simple: Build Beyond Net-Zero. This objective is to be realized in the City of Markham, where the company has developed the ‘Howland Green Business Centre,’ a commercial building that will produce more energy than it will consume. “THE FIRST BUILDING OF ITS KIND IN CANADA”

For Dave de Sylva Eng., President of Howland Green Homes, the future is now. This set a whole new standard for environmentally conscious development that goes above, and beyond the current objectives, Canadian developers must meet.

The ‘Net Zero’ energy standard describes a building’s self-generating ability to produce energy by renewable, onsite means. This practice has been increasingly realized in Ontario by several developers, and Howland Green is a pivotal example of such developments in the GTA.

To go beyond Net Zero, or to become ‘Net Positive’ a building must generate more energy than needed for its annual operation. Howland Green ‘raises the bar’ in development practice, not only with regards to ensuring a clean ecological footprint but also in terms of economic efficiency by reducing high energy-related costs with less efficient buildings.
