Personalizing Energy to Achieve Positive Energy Buildings

White Paper: Energy Efficiency

By definition, a positive energy building generates more energy than it consumes. This is achieved through use of on-site renewable energy sources, such as photovoltaics, wind, and biofuels. It is, therefore, important to reduce overall energy consumption as much as possible by advanced building design, material choices, and innovative approaches to building management, including the active participation of those who work in the building.

According to estimates from the Positive Energy Building Consortium (GIE Enjeu Energie Positive), building operators can achieve an additional 20-30 percent in energy savings through innovative approaches to building use and management. In real life, two-thirds of energy consumption is the responsibility of the building operator, while occupants have responsibility for the remaining one-third. Therefore, the impact of building occupants is very significant, and positive energy buildings must be designed and managed in a way to ensure occupants are mindful about the impact of their personal energy consumption.

Occupants’ impact on energy consumption depends on three major things:
• Internal design aspects of the building, including siting of structures, aspect ratios of building height to depth, construction materials, insulation, natural lighting sources, and so on
• Use of technical equipment (heating, ventilation, cooling, windows, lighting systems, escalators, and elevators) used daily
• Additional equipment such as PC printers, network routers and switches, and office lighting
