Personalizing energy as part of achieving positive energy buildings TableofContents Thepositiveenergybuilding....................2 EmployeebehaviorandIT.........................3 PositiveimpactofIT...................................4 Monitoringgroupand personalenergy...........................................5 Energyefﬁcient computingtechnologies.............................6 INTRODUCTION 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. See ﬁgure one.

Internal design aspects of the building, including siting of structures, aspect ratios of building height to depth, construction materials, insulation, natural lighting sources, etc 2. Use of technical equipment (heating, ventilation, cooling, windows, lighting systems, escalators and elevators) used daily 3. Additional equipment such as PC printers, network routers and switches, and ofﬁce lighting In a commercial ofﬁce building, the energy consumption of personal computing and printing can play a big role in overall “plug loads”, so astute building managers and CIOs pay close attention to providing employees with information about their computing energy footprint, as well as selecting the right computing model matched to the nature and strategy of the business. So, what is the right conﬁguration and type of personal computer? What is the impact on employee productivity? What is the impact on comfort? What is the impact on electricity consumption? What is the right security level? What is the cost to the company in both capital expenses and operating expenses? Based on the learnings from Green Ofﬁce* quantitative studies, this document explores some of these questions and showcases an innovative approach to personalizing energy.

In order to be labeled as a positive energy building, the building needs to produce more energy than it consumes. Green Ofﬁce® consumption will be 62 kWH/m2/year, yet it will produce 64 kWH/m2/year of renewable energy. See ﬁgure two.
