The provisions of this chapter regulate the design, construction, commissioning, and operation of buildings and their associated building sites for the effective use of energy.
This chapter is intended to provide flexibility to permit the use of innovative approaches and techniques to achieve the effective use of energy.
Buildings designed on a performance basis shall comply with Sections C402.5, C403.2, C404, C405.2, C405.3, C405.5 and C405.6 of the International Energy Conservation Code and with Sections 601.4, 602, 608.6, 608.7, 608.8, 608.9, 609 and 610 of this code.
Buildings designed on a prescriptive basis shall comply with Sections C402, C403, C404 and C405 of the International Energy Conservation Code, and with the requirements of Sections 601.4, 605, 606, 607, 608, 609 and 610 of this code.
Buildings shall be provided with metering complying with Section 603, and commissioning complying with Section 611. Where required in accordance with Section 604.1, building shall be provided with automated-demand response complying with Section 604.
Where there is more than one building on a site and where a building has more than one use in the building, each building or each portion of a building associated with a particular use shall comply with Section 601.5.1 or 601.5.2, or a combination of both.
For building sites with multiple buildings, the energy use associated with the building site shall be assigned on a proportional basis to each building based on total net floor area of each building in relation to the total net floor area of all buildings on the building site.
Where energy is derived from either renewable or waste energy, or both sources located on the building site, on or in individual buildings and delivered to multiple buildings, the energy so derived shall be assigned on a proportional basis to the buildings served based on building net floor area.
Exception: Where it can be shown that energy to be used at the building site is associated with a specific building, that energy use shall be assigned to that specific building.
Where buildings have more than one use, the energy use requirements shall be based on each individual occupancy.
