【 摘 要 】

The following is a guideline for energy modeling of laboratory spaces in a building in accordance with the Energy Cost Budget method described in ASHRAE 90.1-1999 Energy Standard for Buildings Except Low-Rise Residential Buildings. For the purposes of this document, a laboratory is defined as any space requiring once through ventilation systems (recirculation of air to other spaces in a building is not allowed). To accomplish this, ventilation systems in laboratories typically provide 100% outside air to the occupied space. The guideline is structured similarly to the ASHRAE 90.1-99 standard. Only those sections being clarified or modified are discussed in the guideline; all other sections should be followed as defined in the standard. Specifically, those sections that are affected include the following: (1) 6.3.3.1 - Fan Power Limitation (modification); (2) 6.3.7.2 - Fume Hoods (modification); (3) 11.3.11 - Schedules (modification); (4) 11.4.3 - HVAC Systems (clarification); (5) 11.4.3 (h) Budget Supply-Air-to-Room Air Temperature Difference (modification); (6) 11.4.3(i) - Fan system efficiency (modification); and (7) Table 11.4.3A - Budget System Descriptions (modification). For energy efficiency measures that are not explicitly addressed by the standard, we recommend application of Section 11.5, Exceptional Calculation Methods. This guideline does not cover the details of such calculation methods.
