加利福尼亚州(美国)

总结、概要

CCR 是加州制定的州级规范,符合或超出IECC2009和ASHRAE 2007标准要求,是针对所有新建住宅和非住宅建筑的强制性规范。该规范对建筑外围的热性能,和HVAC、热水、照明及其辅助系统的能效提出了要求。该规范允许使用法条式规范方式或能源预算方式以证明改建或增建符合规范要求。CCR的2012年版即将公布。

加州在制定建筑物能效标准方面具有悠久历史。从1978年至今,建筑能效规范得到持续改善,并计划在2013年进一步强化能效要求。现行规范及其辅助支持体系包括一些改善能效的动态行动计划,包括时间依赖型估价、地方政府提高能效要求,HERS的认证计划、“太阳能准备”建筑计划、商业建筑能源基准制定以及制定公共建筑特殊要求。

规范设置在:

地区/州/省 水平

范围

建筑规范的范围:

  • 住宅建筑
    • 单户
    • 多户建筑
      • Time Dependent Valuation (TDV), provides the foundation for Title 24 calculations. TDV applies an hour-by-hour factor and reflects the life cycle value of energy savings, time of year, climate zone, type of fuel, building type and outdoor temperature.
  • Commercial buildings
    • 写字楼
    • 零售与批发
    • 酒店
    • Hospitals
    • 教学楼
  • Public buildings
    • Offices
    • 医院
    • Educational buildings
  • 所有城市建筑

GBPN气候分类:

  • 供暖型
  • 16 Climate Zones - Between heating based and a mixed climate.

建筑规范的类型

建筑规范的类型:

  • 样板规范、框架或实际规范:
    Statewide Code.
  • 法条规范:
    Prescriptive approach can be used for both types of buildings, including requirements for building envelopes, space-conditioning systems, service water-heating systems, lighting systems, outdoor lighting systems and Interior and exterior signs.
  • 能耗声明:
    Partially, in most cases this requirement is only voluntary at this stage. The idea is being developed, public proceddings underway - San Francisco City has a disclosure program where energy declaration is required for certain buildings.
  • 样板/参考建筑:
    Energy Budgets (reference building) for a proposed building is the sum of the space-conditioning, lighting, and service water-heating budgets expressed in Btu/sf/a. Applicable to residential and non-residential buildings and alterations or additions.

涉及的能源

能源要求的基础:

  • 总体性能框架:
    Time Dependent Valuation (TDV). Under TDV the value of electricity differs depending on time-of-use (hourly, daily, seasonal), and the value of natural gas differs depending on season.
  • 终端能源:
    Partially, calculation is for 'Site' energy.
  • 寿命周期评估(隐含能源):
    Partially , not for individual buildings, but within Part 6 there are requirements for when an individual measure is undertaken, a cost optimal analysis is required for that system, including; first cost, ongoing costs, lifecycle savings.

建筑规范包括的能源消耗和功能:

  • 供暖
  • 制冷
  • 通风
  • 气密性
  • 热桥
  • 热水
  • 建筑物组成部分(电梯、水泵等)
  • 技术装置
  • 照明
  • 电器
  • 建筑的设计、位置和朝向
  • 自然通风
  • 遮阳
  • 日光照明要求
  • 可再生能源 (太阳能、光伏等):
    Renewable systems can be used to offset expected energy use when completing energy calculations for compliance. Many city only codes have increased requirements for renewable energy. No minimum requirements.

规范历史和未来目标

设定要求的一般流程:

  • 未来目标制定提前多长时间?:
    0
    2020 for residential and 2030 for commercial
  • 利益团体提前很多时间得到未来目标的通知。

零能耗目标:

  • 近零能耗/零能耗/正能耗的定义:
    The amount of energy provided by on-site renewable energy sources is equal to the amount of energy used by the building.
  • 包括所有的终端用能设备
  • 没有准备好现实的路线图
  • 全国达到近零能耗目标日期:
    State target, residential by 2020 and commercial by 2030 - all new commercial buildings and half of the existing commercial building stock be nZEB by 2030 (energy use will need to decrease by 60-70%). These targets are policy at this stage, not regulation or law.
  • 公共建筑特殊要求:
    State buildings and build-to-suit leases larger than 10,000 square feet obtain LEED “Silver” or higher. State agencies, departments, and other entities under direct executive authority take actions to reduce entity-wide greenhouse gas emissions.

支持措施

是否有 鼓励人们超最低要求的激励措施/奖励?

There are many programs available, these include City Green Building Incentives (San Diego & Santa Monica), Local Rebate Programs, PACE financing, Performance Based Incentives, State Rebate Programs, Utility Grant Programsand Utility Rebate Programs.

利益相关群体参与规范制定

A very open public process, development partners are utilities, they have a lot of involvement in the process. Meetings are called with stakeholders, the new measures are presented to the various stakeholders.

在规范实施后提供给利益相关群体的培训水平?

The energy commission provides an online learning center and for each code update, utilities offer a series of seminars and workshops in each region, covering lighting, HVAC, envelope and simulation tools, the training are predominantly free.

向普通大众提供合适的信息

Websites, seminars, courses etc.
