英格兰 & 威尔士

总结、概要

L1A和L2A规范都属于强制性、绩效型建筑规范。该规范要求进行能源框架计算以确定设计排放率(DER)不会超过由相同形状和规模的参考建筑物产生的目标排放率(TER)--排放值是用千克CO2作计量单位。此规范将围护热工性能要求和耗能系统 (包括HVAC、热水、照明、生物气候设计和可再生能源等)纳入有关计算。

英格兰和威尔士自1976年起就制定了指定型建筑能效要求。在2002年实施 EPBD后,英格兰和威尔士于2005年颁布首部绩效型建筑规范。2010年版规范和相关国家政策被进一步强化以满足EPBD修订后的要求。这包括强制(参考建筑物)模拟计算、气密性测试、热桥和再生能源要求、入住前调试以及所有新建住宅在2016年前达到零碳排放的国家目标。

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:
    National Code.
  • 翻新建筑性能规范:
    Partially for Dwellings and Non-dwellings.
  • 新建建筑性能规范:
    The L1A and L2A are mandatory performance-based codes that require an energy frame calculation to establish that the Design Emissions Rate (DER) does not exceed the Target Emissions Rate (TER) - measured in kg CO2 for a notional building of the same shape and size.
  • 能耗声明:
    Display Energy Certificates (DECs) are produced by public authorities and institutions providing public services to large numbers of persons where they occupy buildings with floor areas greater than 1,000 m2. Commercial Energy Performance Certificate must be submitted to building control before a completion certificate can be issued.
  • 样板/参考建筑:
    The L1A and L2A are mandatory performance-based codes that require an energy frame calculation to establish that the Design Emissions Rate (DER) does not exceed the Target Emissions Rate (TER) measured in kg CO2 for a notional building of the same shape and size.

涉及的能源

能源要求的基础:

  • 总体性能框架:
    The calculated rate of CO2 emissions from the dwelling or non-dwelling must not be greater than the TER. The code includes particular requirements surrounding calculation procedures for different fuel types and systems.
  • 一次能源:
    Partially - Co2 emissions are calculated.

建筑规范包括的能源消耗和功能:

  • 供暖
  • 制冷
  • 除湿
  • 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
  • 被动式太阳能
  • Passive cooling
  • 自然通风
  • 遮阳
  • 日光照明要求
  • 可再生能源 (太阳能、光伏等):
    Provided the dwelling satisfies the limits on design flexibility as set out in Criterion 2, the compliance procedure allows the designer full flexibility to achieve the TER utilising fabric and system measures and the integration of low and zero carbon (LZC) technologies in whatever mix is appropriate to the scheme. The approved compliance tools include appropriate algorithms that enable the designer to assess the role LZC technologies.

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?:
    2015
    2015, 2018, 2020
  • 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 definition of zero carbon is not yet finalised.
  • 不包括所有的终端用能设备
  • 没有准备好现实的路线图:
    Not known at this stage.
  • 全国达到近零能耗目标日期:
    In 2006, the Government declared its ambition of “a target for all new homes to be zero carbon within a decade”. A high level “2016 Taskforce” was set up by Government, together with a “Zero Carbon Hub4” to support and report to the Taskforce.

多重数据组:

  • Levels beyond minimum:
    Dwellings EPC provides a rating of the overall energy efficiency of the building on a scale from A to G. Non Dwelling EPC Content - Energy performance is shown as a single CO2 based index, on a scale of A to G and an asset rating calculation.
  • Year historic or aspirational codes (planned) :
    2015
  • Baseline (actual code if nothing else):
    2009
  • 预期能耗的实际消耗
    • Relative target in percent:
      70
  • Primary Energy Performance Frame Residential:
    The “built performance” emissions from new homes should not exceed: 10 kg CO2(eq) /m2/year for detached houses; 11 kg CO2(eq) /m2/year for other houses; 14 kg CO2(eq) /m2/year for low rise apartment blocks.

支持措施

是否有 鼓励人们超最低要求的激励措施/奖励?

Dwellings constructed to achieve net carbon emissions of zero over the year are exempt from stamp duty tax. Feed-in tariffs (FiTs) have been introduced from April 2010 for electricity generated on site from small-scale renewable electricity generating systems (<5MWe), see link at left. The Government has indicated that a similar Renewable Heat Incentive (RHI) will be introduced from June 2011.

在规范实施后提供给利益相关群体的培训水平?

Major publicity campaigns have taken place in all parts of the UK through a range of media: TV, press, radio, the internet and guidance documentation for householders and other stakeholders. The regional governments have worked with Professional Bodies, Trade Associations and Accreditation Schemes to ensure a smooth implementation process.
