Environmental and health related criteria for buildings - ANEC

IBO - Environmental and Health related Criteria for Buildings
systems already refer to nearly-zero energy buildings or plus energy buildings (see EU Eco-
Label).
Operational Energy
Demonstrate a percentage improvement of the building’s energy performance compared with
the baseline building performance rating referring to Annex G of ASHRAE Standard 90.1-
2007 (range of assessment: 1 point for 12% energy cost savings, 19 points (max.) for 48%
energy cost savings). All energy costs within and associated with the building project
(process energy, service water heating for domestic or space heating purposes, interior and
exterior lighting, air-conditioning, ventilation) have to be included.
Energy and Atmosphere EA
Prereq 1 Fundamental Commissioning of Building Energy Systems
Prereq 2 Minimum Energy Performance
Prereq 3 Fundamental Refrigerant Management
Credit 1 Optimize Energy Performance 1 to 19
Credit 2 On-Site Renewable Energy 1 to 7
Credit 3 Enhanced Commissioning 2
Credit 4 Enhanced Refrigerant Management 2
Credit 5 Measurement and Verification 3
Credit 6 Green Power 2
EA Possible points EA (of 110 total points) 35
32% (35 of 110 total points) can be awarded within the category Energy and Atmosphere.
Embodied energy (production stage)
Embodied energy in building materials is not explicitly calculated but is intended to be
reduced by resource criteria such as building reuse (maintain existing walls, floors and roof),
materials reuse, recycled content, rapidly renewable and regional materials.
Traffic-related Energy Aspects
The reduction of individual traffic is not an issue for small residential buildings (within LEED
for Homes) whereas LEED-NC 2009 (for high-rise residential buildings) evaluates alternative
transportation under Sustainable Sites SS Credit 4.1.-4.4 (divided into public transportation
access, bicycle storage and changing rooms, low-emitting and fuel-efficient vehicles and
parking capacity). Parking capacity shall meet but not exceed local zoning requirements.
7.7. DGNB
Draft Criteria – residential buildings (May 2010)
DGNB offers the most comprehensive LCA view of all systems (although some materials,
especially for HVAC systems and some stages of lifecycle (transport to and from site,
construction process on-site, reuse at the end of lifetime – cradle to cradle) are not taken into
account.
