Environmental and health related criteria for buildings - ANEC

IBO - Environmental and Health related Criteria for Buildings
Embodied Energy in Building Materials
The embodied energy in building materials is neither reflected within the energy section nor
directly within the material categories.
The first criterion Mat 1: “Environmental Impact of Materials” assesses only impact
categories (e.g. Global Warming Potential, Ozone Depletion Potential, Human Toxicity,
Ecotoxicity to Water/Land, Nutrification Potential,..) and resource indicators such as water or
mineral resource extraction. The consumption of renewable or non-renewable energy
sources by production processes of building materials is not considered (for more details see
chapter “Life Cycle Assessment (LCA)”).
GWP of insulations
Besides Green Guide rating of the building elements in Mat1, the Global Warming Potential
(GWP) of insulations is rated separately under Pollution 1.
The credit must be withheld if one of the insulating materials (for roofs, walls, floors, hot
water cylinder, pipe insulation, cold water storage tanks and external doors) uses substances
which have a GWP ≥ 5 kg CO 2 -equiv./kg. This requirement concerns foamed thermal and
acoustic insulating materials manufactured outside the EU as such substances are prohibited
within the Member States.
7.6. LEED rating systems (LEED for Homes / LEED-NC v2009)
The LEED rating systems are designed for rating new and existing commercial, institutional,
and residential buildings. Each rating system is organized into 5 environmental categories:
Sustainable Sites, Water Efficiency, Energy and Atmosphere, Materials and Resources, and
Indoor Environment Quality. An additional category, Innovation in Design, addresses
sustainable building expertise as well as design measures not covered under the 5
environmental categories. Regional bonus points are another feature of LEED and
acknowledge the importance of local conditions in determining best environmental design
and construction practices.
LEED® for Homes which is only applicable for small residential buildings (up to three
storeys) assesses energy-related indicators under the main category “Energy and
Atmosphere EA”.
There are two different pathways to show compliance with the requirements:
- “energy performance approach”: ENERY STAR® 28 labelled house (EA1.+EA7.+EA11.)
or
- “prescriptive approach”: comprising individual measures and including all prerequisites
of EA2.-EA10
Energy performance approach:
- EA1. Optimize Energy Performance:
28 ENERGY STAR is a government-industry partnership managed by the U.S Environmental Protection Agency
and the U.S. Department of Energy. The program’s website offers energy management strategies, benchmarking
software tools for buildings, product procurement guidelines, and lists of ENERGY STAR-qualified products and
buildings. http://www.energystar.gov
