SGBC EVALUATION CRITERIA FOR GREEN BUILDING PRODUCT CERTIFICATION

FAÇADE AND ROOF SYSTEMS: PAINTS AND COATINGS

1. INTRODUCTION

1.1 Purpose

This document aims to establish a set of evaluation criteria for Paints and Coatings under the product certification category of Façade and Roof Systems. The primary purpose is for Singapore Green Building Council (SGBC) to use the criteria for green building product certification, and support the development of Building and Construction Authority (BCA) Green Mark Scheme.

1.2 Background Environmental impact from paint products and coating materials is due mainly to the individual paint components and the manufacturing process itself. Paint products can have significant impact on the environment throughout their lifecycle – from the release of environmentally harmful substances during manufacturing process, when paints are being applied, from the paint surface itself during their useful life and when unused paint is disposed or in paint removal. Significant contributions to the energy consumption, global warming and environmental pollution of paint and coating materials come from their 3 main components: pigments, volatile organic solvents (VOC) and binders. Their impacts can be broadly classified under:

• Energy use ( extraction processes of raw pigments, pigment dispersion and let-down processes during manufacturing)

• VOC emissions ( leads to global warming and environmental pollution )

• Environmental safety and human health (heavy metals and toxic pigments) With new developments in infrared reflective pigments and thermal insulation materials, energy saving paints or thermal insulation coatings that resulting in energy conservation and reduction of air conditioning costs are increasingly being applied on walls and facade. The development of the criteria includes the research and study on existing green labels of various countries under the Global Eco-labelling network. Hence, relevant criteria were studied and extracted to derive a set of evaluation criteria to minimize the pollutant impact on the indoor air, conserving resources and reducing energy and water consumption.

2. SCOPE The criteria shall apply to decorative and energy-saving, liquid-applied and air-dried wall paints, external façade coatings and solar reflective or energy saving paints. The


technology or principles for the paint performance include photocatalytic mechanisms, self-cleansing products from either hydrophobic or hydrophilic properties or simple air dry systems.

Clear finishes and specialty (industrial, marine or automotive) paints and coatings or those sold in aerosol cans are not included in this document.

3. DEFINITIONS

“Aromatic Solvent” means any organic solvent that has a benzene ring in its molecular structure “Component” means an intermediate product used in the manufacture of paint or coating “Halogenated solvent” means any volatile organic compound incorporating halogens including fluorine, chlorine, bromine and iodine. “Integral part” means a necessary component that is intentionally added in the paint formulation “Paint” means a pigmented liquid that is designed for application in single or multiple layers and forms and opaque, continuous film after application to decorate or protect the surface or conceal surface irregularities. “Coating” means a pigmented resin that are converted to a solid adherent film after application to a substrate as a thin layer and is used for decorating, protecting, identifying or to serve some function purpose as filling or concealing of surface irregularities or the modification of light and heat radiation characteristics. “Volatile Organic Compound” means any organic compound which has a vapour pressure more than 0.1 mmHg at 25°C. This definition excludes reactive diluents, which are designed to be chemically bound into the cured film. “Energy Management Programme” means a program to achieve and sustain efficient and effective use of energy including policies, practices, planning activities, responsibilities and resources that affect the organisation’s performance for achieving the objectives and targets of the Energy Policy.
