1 The Influence of Green Building Concept to Fastening and Fire Protection Technology By Ir Michael Leung Marketing Manager Hilti (Hong Kong) Limited April Agenda Manufacturer related to Green Building Design Green in Passive Fire Protection Additional Attribute in Passive Fire Protection Green in Anchor Fastening Example projects 2

2 Green Building Design Not just a slogan Design & Material Selection Construction Maintenance & Renovation Green building design involves in all phases during the building life cycle 3 All environmental regulations / measures lead to the same goal ISO14001 Environmental Management System - released in by the International Organization for Standardization (ISO) - to decrease the pollution and waste a business produces EIA Environmental Impact Assessment (by EPD) CWMP Construction Waste Management Plan Sustainability in Building Construction 4

3 All environmental regulations / measures lead to the same goal HKBEAM Building Environmental Assessment Method Site (17%) Materials (18%) Energy (25%) Water (10%) IEQ (30%)* *with minimum requirement I&E (5%) - Bonus 5 What s LEED? The Leadership in Energy and Environmental Design - Green Building Rating System, third-party certification program. - Standards for environmentally sustainable construction Green building - Developed by the U.S. Green Building Council (USGBC) Each Area: Prerequisite(s) + Credit(s) 5 key areas Both LEED and HKBEAM are common green building standards in HK 6

4 Every single efforts count Government parties How to make the right choice in design & specification & construction Green Building Design Developers Architects Engineers Contractors Total System Solution Manufacturers Hilti is only an example to show how manufacturers can contribute to Green Building Design It s more about change in habit than methodology & most importantly NOT necessarily induces to increase in construction cost 7 Total System Solution Focus: Fire protection, Anchor fastening & associated Tools 8

5 Green in Passive Fire Protection 9 What is passive fire protection? 4 Levels of Life Safety Fire Compartment Walls & Floors FW FW Prevention FF FF FF FF FF FF Detection FW FW Weak Points in Buildings Active Fire Protection Passive Fire Protection 1 Unsealed / Open Joints 2 Unsealed Cable Penetrations 3 Unsealed Pipe Penetrations / Ducts 4 Doors / Windows 10

6 How does HILTI contribute to LEED credits? Sealant: Air Tightness Major Involvement HIT grout: Foil-pack HILTI contribution towards LEED credits up to 29 points 11 Emission reduction achieved by limiting air leakage High-end air-conditioning system BUT Continuously leaving the door/window open!! Electrical & Mechanical Internal Finish Curtain Wall Up to 1/3 of the benefit of employing highly energy-efficient cooling systems may be lost by NOT addressing air leakage in building design & construction 12

7 Worldwide standard to control air-tightness Great Britain Approved Document L Germany EnEV Energy Conservation Act Door and window joints Air leakage in new buildings must NOT exceed 10 m 3 / h outer surface area in m 2 13 Testing for air-tightness The pressure of the atmosphere in the whole building increased Time consuming and costly Full Scale Blower Door Test Tested gases: Methane main constituent of natural gas (flammable) Nitrogen & Carbon Dioxide main constituent of the air Tested pressure: 50 Pa & 200 Pa Laboratory Pressure Test 14

8 Air-tightness in relation to LEED Only by ensuring the air-tightness of the building, the cost effectiveness of any energy saving airconditioning system can be justified. EA Prerequisite 2: Minimum energy performance REQUIRED Intent: To establish the minimum level of energy efficiency for the proposed building and systems; to reduce environmental and economic impacts associated with excessive energy use. EA Credit 1: Optimize energy performance 1 19 points Intent: To achieve increasing levels of energy performance beyond the prerequisite standard to reduce environmental and economic impacts associated with excessive energy use. Air-tightness Test Report Leave the door open or not your choice! 15 Construction Waste Management in HK (1988 ~1996: 13 landfills were closed) Current situation: 3 Strategic Landfills Landfill Location Opened Capacity (million m3) Status West New Territories Landfill (WENT) Nim Wan, Tuen Mun Active South East New Territories Landfill (SENT) Tai Chik Sha, TKO Active North East New Territories Landfill (NENT) Ta Kwu Ling Active Finding in Extension for Existing Landfills and Identification of Potential New Waste Disposal Sites (2003): All existing landfill capacity would be exhausted around mid 2010s if waste disposal continues at the current trend. Planning for extension of the west of the existing WENT Landfill (Total estimated landfill capacity = 81Mm 3 ) What will be our next plan? Can we continue with this trend? 16

9 Construction waste is one of the main sources of solid waste disposed to landfill site Findings from interviews with several E&M contractors: 6 key solid wastes from their trade: 1. Cable drum 2. Cardboard packaging 3. Metal from pipe/cable/cable tray 4. PVC pipe 5. Pipe insulation 6. Sealant hard cartridge Annual consumption of firestop sealant alone can up to 5 million pieces. 17 Changing from hard cartridge to foil pack 90% of waste volume reduced during disposal 20ft container Volume saved in solid X 40 waste disposal (per year) = ~1,400m 3 = Construction waste reduction by using foil pack is significant! 18

10 Foil-pack in relation to LEED Other than recycle and reuse, reduce can also be an effective way in controlling construction solid waste disposal to landfill sites MR Crediit 2: Construction waste management 1-2 points Intent: To divert construction and demolition debris from disposal in landfills and incineration facilities. Redirect recyclable recovered resources back to manufacturing process and reusable materials to appropriate sites It s all about minor changing the current practice 19 VOC in relation to LEED Low levels of volatile organic compounds (VOC) is one of the key factors in providing maximum comfort for building occupants 1 point IEQ Credit 4.1: Low-emitting materials: adhesives & sealants Intent: To reduce the quantity of indoor air contaminants that are odorous, irritating and/or harmful to the comfort and wellbeing of installers and occupants VOC Test Report VOC limit: 250 g/l (architectural sealant) Testing method: EPA #24 It s not just about the VOC content the testing method is as equal important 20

11 Will they induce to increase in construction cost? Air-tightness of building joints Low VOC content Foil pack No! It s only a matter of modifying specification and asking for additional info. 21 Additional Attributes - Sound insulation - Water tightness 22

12 Multi-function as another way to save materials 23 Green in Anchor Fastening 24

13 Drilling holes as a first step for anchor fixing Anchor installation involves dust generation on site 25 Dust removal system for hole drilling Drilling TE DRS-M Dust removal module Other than drilling, breaking, grinding, slitting & sawing also involves dust generation 26

14 Dust removal system for other applications Grinding 27 Dust generation in relation to LEED Dust is produced by many of the processes carried out in the construction industry (drilling, slitting, breaking). REQUIRED SS Prerequisite 1: Construction activity pollution prevention Intent: To reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation. Dust as a source of air pollution It s not just about wearing a mask or not! 28

15 Construction waste management chemical grout Before use After use Foil pack (Hilti) 80% volume reduced Hard cartridge (others) No change! Solid waste volume can be significantly reduced by using foil pack 29 Foil-pack in relation to LEED Other than recycle and reuse, reduce can also be an effective way in controlling construction solid waste disposal to landfill sites MR Crediit 2: Construction waste management 1-2 points Intent: To divert construction and demolition debris from disposal in landfills and incineration facilities. Redirect recyclable recovered resources back to manufacturing process and reusable materials to appropriate sites It s all about getting the right products 30

16 VOC in relation to LEED Low levels of volatile organic compounds (VOC) is one of the key factors in providing maximum comfort for building occupants 1 point IEQ Credit 4.1: Low-emitting materials: adhesives & sealants Intent: To reduce the quantity of indoor air contaminants that are odorous, irritating and/or harmful to the comfort and wellbeing of installers and occupants VOC Test Report VOC limit: 70 g/l (multipurpose construction adhesives) Testing method: EPA #24 Air Pollution Control (Volatile Organic Compounds) (Amendment) Regulation 2009 also apply to chemical anchors 31 LEED Project Examples in Hong Kong 32
