  1. CRITERIA FOR GREEN BUILDINGS IN LEBANON Prepared by: The “Order of Engineers & Architects of Beirut” in collaboration with: Maya Karkour, Sara Jaber, Aram Yeretzian, Bassam Haber, Ziad Haddad & Wissam Tawil

  2. Table of Contents • Introduction • Green Building Criteria • Energy • Water Use Efficiency • Indoor Environmental Quality • Environmental Impact

  3. A- Introduction • Reasons to prepare the criteria • Scope of the criteria - Building Types - Climatic Zones Four Climatic Zones as defined in the Thermal Standard for Buildings in Lebanon - 2005

  4. B. Green Building Criteria Water Use Efficiency Energy Indoor Environmental Quality Environmental Impact

  5. 1. Energy Follow TSBL 2005 as issued by Ministry of Public Works & Transportation for insulation of walls, roofs, floors & glazed elements • Building Envelope • Energy Efficiency Minimum energy efficiency of DX, chiller or boilers to follow Ashrae 90.1 – 2007 Electric Hot Water Heaters to follow RT 2005 – art 58 • Elevators & Escalators Elevators: Building with more than 4 floors, use VVVF technology Escalators: Use on demand or reduce speed

  6. Artificial Lighting Lighting Power Densities for building (Interior) Lighting Power Densities for building (Exterior)

  7. Occupancy / Motion Sensor Electronic Ballasts • High frequency electronic ballast for fluorescent & Metal Halides conforming to IEC 60598 • Common lobbies • Parking • Circulation • Stairs • Keeping a max of 25 % of the normal lighting • Control System • Heat Recovery • Independent temperature control for A/C per zone. • Hotel room management • Thermostatic valve for radiators • Outside compensation recommended • 100 % FA AHU’s with heat recovery system. • Heat recovery on generators for hotels, hospitals, industrial facilities of certain areas.

  8. Insulation on Pipes & Duct • Energy Metering • As per Ashrae Standards 90.1.2007 for ducts & pipes • Electric metering for building with multiple Tenant. • Energy meters for building supplied with central chilled water or heating system. • Renewable Energy • In single family houses, Solar Panels to cover a min 70% of yearly hot water demand. • Residential building up to 4 stories, Solar Panels to cover min 30 % of yearly hot water demand. • In case of excessive external lighting above the allowable rate in Residential Building, PV panels shall be used to cover this excess.

  9. 2. Water Use EfficiencyA. Building Water Use Reduction • Efficient Sanitary Fixtures • Condensate Drain Recovery • Building with more than 200 tons, 80 % of condensate to be recuperated for irrigation, toilet flushing or cooling towers in zones 1 & 2 • Automatic shut off for public faucets

  10. B. Site Water Use Reduction • Efficient Irrigation • Rain Water Harvesting • Controllers with moisture sensors. • Drip or subsoil water delivery system. • Obligatory all single family houses, and collected from at least 25 % of roofs & external terraces. • Used for irrigation, toilet flushing, or general cleaning.

  11. 3. Indoor Environmental Quality • Natural Ventilation • Mechanical Ventilation • Openable area is 4 % of the internal floor area. • Opposite sides if between 7 & 15 m depth. • Follow Ashrae 62.1.2007 for occupied areas. • Follow decree 7964 for parkings.

  12. VOC Emissions – Paints & Coatings • Thermal Comfort 95 % of the year • Low Volatile Organic Compound for min 80 % of the paints internal surface. • Comply with: Green Seal GS-11 EN 13300:2001 EU Directive 2004/42/CE21

  13. Daylighting • Acoustic Performance • Comply with Lebanese Construction Law • Comply with Lebanese Official Gazette 1269/1996

  14. 4. Environmental Impact4.1 Impact of Construction Works • Dust Control • Erosion & Sedimentation Protection • Top soil shall be covered by sheets to prevent air pollution • Silt fences to be installed around the site to prevent annoyance to neighboring properties and land.

  15. Protection of Ecological Features Noise Control • Trees, hedges, ponds, water sources, wet land, not within building foot print shall be protected • Operate during the hours permitted by the applicable local regulations. • Construction Pollution • Construction Waste Management • Dumping of excavated soil or construction waste onto adjacent sites is prohibited. • Mandatory for Grade A project as defined in Decree 7964

  16. 4.2 Landscape • Vegetated Walls • Vegetated Roofs • Planters • 25 % of landscape area shall be vegetated. • In case of no landscape area, then 10 % of site area shall be vegetated on roofs, walls or planters.

  17. 4.3 Heat Island Effect • All buildings should have another 25 % either: - vegetated - Covered with high SRI material - Shaded by SRI material - Shaded by solar panels - Or a combination of the above • Roofs shall have 50 % of the non tech area: • Vegetated • Covered with high SRI • Shaded with high SRI • Shaded by solar panels • Or a combination of the above SRI: Index combining reflectivity & emissivity.

  18. Night Time Light Pollution • Operational Waste • Min 2 containers or bins for recyclable waste • Downward lights are required • Refrigerant Impact • Zero Ozone depleting potential (ODP)

  19. Conclusion: • A good start for implementing Green Philosophy in the construction law. • Neutralize the impact of the increase in exploitation rate. • Enhance the indoor quality environment. • Enhance the construction quality. • Reduce the energy and water consumption.
