BUILDABILITY & GREEN MARK



WHY DO WE HAVE GREEN MARK SYSTEM?

•The initiative to drive construction industry towards more environment-friendlybuildings.

• To promote sustainability in the built environment and raise environmentalawareness when developers and design team start project conceptualization anddesign, as well as during construction.



•LOTUS was developed specifically for the Vietnam climate, culture and building industry.

•The rating tool is composed of categories representing the biggest environmental issues.

VIETNAM GREEN BUILDING COUNCIL



WHAT IS THE BENEFITS OF GREEN MARK?

• Green Mark provides a meaningful differentiation of buildings in the real estate market.

• It is a benchmarking scheme which incorporates internationally recognized best practices in

environmental design and performance. This can have positive effect on corporate image, leasingand resale value of buildings.

• Benefits include:1. Facilitate reduction in water and energy bills,2. Reduce potential environmental impact,

3. Improve indoor environmental quality for a healthy and productive workplace,4. Provide clear direction for continual improvement.



SAMPLES OF BUILDINGS



PASSIVE DESIGN – BUILDING ORIENTATION



PASSIVE DESIGN – SUN SHADING

•Building’s aesthetic value while

allowing enough daylight to the

rooms.

•Low sun angles which areharder to shade.

•Light colours are better at

reflecting solar radiation.



PASSIVE DESIGN – DAY LIGHTING

•Not introduce too much solar heat gain into the space.

•Design a system that minimizescontrast ratios and integrate

natural and electric lighting.

•Use daylight sensors



PASSIVE DESIGN – NATURAL VENTILATION

•Open space and non – air conditioned area.

•Airflow and energy simulations,

using the wind andmeteorological data.

•Effects of surroundingobstructions such as blockspacing and arrangement.



PASSIVE DESIGN – LANDSCAPING AND ROOFTOP GARDENS

•Gardens and courtyards inter-spaced between buildings.

•Rooftop gardens & Water features.



PASSIVE DESIGN



RESOURCES TREATMENT – WATER EFFICIENCY & HARVESTING

•Collection of rain water for cleaning and irrigation and water features.

•Irrigation system using rain sensor and time.

•Tap improvement



RESOURCES TREATMENT – UNDERGROUND ENERGY



RESOURCES TREATMENT – SOLAR



ACTIVE DESIGN – AIR CONDITIONING SYSTEM

•District cooling system

•VSDs onchilled water pumps

•VAV system with VSDs on AHUs

•Intelligent Building Managementsystem

•Independent VRV

•Motion sensors



ACTIVE DESIGN – LIGHTING

•High frequency electronic ballast.

•Intelligent Building Management system

•Zoning lighting

•Photocells to control exterior lighting

GREEN MARK ASSESSMENT CRITERIA & APPLICATION

•Green building rating system – evaluate a building for its impact and performance.•Endorsed and supported by the National Environment Agency.

•To promote sustainable design, construction and operations practices in buildings.

•To promote energy savings, water savings, healthier indoor environments, and adaption of more extensive

greenery for developers and design teams.




1. Assessment process:•Pre – assessment briefing to the project team for understanding of requirements and certification levelsought.

•Actual assessment verify relevant reports and documentary evidences.

•Re-assess every 3 years to maintain the Green Mark status. New and existing buildings will be re-assessedunder existing building criteria.

2. The assessment identifies the specific energy efficient and environment-friendly features and practicesincorporated in the projects

3. Points are awarded for incorporating environment-friendly features. The total number of points indicateenvironmental friendliness of the building design and operation.

4. Rating: Green Mark Platinum, GoldPlus, Gold or Certified




5. Application process:• Submit application form to register.

• The Relevant Agencies assessment team will have a preliminary meeting with the project team or buildingmanagement team to brief on the criteria and request for relevant reports and documentary proofs tosubstantiate the subsequent submissions.

• The later actual assessment will include design and documentary reviews as well as site verification.

•Documentary evidences are to be submitted at the end of the assessment.

•Upon completion of the assessment, a letter of award showing the certification level of the projects will besent to the team.
