Description and Benefits of Green Buildings Green Buildings are high performance structures that also
meet certain standards for reducing natural resource consumption
Green or sustainable buildings are characterized by efficient management of energy and water resources management of material resources and waste restoration and protection of environmental quality enhancement and protection of health and indoor
environmental quality reinforcement of natural systems analysis of the life cycle costs and benefits of materials and
methods integration of the design decision-making process
Design/Construction: Traditional ModelOwner contracts with the designer separately
who makes the DD and CD documents
After completing the design, owner contracts with the construction contractor
All the stakeholders work separately implementing consequent iterations
Design/Construction: IntegrativeModel Mandatory for Green BuildingsOwner contracts with designer, green
building consultants and construction company at the same time
All the stakeholder take part in decision making process from the very beginning of the design documents’ phase
In the result the designed and constructed building will have the highest possible performance
LEED Description
Leadership in Energy and Environmental Design (LEED)
Rating system established by US Green Building Council (USGBC)
Certification is carried and awarded by Green Building Certification Institute (GBCI)
Case of Avedisian High School Building in ArmeniaTo construct the first environmentally
responsive and certified building in ArmeniaTo gain LEED silver certification for the
schoolTo enhance the performance of pupil by
providing proper indoor environmental quality
To develop a new construction culture in RA

Prerequisites and CreditsOptimize Energy Performance
Building orientation Energy efficient building
design starts from correct orientation
South orientation provides the maximum solar gains during winter season
Prerequisites and creditsOptimize Energy Performance
Polyurethane insulation Financed by UNDP
Local Perlite Mineral wool
IndoorRoofThermal bridges
Prerequisites and creditsOptimize Energy Performance
Condensing boilers Absorption chiller
Prerequisites and CreditsOptimize Energy Performance
Consumes 8-10 times less than incandescent lampsConsumes 2-4 times less than fluorescent lampsLife time is 50,000 hoursNot hazardous to health & environment
LED lighting
Prerequisites and CreditsOptimize Energy PerformanceNatural lighting
95% of the spaces areprovided by naturallighting
Almost no energy isconsumed on lightingduring day time
Natural lighting increasesthe educational outcomes
Prerequisites and CreditsOptimize Energy PerformanceCool roofs and green roofs
Cool roofs reflect solar irradiation during summer season and reduce the cooling loadGreen roofs keep the roof cool in summer season because of water evaporation through the roots of the plants
Prerequisites and CreditsOn Site Renewable Energy
Cooling
Under floor heating
Water heating
First time in the world three in one combined solar water heating, solar space heating and solar cooling system has been designed and is being implemented
150kW solar panels are going to be installed
Solar thermal
Prerequisites and CreditsOn Site Renewable EnergySolar photovoltaic
10kW solar photovoltaicpanels are going to beinstalled at the site
These panels will beconnected to the electricitygrid of the building as thereare legislative issues withconnecting them to themunicipal grid
Prerequisites and creditsIndoor environmental quality (IEQ) Minimum IAQ performance Environmental tobacco smoke control Minimum acoustical performance Fresh air delivery monitoring IAQ management during construction IAQ management before occupancy Indoor chemical and pollutant source control Thermal comfort Daylight in the building Views Mold prevention
