Bengal TigerTigers are the largest members of the cat family and are renowned for their power and strength.Over the last 100 years, hunting and forest destruction have reduced tiger populations from hundreds of thousands of animals to perhaps fewer than 2,500.Tigers are hunted as trophies, and also for body parts that are used in traditional Chinese medicine.Did you know?A tiger's roar can be heard as far as 3 km awayLocation: India, Bangladesh, Nepal, BhutanAn Economic-Managerial Approach.

Location: Zirmunu str. 116, Vilnius build in 1968 complex of 8 multistory buildings concrete prefabricated apartment bloc- 5 story building, accommodate 30 flats has no former refurbishments 468 m2 ground floor- 1600 m2 surface of external walls- 430 m2 surface roof- no insulation bad U-values good S-W orientation

AnalyseSustainable design & construction

Ways WE can minimize the CO2 emissions: Highly insulate external wallsBetter insulation of the roof (&green roof)Windows replaced with triple glazing onesInsulation of ground floor slabEliminate air leakagesHeating system upgradedUse renewable energy (rainwater collector)Each apartment is provided with area for growing vegetables

VENTILATED FAADE SYSTEMSustainable design & constructionConcept less is more Less raw material - less energy - less waste

Thin as glass, light as a shell, durable as stone, strong as concrete, universal as wood

Combines cement, water cellulose, textile fibers and airLighter, thinner and stronger materials

Sustainable design & constructionAdvantages:

-lighter, thiner and stronger -low energy production process -high performance composite -excelent fire protection-frost proof-resistant to fungi and insects-minimal or no maintenance-resisting moisture and humidity-prevent internal condensation- UV coating can offer good protection against graffiti- remove 100% of the fibre cement waste- reduces the carbon footprint of fibre cement products- long life cycle that can resist up to 60 years

Disadvantages: -not 100% recyclable-can be hard to make changes to the boards on site because it is easily damaged

Sustainable design & construction

Sustainable design & construction- Wall to panel construction- A subconstruction is needed - Between the vertical profiles is space for insulation- The insulation is securely fixed to the structure with special fastenings-To help eliminate the bridge from metal to the structure, plastic wall brackets are installed- The cavity permit air movement and water drainage- Always leave 20 mm gap for thermal movement of aluminum

-bigger kitchen connected with the day zone

-open living room

-modernized bathrooms

-posibility to open the balcony and bring the exterior inside

-larger balconyGrowing vegetables place

Sustainable design & constructionBalconies - improve health with fresh vegetables - save money on groceries- reduce environmental impact - enjoy bettter-tasting food- no worries about food safety- reduce food wasteAGENDAWHY this topic ?High diffusion of Refurbishment actionsClients demand about reduction and sustainable energyMajor attention to ecological buildings 2.

WEAKNESSESAbsence of Important Skills:Poor competence of enterprises in charge to apply new technologies on GR and FAs the instalment and the assembly has to be applied by local and Small Enterprises this reduce the competencies available for good performancesWeak BrandsPoor access to distributionLow customer retentionUnreliable product/serviceBad orientation and poor exposition of facades and roofs for insulation

Sub scale The dissemination of the buildings refurbishment owing to the in progress crisis didnt reach a minimum scale to reduce costsManagement High costs of installationHigh Maintenance costs increasing with the ageing of roofs and facadesGreen roof/Facades design

THREATSChange customer baseThe small property of buildings diminishes owing to the economic crisis and the big owners didnt perceive ecological investments as convenientTechnological advances Scientific researches demonstrated that Green Roofs and Facades didnt fulfil expected results in ecological fieldChanges in Governmental PoliticsOwing to a worsening of economic crisis the government ends or cancel facilitations for ecological interventions on buildings Tax IncreasesIncrease of taxes on the properties owing to the increase of building value consequent to the appliance of Green Roofs and Facades considered a luxury indexChange in population ageNew Distribution ChannelsManagementDiffusion of new plant disease that destroys the plantsNeeds of expensive products to treat plants against new type of diseaseGreen roof/Facades designConclusions

Financial IncentivesGreen roof/Facades designThe green space environment including natural and urban green space are indispensable to human life and its existence. It can be regarded as an ecosystem connection between components and the green space environment, soil, water, vegetation, weather and topography, which are essential for the development and conservation studies of green space.Human environmentLandscape/Urban planning

Water collector tank - Rainwater Harvesting Systems

Rainwater harvesting is simply collecting rain which falls on the roof, then storing it and using it as a free resource.

Advantages : Saves money by reducing water usage.

A volume of water is kept out of the storm-water management system there by helping to reduce flooding risks.

Rainwater is better for the garden as it has a balanced ph and is free of chemicals such as chlorine.

The greenhouse simulates a warm, spring- to summer-like environment that protects plants from hot or cold shifts in temperature.

We can control everything about plants, including the temperature, shade, and watering.
