Articlefield with 30.000 employees into a new organizedfield where job security, healthy work environment,efficient production, environmental awarenessand energy-effectiveness are available. Under thisplanning, gas emissions of existing buildings,chemicals used by these buildings, their productionvolumes, liquid wastes, metal losses, environmentalimpacts and water, gas, electricity, heating andcooling consumption rates were measured under themanagement of Istanbul Technical University’s (İTÜ)Department of Environmental Engineering. Then thesemeasurements were evaluated. It has been agreed tomake the new building in compliance with traditionalproduction method. Additionally, it has been aimed tomake mechanical solutions enable the improvementof business.Results of Measurement• Damage of acidic-basic wastewaters to generalsewerage system, being out of condition in patchesand interference with ground waters and seawaters.• Environmental limit values of gas emissions arehigher than 200% in some cases.• Damage to the historical buildings.By considering these values, liquid wastes werecollected from each enterprise with 5 different lines.Then they were connected to the following areas:1. Acidic waters – to the balancing pond of treatmentunitResults of Liquid Wastes MeasurementProduction UnitsType of WastewaterAmount(l/kg ProcessedGold)Amount(m/day)34 * Basic wastewaters originating from flue gas washing systems.TTMD 2013
Article2. Basic and cyanide water – to separate balancingpond3. Gypseous and detergent waters – to the lifting pond4. Hand-washing and shower waters – to the mainsafter recovery5. Domestic wastewaters – directly to the mainsWith this method, precious metals (gold, silver, etc.)in melt state in chemical waters and in powder statein cleaning waters have been recovered at 80%. Bymeans of continuous controls, liquid wastes underthe limit values of mains system were released to theinfrastructure.Results of Gas Wastes MeasurementTABLE 1.

Emission Measurement Results of HydrochloricAcid (HCI) ProcessingFeatures of Fume Hood Stack Emission Measurements Exhaust SystemGas emissions at the workshops determine theventilation system. As an example to this statement,features of wax melting furnace stack, emission valuesof fume hood stack and measurement results of fumecupboard stack are given in Table 1, Table 2, Table 3 andTable 4. Since it has been not possible to determine thefinal production conditions of workshops, a diversityfactor was used again and a vertical channel line wasestablished for each exhaust. Vertical lines carry overexhaust emission from fume hoods of acidic and basiclines in the workshop separately, furnace lines carryover exhaust emissions from furnaces and fume hoodsand ambience lines carry over the exhaust of generalatmosphere. Acidic, basic and furnace exhausts areclosed when they are not in use and therefore, theworkshops that are out of use or with no productionat that moment produce no emission. Exhaust fanson the roof provide significant energy saving asthey have frequency inverter. Also, when required,it prevents deviations in diversity factor. In order toensure chemical resistance in acidic and basic lines,CTP lines will be used and furnace lines will be madeof black sheet for temperature resistance. The fansinstalled on the roof of each vertical shaft will be madeof PVC. As a rule, treatment, filtration and washingoperations of gas emissions at the production unit ofeach workshop will be made at the absorption unit atthe end of each fume hood, they will be processed byusing NaOH in acids and water in basics and will beconnected to main lines. However, it is assumed thatfaults and failures may occur because of technicalreasons and users and therefore, exhaust airsextracted from these lines are released from the topend of penthouse. Also, necessary reservation areasare created for central secondary treatments in casethe values which will be checked through continuousmeasurements exceed environmental limit values. Inacidic and basic lines, condensations occur due totemperature differences and emission concentrations.These condensations are connected to the lines whereliquid wastes are collected, by placing drainage inletsunder the channels.Heating - Cooling - Ventilation - HvacAverage Conditions in Existing BuildingsBuilding Envelope:Window U-value 4.5 W/ m²KWall U-value1.5 W/ m²K35TTMD 2013
