Done on my own:• created conceptual designs of heat recovery in manufacturing plants• made calculations of heat loss and gain in buildings• implemented the CADvent software for use in my designs, by creating an Excel based software which corrects errors and makes output data more universal • created conceptual designs of HVAC solutions on early stages of building design• created building designs of HVAC, required by law to get building permit• created 3D execution designs of HVAC with hydraulic balance and detailed part listings• validated above designs also for buildings under protection of the conservator of monuments• created 3D execution revision drawings of ventilation, allowing the calculation of the difference in costs, resulting from changes during construction caused by different interior finishing or changes in building geometry• created building designs of heating and cooling sources (over 500 kW), required by Polish building law to get building permit• created execution designs of heating and cooling sources with hydraulic balance and detailed part listings, powered by heat network, natural gas, propane butane, heating oil, electric current and vacuum solar collectors• created building designs of anti-smoky systems in high buildings, required by Polish building law to get building permit• created building designs of anti-smoky systems in crowded buildings, based on CFD made by other entrepreneurs, required by Polish building law to get building permit• created execution designs of compressed air installation and machinery room• created execution designs of semi-solid fire-extinguishing system, required by Polish building law in special cases• participated in coordination of interbranch, also in long direct sessions• wrote technical description of made designs• contacted manufacturers for technical solutions implementation in developed designs• supervised execution of made designs on construction site, required by Polish building law
