“…Smart building strategy is also a widespread topic for improving the energy performance, environmental awareness, and occupant comfort in buildings [19][20][21][22][23]. Energy performance strategies and various HVAC systems were analyzed in our previous research [24,25]. The research evaluates the overall energy performance and operational costs of a 45,171 m2 gross floor area commercial office building of the modern Innovation Campus in Budapest, developed by Wing Ltd. [26] The whole design and the construction process of the building was aided and followed by dynamic simulation of the complex to optimize its performance and overall energy consumption.…”

Contemporary commercial building?s demonstrate performance from a sustainability and environmental perspective. Usually, an appropriate energy performance is achieved using efficient mechanical systems, however the operation method with smart control is significant in the overall energy consumption. The research follows a two-year design and construction process of a commercial building where the integration of smart technology was a mandatory requirement by the owner, alongside with the prerequisites of the LEED? green building certification. The goal was to design, build and optimize the performance of the new Innovation Campus commercial office building complex using smart building solutions. The research was performed with energy modeling and dynamic simulation until completion of the building, where the design and investment decisions were constantly evaluated. The new optimized building?s performance demonstrated 42% of annual energy reduction and 34% of cost reduction according to the ?ASHRAE 90.1 Appendix G? baseline Benchmark building.

Energy utilization from various sources such as geothermal heat energy and different mechanical systems were analysed in our previous researches [30,31]. Hungary has numerous examples of Green certified buildings [32], but an overall analysis of building performance metrics does not exist among Green certified and nearly zero energy buildings.…”

The construction sector as one of the highest carbon emitters in the World has an international initiative for Green House Gas reduction. Green building certifications demonstrate performance, efficiency and economy in the constuction sector. The motivation of the research was to investigate whether Green certified buildings which fulfill the minimum energy standards do demonstrate high energy performance compared to energy efficient buildings and renewable systems. The hypothesis was to investigate that renewable energy source application could contribute to higher performance, against a typical efficient HVAC system (usually applied in commercial buildings) and a building aiming for Green certification, concerning mandatory energy efficiency requirement. The research scope was to investigate and evaluate various HVAC solutions using triple-criteria evaluation method for decarbonization: energy performance, carbon footprint and operation cost to formulate systematic solutions in the design phase of projects for wide audience with preferable and applicable results.

“…The main objective of this study is to develop an innovative solution for the exploitation of excess low-temperature heat sources of hot water boilers, which are discharged with exhaust gases into the environment. The heat that would be produced with one or more cascaded high-temperature heat pumps [14,15], by exploiting low-temperature heat sources of hot water boilers, would be used for preheating the return water of the high-temperature heating system in industry or district heating systems.…”

The article presents an original and innovative technical solution for the exploitation of low-temperature excess heat from hot water boilers that use gas or liquid fuel for the needs of high-temperature heating in buildings or in industry. The primary fuel efficiency used for hot water boilers can be significantly increased by utilizing the excess low-temperature heat of flue gases that are discharged into the environment and thus also reduce CO2 emissions. Hot water systems usually operate at higher temperatures of the heating water, which is transported to the heat consumer via supply pipe, and the cooled heating water is returned to the hot water boiler via the return pipe. For the excess low-temperature heat exploitation of the flue gases from hot water boiler, it is necessary to install a condenser in the flue gas discharge pipe, where condensation of water vapour present in the flue gas heats water or a mixture of water and glycol. The heating water, which is cooled and returned from the heat consumer via the return pipe, is led to the condenser of the high-temperature heat pump, where it is preheated and then led to the hot water boiler, where it is heated to the final temperature. A computer simulation with the Aspen plus software package for the series or parallel connection of high-temperature heat pump to a hot water heating system and the economic analysis of the excess heat exploitation from the flue gases are also performed.
