This work aims to reduce the energy consumption of existing buildings through retrofitting and converting them into net zero (NZEBs). Various retrofits for an academic building were modeled analyzed using REVIT software. Energy was reduced approximately 34% retrofits, a Solar System 41.6 kW integrated meet demand, consequently (NZEB). Furthermore, environmental economic analyses conducted, resu...

in some climates, massive buildings made of stone, masonry, concrete, earth and … can be utilized as one of the simplest and most effective ways of reducing building heating and cooling loads. very often such savings could be achieved in the design stage of the building and with a relatively low-cost. such declines in building envelope heat losses combined with optimized material configuration ...

Decarbonizing the building sector is extremely important to mitigating climate change as contributes 40% of overall energy consumption and 36% total greenhouse gas emissions in world. Net-zero buildings are one promising decarbonization attempts due their potential decreasing use increasing share renewable energy. To achieve a net-zero building, it necessary decrease demand by applying efficien...

Several advanced economies are in the process of a transition towards zero emission housing by 2020. Such transitions require a radical shift beyond existing limited building envelope and energy efficiency improvements. The Zero Emission Housing (ZEH) concept indicates such a radical shift, implying as it does home energy consumption within limits set by the home itself, and renewable energy te...

Recent years have seen an increasing public interest in issues related to energy saving and environmental pollution reduction in the building sector. As a result, many directives have been issued, the most important being the Directive 2010/31/EU (EPBD Recast) on the energy performance of buildings, which requires that “Member States shall ensure that by 31 December 2020 all new buildings are n...

In this paper, based on maximizing the outrigger-belt truss system’s strain energy, a methodology for determining the optimum location of a flexible outrigger system is presented. Tall building structures with combined systems of framed tube, shear core, belt truss and outrigger system are modeled using continuum approach. In this approach, the framed tube sys...

Tall building structures with combined systems of framed tube, shear core and outrigger-belt truss system’s are modeled using continuum approach. In this approach, the framed tube system is modeled as a cantilevere...

There are many different possible combinations of building envelope, utility equipments and onsite energy generation equipments that can lead to net zero-energy performance. For instance, a building with standard design can offset its energy demand by adding a large amount of photovoltaic cells or by improving its energy efficiency rating first and then adding a smaller amount of photovoltaic c...
