English Abstract

Over last decades, maximizing the energy savings in the existing buildings was a challengeable issue that enabled the engineers to achieve the sustainability principles.

These principles depend on using less fossil fuel for meeting the heating and cooling demands of the buildings.

Net zero energy is a term of achieving high-energy performance that should be covered on-site generation by renewable sources.

The buildings should be able to reduce their energy demands through their envelope components.

Although sustainability principles are poorly applied on Gaza buildings, there is a hope to fulfill the high-energy performance through their envelopes.

This represents a guide for architects to produce energy efficient buildings in the presence of shortage in the electricity sector, especially that, there is only one supplier plant to Gaza areas.

Therefore, these buildings can cut down greenhouse gas emissions.

In this context, the stock of the existing buildings in Gaza could not be ignored as there is a chance to improve their thermal performance.

So, this study aims to identify the Net Zero energy retrofit strategies that could be applied to the building envelopes in Gaza.

In order to achieve this aim and the objectives of the study, the study based on the descriptive analytical method.

An experimental approach is conducted by using DesignBuilder V5 simulation tool that applies many scenarios that can be applied to achieve NZE principles to improve the thermal performance of existing multi-storey residential buildings in Gaza.

The outcomes showed that low thermal transmittance for the envelope components, and low shading coefficient for fenestration systems with mixed mode ventilation could get low energy consumption buildings.

The combination of double skin facade and vertical greenery systems (GDSF) was an effective strategy for ventilation whether as a passive or active due to its ability to improve indoor air quality.

Also, about 80% of energy savings was achieved.

The building produced an energy as a surplus that should be weighted and credited.

The cost-optimal solution achieved by less net site energy.

If pay pack were 11 years, the cost will be 1436 GBP in a month.

The study recommendations are as strategies that may benefit decision makers, architects and owners in Gaza to get NZEBs.
