Deployment of renewable energy in the province of Punjab – Drivers and barriers

Muhammad Ummad Arif and Ayesha Athar

In this paper, drivers and barriers associated with deployment of solar, wind and hydro green energy generation in Pakistan’s second largest province Punjab have been explored. Through extensive analysis, it is established that foreign investments in local projects, advancement in renewable energy (RE) technologies such as energy storage systems, reduction in carbon emissions, provision of net-metering, and significant cost and energy savings are key factors in driving the use of renewable energy systems in the region. On the other hand, barriers towards the deployment of renewable energy generation are equipment theft, lack of trained personnel, site conservation issues, lack of long term policy, high transaction costs, financial and institutional barriers and power sector transmission losses. In order to overcome these barriers, substantial action is being taken by the Government of Punjab in the form of training programs, revised legislation, monitoring of installed renewable energy projects and proposing more efficient models of renewable energy generation.

Keywords: Renewable energy; drivers; barriers; policy.

Vegetation and Cool Materials on Building Envelopes: Impacts on Indoor Temperature and Energy Use in Indonesian Tropical Residential Buildings

Salsabila Adela Putri

‘Green’ and ‘cool’ building envelopes, which integrate vegetation and reflective materials on the roof and external walls, are recognised as effective solutions to mitigate overheating on the building and city scale. This study aims to assess the impact of these adaptations on residential buildings in the equatorial zone of East Kalimantan, Indonesia, which is characterised by high temperature and solar radiation year-round. Using DesignBuilder, this study compares green and cool strategies for roofs and walls across different building archetypes. Although the magnitude was low, results indicate that roof adaptations generally outperform wall adaptations in reducing indoor temperatures and cooling energy use. Among adaptations assessed, cool roofs exhibited the highest cooling potential. Differences in roofing systems influence the resulting daily cooling patterns. However, as the complexities increase, the cooling benefit of all adaptations becomes less pronounced. This research underscores the importance of sustainable building design in addressing climate change challenges in Indonesia.

Climate change mitigation and adaptation of UK complex-to-decarbonise homes: building fabric vs. systems upgrade approaches

Maimai Prayongrat

Buildings account for 31% of the global final energy demand, 70% from residential sector. Complex-to-decarbonise dwellings emit 25% of the residential sector’s CO2 emissions. While decarbonising can be challenging, effective retrofit solutions are required to reduce energy consumption and overheating risks. This paper identifies solutions and challenges to retrofit complex-to-decarbonise homes, focusing on two case studies: a pre-1919 Victorian mid-terrace house in Battersea, London, and a 1966 social housing high-rise flat in Southsea, Portsmouth. IES VE simulation assessed the impact of different retrofit packages in current and future (UKCP09) climate conditions, including heating system upgrades, passive heating and cooling strategies, and their combination. Results show that combining passive measures with electric heat pumps provides optimal outcomes, reducing energy consumption by 74.2% and 75.6% in the house and flat, respectively, while mitigating overheating. Additional measures are necessary to achieve net-zero and TM59 targets in the future, considering technical and financial feasibility.

Keywords: Complex-to-decarbonise homes; building retrofit; climate change; building energy consumption; overheating risks.

Cooling Architecture: Prototyping an Optimised PDEC-integrated Façade Panel to Enhance Urban Thermal Comfort

Elisa Martini

Integrating passive downdraft evaporative cooling (PDEC) into facades offers an innovative method of decreasing surface temperatures and creating downdraft currents that help cool buildings and their surroundings. Analysis of available literature revealed a significant lack of understanding in the effects PDEC-generated downdraft on internal and external environments. This paper is a summary of a dissertation aiming to design an effective PDEC-façade panel and evaluating its cooling potential and effect on surrounding microclimates. Prototype testing in the evaporative cooling (wet) experiment resulted in surface temperature 11 C lower than the control (dry) experiment. The prototype produced an equivalent cooling energy of 2800Wh. These results show a clear cooling benefit of the panel, demonstrating its potential use in new builds or retrofit construction projects, helping reduce cooling loads and improve comfort conditions around the building.
