The Impact

With the rise in awareness of energy efficient buildings and adoption of mandatory energy conservation codes across the globe, significant change is being observed in the way the buildings are designed. With the launch of Energy Conservation Building Code (ECBC) in India, climate responsive designs and passive cooling techniques are being explored increasingly in building designs. Of all the building envelope components, roof surface has been identified as the most significant with respect to the heat gain due to the incident solar radiation on buildings, especially in tropical climatic conditions. Since ECBC specifies stringent U-Values for roof assembly, use of insulating materials is becoming popular. Along with insulation, the shading of the roof is also observed to be an important strategy for improving thermal performance of the building, especially in Warm and humid climatic conditions. This study intends to assess the impact of roof shading on building’s energy performance in comparison to that of exposed roof with insulation. A typical office building with specific geometry and schedules has been identified as base case model for this study. This building is simulated using energy modelling software ‘Design Builder’ with base case parameters as prescribed in ECBC. Further, the same building has been simulated parametrically adjusting the amount of roof insulation and roof shading simultaneously. The overall energy consumption and the envelope performance of the top floor are extracted for analysis. The results indicate that the roof shading is an effective passive cooling strategy for both naturally ventilated and air conditioned buildings in Warm and humid climates of India. It is also observed that a fully shaded roof outperforms the insulated roof as per ECBC prescription. Provision of shading over roof reduces the annual energy consumption of building in case of both insulated and uninsulated roofs. However, the impact is higher for uninsulated roofs (U-Value of 3.933 W/m2K), being 4.18% as compared to 0.59% for insulated roofs (U-Value of 0.33 W/m2K).While the general assumption is that roof insulation helps in reducing the energy consumption in tropical buildings, it is observed to be the other way when insulation is provided with roof shading. It is due to restricted heat loss during night.

Indoor Air Flow

The energy consumption of AC (air conditioning) systems in large buildings is normally higher than the energy consumption in smaller buildings, and its indoor air flow field is also more complex than that in small building. To study the air flow mode and the indoor air flow fields in large spaces is of great significance to the energy conservation of AC systems and thermal comfort of the occupants. This paper presents an example using a large building that uses stratified air conditioning delivered through the linear slot sidewall diffusers and perforated sidewall diffusers. Using CFD simulation methods, three air flow field situations were simulated: (1) total air volume supplied from linear slot diffusers located in the middle of a side wall, (2) 50% flow through the linear slot diffusers the remainder supplied through the perforated sidewall diffusers, (3) 30% of the volume supplied with linear slot diffusers, 70% supplied through the perforated sidewall diffusers. The simulated results show that the third airflow mode is the optimal one for the three modes, which is good for achieving energy conservation and a comfortable building thermal environment in buildings with large spacial areas.

The Queen’s Residence Energy Challenge (QREC) is an energy conservation initiative taking place in the residence halls at Queen’s University coordinated by the AMS Sustainability Office and the Sustainability Coordinator for Student Affairs . It is a two-part competition. Part one of the competition is an interresidence competition in which each residence hall will be competing to reduce their energy expenditures. Energy use will be compared to the corresponding time in the previous year, and the residence that reduces their energy use by the highest percentage will win the competition. This part of the project is being organized by members of the AMS Sustainability Office and the Sustainability Coordinator (Office of Student Affairs), and Residence Life staff and floor dons are helping execute it. The second part of the competition is an inter-university pledge drive, in which residents will be encouraged to sign a pledge stating that they will be participating in the QREC. Queen’s will be competing against the Universities of Waterloo and Guelph, and the school that has the highest percentage of residents participating will win a set of solar panels as a symbol of energy conservation and renewable energy. This part of the project is being coordinated by the Sierra Youth Coalition who has obtained funding from the Ontario Power Authority. The goals of the QREC are to reduce overall energy use in the residences, help students living in residence learn about their own energy consumption and ways to reduce it, and create a culture of sustainability at Queen’s. In this presentation I will go through the overall timeline of executing and planning the project, provide examples of ways to reduce energy consumption in residence, and provide results of both parts of the competition.

Energy Conservation Measures

Precision farming is one of the important areas to ensure food security by coping with climate change and increase farmer’s productivity. Plant factory is one of the aspects of precision farming and recently sought attention among modern farmers in Malaysia. While ensuring continuous supply of crops throughout the year with increased quality and yield, plant factories consume large amount of energy to maintain their micro-climatic condition. This paper presents the energy consumption profiling of a plant factory, owned by Malaysian Agricultural Research and Development Institute (MARDI) in Serdang, Malaysia. This study is important to establish the status quo of consumption pattern of the plant factory towards reducing the energy consumption. Hence, energy audit was carried at the plant factory for duration of 2 weeks. From the audit it was found that the energy was distributed as follows: Air conditioning system - 51%, LED - 36%, pump - 3% and others - 10%. Finally, suitable energy conservation measures were proposed to reduce the energy intensity of the plant factory.
