Zero Energy Buildings: Design And Conceptual Analysis Of Waste House Building

Features of Zero Energy Buildings

Question:

Discuss About The Sustainable Food Production And Environment?

Zero energy buildings have the capacity of providing indoor comfort without the use of much energy. Since the Design and construction of the building are cost-effective towards decreasing the rate of energy consumption, it greatly helps conserve the ecology for the future generation. In order to minimize the rate of emissions of carbon dioxide and safeguard the environment, human beings are thus obliged to utilize a small amount of heat mostly in heating. Annually, it is estimated that the old structures are utilizing between  200 to 400 kWh/m2 amount of energy for heating purposes. The hope of future generation buildings energy consumption estimated between 20-50 kWh/m² (Buch, 2016)^.

Zero energy buildings will help to realize these as per the standards stipulated in its mandate. These structures utilize 90 % of the resources from households and wastes from construction sites that are used to build the waste house. Examples of the discarded materials are toothbrushes, DVD cases, floppy discs and carpet tiles. The research paper is centred on the analysis of the design of a waste house in Brighton's University which is carbon free and zero energy building. Besides, the report focuses on the conceptual and detailed design of the building. (British, 2015).

Zero energy buildings are buildings which are regular and poses some desired features such as being well protected, airtight and energy efficient. They provide a house which is carbon free and has an overall zero energy. For instance, their design is a bit advanced from the old buildings i.e. incorporation of double-walled houses they are purely solar panelled thereby making them a zero free energy structure. They promote sustainability, affordability and also they increase the human comfort. Besides, they are of high quality since they are more durable as compared to others.  Below are some terms used in the construction o a waste house building (Frank, 2017).

• Zero net site energy use – this refers to the amount of energy that is utilized by the building and it is availed on the site by renewable sources of energy.
• Zero net source energy use: this refers to the utilization of the total amount of energy that is produced by the renewable sources of energy.
• Net zero energy emissions: this refers to the balancing of the carbon emissions that are produced off-site with the carbon-free energy that is produced by the renewable sources.
• Net off-site zero energy use: this refers to the utilization of energy which is carbon free and generated by renewable sources of energy off-site.
• Net-zero energy building: this refers to an energy efficient building which is connected to the grid and it allows for the production of energy from the renewable sources to restitute the energy requirement.

The preliminary design for the conceptual design phase of the Brighton waste house project entails the definition of the various configurations and provision the layout of the project in terms of various schematic diagrams .there are some basic requirements that will be of great significance in consideration of the conceptual design. These include the

• Reduction of house's energy requirements: Insulation will assist in minimizing the amount of heat lost and gained during the winter and summer season respectively. It also avails building envelopes including slab, roof and walls. A barrier constituting air will minimize the heat loss and heat gain (Heinz, 2016).
• Production of clean energy required: this entails the production of energy from renewable sources of energy such as solar that are more sustainable.
• Efficient operating the house: this entails the use of appropriate appliances and operating temperature conditions.

 The waste house project will need some of the elements in various systems such as;

On the heating and the cooling system of the house, a geothermal heat pump will be required since when it is connected to a de-superheater, it will be able to heat and cool thereby supplying both cold and warm water into the house. Besides, it will be operated under maximum utilization of earth temperature. This temperature allows interchange of heat medium with the external air temperature and consequently increasing the efficiency of the system (Goncalves, 2016).

Design and Construction of Waste House Building

For the water heating system, solar thermal modules will be very appropriate. This is because they greatly help in saving costs that could be used when electricity was otherwise generated. There will be constant water recirculation system that provides for both the hot and cold water. The hot water can be supplied to the kitchen as well as the bathrooms (Graham, 2015). 

The lighting system of the house will basically involve electricity generation through solar panels.  This will greatly help in reducing the energy costs as once the installation is done, then there will only be the need of installing temporary power storage devices such as batteries to supply electricity during cold seasons and at night (Heinz, 2016).

The ventilation system will be mechanically enabled and will be energy efficient to help in the quality of fresh air. It will be an Energy Recovery Ventilation system which balances the humidity. 

This section elaborates each aspect of the waste house by providing some specifications and costs. There are some tools that will be required that will be used in the design o the waste house. These tools include

The design of the zero house building entails the use of various models during its design process. Generally, there are various models that are applied during an engineering process design. This includes v- model and waterfall model. However, the model that was applied in the design of this building is the v-model which ensures that at each and every stage, there is a test to ensure performance and efficiency which is always contrary to the waterfall model. The waterfall model makes it difficult to rectify most issues as it is applicable at the end of the design process. Hence, below are some of the various v model design techniques that were applied (Maldonado, 2016). 

Design performance modelling which is established to estimate the performance of the house with regards to the ventilation, daylight penetration, energy efficiency, and the thermal comfort

Building energy modelling: this is modelling tool that comprises of data and information which gives predictions and assumptions on the performance and maintenance of the waste house.

Building operation modelling: this is a modelling tool that allows for the calibration of the building energy modelling and is basically used in the monitoring of the building. It permits for calibration of building energy modelling (Moubray, 2015)

Project resource modelling this is a modelling tool that assesses the difficulties that will have effects on the project development of the project. Besides, hi stool demonstrates the correlation between efficiency, conservation and consumption.

Fundamental Elements of the Waste House Building

Besides, there are some fundamental elements that need to be incorporated into the system. These include.

The validation n process focuses on the analysis technique whereby testing is executed by implementing the code. Besides, a detailed specification is provided as shown below on the:

The fundamental demands of the structural elements of the waste house can be given as:

The cost of energy consumption and production is estimated by the use of a computer modelling device. A software is known as a zero energy residence optimization aid in the designing part of the waste house by incorporating ways of minimizing the energy consumption rate and the cooling efficiency as well.  The specification of the waste house includes a heating system, insulation level, electrical layout, lighting system and the various domestic appliances. Besides the main source of energy used is a solar power which essentially minimizes the cost of energy to zero. A complex 3-dimensional simulation tool is used to determine the performance of the building under various conditions such as the local climate, insulation type, heating efficiency, among other variables (Zeiher, 2016).

This process refers to the way of obtaining a substitute but with the most cost-effective or maximum realizable performance under the given constrictions, by exploiting desired factors and minimizing undesired ones. This has been in the project by the application of the above modelling techniques which reduces the amount of energy consumption. For instance
