1.0 IntroductionThe retrofitting project was carried out for the building located in 115 Batman Street, West Melbourne. The existing building was inspected on the base of the scope of retrofits required for additional chances and the amount of cost required for the owner in adding new features to the buildings. It was assumed that some of the essential parameters for the building included energy consumption CITATION Fer15 l 1033 (Ferreira, Pinheiro, amp De Brito, 2015). This report would be based on the potential of building to undergo the process of retrofitting.
The report would be based on the analysis of building owner who is Robyn Pty Ltd. It was targeted that NABR 5.0 rating should be established from the refurbishing process. The cost of the project would include about ten million US dollars. Greenhouse saving would also be incorporated for the building. The first part of the report would include an initial investigation for the report. It would be followed by the baseline investigation for the budget required and maintenance activities for housekeeping and energy consumption CITATION Mar182 l 1033 (Marique amp Rossi, 2018). The retrofit potential of the building would be measured with the help of location. Addition of new facilities in the facility aims to prepare the building for the current energy demands of New South Wales. A brief cost analysis would be carried out for the retrofitting of 385 Bourke Street building.

3.0 Procedure 1-Baseline Assessment3.1 Current building conditionsThe current building located in 115 Batman Street, West Melbourne is a commercial idea site for retrofitting and refurbishing process. This is because of the features present for an upgrade and an ample amount of space present for new features as well as instalments CITATION Mar175 l 1033 (Marini amp Passoni, 2017).
Table SEQ Table ARABIC 1 Baseline Assessment
Building Performance Excellent Good Reasonable Awful
Excellent Good Good The target can be achieved Reasonable Baseline Area Awful 3.2 Current building occupant leasesThe current building occupant leases for the building is present under the office of Norman Disney. The owner of the building is a private company. The occupant leases are present in fewer numbers as the building has been recreated. The tenants are present in the form of officers managers as the car workshop supplier CITATION um19 l 1033 (uman, igart, amp Premrov, 2019).
3.3 Current building performance3.3.1 ElectricalBuilding energy consumption is low because direct sunlight impacts the light for the first and second floor. This reduces the consumption of electricity at a cheap cost of energy. It is expected that in retrofitting process energy consumption would tend to increase in the coming years owing to the permissible ways in Melbourne. This would be measured with the help of NABERS energy scale.
3.3.2 WaterThe water consumption of the building is low in the off-peak hours. The work time and daily schedule tend to raise the importance of building in order to have a sustainable water usage system.
3.3.3 Waste GenerationThe waste is generated from the use of cans and bottles. The building can be managed for efficient use of materials and recycling system.
3.3.4 WaterThe use of water is 15000 litres. Tanks are present in the building to store the water. Water from flushing and rain is also used for cleaning purposes.
4.0 Establish Target for RefurbishmentClient target for refurbishment to achieve minimum loss of energy, within the five to ten years of performance for the buildings. The rating should be five based on the NABERS energy system rating. The present limit of the building requires changes in the use of energy as well as design.
The targets can be achieved by reconstructing the faade to a prominent length. This would allow the building to receive more sunlight and decrease the expense of cooling CITATION Mic15 l 1033 (Miccoli amp Fontana, 2015).
Building shell would require insulation from strong cladding material. This would allow the building to become energy efficient and store a higher amount of water in the tanks. It would also increase the energy rating.
An opportunity is present for chilled beams to be installed on the first and second floor.
Solar panels can be used for heating water and producing energy for the building. It would be an efficient source of energy creation.
The strategy for achieving five-star energy would be based on limiting the energy use for the building.
Changing the input of energy and making officers more convenient for renewable energy. It is also required that waste material for the material should be recycled with the help of technology so that the owner gets the maximum profit on building refurbishing. Some of the constraints can arise in the refurbishing process. This would account the budget of the client as well as products which have a higher expense for logistics CITATION Ses16 l 1033 (Sesana amp Grecchi, 2016).
5.0 Review Maintenance and Energy Usage5.1 Issues related to Housekeeping and MaintenanceHousekeeping and maintenance are based on the customers and officers. Buildings lack some of the function and in order to maintain the building for the five-star energy-based process. It is also required to maintain the building for its interiors and correct the materials applied for the interiors walls as well as the ceiling.
5.2 Energy, Water efficiency and other forms of issuesThe biggest issues for the building are based on the logistics of material which are required for the interior decoration. Floor slabs are required to maintain heavy equipment. This would require transport from windows CITATION Ber185 l 1033 (Berg amp Fuglseth, 2018). It is also required that Aluminum windows should be maintained with proper material and replacement should be carried out at regular intervals.
6.0 Decision Refurbish or DemolishThe decision for Refurbishing and demolishing would be based on the present condition of the building and amount of addition required for the electrical energy as well as water usage process. The present investigation of the building shows that minor changes in the electrical setup are required to increase the energy rating to five points. One of the key elements of the file is based on the circulation of air. The building should have vent holes which can allow circulation of air through the entire structure.
The building also needs to have a security system and requirements of Australia should be followed for efficient buildings design and refurbishment.
6.1 Actions required for the existing buildingThe build would be refurbished using the New South Wales codes of efficient energy consumption. A contracting company would be invited for the retrofitting operations.
The building has open slots for the ceiling as well as HVAC system to be installed for the purpose of refurbishment process. It is also required that the floor of buildings should be updated with wood. Water channels should have pipes with larger diameters, and solar panels should be installed on building roofs to decrease the amount of energy loss. One of the important additions would be glaze materials used for reflection CITATION Edw19 l 1033 (Edwards, Lou, amp Bataw, 2019).
6.2 Cost AnalysisThe entire cost for the building refurbishment is ten million US dollars. This would include the transport and logistics expense born by the owners and the maintenance required for the HVAC as well as solar systems. The prices of products will also be compared with the areas of the budget. A budget can exceed the required amount, but the present landmark of ten million dollars is the figures which would cover the entire range of refurbishment process of the building.

HVAC system 100,000 dollars
Solar systems 200,000 dollars
Maintenance 300,000 dollars
Glazing 100,000 dollars
Insulation 100,000 dollars
Tank 50000 dollars
Total estimated cost 850,000 dollars
Estimated Budget 100,0000 dollars
7.0 Decision to Refurbish or DemolishThe decision of refurbishing would be based on the market demands as well as the type of business practice which is carried out in the budget. The budget is present in a higher amount, and it can be afforded to add new features to the building. One of the important factors is the location of the street in West Melbourne. This building is a home to corporate offices as well headquarters which cannot be removed from the location. The building would provide an option for the tenant as well payback period for the owner would be higher CITATION Ber185 l 1033 (Berg amp Fuglseth, 2018). Return of investment would be covered within four to ten years and would not burden the place owing to geography.

Excellent Good Reasonable Awful
Building Performance Excellent Level 1 Good Level 2 Reasonable Level 3 Awful Level 4 8.0Selecting upgrade initiatives8.1 HVAC systemsOne of the upgrade initiatives is based on the HVAC system. It is the key requirement of the building to install the air conditioning system on the ground as well as first and second floors. The common justification for this upgrade is to reduce the loss of energy and maintain a central system of heating and cooling. Cooling cooperation would be involving the supply of fresh water to the building and reduce the consumption of energy. This would also include the services of boilers as well as water radiators.
Second upgrade initiatives would be reducing a load of energy on existing systems. This would be done using lights which are sensors based. Lights will switch off when the rooms are unoccupied in the building CITATION Fer15 l 1033 (Ferreira, Pinheiro, amp De Brito, 2015). Colour schemes would be upgraded to increase the amount of internal reflection.
Waste production would be upgraded on the base of prohibited materials. The concept of green energy initiative would be adopted as a recommendation for retrofitting the building to client specification.
8.2 Upgrade BenchmarksBenchmarks for the building design and addition are made of the heat ventilation system. The main goal is to reduce the amount of energy consumption and replace renewable energy methods for cost and productivity.
The second benchmark is to install solar panels for water heating and energy generation. This would be achieved with the help of an energy efficiency rating.
The third benchmark falls in the area of transport and logistics. The material required for upgrading walls as well as floors will increase the cost of the project and aim to affect the energy rating.
8.3 Report AssumptionsOne of the prominent assumptions is the need for retrofitting for a building which has the potential to raise the tenancy and increase the business activities in a particular region CITATION Mic15 l 1033 (Miccoli amp Fontana, 2015). The period of rent, as well as spaces for corporate offices, would be assumed as the main requirement for the present project.
9.0 Conclusion and RecommendationThe report was made on the present condition of the building located on 115 Batman Street, West Melbourne. The buildingwas sound in terms of structural integrity and finishes are well present on the ball. However, some Ares of the building requirement refurbishment includes heating, cooling as well as the logistics system. According to the NABERS energy rating, energy performance should be present in five-star rating. In order to raise the current standards of building some of the additional improvements were recommended for the building. This includes the replacement of HVAC systems as well as lightening controls and construction materials. The installation of solar panels also included in the retrofitting of the building.
Building requires a minor amount of refurbishment. The total cost of the project was two million US dollars, and it represented the construction of external facades as a wells water tank and building roofs. It was found from the report that building retrofitting can provide more opportunities for the current city. The refurbishing activities for building analyzed the qualitative figures for energy consumption. The building was a good choice for retrofit activities, and the decision was based on the cost as well layout of the location.
It can be recommended for building the challenges for transport should be accounted for the construction process.
It can also be recommended that opportunity is present for investment and return for building renovation. The client should be aware of the specification of HVAC systems and solar panels. The client should also notice that investment can be managed on the requirements of the building as well as the layout of building fronts.
A recommendation can be made in terms of energy as well as waste usage. The owner of the building is required to provide its requirements and principal budget regarding the design of building and technologies which would be used for the refurbishing process.
