Executive summary
The report was assigned to analyse and evaluate the sustainability of the site. The research and data collected on the day of the visit was found to show the site had made little effort to be a sustainable site. The data that was collected was broken down and analyse to see how the site could become more sustainable. Some assumptions were made, for example that the U-values of the building were below required standard.
The key problems that need addressing are as followed:
– Fix hole or seal the hole on the site.
– Repair the car park.
– Expand the club to make it finically suitable.
– Replace light bulbs to meet standards to increase energy efficiency.
– Check if insulation is adequate to meet U-Values.
– Replace heating and cooling system.
It is recommended that:
– The site gets its electricity from renewable sources by purchasing or obtaining it by setting up a source on site.
– A ground source heat pump to be set up as it is finically and environmentally viable.
– The site to set up extra activities on site so it is used more frequently.
– Development to the sites bar to encourage supporters and public to watch games.
Introduction
A report on the sustainability of the site was undertaken on the 9th of October 2018 at Bellholme Sports Ground located in Todmorden. The reason for the report is to investigate and distinguish the faults of the sites sustainability then followed with recommended remedies to solve the problems pointed out if it were to be put back into existing use. The investigation will also conduct if there are any options of increasing the suitability of the site above the minimum requirement but also taking into account that the site must remain an attractive site but furthermore being finically sustainable.
As shown in figure 1 being sustainable is the combination of 3 elements; social, environmental and economic sustainability.
Social – the conservation of human life; the main focus in this report will be the education, safety and preservation of children.
Environmental – this is making sure that the site is used without diminishing the existing environment and keeping the human trace on the site to a minimum.
Economic – this is focusing on keeping the site in maximum usage furthermore keeping it finically viable.
Social sustainability
Care toward children on site is very important if it were to open again as they would be liable to injury on site. It was noticeable serval safety concerned.
As shown in figure 2 there is a sizeable hole which is a hazard, there may have been a cone for warning, but this is not satisfactory. It is assumed to be a drainage hole. A simple grated cover or a fixed plate with lock would be satisfactory to allow children on site to be safe.
The north side of the site back into a forested area with pool of stagnant water from the drainage system of the pitch as show in figure 3 a simple remedy would be to fence off around this side of the site to block wandering children. This also backs onto my next point of safety, the ease of accessibility from the public to the site. The site is directly adjacent to a public footpath by a canal, so continuing a fence around the perimeter of the site would restrict children from wandering off while also restricting accessibility to the site.
A simple gridded metal fence rather than solid would be the recommend action to take. The reason for this advice is it would be allowing light to flow through the fence giving it an aesthetic look and not letting the site to become a disconsolate image. It also gives the added bonus of being able to attach banners for advertisement. Pictures shown of concept in Figure 4.
An extra idea but not a necessity would be to add after school activities on site, such as sports club, a scout’s program etc. As the location is only 20 mins from the city centre of Rochdale and very close to the town of Todmorden it is in a very good location. The site at its current time is only used for one football team. They have one match a week and have training one time a week so increasing the amount of time the site is being used would be beneficial for the owner on top of being a good use of the property.
Economic sustainability
It was noticeable on arrival that the state of the car park was in a bad state. As shown in Figure 5 there are a considerable amount of pot holes. Leaving the pot holes in the current state they are in could possibly lead to a law suit for damage or injury to vehicles or personnel. Therefore, a law suit could hit you finically as well as bad publicity. A quick remedy as the site is compressed gravel would be to refill it with the same material which is coarse gravel and compress it down . It is straight forward and cheap method.
The car park could also be resurfaced all together. This could improve the standard of the car park and with the right boarding increase the capacity of the car park. The material that is recommended is a tarmac asphalt. The reason for doing this is a document on the UK government website acclaims that “prevention is better than a cure” . Using a tarmac asphalt means that is much more durable and weather resistant with minimum maintenance. A square meter is estimated at £40 the area of the car park is estimated to be 1,722m2 as shown in figure 6, therefore costing an estimate of £68,000. At an initially look the sum seems a considerable amount, leading onto the reason behind this suggested investment. A car takes an average area of 2.4m x 4.8m for a car parking space therefore an area of 11.52m2. An estimate of 60 could be park with adequate spacing. As the site is only a 20-minute journey to the centre of Rochdale a suggestion would be to propose the idea to Stagecoach a private park and ride company that already operates in the Manchester region . An area of the car park could be leased out to the company therefore an opportunity to increase the income of the property as the site is unused for most of the week.
As stated earlier the club has one team, an idea would be to expand the team into a club with multiple age groups. Clubs often have a membership fee that is required to join, this could lead to massive flux of income as this club is one of the only clubs in the local area, so it would be a good estimate to say it would be popular. If they invested in the club a recommend rain cover or small stand to accommodate supporters with a small fee, or even a voluntary payment, to spectate the teams. Post-match food and the bar of the interior could be invested in. On the program is was noticed a half time pie was in the works but potentially a larger variety of options would lead to an increase in popularity of the bar.
Environmental sustainability
Renewable energy
To increase the sites environmental sustainability of the site as a whole would be to set up a renewable energy source. The site upon visit was using electricity and energy from the grid which is often sourced from non-renewable energy sources. The percentage of the gird in total is sourced between 25 and 30% from renewable sources in 2017 as shown in figure 7 the price of renewable sources are falling at a high rate, the cost of energy from sources from offshore turbines have dipped and are now officially cheaper than buying from a nuclear energy.
There are two ways to improve the environmental sustainability. Buy the energy from a renewable source such as an offshore wind turbine or invest money in building an onsite. The types of renewable energy are as followed:
• Solar – powered by solar panels to produce electricity or warm water
• Wind – powered by turbines producing electricity or helping pump water
• Biomass – Burning off food waste, human waste etc.
• Geothermal power – energy from the heat from the soil/earth
• Hydroelectric – energy generated from the flow of water
Some of these methods would not be useful for the site and the site is not suitable.
• Solar – as the site is situated in a valley this limit sunlight hours and therefore would not be a sustainable method.
• Biomass– expensive operation, scale operation needed
• Hydroelectric – This method could be used if an arrangement with the owner of the canal as there is technology in place that is using slow flowing water to generate electricity. The stream that is also present on the site is too small for anything to be set up.
Wind energy
One of the most suitable methods would be building wind turbines on site. Not on a large scale but small ones can be cost effective and also a way to increase your environmental sustainability. Valleys produce morning breezes when warm air rises on the sides. This creates a convection current producing a wind flow, at night this process swaps meaning that the wind turbine could operate 24 hours a day but also could be used when common wind is in motion which would be suitable for a small turbine. The average wind in the area is 9.2 as shown in figure 8 .
A pole mounted wind turbine that has an output of 6kW costs £23,000 which includes the cost of being installed . The average household requires at least a 5kW of power to operate . It can be assumed that the site will not require this much power and it will also not be in use the majority of times. At an estimate it will use a max of 3kW as the plot only contains a small kitchen and the rest would power the lights.
The government have set up a scheme which means you can sell energy back to the grid. The rates that they buy energy back. The government would only buy 50% of what is generated at 4.85p per kW . Other company’s such as EDF will buy it for 7.64p per kW if you install an export meter, this cost around £250 including installation cost.
This could mean you would save around £319 per year on electricity . Then with 3kW left over which is 1,095kW per annum. Therefore, you could sell back 1,095kW at a rate of £0.0764 equalling a total of £83.658. Consequently, you would make an estimate of £400 per year.
At the cost of £23,000 of the turbine itself you would make back in 57.5 years. But this is assuming that the tariff of energy cost of being bought as well as the cost of purchasing energy from the grid would not increase which it inevitable would, so it can be estimated it would be shorter. A pro of installing a wind turbine is also to decrease your carbon footprint. On average a wind turbine generating your electricity would decrease your footprint by 5.2 tonnes of CO2 a year. Hence, it can be argued that this remedy would be an efficient step in improving your environmental sustainability.
Geothermal energy
Enhancing the use of geothermal energy is a good way to slash or even eradicate gas bills. The process that would be used would be using a ground source heat pump system. This pumps water with a small amount of anti-freeze around a pipe that is buried on your site. The process that occurs is the heat from the ground is absorbed into the pipes and the liquid and it transfers the heat into the ground. The ground stay at the same temperature throughout the year so it can be using constantly. The larger the loop and pipes installed increases the effectivity of the system. As the site is on a large playing field it would be suitable to use this system.
There are two types of ground source heat pumps:
1. Horizontal – this is installing pipes horizontal so therefore it requires more land which is not a problem as the site isn’t is on the large scale. Estimated cost – £1,500-2,500.
2. Vertical – This requires digging vertically down, this is considerably more expensive, but on the other hand it uses less space. Estimated cost – £2500-3,600.14
The actual pump itself will cost between 2,000 and 6,000 depending on the scale14. Then the cost of installing cost between the region of £3,000 and £4,000 This leads to the whole cost of the operation between £5,500 and £11,500. But as this is a fairly small operation it can be assumed that the cost will be on the lower end of the estimated figure.
Figure 1014 shows that a ground source heat pump cost around £975 to run. This can be compared the £2000 it cost to run a standard boiler system. There is also a domestic renewable heat incentive that has been set up that rewards you from using sustainable sources to heat your property, this figure is £4,300 per year. Hence the payback time for installing a system is 4 years. Then after this time period you are saving future costs of purchasing gas and oil from the government.
The pump also works in the summer as a cooling system through the means of conduction from the house into the pipes.
Approved Document L
Approved document L is split into four documents, as this building is already existing and not classified as a dwelling approved document L.1.B. The premise of this documents is the conservation of fuel and power. It states improvements that are practical and feasible.
Improving the heating or cooling system if it is more than 15 years old – this was already covered in the previous point with the ground source heat pump as it acts as a heating system in the winter and cooling system in the summer, so it regulates the temperature all year round
It also suggests upgrading the lamp efficacy if not adequate. “Lamps should operate with less than 40 lamp-lumens per circuit watt and that serve areas greater than 100m2” . It was unclear on site if all the lamps were up to standard. Assuming they are not up to standard they should be replaced with more energy efficient alternatives.
In figure 13 below it states what the u-value requirement is for each element of the building. It was noticeable on arrival that the temperature of the building was similar to the outside and I am taking an assumption it is not up to standard. In figure 11 and 12 you can notice it seems as a very botched job as the insulation has not be laid out well to be as effective as it should be on top of the insulation of pipes is patchy. Improving insulation would mean less energy wasted and therefore paying less for energy because you require less.
The windows were single glazed onsite and therefore lead to a high amount of heat loss. A simple and cost-effective remedy would be to replace the windows with double glazing. To replace all the windows, as there are 5 windows with 2 large pane doors it can estimated cost around £8,000 . To estimate how much would be saved appropriately you would need to fully insulate the property. The next problem that was found on site was the air tightness, crack beneath doors were found with some draft protector installed but were damaged and not up to standard. Draft protectors can be a cheap method of insulating your house efficiently and be cost effective.
