Green Data Center Design and Build Strategies

Chapter Description

This chapter discusses methods for limiting the environmental impact that occurs during the construction of a Data Center through decisions concerning physical location, choice of building materials, landscaping choices and jobsite construction practices.

Although not frequently given much consideration when planning a Data Center project, landscaping—encompassing not only lawns and vegetation but also the artificial surfaces on a property—has a significant effect on how green your facility is, influencing building heat loads, water usage, air quality, and other conditions.
Be strategic about what you plant on your land and where. That means not only using drought tolerant and low maintenance plants, but also placing trees in key locations to shade buildings and areas that can otherwise absorb and store unwanted heat, such as parking lots.
If your Data Center project involves building new structures, or expanding existing ones, don't indiscriminately move earth and demolish trees and other vegetation. The goal is to minimize disruption to the land and, where possible, reintegrate natural components. For instance, if you need to remove trees during construction, try to replant them elsewhere on the site.
Figure 3.1 shows workers relocating a tree to make way for Data Center construction. The tree was moved to a makeshift tree farm on the building site, shown in Figure 3.2.

In Figure 3.3, a few feet (one meter) of dirt is excavated from the ground floor of a building to make room for a sunken Data Center raised floor. Figure 3.4 shows the amount of soil removed from the building in a period of 24 hours.

To reduce water usage, avoid pollution, and reduce your maintenance costs, you need to implement good landscape management practices, including the following:
  • Irrigate efficiently: Don't overwater, which not only consumes more water, but can also cause vegetation to grow faster and, therefore, require additional maintenance.
  • Use mulch: Place mulch in planting areas to insulate foliage, reduce water usage, and limit erosion. Where possible, reuse plant clippings or wood waste from your own property as mulch.
  • Leave grass clippings on lawns: Grass clippings decompose over time. This is good for the lawn, providing nutrients from the clippings, avoiding the need to dispose of the green waste, and reducing water and fertilizer usage.
  • Limit pesticide usage: Consider solutions for controlling unwanted weeds and insects that don't involve chemicals so as to maintain good air quality.
  • Avoid excessive pruning: Pruning can trigger faster growth, requiring additional maintenance activity.
Be aware that many green elements that are effective for the exterior of your building can also be incorporated onto your overall property. For instance, the same advantages of implementing a cool roof—lowering energy consumption to cool a building and reducing heat islands—can be gained by implementing cool pavement, consisting of materials with high solar reflectance and thermal emittance.
Likewise, photovoltaic components can be installed on your property to harvest solar energy. Solar canopies for parking lots can perform double duty at a building site, both generating electricity and providing shade for employee vehicles. Street lamps are also available that can be powered by solar energy alone or by a combination of wind and solar energy.
Consider using pervious concrete or porous asphalt for paved locations on your property such as sidewalks, parking areas, and curb and gutter systems. Unlike conventional paving, pervious materials enable water to seep through. This reduces storm-water runoff, helps recharge groundwater, and better transfers cooler temperatures from the earth below to the pavement, reducing heat island effects. Rubberized asphalt, mentioned at the beginning of this chapter as a green material because it uses ground up scrap tires that would otherwise end up in landfills, is available in pervious form.
You can reduce water usage at your site by collecting and storing rainwater, using it for nondrinking activities such as watering vegetation and (after treating the water) flushing toilets. Rainwater harvesting equipment consists of a catchment (typically atop a building roof) to collect the water, a distribution system (angled roof features, gutters, downspouts), and a container to store it (a cistern).
How much water can you expect to collect? That depends upon the size of the catchment and how much rain falls in the region. To make an estimate, multiply the size of the collection area by the average amount of rainfall for a given period.
For instance, if your catchment area is 20 feet long by 50 feet wide and the area receives 24 inches of rain per year, that's 20 feet x 50 feet x (24 inches / 12) = 2000 cubic feet of water. Multiply by 7.48 to convert to gallons; 2000 cubic feet x 7.48 = 14,960 gallons.
Using metric figures, that's a 6.1 meters x 15.2 meters x (61 centimeters / 100) = 56.6 cubic meters of water. Multiply by 1,000 to convert to liters; 56.6 cubic meters x 1000 = 56,600 liters. (Note: The end calculations of 14,960 gallons and 56,600 liters don't convert exactly due to rounding of metric measurements.)
This is an idealized number because it does not account for water spillage or evaporation, both of which reduce the total water yield.

Timer AC bergantian

Bagaimana sich prinsip kerja AC yang bergantian? Seperti yang terangkai pada ACPDB, yang kita butuhkan adalah 1 buah timer dan 2 buah kontaktor. Pada dasarnya rangkaiannya adalah seperti gambar diatas. Seperti kita ketahui, timer dan kontaktor akan bekerja apabila mendapatkan catuan 220 V. Pada timer catuan bisa dikoneksikan di lubang “L” dan “N”, sedang pada kontaktor dilubang “A1” dan “A2”. Itulah kenapa pada saat mati listrik komponen2 tersebut tidak bekerja. Timer berfungsi sebagai switch dari 2-1 atau 2-3 dan lubang “2” sebagai sumber yang dialiri arus listrik. Sesuai namanya alat ini akan bergantian dari 2-1 atau 2-3 berdasarkan waktu yang sudah kita atur pada sirip biru. Satu sirip merepresentasikan 30 menit. Sedang pada kontaktor untuk tipe Telemecanique, sumbu-sumbu saklarnya adalah 1-2, 3-4, 5-6, NO-NO, NC-NC.  Jika “A1” dan “A2” tidak dicatu maka 1-2 (open), 3-4 (open), 5-6 (open), NO-NO (open), NC-NC (close/terhubung). Dan bila “A1” dan “A2” dicatu  maka 1-2 (close), 3-4 (clo…

Pemilihan jenis modul AMF (Automatic Main Failure)

Pemilihan jenis modul AMF (Automatic Main Failure)

Dari sekian banyak jenis modul yang ada dipasaran, kami menawarkan beberapa alternatif untuk jenis modul AMF yang dapat kami sediakan. antara lain menggunakan modul dari DEEPSEA, smart relay atau timer. tentunya dengan beragam pilihan tersebut ada beberapa keuntungan atau kelebihan dari masing masing modul tersebut. sebagai misal menggunakan modul AMF dari DEEPSEA akan sangat cocok jika modul ini dapat berinterakasi langsung dengan genset. terutama jika mesin genset belum dilengkapi genset controller dan masih mengandalkan panel genset manual. untuk pabrikan genset sekarang ini pada panel genset sudah dilengkapi dengan AMF, sehingga tidak perlu panel AMF - ATS dengan menggunakan modul DEEPSEA atau sejenisnya. sehingga dalam pemilihanya dapat menggunakan timer, smart relay atau produk lain seperti ATS controller C20 dari socomec.

Mendesigns dan Menghitung UPS untuk Data Center

Mendesigns dan Menghitung UPS untuk Data Center UPS dan data center mungkin bisa di sebut sayur tanpa garam, hambar jika tidak saling melengkapi. 
Tapi untuk menentukan kebutuhan akan UPS data centerperlu perhitungan yang matang agar UPS dan server tetap awet dan selalu ON 24 jam. banyak sekali jenis UPS dan daya yang di tawarkan. Kita harus menghitung kebutuhan beban keseluruhan server agar ketika listrik down UPS dapat menghandle beberapa detik untuk listrik pindah ke genset begitu pula sebaliknya, Oke untuk menentukan itu semua tentukan dulu jenis UPS yang akan anda gunakan.
Oke kita sedikit belajar dulu tentang UPS :)
PRINSIP KERJA UPS Setiap PC membutuhkan daya listrik. Apabila aliran listrik (main power) terputus, PC akan mati (tidak berfungsi). Fungsi dasar UPS (Uninterruptible Power Supply) adalah menyediakan suplai listrik SEMENTARA ke beban (PC) tanpa terputus pada saat main power tidak bekerja agar seluruh proses dapat dihentikan dengan benar, seluruh data dapat disimpan den…
