2015 ESOS Guidelines Chapter 6 – Role of Lead Assessor

The primary role of the lead assessor is to make sure the enterprise?s assessment meets ESOS requirements. Their contribution is mandatory, with the only exception being where 100% of energy consumption received attention in an ISO 50001 that forms the basis of the ESOS report.

How to Find a Lead Assessor

An enterprise subject to ESOS must negotiate with a lead assessor with the necessary specialisms from one of the panels approved by the UK government. This can be a person within the organisation or an third party. If independent, then only one director of the enterprise need countersign the assessment report. If an employee, then two signatures are necessary. Before reaching a decision, consider

  • Whether the person has auditing experience in the sector
  • Whether they are familiar with the technology and the processes
  • Whether they have experience of auditing against a standard

The choice rests on the enterprise itself. The lead assessor performs the appointed role.

The Lead Assessor?s Role

The Lead Assessor?s main job is reviewing an ESOS assessment prepared by others against the standard, and deciding whether it meets the requirements. They may also contribute towards it. Typically their role includes:

  • Checking the calculation for total energy consumption across the entire enterprise
  • Reviewing the process whereby the 90% areas of significant consumption were identified
  • Confirming that certifications are in place for all alternate routes to compliance chosen
  • Checking that the audit reports meet the minimum criteria laid down by the ESOS system

Note: A lead assessor may partly prepare the assessment themselves, or simply verify that others did it correctly.

In the former instance a lead assessor might

  • Determine energy use profiles
  • Identify savings opportunities
  • Calculate savings measures
  • Present audit findings
  • Determine future methodology
  • Define sampling methods
  • Develop audit timetables
  • Establish site visit programs
  • Assemble ESOS information pack

Core Enterprise Responsibilities

The enterprise cannot absolve itself from responsibility for good governance. Accordingly, it remains liable for

  • Ensuring compliance with ESOS requirements
  • Selecting and appointing the lead assessor
  • Drawing attention to previous audit work
  • Agreeing with what the lead assessor does
  • Requesting directors to sign the assessment

The Environment Agency does not provide assessment templates as it believes this reduces the administrative burden on the enterprises it serves.

Monitoring Water Banks with Telemetrics

Longstanding droughts across South Australia are forcing farmers to rethink the moisture in the soil they once regarded as their inalienable right. Trend monitoring is an essential input to applying pesticides and fertilisers in balanced ratios. Soil moisture sensors are transmitting data to central points for onward processing on a cloud, and this is making a positive difference to agricultural output.

Peter Buss, co-founder of Sentek Technology calls ground moisture a water bank and manufactures ground sensors to interrogate it. His hometown of Adelaide is in one of the driest states in Australia. This makes monitoring soil water even more critical, if agriculture is to continue. Sentek has been helping farmers deliver optimum amounts of water since 1992.

The analogy of a water bank is interesting. Agriculturists must ?bank? water for less-than-rainy days instead of squeezing the last drop. They need a stream of online data and a safe place somewhere in the cloud to curate it. Sentek is in the lead in places as remote as Peru?s Atacamba desert and the mountains of Mongolia, where it supports sustainable floriculture, forestry, horticulture, pastures, row crops and viticulture through precise delivery of scarce water.

This relies on precision measurement using a variety of drill and drop probes with sensors fixed at 4? / 10cm increments along multiples of 12? / 30cm up to 4 times. These probe soil moisture, soil temperature and soil salinity, and are readily re-positioned to other locations as crops rotate.

Peter Buss is convinced that measurement is a means to the end and only the beginning. ?Too often, growers start watering when plants don’t really need it, wasting water, energy, and labour. By monitoring that need accurately, that water can be saved until later when the plant really needs it.? He goes on to add that the crop is the ultimate sensor, and that ?we should ask the plant what it needs?.

This takes the debate a stage further. Water wise farmers should plant water-wise crops, not try to close the stable door after the horse has bolted and dry years return. The South Australia government thinks the answer also lies in correct farm dam management. It wants farmers to build ones that allow sufficient water to bypass in order to sustain the natural environment too.

There is more to water management than squeezing the last drop. Soil moisture goes beyond measuring for profit. It is about farming sustainably using data from sensors to guide us. ecoVaro is ahead of the curve as we explore imaginative ways to exploit the data these provide for the common good of all.

How Armstrong World Industries is going Cradle-to-Cradle

The Cradle-to-Cradle concept holds that human effort must be biometric, in other words enrich the environment within which it functions as opposed to breaking it down. This means manufacturing must be holistic in the sense that everything is reusable and nothing is destroyed. Armstrong World Industries was the first global mineral ceiling tile manufacturer to achieve Cradle-to-Cradle certification. We decided to take a closer look at how they achieved this.

Armstrong Worldwide Industries has five plants in the UK alone. These produce an annual turnover of ?2.7 billion. They have been making ceilings for more than 150 years. Fifteen years ago and way ahead of the curve it started recycling, and has maintained a policy of not charging contractors for waste ever since. Along the way, it developed a product that can be re-used indefinitely.

The Challenge

Going green must also be commercially sustainable. In Armstrong?s case, it faced a rise in landfill tax from ?8 per tonne per year to ?80 per tonne per year. This turned the financial cost of waste from a nuisance to a threat. It calculated that recycling one tonne of ceiling materials would:

  • Eliminate 456kg of CO2 equivalents by saving 1,390 kWh of electricity
  • Preserve 11 tons of virgin material and save 1,892 gallons of potable water

They hoped to extend their own recycling project by asking demolition and strip-out contractors to join it, so they could reprocess their scrap as new batches of tiles too.

The Achievement

As things stand today, an Armstrong ceiling tile now contains an average of 82% recycled content. Indeed, if they could find more ceilings to recycle this could reach 100%. In the past two years alone, Armstrong Worldwide Industries UK has saved 130,399m? of greenfield from landfill, being the equivalent of 520 skips that would otherwise have cost contractors over ?88,000 to dispose of.

The Broader Context

Armstrong Worldwide Industries is a global leader in water management, and is bent on minimising its reliance on fossil for energy. It has implemented online measurement systems that feed data to its corporate environmental, health and safety system. This empowers it to produce reports, track corrective actions and measure progress towards its overall goal of being carbon neutral.

Next time you sit beneath an Armstrong Worldwide Industries panelled ceiling, spare a thought for how much ecoVaro consumption analytics could contribute to your bottom line (and how it would feel to be lighter on carbon too).

How Westin Melbourne Hotel Trimmed its Footprint

Becoming sustainable is a three-pronged process. You must save money and push the buttons the government is pressing you to. But there?s a deeper, more urgent issue. If your customers mark you down for not being green enough you are heading for trouble. Let’s see how well this hotel is doing.

The Melbourne flagship of the Westin hotel chain boasts 262 spacious rooms with views of Melbourne Square and surrounding theatres, designer boutiques, galleries and national landmarks. The architects included conference facilities, a wellness centre and sundry bars and restaurants. After climate change arrived to stay, hotel management discovered they had inherited a water and energy-greedy monster. Their solution was to measure what was going through their systems, and then progressively cap the building?s greedy appetite.

The Melbourne Westin Hotel could not have achieved results without these metrics. They began by determining key indicators and measuring them. This provided them with criteria to set achievable, cost effective targets in the following key areas of their business:

  1. Water Management ? Demand-based linen and towel recycling, installation of back-washable water filters, water-saving shower heads, dual-flush toilets.
  2. Waste Management ? Conversion to green products, recycling kitchen oil, moving towards a paperless office, recycling everything possible.
  3. Energy Management ? Energy-efficient light bulbs, standby settings for lights, computers, televisions and air conditioners
  4. Stakeholder Communication ? Staff green-team training, guest education, ongoing employee briefings
  5. Strategic Positioning ? Visible, top-down commitment, optimised carbon offsets from clean, renewable energy sources, clearly stated position in the market

Westin?s Melbourne landmark has made good progress towards becoming the green hotel for others to follow. It has adjusted its environmental policies, increased water and energy awareness and implemented tight waste management.

Consumers are already shopping to make their carbon footsteps lighter. Food stores are on the bandwagon although apparel is lagging. Perhaps it’s time you found out just how your company is shaping up. It’s no longer a matter of ?if carbon taxes?. It’s a matter of ?when it does?.

ecoVaro is a software system-in-the-cloud that lets you enter your water and energy consumption and process it online so you can monitor and manage your usage. In no time at all you could be saving money like Westin Melbourne did. Does that sound like something worth investigating?
