Energy efficient comfort air conditioning

Legacy buildings with a total built-up area exceeding 15,000 square meters pose significant challenges to the Facility Management team in accomplishing transformative energy efficiency objectives. An evaluation of the existing energy performance of building services, coupled with a comprehensive, value-added transformative action plan regarding operational procedures and capital investment in retrofit engineering projects, is crucial for enhancing energy efficiency. This article centres on the HVAC system, which accounts for approximately 45-55% of the total energy consumption in a typical fully air-conditioned commercial building operating 24/7, 365 days a year.

The energy components of an HVAC system in a commercial building are

  • Ventilation system (~30-35%)
  • Cooling Plant (~25-30%)
  • Heating (~15-20%)
  • Pumps (~10-15%)
  • Cooling Towers (~5 – 10%)

(Reference:: www.energy.gov.au; hvac-factsheet-basics-energy-efficiency)

What is Thermal Comfort?

Thermal comfort is defined as that condition of mind which expresses satisfaction with the thermal environment.

Acceptable Thermal Environment – a thermal environment that a substantial majority (more than 80%) of the occupants find thermally acceptable.

– American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE – 55,2020)

Balancing comfort and energy efficiency in air-conditioning requires careful consideration. Building design and commissioning using the adaptive method establishes acceptable indoor temperature ranges based on function and climate. Standards like ASHRAE 55-2020, ISO 7730–2005, and EN 15251–2007 incorporate adaptive models, which consider behavioural and technical adjustments, acclimatisation, and psychological acceptance.

Six influencing factors of comfort air-conditioning in an open-plan office

  • Personal attributes- Metabolic rate (Physical activities), Clothing insulation (Dress code)
  • Environmental attributes – Average room temperature, Average air speed, Average radiant temperature, and Humidity

How Facility Management can facilitate comfort air-conditioning for maximum occupants in a large office space (> 15,000 m2).

Conclusion

In today’s workspaces, feeling comfortable with the temperature is a key part of enjoying your workplace experience. When discomfort lingers, it can significantly impact productivity. That’s why energy-efficient air conditioning is so important; it adds significant value that the facilities management team can bring to any building. With thoughtful planning and innovative measures, even older buildings can see a remarkable transformation.

Optimising Service Efficiency: A Deep Dive into Facility Performance

Facility performance plays a crucial role in ensuring the success of both business and residential operations. To provide efficient service, facility performance must align with intelligent design and construction, effectively meeting the objectives of its intended use throughout its operational lifespan. Furthermore, constructive customer feedback, backed by a continuous improvement program, helps to achieve business objectives and prolong the facility’s useful life.

  1. Why is the assessment of facility performance necessary?

Evaluating facility performance, whether focusing on a single phase or multiple phases from design to post-occupancy, plays a crucial role in controlling design development, construction, asset management, and capital investment projects throughout their operational life. Assessing gaps in the infrastructure, asset management relative to functional needs, business requirements, and user perceptions- both internal and external- can create a foundation for necessary adjustments in financial and non-financial aspects.

A balanced scorecard approach incorporating four domains can provide a structured framework for planning corrective actions and ongoing improvement initiatives.

BALANCE SCORECARD FOUR-DOMAIN APPROACH

  • POSITIVE CUSTOMER EXPERIENCE
  • PROCEDURES
  • PROFICIENCY
  • PROFIT
  1. What are the key objectives for evaluating the performance of a facility or a group of similar facilities?

The objectives of the ‘Facility Performance Evaluation’ are established in alignment with the business goals of stakeholders. In a broader context, the key parameters are determined in consultation with the property owners and tenants of the facility, with the aim of maximising benefits derived from facility survey observations and analytics. This approach facilitates informed decision-making regarding capital-intensive projects to enhance operational efficiency, expand, or modify building infrastructure and improve market branding and competitiveness. The four-domain balanced scorecard approach quantifies performance quality.

A systematic process can be developed to establish goals that align with organisational objectives, formulate Key Performance Indicators (KPIS), and benchmark performance against historical data and industry standards across all four domains of the scorecard evaluation. Assessing the scorecard across each domain establishes the framework for performance enhancement. Integrating risk assessment with opportunities for innovative solutions will prioritise the improvement program and delineate the organisational culture.

  1. What are facility managers’ common challenges in conducting a comprehensive assessment?

A Facility Manager faces numerous challenges during the thorough performance assessment of a facility, which can be summarised as follows:

  • Information Gathering. In most instances, the facility preserves historical and contemporary information in disparate repositories, managed by stakeholders who do not necessarily share similar business objectives.
  • Data verification. Authenticity and verification of relevant data points without validation, supported by a sound technological system.
  • Analysis and correlation. The analysis and correlation of available information and data points with the functional requirements established during the pre-design and design development stages, the transformation of property usage over an extended period, the management of perceptions, and the cost inputs.
  • Absence of an appropriate skill set. Inadequately skilled in-house personnel are unable to perform the facility performance assessment.
  • Upper management lacks interest in allocating funds and initiating the assessment program.
  1. Who are the stakeholders who will perform the facility performance evaluation?

A comprehensive Facility Performance Evaluation program will necessitate the professional contributions of subject matter experts, alongside a holistic analysis conducted by the Facility Manager. Consequently, it is essential to engage Architects, Structural Consultants, Mechanical, Electrical, and Utilities Engineers, Environmental professionals, Fire and Life Safety experts, as well as Customer Relationship, Finance and Procurement specialists, thereby establishing a core audit team. The composition of this team will be influenced by the size of the property, its complexity, and its business importance. An in-house team may be trained to execute this process regularly following an initial professional assessment. Work method statements tailored to meet the property’s specific requirements can be revised and utilised for subsequent activities.

  1. Which model of Facility Performance Evaluation should the Facility Manager opt for?

Facility performance modelling is specifically designed to address compliance deviations from building codes and ensure regulatory compliance, while also developing solutions that pertain to fire and life safety, occupancy requirements, future demolition and modification plans, end-user satisfaction, operational procedures, and the professional development of operating staff. The evaluation model is contingent upon the property’s layout, use-specific criticality, the condition of the building’s fabric, and the quality of the interior environment. Commencing with coordination meetings involving stakeholders and conducting walk-around assessments, the Facility Performance Evaluation (FPE) model may encompass, but not be limited to, commissioning or functionality acceptance tests, operational condition assessments of building components and equipment, as well as an evaluative checklist to solicit customer feedback.

The selection may encompass a singular approach or a combination of the four-domain framework of the balanced scorecard, with the objective of enhancing the facility functionality and serviceability, facility management and service quality, addressing or minimising deviations from design and regulatory requirements, implementing investment-grade improvements, and developing the knowledge base of service providers.

A typical facility performance evaluation (FPE) model can include common service elements and individual need topics, and more, as indicated below.

  • Location, Access, and Wayfinding
  • Fire and Life Safety
  • Legal and Regulatory compliance
  • Protection of individual property
  • Building fabric condition- structural and architectural
  • Aligning building aesthetics with brand image
  • Change and churn management
  • Water, Energy, and Waste Management
  • Interior Environment Quality
  • Building systems and sub-systems – HVAC, Electrical, Plumbing
  • Operations Digitalisation and specialised communication and surveillance systems
  • Space Management
  • Ergonomics
  • Cleanliness
  • Transportation Management
  • Special Amenities- Wellness management
  • Sustainability
  • Business continuity
  • Occupants’ satisfaction

The ASTM (2000) standard delineates the evaluation of customer requirements pertaining to facility functionality and quality, while also facilitating comparisons with building design and service levels. Performance levels are explicitly defined to address the needs and expectations of facility occupants. The suitability of a facility for a group of occupants or disparate groups of occupants is categorised based on an assessment of serviceability, condition, and residual service life.

Categories A to D are as follows:

A = OK at present.

B = Thresholds and/or 10% to 30% of topics miss significantly.

C = Serious problems, but not immediate.

D = Immediate action needed, e.g. for health or safety.

  1. What are the derived benefits of conducting an effective and sustainable performance evaluation?

The outcomes of the Facility Performance Evaluation (FPE) can yield numerous potential benefits, categorised into short-term, medium-term, and long-term impacts. Facility-specific tailored FPE aims to enhance initiatives within the continual improvement program. An effective and sustainable evaluation program can support

  • Identifying gaps in compliance with property and life safety codes and relevant legal and regulatory requirements.
  • Conduct a gap assessment of the functionality and purpose of the infrastructure design with its current status, identifying opportunities for innovative solutions.
  • Establish needs for process improvement and develop processes aligned with sustainability principles.
  • Establish documentation of procedures.
  • Enhance customer satisfaction
  • Support decisions based on information and analytics regarding capital investments in infrastructural projects.
  • Identify the needs for competency improvement among service personnel.
  • Analyse cost performance in comparison to the industry and its historical benchmarks.
  • Improve the market competitiveness of service providers.
  • Enhance the reliability and durability of the property.

Property Manager’s Dilemma: Reusing Treated Wastewater in Group Housing Society

Water is an essential resource necessitating sustainable management practices. SDG target 6.3 focuses on halving the amount of untreated wastewater and greatly enhancing global recycling and safe reuse by 2030. SDG indicator 6.3.1 tracks the proportion of total, industrial, and domestic sewage that meets national or local treatment standards. Water stress affects residential, industrial, and agricultural sectors worldwide. The global platform 50L Home promotes water circularity, resilient water management, and carbon efficiency. According to its observation, “On average, the energy required for household water use is approximately 18% of total energy use in the home, contributing to greenhouse gas (GHG) emissions.”

Why does Property Management need to focus on Water Management?

A strong water management system is essential for environmental and operational sustainability and for safeguarding the health and well-being of communal housing residents. Governmental and non-governmental ecological protection agencies are becoming more watchful of water pollution and consumption. Regulations are continuously being established and updated, aiming at water conservation and environmental preservation. Consequently, housing societies need to develop innovative strategies to ensure the health and well-being of residents while maximising water conservation.

The prevalent challenges associated with transitioning from a disposable wastewater model to a practice of optimised freshwater usage, efficient wastewater treatment, and the reuse of treated wastewater within communal housing water management regimes.

  • Lack of access to adequate clean domestic water
  • Poor monitoring systems for drinking water quality and continuity.
  • Minimal or no recycling and reuse of treated safe wastewater
  • Insufficient metering system for tracking water flow usage.
  • Inadequate understanding of water sustainability issues.

Why is treated wastewater reuse significant for the Housing Society?

  • Reusing treated wastewater is a key approach to achieving water sustainability, as envisioned by 50L Home’s goal of “daily 50L per person that feels like 500L”.
  • Groundwater is depleting at an accelerated rate, necessitating government authorities to implement regulations concerning water extraction hawkishly.
  • City Administrators are dealing with significant water scarcity and environmental pollution, mandating stringent water supply and sewage discharge norms for group housing.
  • On average, wastewater is estimated to account for 80% of the domestic water supply. The target for efficient treatment and reuse of wastewater is 40%, with a progressively higher share of total wastewater generation in the coming years.
  • The energy expenditure constitutes a substantial portion of the overall operational costs associated with water management. Housing societies aiming for sustainability accreditation and certification necessitate implementing adequate water and energy management systems.

Property Manager’s approach

  1. Design Parameters of a Sewage Treatment Plant
  • Challenges for Property Managers
    • Lack of sufficient knowledge regarding design intent and details.
    • Undercapacity of the STP is a common issue within the Group Housing Society.
    • Assessing the design and construction gap poses a significant challenge for Property Management’s in-house team.
  1. Options for Reuse of Treated Wastewater in Group Housing
  • Challenges in Group Housing Society
    • Cultural and perception barriers hinder the acceptance of recycled wastewater for domestic non-potable use.
    • Inadequate maintenance leads to frequent failures in treating grey and black water at the Sewage Treatment Plant. The quality of recycled wastewater supplied to residential units, landscaping, and other usage points deteriorates, leaving end users unaware of the system’s failures.
    • There is also insufficient monitoring of the availability of treated wastewater for reuse.
    • The Property Management team has not effectively established a mechanism to resolve end-user complaints.
      • Reuse options   

3. Choice of Sewage Water Treatment technology

Various technologies have been established in the sewage treatment engineering sphere.

  • Challenges in choosing the right technology–
    • The growing demand for reusing treated wastewater has required the implementation of suitable technology based on operational needs loads from the outset of the construction phase and during any modifications and expansions. Property Management would need subject matter experts to identify the most suitable technology.
    • Subject matter experts and stakeholders must deeply dive into the cost viability of installation, operations, and maintenance.
    • Innovative solutions requiring capital investment are being slowly adopted. A comprehensive risk assessment is essential to building a business case for adopting new technology.

Implementing new technology is intended to achieve specific objectives related to reuse. The selection process for appropriate technology necessitates careful evaluation of both on-site and off-site options, considering factors such as land area (sqm/KL), capital investment (INR/KL), operational costs, reliability, and maintainability.

4. Metering and monitoring the domestic water system

  • Challenges in metering water system
    • General negligence regarding water sustainability is evident.
    • The lack of financial motivations for water conservation resulted in most users relying on unmetered water.
    • Without a metering system, the maintenance team operates on flawed assumptions about water utilisation.
    • Insufficient metering data prevents proactive maintenance and operational measures from being implemented.
    • Consequently, sustainability initiatives and reporting suffer.

In group housing societies, smart meters can be installed to monitor, control, report and analyse water availability and usage and identify opportunities for conservation.

Bulk metering systems should be designed by zone and group consumers within a system or subsystem to conduct a water audit.  This approach will help pinpoint areas where water is being wasted.

5. Service Level Benchmarks

The terms of service level are intended to establish appropriate expectations among service partners and stakeholders. The service level delineates the guiding principles from a design, construction, operations, and maintenance perspective.

  • Challenges arise in the implementation of these standards in setting and effectively implementing Service Level terms are –
    • The design and construction of the sewage treatment plants (STPs) have been inadequately executed to curtail capital expenditures.
    • Financial incentives and sustainability certifications are confined to a few group housing societies.
    • The cost recovery mechanism for wastewater treatment plants’ construction, operation, and maintenance has not been meticulously designed.
    • There is a significant lack of awareness regarding sewage pollutants’ environmental, public health, and well-being impacts.
    • The limitations surrounding advanced technology and innovations to achieve qualitative and capacity-handling objectives are notable.

Service level benchmarks

    • Coverage of Sewerage (100%)
    • Treatment Capacity Quality of Sewerage Treatment Plant (100%)
    • Reuse and recycle of sewage (20%)
    • Cost recovery in wastewater management (100%)
    • Redressal of Customer Complaints (80%)
    • Extent of metering of watering connections (100%)

The Central Public Health and Environmental Engineering Organisation (CPHEEO-India) has outlined standards for the quality of treated wastewater.

6. Water Conservation

    • Promote public awareness concerning water sustainability.
    • Utilise treated wastewater and harvested rainwater for irrigation, toilet flushing, cooling towers, and vehicle washing.
    • Promote the use of water meters or timers among consumers.
    • Implement strategies to identify and mitigate water leakages. Particular attention should be paid to leaking toilets, sink faucets, and showerheads, as these account for a significant portion of water wastage.
    • Minimise the flushing volume of water closets, showers, kitchen sinks, and toilet handwashing facilities.
    • Promote drought-resistant planting alongside efficient irrigation systems.
    • Encourage the adoption of water-efficient appliances, including washing machines and dishwashers.

Sewage water treatment plant operation and maintenance are vital for property management services. The Property/Facility Management team is responsible for maintaining the system, with the primary goal of promoting the environmental sustainability objectives set forth. Whether through sustainability certifications or not, maintaining the STP and repurposing treated wastewater is crucial in contemporary group housing societies.

Trends in technology, etiquette, and safety within high-rise buildings elevators

Elevators are the most vital vertical transport equipment in high-rise buildings. Steam-powered passenger elevators were first installed at the Haughwout Department Store in New York in 1857, and the electric lift came into use in early 1900. Since then, the technology and safety features of passenger elevators have evolved for skyscrapers across the globe. With the advent of modern-day skyscrapers equipped with state-of-the-art elevators, building facility managers are responsible for upgrading their knowledge and understanding of the latest technology trends, safety features, maintenance techniques and passenger comforts.

Elevators are ubiquitous equipment that meets the vertical transport needs of high-rise smart buildings. The right design technology, which addresses building operation needs, maintenance and operational procedures, safety audits, compliance with statutory and regulatory guidelines, and social etiquette, constitutes the key elements for managing the system throughout its lifespan.

Business Continuity Management-Mission Control Facilities (Data Centres, Airports)

Data centres have undergone significant evolution since the introduction of mainframe computers in 1945, leading to the emergence of various types, including Enterprise Data Centers, Multi-Tenant/Colocation Data Centers, Cloud Data Centers, Edge/Micro Data Centers, Hyperscale Data Centers, and Telecom Data Centers. Over the past four to five decades, the digital economy has experienced exponential growth, positioning data centres as pivotal components of the digital ecosystem. The reliability, resiliency, and restorability of utility infrastructure supporting data centres have garnered the attention of stakeholders, designers, construction service providers, and facilities management teams. In response to evolving business requirements, operational teams have refined techniques and procedures, particularly following significant events such as the dot-com bust of the year 2000 and the financial crisis of the year 2008.
Business continuity and disaster recovery are essential organisational procedures designed, assessed, and implemented for mission-critical facilities like Data Centres and airports. Power interruptions, cooling and water system failures and human errors are the predominant causes of operational failures. Facilities Management underscores the significance of disaster recovery and business continuity plans within the Service Level Agreement by attending to safety, legal and regulatory compliances, utility systems, and workforce challenges.

Business continuity strategies

Business Continuity Management encompasses any one-off or a combination of the following strategies:
 Active/Backup Model – Maintaining an active backup site to ensure the continuation of all mission-critical activities.
 Active Split Operations Model – The operations of an affected site may be delegated to multiple remote operating active sites.
 Alternate Site Model – Regularly alternating between primary sites.
 Contingency Model – Arranging necessary resources at the location in case of breakdowns.
In every Business Continuity Model, the ‘Maximum Tolerable Period of Disruption’ (MTPD) ranges from a few minutes to a couple of days annually. The organisation establishes ‘Minimum Business Continuity Objectives’ (MBCO) for each mission-critical asset operating in stand-alone status.

Data Center operations depend on business-critical utilities like Electrical Power Distribution, Uninterrupted Power Supply, Battery Bank, Cabling, Cooling Systems, Water Management, Fire Alarm and Suppression Systems, Security, Surveillance and Access Controls, Suppliers, Specialist Service Partners, and Support Manpower, which necessitate ongoing assessments, upgrades, and validation of risk mitigation strategies.

Business continuity management process flow

1. Program management –
The design basis for constructing electrical power distribution in a data centre is established to maintain the desired levels of availability and reliability of the system. Service level agreements with the service providers are designed to adequately reflect key objectives of business continuity, such as the Minimum Business Continuity Objectives (MBCO), Maximum Tolerable Period of Disruption (MTPD), and Recovery Time Objective (RTO). Generally, a minimum availability of 99.982% for Tier-3 and 99.995% for a Tier-4 level site is stipulated in Service Level Agreements. A specialised team must assess, prepare for, respond to, and manage natural or artificial disasters and system breakdowns. This team coordinates logistics for both internal and external support, prepares budget estimates, and oversees essential crisis management actions.
2. Risk and business impact assessment-
o Safety risk
 An assessment of safety risks associated with the electrical power distribution and cooling system must include comprehensive electrical load flow analyses and short-circuit studies. This evaluation should address the identification of thermal anomalies in electrical nodes, cable degradation, malfunctions of switchgear, incidents involving bypassing or malfunctioning safety interlocks, nuisance tripping, detection of unsealed openings facilitating rodent access within switchboards, and inadequacies in the as-built documentation of the power network. Furthermore, a systematic, integrated testing program must verify the reliability of interconnected fire safety alarms, suppression, access controls, and electrical and ventilation systems.
o Non-compliance and nonconformity risk
 Risk and business impact analysis will necessitate sufficient construction design details, documentation regarding non-compliance and nonconformity with electrical codes and regulatory standards, clearances from local governmental authorities, as-built system drawings, and walk-through observations.
o Operation risk
 Documentation – Inadequate or absence of design and construction details, operating procedures (SOP, MOP, EOP), and troubleshooting charts.
 A yearly system testing program will pinpoint potential risks for sourcing clean, dependable power and uncover opportunities for cost-effective risk management solutions.
 Identify the “Single Points of Failure’ within the power distribution network and cooling systems, particularly those potential failures that may be ascribed to human error and loss of standby redundancy.
 Failure Modes and Effect Analysis (FMEA) evaluation for equipment, components and technology upgrades.
o Environmental risk
 Identify and assess potential environmental hazards, such as
• Flooding of all or part of the site
• Fire or failure to preserve fire suppression system
• Overfilling fuel or containment storage tanks leading to spillages
• Untreated or partially treated sewage water,
• Vandalism
• Pandemics, and
• Water and air contamination.
o Suppliers and support network risk
 Identify and establish priority spare components and equipment based on
• Frequency of failures
• Operational criticality of spare components or equipment
• Cost impact
• Environmental impact
• Expected useful service life of the component or equipment
 Identify dependencies on support resources such as suppliers, outsourced workforce, and other elements.
 Response time and Resolution time SLA with suppliers and support teams.
3. Obsolescence management –
Assess the service life of equipment (Transformers, Diesel Engine Generators, UPS, Battery banks, Switchboards, Static Transfer Switches, Circuit Breakers, Power Cables, Central Chilling plant, Computer Room Air Conditioners, Water Plant, Lifts)
o Condition assessment
 Periodic condition assessment will include tests to identify hot spots, insulation degradation, load flow, short-circuit analysis, and grounding system tests.
 Partial discharge test of VRLA battery bank(s) with a variable load bank.
 Vibration and Noise analysis of rotating equipment
 Electromagnetic field, Acoustics emission tests, Air and water infiltration tests for construction structures and water piping networks.
o Repairability and replaceability of equipment
 Documentation– manufacturer’s manual for diagnostics, disassembly instructions, and repair tips.
