Energy Efficiency & Renewable Technology DPS

This Dynamic Purchasing System (DPS) has been established to support the inspection, repair, and replacement of energy efficiency measures and renewable technology installations.

The DPS will operate independently but will complement the LHCPG N9 framework, ensuring that a comprehensive range of renewable and energy-efficient solutions are accessible. The scope of this DPS includes:

• Heating and ventilation
• Electrical energy systems
• Insulation
• Metering and controls
• Emerging technologies
• Multidisciplinary services

The aim is to provide contracting authorities with a flexible route to procure innovative, low-carbon solutions that align with sustainability goals, funding requirements, and regulatory compliance.

Given the evolving nature of the renewable energy sector, this DPS has been structured to allow for future expansion, with the flexibility to introduce additional lots in response to market demand. This ensures that emerging technologies and government-backed initiatives, such as hydrogen heating, BIM solutions, smart metering, and multidisciplinary renewable projects, can be incorporated without requiring a new procurement process. In line with Public Contracts Regulations (PCR) 2015, any future modifications will be transparently managed, ensuring compliance while maintaining an agile approach to procurement. Through this DPS, public sector bodies will have access to qualified suppliers who can deliver high-quality, energy-efficient solutions that contribute to decarbonisation targets and environmental sustainability.

Regular inspection and maintenance of heating, ventilation, and air conditioning (HVAC) systems are essential to ensure efficiency, air quality, and system longevity. This includes inspecting components, cleaning filters and coils, testing controls, and addressing any issues with refrigerant levels, ductwork, and drainage. The following works are included but not limited to:

-Routine Inspection

Inspecting all system components, including fans, motors, belts, and controls, checking heating and cooling units for proper operation, and examining ductwork for leaks, blockages, or damage.

-Filter Replacement

Replacing or cleaning air filters regularly to prevent dust and debris accumulation, ensuring unobstructed airflow and maintaining indoor air quality.

-Cleaning Coils and Fans

Cleaning evaporator and condenser coils to remove dirt and debris, maintaining system efficiency, and cleaning fan blades to ensure effective airflow and operation.

-Checking Refrigerant Levels

Inspecting refrigerant levels, identifying potential leaks, and repairing any detected leaks before recharging refrigerant in line with environmental regulations.

-Inspecting and Testing Controls and Thermostats

Testing thermostats and control systems to ensure accurate operation, calibrating thermostats where readings are incorrect, and verifying system responsiveness to temperature changes.

-Ductwork Inspection and Sealing

Inspecting ductwork for leaks or damage, sealing any leaks with duct sealant to prevent conditioned air loss and improve overall energy efficiency.

-Belt and Motor Maintenance

Inspecting and replacing worn belts, lubricating motors and bearings to reduce wear and ensure smooth operation.

-Drain Line Cleaning

Cleaning condensate drain lines to remove blockages and ensure proper water flow away from the HVAC equipment, preventing system damage and water-related issues.
