Lighting
• Full upgrade of lighting to high efficiency LED luminaires throughout the building
• BCO 2023 and LG7 compliant for the tenant office floorplates
• Aesthetic roof terrace lighting to ensure safe access and progressing through the space

Lighting Control
• Real-time dynamic automatic controls using IoT technology to minimise energy usage across the floorplates
• Maximise the use of natural daylight throughout the floorplates

Heating and Cooling
• New VRF system to be installed throughout office floors which include fan coil units routing to linear grilles
• Condensers to be located at roof level
• High efficiencies gained by VRF system lowering energy costs.

Ventilation
• Fresh air is 14 l/s/person (+10%) based upon 1 person per 8m2
• Filtration within the air handling units includes both bag and panel filters for pre filtration and final filtration
• Air Handling unit heat recovery provided by a run around coil with efficiencies of up to 60%

Renewable Technology & Efficiency
• All Electric Building
• Photovoltaic (PV) Panels are to be installed at roof level
• ASHP air-to-water technology provides hot water to the new basement end of trip facilities
• BMS energy monitoring system proposed
• PIR control for water shut off and usage efficiency
• Leak Detection to prevent water loss
• Daylighting linking and occupancy controls

Potable Water
• Large potable water tank located at basement level which services all toilet outlets and hot water heaters throughout the building

Plant Locations
• Roof Level – Condensers & PV Panels
• Basement Level – Transformer, Main LV switch room, air handling unit, ASHP, Potable water tank
• Floor Levels – Hot water heaters
• Tenant Comms room equipment space reserved within basement for future use
• Space allocation on the 4th floor tenant for kitchen installation with riser space for kitchen extract ductwork

Sustainability Certifications: BREEAM and Nabers
• The refurbishment of 99 QVS will achieve a BREEAM rating of Outstanding. The project is currently on-track to achieve a BREEAM rating of Outstanding
• The refurbishment project is also undergoing a Nabers Design for Performance process and is targeting a Nabers Energy rating of 5 stars at the design stage

Energy Efficiency
• By upgrading the roof fabric, installing a solar photovoltaic system, implementing high-efficiency HVAC and lighting technologies, and replacing the gas heating solution for hot water with an Air Source Heat Pump (ASHP), we target achieving a reduction in Primary Energy Demand (PED) exceeding 70%. These measures will also result in an improved EPC rating of A

Water Efficiency
• A rainwater harvesting system will be installed, projected to conserve approximately 85,000 litres of water annually

Adaptation to Climate Change
• Designed to address the issues arising from climate change. The design strategy evaluated the building’s resilience to anticipated climate risks, including extreme weather events, and incorporated robust adaptation measures to ensure long-term sustainability and resilience

Supporting Circular Economy
• The project will reduce waste produced during refurbishment by prioritising on-site material reuse and preparing others for off-site reuse or recycling. By maximising material reuse and recycling efforts, the project aims to divert more than 90% (by weight) of nonhazardous construction and demolition waste from landfill

Sustainable Material Procurement
• Sustainability is a key consideration in the procurement of materials. ‘All materials will be ISO 14001, BES6001 or CARES certified, and all timber will be FSC certified.’

Embodied Carbon
• Opting to refurbish an existing building rather than pursuing demolition and reconstruction results in significantly lower embodied carbon. The commitment to minimising embodied carbon will remain a priority during the construction phase of the project, with a focus on prioritising materials that are less carbon-intensive.

Biodiversity
• The new roof design will include a sedum roof that will serve as a microclimate for insects and birds

Sustainable Transport
• The refurbishment project will promote the use of sustainable and active transportation methods by incorporating a new storage area for e-scooters and bicycles, as well as a drying room and state of the art shower and changing facilities

Wellbeing
• The addition of a Wellness Suite / yoga studio in the basement and the external roof terrace expands the recreational offerings within the building. These features offer well-being benefits for occupiers such as opportunities for exercise or relaxation, social interaction, and connection with nature, contributing to a healthier and more vibrant workspace environment.
