Sustainability and Environmental Response; 1.Service spine-the key environmental design element of this design is the Service spine that runs vertically and horizontally throughout the structure, holding heating and cooling ducts, electrical wiring, and rainwater systems. This centralised spine decreases energy loss and promotes a sustainable building management system, allowing for more effective, accessible maintenance and servicing from each floor. Its interconnection from the bottom floor to the topmost level ensures a consistent building performance.
• Heating and cooling strategy
• Rainwater harvesting
• Rainwater recycling
• Low carbon foot print
2. NATURAL LIGHTING- The building uses controlled natural lighting techniques considering Malta’s high level of solar exposure. The galleries with a sawtooth roof is oriented to get mixed of northern and southern light, which is best to have true colours of paintings.

•Light pipes are located on top of the cliff to get natural light inside the excavated chambers.
•Ribbon Windows and Vertical Narrow windows Are placed to have adequate lighting and capture views.
•Light wells to have natural light while keeping the most of the walls free to display art.
3. Cross Ventilation- Strategic placement of openings, vents, and transitional spaces (such as verandas and atria) allows for passive cross ventilation. The cliff-side entrance, open terraces, and enfilade arrangements promote air circulation across the galleries, reducing the need for mechanical ventilation.
4.Heat Recovery Ventilation & Air Conditioning
The building uses a mixed strategy of natural ventilation and mechanical systems. Cool air is drawn from underground tunnels and circulated through vertical ducts inside the service spine, passively cooling the building. A Heat Recovery Ventilation (HRV) system is integrated to reuse the cooled indoor air before it’s expelled, reducing energy use. During warmer months, an efficient air conditioning system supports this setup to maintain comfort. This approach lowers operational energy demands and supports a low-carbon footprint.
5.Recycled Limestone; Recycling the existing limestone from the site in the excavation process, The tunnel inside the cliff involves lots of lime stone, these lime stone will go through various recycle process to make it stone masonry blocks to the building. . This reduces the building’s embodied carbon footprint and promotes circular design principles.
6. Naturally Cooled Archive;
Carved into the cliff, the archive benefits from the geological insulation provided by the earth. This method keeps the temperature steady and low, which is good for art preservation and reduces the need for energy-intensive climate management.
The archive space is passively ventilated through ducts connected to the service spine, which pulls cooler air from the underground tunnels.
low-energy dehumidification system, activated only when relative humidity exceeds ideal preservation levels.

7. Photovoltaic Panels ;Solar panels are installed on the upper roof levels, and the massive building next to the scheme
8.Waste Management Strategy-
Waste sorting stations and collection points are integrated discreetly into service areas. Greywater from the building is filtered and reused for irrigation, and organic waste from the café is composted on-site.
9.Mobility & Accessibility
Universal design principles are embedded throughout, with accessible ramps, elevators, and step-free connections between all public levels. The Marsa lift from the masterplan provides a direct, barrier-free link from the ground floor (0mm) to the top park level (+17m)
The rear of the building has direct service access to the road, Lorries can access closer to the Service door, from there can access to the service lift, which makes the artworks transportation easy.
11.Cliff Terrace- A key public space at the summit, the cliff terrace combines views of Marsa Harbour with passive climate control features. Its rubble walls, shaded seating, and stone paving cool the space naturally while accommodating visitors in comfort.
10. Trees & Solar shading- Solar shading in the design is achieved through a combination of architectural overhangs at the cliff terrace and strategically placed deciduous trees. The overhangs reduce direct solar exposure on glazing and terrace areas, particularly during summer when the sun is high. In parallel, deciduous trees are planted along pathways, near the entrance at the ground floor, in the courtyards at the level 3. These trees provide natural shading in summer while allowing solar penetration during winter when they shed leaves.
