Structure A courtyard is chosen as a building typology in order to create unifying central gathering space in the heart of the library. For that purpose a building mass horizontally was divided into three semi-equal parts (spans 9m – 12m – 10m), where a middle part is an atrium space. A combination of open spaces is required in order to accommodate building program and provide flexibility. Also the program has stepping up profile in the section (2 levels on the North side and one level on the South) and at the same time includes an accessible roof top garden. Considering a potential books load and children’s active behavior, the Post-and-Beam structural system seams the most appropriate, allowing an equal distribution of loads and a flexible floorplan.

Taking into an account an idea of creating a Leaning Space which also will be teaching an environmental values, wood was chosen as a locally available ecological material. Having such an aesthetic qualities as natural warmth, texture, color and smell, a decision was made to create an exposed wooden structure space. The glulam wood structure is required in order to run 9m, 12m and 10m spans.

200mmx300mm glulam columns were placed on 3000mx9000m structural grid with 200mmx450mm glulam beams. Instead of diagonal bracing, the same 200mx450m glulam beams were used in combination with adjacent loadbearing structural walls of staircases, for rigidity and thrust between columns.

Following a tectonics of chosen structure, wooden trusses (2m hight, and 11.7mlong) are used to support a roof over the atrium space. In this case monotrusses are beneficial in order to open up atrium space to South sunlight and reflect light into the reading spaces.

60mmx120mm exposed Wood Purlins are used to create structural rhythm in the exposed ceiling and support floor and roof structure.

Concreate strip footings 1 300mm deep are placed below the frost line potentially on a bedrock, in order to equally distribute structural load to the ground and to control the settlement.

120mm concreate slab on grade with radiant heating over concreate foundation is used for the floor system of a ground level. 38mm Wood Deck with 70mm concreate slab with radiant heating over is used for the second level. 64 mm Wood Deck with 2-layer of plywood is used as the base for the roof structure.

Radiant heating floor was proposed as a most appropriate heating system, taking into consideration a diversity of children’s activities. Keeping in mind a desire to have cohesion of exposed wood ceiling and wood heat transfer properties,

70mm concreate slab with radiant heating has to be placed on top of the wood deck.

Simpson Hidden Steel Connectors are used in order to form non distractible illusion for wooden connections, and to create an atmosphere of simplicity and continuousness.

All the partitions are not loadbearing, as well as a building enclosure. Only staircases’ core are self-load bearing CMU walls, placed in between 3mx9m space created by wooden post and beam structure. CMU is proposed as a not expensive, durable, fire and sound resistible material.

Skin and Envelope Design and Strategies Original design intention was to separate structure (support) and enclosure (control), what simplifies maintenance as well as replacement and repair as needed through building lifecycle. Having Glulam Post-and-Beam structure as a support system allows to create self-loadbearing enclosure. Taking into a consideration initial design proposal with long spans of curtainwall or storefront windows, a lightweight system was required. Light-gauge Steel Framing creates self-sufficient enclosure system and connects vertically to the glulam column system by steel framing clips connectors. Which accommodates building movements and construction tolerances, as well as allows for vertical and horizontal movement. Also the use of glue-laminated timber to undergo less drying shrinkage and placing Light-gauge Steel Framing outside of gluelaminated structure instead of “in-between the floor slabs” creates flexibility in thermal movements, construction tolerances, makes the construction process and designing control much easier.

The next step was to apply principals of Ventilated Façade system to the building enclosure, in order to control heat, cold, moisture, and noise. Exterior insulation layer is proposed to be placed outside the steel studs (not in between) for two reasons. First of all, this approach allows to combine water, air and vapor control layers into one (Blueskin SA) and simplifies connections at the joints, windows, foundation and roof, what ultimately leads to more energy and performance sufficient enclosure. Secondly, exterior insulated wall creates free space for services between steel studs in the wall. Control layers are placed between insulation and the wall to protect enclosure against UV, heat, water, and air.

Light-gauge Steel Framing is protected by gypsum board layer against fire, and Fire-Retardant-Treated Wood is used in combination with sprinklers.

Having a rainscreen, an air gap (drainage surface), thermal mass and then wall structural steel-studs system creates a wall mass and provides building with thermal and acoustic insulation.

Created air cavity between the building shell and the façade dries out the structure and allows the building to “breathe” what is essential for cold-dry winter and hot-humid summer conditions.

A light weight cladding material was required due to use of Light-gauge Steel Framing as building enclosure. Corian Exterior Cladding panels is a solution to light weight, thermal control, and weather resistance. The material itself is known for being green, having lower maintenance cost, long lasting and energy saving.

Apart from that, a desire to create a Facade which is a Blank Canvas for Creative Expression helped to decide on applying Corian panels as cladding material. For the same reason, white panels were selected, as a potential surface for engraving and drawing, projection surface, up-lighting and eliminated translucency.

A special attention is paid to the heat control, apart from moisture control, air control, vapor control, accommodation of building movements and construction tolerances. The following steps have been taken: - Exterior insulated wall with Xps Rigid Board Insulation 130mm with ship lapped seams (wall) or double layer of insulation lapped (roof); - Thermal break control; - Triple glassed Kawneer Spectrally Selective Glass high performance windows with 7mm thermal break, R-value = 5; - Reflective glazing; - Window to Wall Ratio: East elevation 36.7%, West elevation 32%, South elevation 38%, North elevation 23.5%; - Exterior shading devices and roof overhang on the South elevation; - Reflective properties of Corian panel; - White colored exterior Corian cladding (80% solar radiation reflected) and light colored river washed stone as a roof paving (55% solar radiation reflected) in combination with a green roof system; - Air gap created by ventilated façade system.

Efficient Design Strategies Sustainable design The project seeks to minimize the negative environmental impact of the building by efficiency and moderation in the use of materials, energy, and space development. Making an accent on a conscious approach to energy and ecological conservation in the design, the fallowing components were considered: - Sustainable Energy Use through heating, ventilation and cooling system efficiency and heat pumps system; - Sustainable building materials, application of recycled materials as appropriate.

Lower volatile organic compounds in applied materials as a priority, and utilisation of materials known as sustainable (for instance wood and Corian cladding); - Waste management program through the construction process, as well as through building lifecycle; - Building placement; - Minimizing light pollution (average window to wall ratio 32.5%).

Passive design Through the design development a particular attention is paid to daylighting, natural ventilation, and solar energy, as well as building mass and orientation.

The proposed design has a close to square plan. Such spaces as rooftop garden and greenhouse are required direct sunlight and orientated to face South. The spaces orientated to North have minimal openings (Window to Wall Ratio 23.5%).

Proposed courtyard garden with playground is located on the West side of the building, which is shield from the sun by existing tries. 10 meter buffer zone is provided between the building and the surrounding vegetation.

The spaces, which designed to be quiet, allocated on the west part of the site, distant from busy and noisy Grand Avenue. Public and active spaces, such as café, lobby and learn to read area, are concentrated on the east of the site along Grand Avenue.

The building massing is closely linked with the building's program. The spaces with activity or equipment, which generate relatively little heat from internal loads, have a compact floor plans to avoid losing heat to the outside. This minimizes the ratio of surface area to volume, lowering heat loss to wind and radiant cooling. The densely populated spaces with high kid’s activities (such as play area or lobby/circulation desk area) generate a great deal of heat, causing high internal cooling loads. Thus, design as an advantageous for such spaces to have thinner floor plans, to get free cooling or bigger window to wall ratio. The

spaces which radiate the most heat, such as the cyber zone, offices and the mechanical & electrical room are located by the north wall of the building.

Interior buffer zones are placed in a building's west side to protect working areas from the hot afternoon sun, such as the atrium space, stairs, restrooms and service/storage spaces.

Roof over the atrium is angled for optimal solar heating. In order to receive daylight instead of direct sunlight, the reading spaces are separated from the south opening by the atrium space. Roof overhangs, shading devises and light shelves are adopted on the south elevation in order to create shadow and redirect light from atrium to reading and play spaces.

In combination with operable windows, the open floor plan creates natural cross ventilation and stack effect through the atrium double space. Also in the winter the atrium space creates circulation of heated air by solar heat gain from large south windows.

Butterfly Pinched Roof designed to collect rain water from the roof, which is pumped to landscape, garden and toilet use.

Geothermal Heat Pump is proposed for supplementary cooling in the summer and heating in the winter.

Green Roof provides Cooling Effect in the summer and Waste Diversion, prolonging the service life of heating, ventilation, and HVAC systems through decreased use. Also offers stormwater management, such as reduce the amount of stormwater runoff and also moderate the temperature of the water and act as natural filters for any of the water that happens to run off. Other benefits are: moderation of urban heat island effect and improved air quality, improves energy efficiency, increases roofing membrane durability, reduction of electromagnetic radiation, noise reduction, increased biodiversity. In combination with rooftop garden and greenhouse, the green roof becomes a part of urban agriculture and provides educational opportunities, which are the main accents of this project.

Environmental Systems and Services HVAC system Radian floor heating is responsible for building heating. Ventilating, cooling and air-conditioning are performed by HVAC system. All-Air a dual-duct system is used in order to separate ducks to deliver warm air and cool air to mixing boxes, which contain thermostatically controlled dampers for more energy efficiency.

Combo systems is used as a water heater to provide space heating as well as hot water.

Mechanical space is located on the first floor, placing the core along the north edge of the building. Air-conditioning condensing units are moved to the roof space in order to operate more efficiently when not blocked by vegetation or structures.

HVAC system distribution is exposed and routed along corridors, above service and washroom spaces where possible. Building is cooling dominated in the summer and heating dominated in the winter, due to dry-cold winter and humidhot summer climate. During fall and spring, when climate is mild, the building can be operated passively. Condensation control is not an issue if the air and vapor barriers are property installed and maintained.

Acoustics To reduce noise inside the building, exterior walls were detailed the way to exclude outdoor noise. Also particular attention is paid to detailing potentially noisy components of the building. Airtightness control is performed.

24” resilient channels in partitions are used to reach STC 43 where applicable.

Sound-absorbent materials, such as sound attenuation blanket in partitions, are used to achieve STC 52 within rooms to reduce noise from conversations, kids play and machinery. In order to achieve great acoustic qualities (STC 60 to 64) multiple layers of interior gypsum board are used as required.

Interior doors, glass partitions, floors and ductwork have sound absorbent qualities, as well as acoustical gasket in order to achieve acoustic privacy,. To avoid sound travel through ductwork, the sound-absorbing material is lined where applicable. The same design principal applies to above-ceiling plenums and below-floor service chases.

Resilient matting is proposed to install between the top of the structural floor and the bottom of the finish floor to cushion floor effectively and to reduce transition of impact noise.

Suspended acoustic panels are used to provide additional acoustic comfort in high sound impact spaces, such as the café and the play room/ multipurpose space.

Artificial lighting strategy Having a maximising of daylighting as a priority, environmentally friendly lighting strategies are applied towards artificial lighting for occupants’ health and wellbeing as well as energy saving. Energy Star Advanced Lighting Package is installed in combination with energy efficient light fixtures, such as 32-watt Compact Fluorescent Light Bulb (CFL).

Data transmission, communication Electrical services, plumbing and other communications are run in between steel studs in partitions or in enclosure walls. Double partition system is installed as required (for example for washrooms’ plumbing). Electrical trays are used to run electrical services where applicable in the exposed ceiling.

Transportation 1300mmx1600mm wheelchair accessible elevator is installed. Elevator Service space is located above the elevator shaft with the ceiling high 2100mm and accessible from the west stair.

Life Safety Health and safety issues addressed in the building design detailing are following: - Safe footings. Accessible flooring transitions, acceptable gratings with attention too doors opening directions.

- Fall protection. Stair handrails and acceptable profiles; guardrail where applicable (such as atrium balcony and rooftop garden); age appropriate library equipment and furnishing.

- Safe edges, rounded corners, no sharp edges, no rough surfaces, non-pinching doors, no exposed electrical outlets in the child areas.

- Safety glazing; etched glass for glass wall partitions; use of laminated glass in the curtain wall, cafe store window and the playground facing windows.

- Use of non-toxic materials and monitoring of interior air quality system.

- Use of fire-safe or fire- treated materials and providing fire-resistant assemblies for the structure.

There are two emergency stairs in the building which have a direct exit to the streets – one to the Grand Avenue and the other to the Blair Street. The distance between the stairs is less than a half of the diagonal of the building perimeter, and equal 16.5 m. Egress width are design in compliance with occupancy capacity, and no dead end corridors are occur in the project. Egress doors and exit doors operated by the panic hardware.

Mechanical and Service spaces have a restricted access lock.

Barrier Free Design Easy access from the ground level into the building with the clear route through the building with accessible ramp exiting to the playground is provided as a barrier free design. Nearby parking includs designated accessible parking spots.

All the doors leading to the public spaces are barrier free accessible. Accessible doors and entrances are assured by regulations that relate to signage, clear widths, types of floor surfaces, wheelchair maneuvering clearance, vestibule and airlock size and configuration, door hardware, door closures, door opening force, and automatic doors with push-up bottoms.

Barrier free stair-raiser profile is applied. Accessibility regulations furnish minimum dimensions and details for wheelchair maneuverability in interior doorways, vestibules, corridors, and washrooms. All the washrooms are barrier free with one wheelchair accessible unit on the first floor, as by OBC requirements for designed occupancy capacity.

Circulation desk and the café counter is designed with lower sections for the use of wheelchair users as well as smaller kids. Drinking fountains are design to meet accessibility requirements.

In order to aid persons with visual disabilities, surface materials and colors of important building features are designed to differentiate from their surroundings using contract, as required.

Environmental Site Strategies At the initial design party stage a relationship between the proposed corner situated site and adjacent neighbor sites was established. A shared green space zone is created among sites by connecting existing vegetated areas at their backyards. This later influenced a decision to allocate building along Grand Avenue and Blair Street and leave intact green area at the south west corner of the site. A courtyard garden with kid’s playground is proposed in this area.

As plant materials provide aesthetic and functional benefits in conserving energy, framing or screening views, moderating noise, and retarding erosion. Existing vegetation at the west edge of the site is proposed to be preserved. New trees will be planted where required.

The free of pavements area on the site is proposed to be planted with grass, as a way to aid in stabilizing soil embankments and preventing erosion.

Rigid pavements are used by the front entrance and the café area, in order to distribute loads internally and transfer them to the subgrade over a broad area.

Reinforcement and extension of the base material is required. Flexible pavements are used in the back garden with the playground area, as big loads are not expected. Stone is used as a pavements material with steel edging to resist horizontal movements of pavements.

Handling of water and drainage strategy is to limit disruption of site’s natural water hydrology and promoting infiltration by such means as pervious paving.

Also controlling site drainage in order to prevent erosion and collecting of excess surface water or groundwater resulting from new construction.

Subsurface drainage system is proposed, as an underground network of piping for conveying groundwater to a point of disposal. Foundation drain system is used to collect water by the foundation wall.

Finished grades are sloped 5% to drain surface to guide water away from the building.
