GROUNDSWELL HOUSE Cow Bay, Nova Scotia

1 Halifax architecture firm Solterre Design worked closely with their clients to capture the stunning views of the salt marsh and surrounding surf breaks from a glacial drumlin overlooking Cow Bay, Nova Scotia. The result is a contemporary and incredibly energyefficient residence providing the owners with extremely low operating costs and supreme comfort for decades to come.

An art wall at the end of the foyer continues to withhold key views. The spaces expand upon moving into the house and open up to the dynamic views of the Atlantic and nearby salt marsh. Exterior cladding materials help create a story of a hard-black shell protecting the house from the harsh bay climate, with a warm welcoming core. Closer inspection shows the thick protective shell to be a deceptively light open-joint rain screen made of locally harvested and manufactured Shou Sugi Ban (charred) siding, selected for its unique texture and colour. Stained shiplap hemlock siding and orange detailing on windows and doors provides a warm counterpoint.

The single-level, 1,920 sf, two-bedroom residence is linked to a garage and storage shed by a gabled breezeway. An angular cut through the main house creates a sharp geometric volume for the living spaces, culminating in a west-facing indoor-outdoor porch. This dramatic slice of the form is oriented to a solar south axis and provides an important wall of windows to maximize solar gain. The layout provides an intentional, drawn out procession from entrance to ocean. It begins in a sheltered courtyard formed by the garage and house, buffering winter winds and the view.

The inviting

bright orange front door opens onto a foyer clad in uneven birch planks; a material theme continued throughout the house evoking the undulating waters of the bay.

These finishes are beautiful, functional, and free of volatile organic compounds (VOCs). A local supplier and mill practicing sustainable harvest practices supplied all the knotty spruce board and batten. The final mandate was to improve the old structure’s energy-efficiency while making comfortable workspaces for their growing team of staff and volunteers. To this end a highly permeable and energy-efficient wall assembly was designed to maximize longterm durability. A vapour profile evaluation and careful material selection ensured the wall wouldn’t trap moisture between the new exterior wall assembly and the two inches of existing impermeable rigid foam insulation on the inboard side of the existing wall. The entire building was wrapped in a new airtight weather barrier and three inches of exterior semi-rigid mineral wool. A minimum of two feet of cellulose insulation was added to the roof. Insulated steel door cut-outs were diverted from the waste stream and the polyurethane foam component was used as sub-slab insulation. The post-construction air tightness result of 1.4 air changes per hour (ACH) at 50 Pascal surpasses the R-2000 certification target of 1.5 ACH. The final result, a fully renovated three-storey, century-old building, uses 40% less energy than its former two-storey structure, even though building area was increased by 50%. In fact, as of 2017, the Ecology Action Centre Headquarters is the third most energy-efficient office building, and the most energy-efficient commercial office retrofit in Canada.

St. John’s, NL

First LEED Gold in the province a model for new development Located within steps of the St. John’s Harbour, it was inevitable that the development concept for 351 Water Street included using seawater as part of the plan for the building to be energy efficient and environmentally sustainable. Three drilled wells in the basement of the building connected to the building heat pump equipment, allow the use of the ground water that flows in and out underneath the building for both heating and cooling.

EVOLUTION OF GREEN BUILDING AT DALHOUSIE 1

Dalhousie is celebrating its 200th year anniversary in 2018! With a two-century history, the university has been and is a major building owner with approximately 150 buildings and houses on four campuses in Halifax and Bible Hill, Nova Scotia.

By Rochelle Owen, Executive Director Office of Sustainability

Fundamental green building concepts can be found in all types and ages of buildings from elegant design that maximizes durability, simplicity, smooth systems integration, and passive methods for light, heat and cooling. Green building can have many benefits including lower total cost of ownership, improving workplace well-being, reducing environmental and health impacts, demonstrating reputational and community leadership, and supporting teaching and research. In the last decade, Dalhousie has created a more structured approach to green building in new construction and existing buildings. Dalhousie University passed a Sustainable Building Policy in 2011. For new construction, LEED Gold certification or higher is strived for. For existing buildings; internal programs, plans and directives provide direction for key green building action. Since 2010, six buildings have been built (Mona Campbell, Life Science Research Institute, Steele Ocean Science, LeMarchant Place, Wallace McCain Learning Commons, and Collaborative Health Education) with two more under construction (IDEA and the Fitness Centre). All eight buildings are LEED® Gold or Silver certified or are LEED® Gold or Silver candidate buildings. The fundamentals of green building such as good design, the use of passive strategies and high-efficiency systems and equipment are integral to every building. Some features will vary by building depending on the building site, type, and use. The design team for each building including architects, engineers, LEED consultants, construction managers and Dalhousie representatives identify the approach. Throughout the eight new Dalhousie buildings, several new initiatives and features have been or are being implemented including: • Sustainable sites: electric car charge stations, end-of-trip indoor and outdoor facilities, green roofs, white roof, naturalized vegetative areas, and permeable concrete. • Water efficiency: rain water cisterns, low-flow fixtures, and eliminating once through water cooled equipment. • Energy and Atmosphere: geo-exchange (ground source heat pumps), solar strategies (air heating-solar wall, hot-water heating solar thermal, electricity generation – solar photovoltaics and battery storage), variable refrigerant flow (VRF) heat-recovery heat-pump system, high-efficiency equipment and systems, triple-pane windows and higher than normal envelope insulation, LED lighting, active chilled beams, assembly water and air testing, measurement and verification, and enhanced commissioning.

signs, dashboards, sessions and information sheets. Part of our approach is using the campus as a learning, research and teaching environment. In one of the buildings, four houses came down as part of the construction. Part of the waste strategy was to achieve high rates of waste diversion and research the opportunity for job creation. In each house over 86% of materials were diverted from the landfill through salvage and recycling efforts. In one of the four houses, deconstruction processes were used. This involves dismantling the house systems to achieve cleaner material and higher diversion rates. In this particular house, deconstruction achieved a 93% diversion rate. This process created two more weeks of work with additional labour costs. One of the focuses of the published research report was to determine if reduced waste diversion costs would cover the cost of increased labour which results in higher recycling rates.

Faculty and students are involved in many aspects of green building teaching and research on and off campus including using data from Dal smart meters and building systems to create alarming methodology and maximizing control sequences. Smart metering is used on our full compliment of building stock dating from 1887 to present day. This type of data helps us to identify issues and take action in maintaining building performance targets. Staff have received LEED professional accreditation training and are a part of the Atlantic Chapter of the Canada Green Building Council (AC-CAGBC). Recently, facilities and sustainability staff presented on rain water cisterns at an AC-CAGBC lunch and learn. Presentation highlights

practices,

challenges and opportunities, operational protocols, and cistern performance and benefits. The Mona Campbell cistern provides on average 40-45% of the building water loads through toilet flushing of 1600-2000 m3 annually. As a learning institution, it is important that we model what we teach and continually learn, modify, and innovate. We are actively working on several building and district energy scale projects that will take us into the 200 century for the University.

Q LOFTS Integrated design and construction sets standard in performance and durability Q Lofts is a 72-unit condo building located in the north end of Halifax. The 12,600 m2 building is seven storeys stories above grade and one below. The project is in the final stages of LEED for Homes certification at the Platinum level. Every aspect of the building’s design – envelope, energy, and materials – minimizes environmental impact and improves long-term durability.

1 2

ENERGY The building’s innovative approach to energy savings begins with the building envelope. It features highly insulated ICF walls with effective insulation values of R-29, triple-glazed windows and doors, and thermally-broken balconies. A high-efficiency heat pump system heats and cools the building using a high mass radiant floor distribution system. This system also heats domestic hot water. The main circulator pumps for the building have ECM motors and run on variable frequency drives. Outdoor air is supplied to the condos through a high-efficiency rooftop energy recovery ventilator (ERV). Occupants of Q Lofts benefit from high efficiency appliances, LED and CFL lighting, and also the use of a cloud-based energy management/metering system. Heating/ cooling energy consumption is billed back to the suites to ensure accountability for energy use in the building. Occupancy sensors control lighting in the parkade. The EUI of 50.6 kWh/m2 is 48.6% better than the baseline MNECB 1997. HEALTH AND WELLNESS Good indoor air quality starts with minimizing emitting materials. Low-VOC hard flooring and paints were chosen and formaldehyde-free materials were used for trim and cabinetry. A very airtight building envelope also minimizes pollutants entering the building from the exterior. Ongoing indoor air quality is ensured using the highefficiency ERV system with high MERV air filtration that delivers fresh air to the unit and common areas. Superior acoustic comfort is ensured by separating the units from each other and from the exterior using extra mass drywall and acoustic clips, along with triple-glazed windows, doors and skylights and highly insulated ICF walls. The property is directly adjacent to Halifax’s main downtown area fire station which creates a large amount of neighbour noise yet is barely audible. Finally, the Q Lofts location in the vibrant north end urban core of Halifax close to many restaurants, stores and urban parks, including the Halifax Common with an outdoor speed skating rink and sports fields, encourages a healthy lifestyle.

THE BUILDING ENVELOPE CONSISTS OF INSULATED CONCRETE FORMS, TRIPLE-GLAZED WINDOWS AND DOORS, AND THERMALLY-BROKEN BALCONIES [1]. SUPERIOR ACOUSTIC COMFORT IS BUILT IN BETWEEN SUITES AND WITH THE EXTERIOR [2 AND 3]. AN INTEGRATED DESIGN AND CONSTRUCTION PROCESS HAS RESULTED IN THE MOST ENERGYEFFICIENT MULTI-UNIT BUILDING IN ATLANTIC CANADA [4].

WATER The building incorporates low-flow fixtures and a landscape that requires little irrigation. Water usage in the suites is individually metered and billed to residents. Studies have shown that hot and cold water use decreases on average 15% when individually metered. Rainwater is collected from the building’s roof and stored in a 45,000litre rainwater cistern located under the floor of the parking garage for use in toilet flushing. It is expected that 100% of the toilet water supply requirements will be fulfilled with rainwater and not from the municipal water supply. The owner, POLYCORP, ensured that the design and construction process was integrated so that Q Lofts is, by far, the most energy efficient and green multi-unit building built in Atlantic Canada. Leading by example, Q Lofts is showing other developers in the region what can be done, and it is helping to move the market towards more high-performance green buildings.

KEEPING WITH TRADITIONAL DESIGN A trullo (plural, trulli) is a traditional Apulian dry stone hut with a conical roof. Their style of construction is specific to the area of the Italian region of Apulia. Trulli were generally constructed as temporary field shelters and storehouses or as permanent dwellings by small proprietors or agricultural labourers. In the town of Alberobello, in the province of Bari, whole districts are packed with trulli. The golden age of trulli was the 19th century, especially its final decades marked by the development of wine growing. A typical trullo has a cylindrical base with a conical limestone-tiled roof. Though built without cement, their thick white4 FLOOR PLAN

painted stone walls ensured coolness in the summer and warmth in the winter.

RESULT The design of the restaurant was based on the natural elements of a trullo with ceiling domes, natural stone look, wood and concrete elements for a cozy contemporary feel. Products were carefully chosen to create the modern

The project is a new restaurant located in a highly desired area in Dartmouth located at King’s Wharf Place. This area is continuously developing and has to date three condominium building and one apartment complex with all buildings having commercial leased spaces on the ground level. The restaurant is located in the Aqua Vista building at the edge of the development which provides the best views. The location is ideal as it provides the guest with a great waterfront view of the Halifax Harbour and views of the Dartmouth water for our kitchen staff. The name of the restaurant is a symbol of the owner’s region of Puglia in the south of Italy.

STRATEGIC DECISIONS Location is very important for this industry and the owners took over a year before choosing the right one. The development was up and coming and Il Trullo is providing a service that was missing from the area to make it flourish and possibly attract new developments.

COMMUNITY Its important to provide local services that the residence can walk to. There are 300 + residence in the development and another 1200+ within a 5 block radius. Il Trullo also takes part of local block parties and supports local charities.
