RND Construction – A Leader in Energy Efficient and Environmentally Friendly Homes
The Phoenix Project – GOHBA Innovation Award Green Custom Home of the Year 2018
This award-winning project is a single-family home designed using Passive House concepts to achieve a Net Zero Ready home. Named The Phoenix Project to record the fact that fire rendered the previous house condemned. It is the perfect setting to demonstrate how houses should be built with careful consideration for the user, neighbourhood and environment.
Situated mid-block in a quaint Ottawa neighbourhood (Westboro) this project location is prime for sustainable living. With its proximity to main street shops, parkway bike paths, Ottawa’s transitway, it offers an opportunity to live without a vehicle or with little reliance on one. It is perfect for the client’s family with a walking lifestyle. The property has an east-west orientation and faces east, crucial for both Passive Solar and Passive Ventilation concepts. The site zoning easily supports the growth and flexibility required to change as the family grows. However, it is important to ARCA-VERDE to do so with as small a footprint (house size) as possible.
The client challenged ARCA-VERDE to arrange the house to permit natural light in every regularly occupied room or area. In addition to natural light, the client also requested maximal natural ventilation. The east to west orientation and house form allows light penetration and fosters natural airflow throughout. The form, as a result, is an expression that is elegant and unimposing.
We believe the result is a new architectural language celebrating the existing urban fabric, our environmental responsibility and the family’s needs. Three opportunities to produce something of merit.
The expansive interior views within the Phoenix Project are achieved by an open concept plan, allowing maximum penetration of natural light and offering few obstacles for natural ventilation. However, the open concept plan offers areas of repose and isolation. In either a spa-inspired washroom, private master bedroom or the studio space at the front of the house on the second floor, each is intended to be a place to seek when independence or recharge is needed.
It is an ARCA-VERDE desire that all operational equipment within a house has little to no visual presence. This can be difficult with sustainable ideals but in The Phoenix Project, it is achieved by allowing the architecture to be the first response. For example, rather than relying on equipment to heat, cool and ventilate, the building shape, interior configuration and placement of windows serve as the primary methods. Low operable windows permit fresh air and high operable windows permit ventilation. Careful placement of interior partitions and operable transoms eliminate obstacles. The east-west orientation with large windows facing south allows the winter sun to heat the interior eliminating almost all need for supplemental mechanical heat. This also allows adequate natural light in all rooms. The only interior room without a window uses a solar tube mounted to the roof to deliver natural light.
Age in Place and Functional Description
To allow for family growth and change The Phoenix House is prepared to receive simple upgrades to be truly barrier-free, allowing full accessibility to an aging residence. For example, the house has planned for an elevator with space for a shaft and thickening of the basement slab. The basement space is ready to receive a granny suite or secondary dwelling unit. A ramp, that has been planned, would be built to the front door.
While entertaining, the dining room is large enough to host 8-10 people with comfort. The kitchen is modest in size but has a large amount of storage and designed to be the hub of the house. A feature of the kitchen is a washroom, pantry and recycle center hidden behind kitchen cabinets. The living room is a formal area with conversational seating or a nice place to read the paper while morning light bathes the room.
The functional layout intends to be void of formal circulation. Overlapping functions foster a creative and friendly environment without bolstering the house size. Three fireplaces are located throughout to offer ambiance and on-demand heat source.
ARCA-VERDE has considered every detail in the Phoenix Project. The placement of functions and arrangement of space creates an economy of space. Designing with the environment in mind creates a home with a low impact on the earth, a bright interior, and reconnect occupants with the exterior environment. In the most basic of explanations, ARCA-VERDE turned each of the Phoenix Project’s challenges into an opportunity to develop something of merit.
