2001 - Sunny Woods
Sunny Woods was erected using a brand-new timber technology. Sunny Woods combines modern design with great living conditions. Sunny Woods was fitted with organic, toxic free materials offering a great place to live in tune with energy efficiency, sustainability and ecology. The external walls of approximately 40cm thickness consist of a load bearing blockboard of only 3.5cm, leaving plenty of space for thermal insulation. It is the first `Zero Heating` apartment complex using thin film solar modules installed across the roof. The roof is slighty south oriented and it is totally covered by 16.1 kWp of photovoltaic modules. They are able to provide about 15000 kWh of electricity every year that is injected into the grid of the electric company EWZ. This permits to reach the standard of passive house. During the heating period, the apartments are supplied with controlled ventilation with preheated fresh air, which is passed through a heat exchanger and, if necessary, heated by means of a heat pump.
SOLAR ARCHITECTURE
| Energy and architectural concept | – Energy optimized – Maximum power |
– Partially adapted to building skin – Roof |
– Partially adapted to building skin – Facade |
– Total building skin |
| Energy and architectural language | – Evident emphasized PV | – Low recognizable PV | – Hidden PV Mimicry |
SOLAR AND BUILDING SKIN
| Standardization vs customization | – Standard PV components | – Low customized components | – Highly customized components | |
| Building skin technology | – Roof added system | – Facade added system | – Roof integrated system | – Facade integrated system |
SOLAR AND BUILDING ENERGY CONCEPT
| Solar and building energy efficiency | – No special energy target | – Standard energy target – (state of art, normative) | – High energy efficiency – (Passive-house, n-ZEB, PEB) | |
| New building or refurbishment | – New building | – Refurbishment (ordinary building) |
SOLAR AND URBAN CONTEXT
| Solar and urban density | – Low-density building | – Medium-density urban context | – High-density urban context | |
