Building envelopes and materials
High performing building envelopes reduce heat gain as well as heat loss, lowering energy requirements. Materials commonly used to keep buildings warm in colder months also store heat in warmer months (e.g. concrete, tiles, brick, and stone).
Incentivize developers and property owners to incorporate elements for envelope efficiency such as through zoning bonuses or expedited review.
Considerations for Use
This is most applicable to new developments. Improving existing building envelopes is often cost prohibitive, but owners can consider improving insulation and airtightness during major renovations.
