Holistic renovation of historic and heritage buildings: comparing New Zealand and international scenarios

Abstract

Purpose

Holistic renovation of historic and heritage buildings involving different stakeholders has the potential to reduce environmental impact. Climate change concerns are emphasizing environmental issues of cultural built heritage leading to new policies, guidelines and methods dealing with the challenge on how to lessen the environmental impact of built heritage without damaging its cultural significance. The purpose of this paper is to review existing international and New Zealand holistic guidelines for renovation of historic and heritage buildings.

Design/methodology/approach

A systematic review is used to identify international projects, methods and criteria within the holistic approach. Secondly, the New Zealand context is explored and compared with best international practices.

Findings

For instance, in New Zealand one increasingly important issue is the many vacant heritage and historic buildings in provincial town centres that need action to deal with building code seismic changes. Upgrades and adaptive reuse are opportunities to make them more sustainable and climate change resilient. However, the lack of national holistic guidelines regarding the challenge of reducing environmental impact whilst keeping the heritage values is a critical gap which urgently needs to be resolved. The need is further increased within the context of the recently passed Zero Carbon Act 2019, which aims for national zero carbon emissions by 2050.

Originality/value

These shared responsibilities for conserving historic and heritage buildings to maintain life in provincial towns on one hand, and the need to reduce greenhouse gas (GHG) emissions on the other, have the potential to contribute to a sustainable development of cities and communities.
